[Crustacea • 2017] Epimeria of the Southern Ocean with Notes on Their Relatives (Amphipoda, Eusiroidea) ---ScRaBBlE


Epimeria (Drakepimeria) loerzae
E. (Hoplepimeriaquasimodo 
E. (Drakepimeriacyrano 
d'Udekem d'Acoz & Verheye, 2017


Abstract

The present monograph includes general systematic considerations on the family Epimeriidae, a revision of the genus Epimeria Costa in Hope, 1851 in the Southern Ocean, and a shorter account on putatively related eusiroid taxa occurring in Antarctic and sub-Antarctic seas. The former epimeriid genera Actinacanthus Stebbing, 1888 and Paramphithoe Bruzelius, 1859 are transferred to other families, respectively to the Acanthonotozomellidae Coleman & J.L. Barnard, 1991 and the herein re-established Paramphithoidae G.O. Sars, 1883, so that only Epimeria and Uschakoviella Gurjanova, 1955 are retained within the Epimeriidae Boeck, 1871. The genera Apherusa Walker, 1891 and Halirages Boeck, 1891, which are phylogenetically close to Paramphithoe, are also transferred to the Paramphithoidae. The validity of the suborder Senticaudata Lowry & Myers, 2013, which conflicts with traditional and recent concepts of Eusiroidea Stebbing, 1888, is questioned. Eight subgenera are recognized for Antarctic and sub-Antarctic species of the genus Epimeria: Drakepimeria subgen. nov., Epimeriella K.H. Barnard, 1930, Hoplepimeria subgen. nov., Laevepimeria subgen. nov., Metepimeria Schellenberg, 1931, Pseudepimeria Chevreux, 1912, Subepimeria Bellan-Santini, 1972 and Urepimeria subgen. nov. The type subgenus Epimeria, as currently defined, does not occur in the Southern Ocean. Drakepimeria species are superficially similar to the type species of the genus Epimeria: E. cornigera (Fabricius, 1779), but they are phylogenetically unrelated and substantial morphological differences are obvious at a finer level. Twenty-seven new Antarctic Epimeria species are described herein: Epimeria (Drakepimeria) acanthochelon subgen. et sp. nov., E. (D.) anguloce subgen. et sp. nov.E. (D.) colemani subgen. et sp. nov.E. (D.) corbariae subgen. et sp. nov.E. (D.) cyrano subgen. et sp. nov.E. (D.) havermansiana subgen. et sp. nov.E. (D.) leukhoplites subgen. et sp. nov.E. (D.) loerzae subgen. et sp. nov.E. (D.) pandora subgen. et sp. nov.E. (D.) pyrodrakon subgen. et sp. nov.E. (D.) robertiana subgen. et sp. nov., Epimeria (Epimeriella) atalanta sp. nov., Epimeria (Hoplepimeria) cyphorachis subgen. et sp. nov., E. (H.) gargantua subgen. et sp. nov., E. (H.) linseae subgen. et sp. nov., E. (H.) quasimodo subgen. et sp. nov., E. (H.) xesta subgen. et sp. nov., Epimeria (Laevepimeria) anodon subgen. et sp. nov., E. (L.) cinderella subgen. et sp. nov., Epimeria (Pseudepimeria) amoenitas sp. nov., E. (P.) callista sp. nov., E. (P.) debroyeri sp. nov., E. (P.) kharieis sp. nov., Epimeria (Subepimeria) adeliae sp. nov., E. (S.) iota sp. nov., E. (S.) teres sp. nov. and E. (S.) urvillei sp. nov. The type specimens of E. (D.) macrodonta Walker, 1906, E. (D.) similis Chevreux, 1912, E. (H.) georgiana Schellenberg, 1931 and E. (H.) inermis Walker, 1903 are re-described and illustrated. Besides the monographic treatment of Epimeriidae from the Southern Ocean, a brief overview and identification keys are given for their putative and potential relatives from the same ocean, i.e., the Antarctic and sub-Antarctic members of the following eusiroid families: Acanthonotozomellidae Coleman & J.L. Barnard, 1991, Dikwidae Coleman & J.L. Barnard, 1991, Stilipedidae Holmes, 1908 and Vicmusiidae Just, 1990. This overview revealed the existence of a new large and characteristic species of Alexandrella Chevreux, 1911, A. chione sp. nov. but also shows that the taxonomy of that genus remains poorly known and that several ‘variable widespread eurybathic species’ probably are species complexes. Furthermore, the genera Bathypanoploea Schellenberg, 1939 and Astyroides Birstein & Vinogradova, 1960 are considered to be junior synonyms of Alexandrella. Alexandrella mixta Nicholls, 1938 and A. pulchra Ren in Ren & Huang, 1991 are re-established herein, as valid species. It is pointed out that this insufficient taxonomic knowledge of Antarctic amphipods impedes ecological and biogeographical studies requiring precise identifications. Stacking photography was used for the first time to provide iconographic support in amphipod taxonomy, and proves to be a rapid and efficient illustration method for large tridimensionally geometric species. A combined morphological and molecular approach was used whenever possible for distinguishing Epimeria species, which were often very similar (albeit never truly cryptic) and sometimes exhibited allometric and individual variations. However in several cases, taxa were characterized by morphology only, whenever the specimens available for study were inappropriately fixed or when no sequences could be obtained. A large number of Epimeria species, formerly considered as eurybathic and widely distributed, proved to be complexes of species, with a narrower (overlapping or not) distribution. The distributional range of Antarctic Epimeria is very variable from species to species. Current knowledge indicates that some species from the Scotia Arc and the tip of the Antarctic Peninsula are narrow range endemics, sometimes confined to one island, archipelago, or ridge (South Georgia, South Orkney Islands, Elephant Island or Bruce Ridge); other species have a distribution encompassing a broader region, such as the eastern shelf of the Weddell Sea, or extending from the eastern shelf of the Weddell Sea to Adélie Coast. The most widely distributed species are E. (D.) colemani subgen. et sp. nov., E. (E.) macronyx (Walker, 1906), E. (H.) inermis Walker, 1903 and E. (L.) walkeri (K.H. Barnard, 1930), which have been recorded from the Antarctic Peninsula/South Shetland Islands area to the western Ross Sea. Since restricted distributions are common among Antarctic and sub-Antarctic Epimeria, additional new species might be expected in areas such as the Kerguelen Plateau, eastern Ross Sea, Amundsen Sea and the Bellingshausen Sea or isolated seamounts and ridges, where there are currently no Epimeria recorded. The limited distribution of many Epimeria species of the Southern Ocean is presumably related to the poor dispersal capacity in most species of the genus. Indeed with the exception of the pelagic and semi-pelagic species of the subgenus Epimeriella, they are heavy strictly benthic organisms without larval stages, and they have no exceptional level of eurybathy for Antarctic amphipods. Therefore, stretches deeper than 1000 m seem to be efficient geographical barriers for many Epimeria species, but other isolating factors (e.g., large stretches poor in epifauna) might also be at play. The existence of endemic shelf species with limited dispersal capacities in the Southern Ocean (like many Epimeria) suggests the existence of multiple ice-free shelf or upper slope refugia during the Pleistocene glaciations within the distributional and bathymetric range of these species. Genera with narrow range endemics like Epimeria would be excellent model taxa for locating hotspots of Antarctic endemism, and thus potentially play a role in proposing meaningful Marine Protected Areas (MPAs) in the Southern Ocean.

[Entomology • 2017] Synonymy of Reikosiella Yoshimoto under Merostenus Walker (Hymenoptera: Chalcidoidea: Eupelmidae), with A Checklist of World Species and A Revision of Those Species with Brachypterous Females ---ScRaBBlE


Merostenus (Merostenuscongoensis 
Gibson, 2017 


Abstract

Reikosiella Yoshimoto, 1969 is synonymized under Merostenus Walker, 1837 n. syn. and treated as M. (Reikosiella), one of four subgenera recognized in the genus. Hirticauda Bouček, 1988, previously treated as a subgenus of Reikosiella, is synonymized under M. (Merostenus) n. syn., and two subgenera established in Reikosiella by Gibson (1995) are synonymized under Merostenus and treated as the subgenera M. (Capreocauda) and M. (Incohata) n. syns. The new generic synonymy is proposed after morphological comparison of females and males of Merostenus and Reikosiella sensu Gibson (1995), including reanalysis of features possessed by a basal group of genera of Eupelminae whose females share two hypothesized symplesiomorphies—a medially divided mesotrochantinal plate and lack of a mesotibial apical groove. A checklist of the 51 world species assigned to Merostenus is given, with 1 described species in M. (Incohata), 6 in M. (Capreocauda), 6 in M. (Reikosiella) and 38 in M. (Merostenus). All but one, the type species of Merostenus, represent new combinations. The species of Merostenus with brachypterous females are revised, with 8 of 10 species described as new. In addition to M. (Merostenus) excavatus (Dalman) (♀, ♂) from the Palaearctic, described in the same subgenus are one new species from Mexico, Merostenus (Merostenusmexicanus n. sp. (♀), and seven from the Afrotropical region, Merostenus (Merostenusdistigma n. sp. (♀: Kenya, Tanzania), Merostenus (Merostenusmicropterus n. sp. (♀: Democratic Republic of the Congo), Merostenus (Merostenusplatyscapus n. sp. (♀: South Africa), Merostenus (Merostenusreticulatus n. sp. (♀, ♂: Kenya), Merostenus (Merostenusspeculum n. sp. (♀: Burundi), Merostenus (Merostenuscongoensis n. sp. (♀: Democratic Republic of the Congo), and Merostenus (Merostenuslongistylus n. sp. (♀, ♂: South Africa). The first seven species are assigned to the excavatus species-group of M. (Merostenus) based on females sharing a completely sclerotized pronotum and apically truncate syntergum. Also treated is M. (Reikosiella) melinus (Yoshimoto) n. comb. (♀: Argentina, Brazil, Hawaii), the only species known with macropterous to variably strongly brachypterous females. Six species are transferred to other genera. Merostenus ferrugineus Yoshimoto & Ishii is transferred to Anastatus Motschulsky as A. ferrugineus (Yoshimoto & Ishii) n. comb., Merostenus guamensis Yoshimoto & Ishii and Merostenus palauensis Yoshimoto & Ishii are transferred to Eupelmus Dalman and provisionally classified in E. (Eupelmus) as E. (Eupelmus) guamensis (Yoshimoto & Ishii) n. comb. and E. (Eupelmus) palauensis (Yoshimoto & Ishii) n. comb., Eupelminus subapterus Ashmead is transferred to E. (Eupelmus) as E. (Eupelmus) subapterus (Ashmead) n. comb., and Eupelminus robustus Brues and Eupelminus tarsatus Waterston are transferred to Arachnophaga (Parasolindenia Brues) as Arachnophaga (Parasolindenia) robusta (Brues) n. comb. and Arachnophaga (Parasolindenia) tarsata (Waterston) n. comb. The character-state analysis and treated species are illustrated through macrophotography and, except for A. robusta, notes and illustrations provided for the excluded species to assist their future recognition.

[Mammalogy • 2018] Phenotypic Evolution in Marmoset and Tamarin Monkeys (Cebidae, Callitrichinae) and A Revised Genus-level Classification ---ScRaBBlE


Six genera of Callitrichinae: Callimico, Callithrix, Cebuella, Mico, Leontopithecus and Saguinus.

  Garbino & Martins-Junior, 2018. DOI: 10.1016/j.ympev.2017.10.002
Drawings by B. Rossi. 

Highlights
• First Platyrrhini phylogeny to use data from genic and non-genic nuclear regions.
• Vocalization and pelage traits presented strong phylogenetic signal.
• Phyletic position of the midas group of Saguinus is not resolved.
• First Callitrichinae classification using behavior, morphology, and molecular data.
• Proposal to divide Saguinus in the subgenera LeontocebusSaguinus and Tamarinus.

Abstract
Marmosets and tamarins (Cebidae, Callitrichinae) constitute the most species-rich subfamily of New World monkeys and one of the most diverse phenotypically. Despite the profusion of molecular phylogenies of the group, the evolution of phenotypic characters under the rapidly-emerging consensual phylogeny of the subfamily has been little studied, resulting in taxonomic proposals that have limited support from other datasets. We examined the evolution of 18 phenotypic traits (5 continuous and 13 discrete), including pelage, skull, dentition, postcrania, life-history and vocalization variables in a robust molecular phylogeny of marmoset and tamarin monkeys, quantifying their phylogenetic signal and correlations among some of the traits. At the family level, our resulting topology supports owl monkeys (Aotinae) as sister group of Callitrichinae. The topology of the callitrichine tree was congruent with previous studies except for the position of the midas group of Saguinus tamarins, which placement as sister of the bicolor group did not receive significant statistical support in both Maximum Parsimony and Bayesian Inference analyses. Our results showed that the highest value of phylogenetic signal among continuous traits was displayed by the long call character and the lowest was exhibited in the home range, intermediate values were found in characters related to osteology and skull size. Among discrete traits, pelage and osteology had similar phylogenetic signal. Based on genetic, osteological, pelage and vocalization data, we present an updated genus-level taxonomy of Callitrichinae, which recognizes six genera in the subfamily: Callimico, CallithrixCebuellaMicoLeontopithecus and Saguinus. To reflect their phenotypic distinctiveness and to avoid the use of the informal “species group”, we subdivided Saguinus in the subgenera LeontocebusSaguinus and Tamarinus (revalidated here).

Keywords: Leontocebus, Long call, Morphology, Subgenera, Tamarinus, Taxonomy, Vocalization

Conclusions
In this study, we demonstrated that vocalization and pelage characters can have a phylogenetic signal that is stronger than or comparable to the traditionally used osteological ones. Our robust phylogeny of callitrichinae shows that the position of the midas group of Saguinus is still unresolved.

This study is the first to offer a classification of Callitrichine that takes into account phylogenetic relationships, morphological, molecular and behavioral characters. As such, we propose that the phenotypic differences among the three clades of Saguinus are better represented in the group’s taxonomy by dividing the genus in three subgenera: Leontocebus, Saguinus and Tamarinus. Like any other taxonomic hypothesis, the one presented here is subject to testing, and future studies including additional characters may offer subsides to further divide the recognized genera or even elevate some of the subgenera to full genera.

[Botany • 2017] Thismia nigricoronata • A New Species of Burmanniaceae (Thismieae, Dioscoreales) from Vang Vieng, Vientiane Province, Laos, and A Key to Subgeneric Classification ---ScRaBBlE


Thismia nigricoronata  Kumar & S.W.Gale


Abstract

Thismia nigricoronata is described as a new species in family Burmanniaceae. Both morphological and phylogenetic analyses indicate that this new Lao endemic is allied to T. taiwanensis in section Glaziocharis, and it can be differentiated on the basis of its longer vestigial stem leaves, reflexed free outer perianth lobes and ornamented, vibrantly coloured outer surface of the perianth tube. The infrageneric taxonomy of Thismia is reviewed, the genera Geomitra and Scaphiophora are officially reduced to sectional status in Thismia, and all species are enumerated in systematic order. A key to all currently accepted subgenera, sections and subsections is presented to facilitate further examination of their phylogenetic integrity in light of apparent conflict between the traditional morphology-based system and the emerging DNA-based classification.

Keywords: achlorophyllous plants, Dioscoreaceae, holomycoheterotrophs, Laotian flora, Thismiaceae, Monocots

Thismia nigricoronata Kumar & S.W.Gale, sp. nov. 

Thismia nigricoronata is morphologically similar to Thismia taiwanensis but can be differentiated on the basis of its longer vestigial stem leaves (more than 6 mm long in the former versus less than 6 mm in the latter); its reflexed free outer perianth lobes (versus erect and projecting upwards in the latter); the ornamented outer surface of its perianth tube, which is verrucose below and papillose above (versus smooth and glabrous in the latter); and its vibrantly coloured perianth tube (versus translucent white in the latter).

 Habitat:— Thismia nigricoronata was discovered on a steep slope of a limestone mountain, growing among leaf litter in clayey soils under a dense evergreen canopy.

  Etymology:— The species epithet refers to the blackcrown-like structure formed above the annulus by the fusion of the three inner perianth lobes. Hence the taxon may informally be referred to as ‘the black-crowned thismia’.

Abstract

Perdita subgenus Heteroperdita Timberlake, a distinctive subgenus of 22 species from the southwestern United States and adjacent Mexico, all specialists on Tiquilia (Boraginaceae), is revised. Nine new species are described: Perdita (Heteroperdita) desdemona Portman, sp. n., P. (H.) exusta Portman & Griswold, sp. n., P. (H.) hippolyta Portman & Griswold, sp. n. (male previously incorrectly described as P. pilonotata Timberlake), P. (H.) hooki Portman & Neff, sp. n., P. (H.) nuttalliae Portman, sp. n., P. (H.) prodigiosa Portman & Griswold, sp. n., P. (H.) sycorax Portman, sp. n., P. (H.) titania Portman & Griswold, sp. n., and P. (H.) yanegai Portman, sp. n. The following sexes are associated and described for the first time: the male of P. (H.) frontalis Timberlake, 1968, the female of P. (H.) optiva Timberlake, 1954, and the true male of P. (H.) pilonotata Timberlake, 1980. Perdita (H.) fasciatella Timberlake, 1980 is proposed as a junior synonym of P. (H.) sexfasciata Timberlake, 1954. A neotype is designated for P. (H.) pilonotata Timberlake, 1980. Two species in particular, P. prodigiosa and P. pilonotata, are sexually dimorphic with distinctive ant-like males. Information is presented on floral relationships, phenology, and geographic distribution. Identification keys for males and females are provided.

[Botany • 2017] Taxonomic Revision of Sabicea Subgenus Anisophyllae (Ixoroideae, Rubiaceae) from Tropical Africa, with Four New Species ---ScRaBBlE


Sabicea sthenula 
 (N. Hallé) Razafimandimbison, B. Bremer, Liede & S.A. Khan


Abstract

A taxonomic revision of Sabicea subgenus Anisophyllae (Rubiaceae), a group restricted to Central and East Africa, is presented here. This work, based on a study of herbarium specimens and field observations in Cameroon and Gabon, includes a survey of the morphological features of the group, a key to the species, descriptions of all the taxa, and IUCN conservation status assessments. Fifteen species are recognised, four of which are described as new (Sabicea mapiana, S. ndjoleensisS. parmentieraeSsciaphilantha), three former varieties are raised to species rank (S. crystallinaS. jacfelicisStersifolia), and one species previously sunk into synonymy is restored (Sbequaertii). Two new infraspecific taxa are also described, Sabicea crystallina subsp. engongensis and S. sciaphilantha subsp. hirsuta. The group has its center of diversity in Gabon, where 10 of the 15 species occur, three of them being endemic to the country.

[Entomology • 2018] Revision of the Bee Group Anthophora (Micranthophora) (Hymenoptera: Apidae), with Notes on Potential Conservation Concerns and A Molecular Phylogeny of the Genus ---ScRaBBlE


Anthophora hololeuca Cockerell, 1923

in Orr, Pitts & Griswold, 2018. 

Abstract
Anthophora (Micranthophora) comprises the largest subgenus of Anthophora in the Western Hemisphere, with 26 species. Though previously synonymized with the Anthophora (Heliophila), Anthophora (Micranthophora) is here confirmed as a subgenus, morphological and multi-gene molecular phylogenetic evidence refute this and the synonymy of A. (Micranthophora) to A. (Heliophila) is formally rejected. Characters for (Micranthophora) are given and a key to species is provided. Seven new species are described: Anthophora (Micranthophora) caudata Orr, sp. nov.; Anthophora (Micranthophora) chihuahua Orr, sp. nov.; Anthophora (Micranthophora) escalante Orr, sp. nov.; Anthophora (Micranthophora) parkeri Orr, sp. nov.; Anthophora (Micranthophora) rara Orr, sp. nov.; Anthophora (Micranthophora) striata Orr, sp. nov.; and Anthophora (Micranthophora) timberlakei Orr, sp. nov. Further, four new synonyms are enacted: A. arthuri and A. flexipes to A. albata, A. nigritula to A. exigua, and A. xanthochlora to A. pachyodonta. Distributional and phenological data, as well as known details of nesting biology and floral specialization, are provided. Future research directions and species of potential conservation interest are also discussed. 

Keywords: Hymenoptera, Apoidea, Anthophorini, Heliophila, systematics, taxonomy, new species
