Abstract

Until recently the genus Cynomops (Chiroptera: Molossidae) comprised six species of fast flying, aerial insectivorous bats distributed throughout the Neotropics. However, our revisionary study have shown that the diversity of this taxon was underestimated as molecular and morphological data supported the recognition of C. milleri as a full species and revealed two previously unrecognized, small species of Cynomops. These newly recognized taxa are Cynomops freemani sp. nov. from the Canal Zone region, Panama, sister taxon to C. mexicanus, and Cynomops tonkigui sp. nov. from the eastern Andes of Ecuador and Colombia, sister taxon of C. milleri. We also describe the calls of Cynomops freemani sp. nov. that may be useful for the recognition of these species during field inventories based on ultrasonic recording techniques. We elevate the currently known diversity of Cynomops to eight species, as we also revalidate C. milleri providing an emended diagnosis and a redescription of this taxon.

[Herpetology • 2018] Nototriton costaricense • A New Moss Salamander, Genus Nototriton (Caudata: Plethodontidae), from the Cordillera de Talamanca, in the Costa Rica-Panama Border Region ---ScRaBBlE

Nototriton costaricense Arias & Kubicki, 2018

DOI: 10.11646/zootaxa.4369.4.2

CRAmphibian.com

Abstract

A new salamander belonging to the genus Nototriton, subgenus Nototriton, is described from the Caribbean slopes of the southeastern Cordillera de Talamanca in Costa Rica, within Parque Internacional La Amistad, at an elevation ca. 1500 m a.s.l. This new taxon is distinguished from its congeners by its morphological characteristics and by its differentiation in DNA sequences of the 16S rRNA, cytochrome oxidase subunit I (COI), and cytochrome b mitochondrial genes. This new species represents the southernmost extension known for the genus Nototriton.

Keywords: Amphibia, caudate, Central America, Nototriton picadoi species group, Talamanca

Southern Moss Salamander

....

Etymology. The specific epithet refers to the Spanish word meaning Costa Rican, “costaricense”. The name represents the fact that the holotype and species was discovered in Costa Rica. Given the close proximity of the type locality to the Costa Rica-Panama border, we speculate that one day it may indeed be discovered within Panama as well.

[Cnidaria • 2018] Revision of the Genus Adelogorgia Bayer, 1958 (Anthozoa: Octocorallia) with the Description of Three New Species ---ScRaBBlE

Adelogorgia osculabunda, A. hannibalis & A. adusta

Breedy & Guzman, 2018

DOI: 10.11646/zootaxa.4369.3.2

Abstract

The genus Adelogorgia is distinguished from other holaxonians in having conspicuously ornamented double-disc sclerites and leaf clubs in the coenenchyme, and non-mineralised axis cores. The two eastern Pacific species currently recognised as Adelogorgia are diagnosed and illustrated. Three new species for the genus are described from new localities and depth ranges. Analysis of external and internal characters, especially sclerite colours and sizes, and colony colour, shape and branching, allows separating the species. An identification key to the five species is provided, as well as a character table for comparisons. This study was based on newly collected specimens from 50 to 200 m deep, and re-examination of all historical material. We conclude that the genus comprises five valid species with a wider distribution than previously reported. This research is a contribution to the octocoral systematics and biodiversity from mesophotic and deep waters.

Keywords: Anthozoa, Adelogorgia, Alcyonacea, biodiversity, eastern Pacific, plexaurid, soft corals, taxonomy

Class Anthozoa Ehrenberg, 1834
Subclass Octocorallia Haeckel, 1866

Order Alcyonacea Lamouroux, 1816
Family Plexauridae Gray, 1859

Genus Adelogorgia Bayer, 1958
Adelogorgia Bayer, 1958: 46; Bayer 1978: 1026–1027; Harden 1979: 137.

Type species. Adelogorgia phyllosclera Bayer, 1958 by original designation Type locality. La Jolla, California. Diagnosis (modified from Bayer, 1958; 1978). Colonies bushy, fan-shaped or sparsely branched. Branching lateral, irregular, or dichotomous; with moderately thick coenenchyme; polyps fully retractile, communicating directly with the longitudinal canal system (gastrodermal canals, solenia); anthocodia with eight subtentacular points consisting of spinous rods, not forming a distinct collaret. Polyp mounds prominent, slightly raised or flat, without specific types of sclerites, but leaf clubs concentrated around polyp apertures. Outer coenenchyme with conspicuous double discs with expansions on one side having various degrees of ornamentation; tuberculate spindles and leaf clubs. Axial sheath containing less developed spindles, radiates and capstans. Axis with wide cross-chambered central core. Loculi between lamellae and central core without mineralised filaments. Colony colours white, lemon-yellow, pink, orange and various hues of red. Sclerites of the same colours and colourless.

Distribution. The species has been reported from La Jolla, California, USA; Galápagos Islands, Ecuador (Bayer 1958, 1978); Baja California, Mexico (Harden 1979); and recently found along Pacific coast of Costa Rica and off Pacific coast of Panamá. Reported from 30 to 300 m deep (Cairns et al. 2002).

Adelogorgia osculabunda sp. nov.

Habitat and Distribution. The species has been collected by bottom trawls from sandy or muddy-sand substrata. It was also obtained from fishing lines and nets from rocky shoals, where the colonies were ripped as bycatch or were entangled in the lines from 40 to 60 m deep. Adelogorgia osculabunda was commonly collected together with Leptogorgia regis Hickson, 1928, Muricea fruticosa Verrill, 1868, Muricea subtilis Breedy and Guzman, 2016 and two Psammogorgia species. The species was found at various localities in Costa Rica, from: off Salinas Bay and Santa Elena Bay to Cape Santa Elena, Guanacaste (northern Pacific); and Punta Mala, Puntarenas (central Pacific) that suggests a wide distribution of the species along the Pacific. In Panamá, Pearl Islands, the colonies were obtained by dredging at 80 m deep, which presently represents the deepest record.

Etymology. Named osculabunda, Latin adjective derived from osculum: little mouth, kiss. In Latin context, osculabunda is the one that covers with kisses, in allusion to the red prominent polyp-mounds that cover the branches. Remarks. This species is similar to A. hannibalis in the prominent polyp-mounds showing a little darker orange contrasting with the colony colour, but is not as evident as in A. osculabunda. Thinner colonies of A. osculabunda look similar to A. hannibalis, but in A. osculabunda, the polyp-mounds are closer and stiffer than in A. hannibalis. Additionally, sclerite analysis shows clear differences between the two species.

(A) colony; (B) detail of the branches; (C) sclerites.

Adelogorgia hannibalis sp. nov.

Habitat and Distribution. The species was found on the Hannibal Bank, a coastal guyot-type seamount that rises from approximately 500 m to 45 m, located 50 km from the mainland (Cunningham et al. 2013). The seamount is relatively protected as part of the Coiba National Park and World Heritage. The species was found on rocky substrate with strong currents. It is only known from the type locality, Hannibal Bank, from 180 to 200 m deep.

Etymology. Named after the Hannibal Bank and the surveyor USS Hannibal that discovered and charted the bank for the first time, presumably in 1934. The name Hannibal evokes the Carthaginian general, considered one of the greatest military commanders in ancient history. In genitive: hannibalis (L) meaning ¨of Hannibal¨.

Adelogorgia adusta sp. nov.

Habitat and Distribution. The species was found in the Hannibal Bank, on rocky substrates impacted by currents. Adelogorgia adusta is only known from the type locality Hannibal Bank, from 73 to 94 m deep.

Etymology. Named adusta, Latin adjective meaning burnt, scorched, charred, in allusion to the burnt appearance that the colony takes after fixation. The word adustus, in Castellan language, adusto, was evoked in verse 62 of The Fable of Polifemo and Galatea (Spanish poet Luis de Góngora) referring to the son of the Pirineo (giant mount) who supposedly was put in flames

[Botany • 2017] Heliconia berguidoi • A New Species of Heliconia (Heliconiaceae) with Pendent Inflorescence, from Chucantí Private Nature Reserve, eastern Panama ---ScRaBBlE

Heliconia berguidoi

R.Flores, C.Black & A.Ibáñez

DOI: 10.3897/phytokeys.77.11190

Abstract: Heliconia berguidoi (Heliconiaceae), a new species from premontane forest of eastern Panama, is described, illustrated and its conservation status evaluated. H. berguidoi bears pink flowers, an uncommon color in this group. It differs from the Colombian species Heliconia rhodantha and Heliconia sanctae-theresae, the most similar taxa, by the combination of a petiole glabrous except for the woolly base, a very long peduncle, the perianth pubescent at the apex and staminode with cuspidate apex. H. berguidoi is also similar to Heliconia pogonantha in all four of its varieties and to Heliconia ramonensis in two of its four varieties, but differs by a combination of the long peduncle, pink flowers and staminode with cuspidate apex. Fifty-six Heliconia species have been found in Panama, eighteen of them endemic.

Taxonomic treatment

Heliconia berguidoi R.Flores, C.Black & A.Ibáñez, sp. nov.

Diagnosis: This species is distinguished from other species of Heliconia by the combination of the long petioles (up to 180 cm), glabrous but woolly at the base; blade splitting into narrow lateral segments; peduncle red, woolly with golden hairs, very long (125-150 cm); slightly flexuous rachis; bracts spirally arranged; pink flowers, perianth pubescent at the apex and staminode with cuspidate apex.

Type: PANAMÁ. Provincia de Darién: Reserva privada Chucantí, Sendero al filo (roca grande). Bosque premontano. 900 m. 8°47'33.46"N, 78°27'6.72"W, 26 agosto 2006, individuo colectado por Carla Black. Floreció en cultivo el 12 de marzo de 2016, Finca las Chichicas, corregimiento de Volcán, distrito de Bugaba, Provincia de Chiriquí. Col. R. Flores, O. Ortiz y C. Black, 3855 RF (Holotype PMA!, Isotype, MO!, SEL!, UCH!, US!).

Etymology: The specific epithet, berguidoi, honors the Panamanian biologist Guido Cesar Berguido F., who first brought national attention to Cerro Chucantí after witnessing not only its natural splendor, but the rampant ongoing deforestation. He mustered support from family and friends to purchase a property and set it aside for conservation before the previous owners could burn the forest to ashes. He received further private support and acquired more lands to create the Chucantí Private Nature Reserve. Mr. Berguido continues to invite fellow biologists to study the flora and fauna of Cerro Chucantí, which has resulted in the discovery of various species new to science. He recently founded the Asociación Adopta el Bosque Panamá, Adopt a Panama Rainforest, ADOPTA (www.chucanti.org) to further his conservation mission. It is an honor to thus recognize Mr. Berguido´s contributions to increased biological knowledge and his great efforts to conserve the unique forests of Cerro Chucantí. His generous logistical assistance to the authors was invaluable.

Resumen: Heliconia berguidoi (Heliconiaceae), una nueva especie de bosque premontano del este de Panamá, es descrita, ilustrada y su estado de conservación evaluado. H. berguidoi tiene flores rosadas, color poco común en este grupo. Difiere de las especies de Colombia Heliconia rhodantha y Heliconia sanctae-theresae, taxones más similares, por la combinación de un pecíolo glabro aunque lanudo en la base, pedúnculo muy largo, ápice del perianto pubescente y estaminoide con el ápice cuspidado. H. berguidoi es también similar a Heliconia pogonantha en sus cuatro variedades y a Heliconia ramonensis en dos de sus cuatro variedades, pero difiere por la combinación de su largo pedúnculo, el color rosado de las flores y el estaminoide con ápice cuspidado. En Panamá se han encontrado cincuenta y seis especies de Heliconia, dieciocho de ellas endémicas.

[Crustacea • 2017] Strongly Carinate Species of Alpheopsis Coutière, 1897 (Malacostraca: Decapoda: Alpheidae) of the Tropical Atlantic and eastern Pacific, with Redescription of A. trigona (Rathbun, 1901) and Description of Three New Species ---ScRaBBlE

Alpheopsis paratrigona Anker, 2017

DOI: 10.11646/zootaxa.4277.2.2

Abstract

The present study deals with four species of the alpheid shrimp genus Alpheopsis Coutière, 1897 characterised by the presence of at least one strong carina on the dorsal surface of the carapace. Alpheopsis trigona (Rathbun, 1901) is redescribed based on the holotype from Puerto Rico and additional material from US Virgin Islands and Florida. Two new species closely related to A. trigona, viz. Alpheopsis paratrigona sp. nov. and Alpheopsis gotrina sp. nov., are described, the first based on material from several localities in the tropical western Atlantic, and the second from the Pacific coast of Panama and Colombia. The three species together form a distinctive transisthmian clade within Alpheopsis, the A. trigona species complex, characterised by the presence of several strong longitudinal carinae on the carapace and very distinctive colour pattern. A more distantly related species, Alpheopsis aristoteles sp. nov., characterised by the presence of only one strong mid-dorsal carina in the anterior region of the carapace, is described based on material from São Tomé Island in the tropical eastern Atlantic.

Keywords: Crustacea, Caridea, marine shrimp, biodiversity, East Pacific, West Atlantic, East Atlantic, Caribbean Sea, Gulf of Guinea

Taxonomy

Family Alpheidae Rafinesque, 1815

Alpheopsis Coutière, 1897

Alpheopsis paratrigona sp. nov.

Etymology. The specific name refers to the general resemblance of the new species to A. trigona.

[Crustacea • 2017] Synalpheus pinkfloydi • A New Pistol Shrimp (Decapoda: Alpheidae) from the tropical eastern Pacific ---ScRaBBlE

Synalpheus pinkfloydi

Anker, Hultgren & de Grave, 2017

DOI: 10.11646/zootaxa.4254.1.7

Abstract

A new, conspicuously coloured species of the alpheid genus Synalpheus Spence Bate, 1888, is described based on material collected on the Pacific coast of Panama. Synalpheus pinkfloydi sp. nov. is closely related to the western Atlantic S. antillensis Coutière, 1909, the two taxa being transisthmian, cryptic sister species. Both species are characterised by the distal areas of their major and minor chelae coloured in an intense, almost glowing pink-red. The morphological differences between S. pinkfloydi sp. nov. and S. antillensis Coutière, 1909 are subtle, being limited to the slightly different proportions of the merus of both chelipeds, distodorsal armature of the major cheliped merus, relative length of the antennal scaphocerite, and body size. However, they are genetically different with a 10.2% sequence divergence in COI. Based on molecular clock estimates, these transisthmian taxa diverged around 6.8–7.8 mya, i.e. well before the final closure of the Isthmus of Panama 2.5–3 mya.

Keywords: Crustacea, Malacostraca, Caridea, snapping shrimp, Pacific Ocean, transisthmian taxa

FIGURE 3. Synalpheus pinkfloydi sp. nov., habitus and colour in life, holotype male (MZUSP 33778), Las Perlas Archipelago, Panama.

Photographs by A. Anker.

Etymology. Named after the well-known British rock band Pink Floyd, inspired by the bright pink-red claw of the new species.

Suggested vernacular name: Pink Floyd Pistol Shrimp.

Type locality. Las Perlas Archipelago, Bay of Panama.

Distribution. Presently known only from the type locality on the Pacific side of Panama; likely more widespread in the tropical eastern Pacific, but unlikely to occur on the Dark Side of the Moon due to lack of suitable habitat.
