Abstract
Seven new species of the spider genus Ochyrocera from cave areas in Floresta Nacional de Carajás (state of Pará, northern Brazil) are described: Ochyrocera varys sp. n., Ochyrocera atlachnacha sp. n., Ochyrocera laracna sp. n., Ochyrocera aragogue sp. n., Ochyrocera misspider sp. n., Ochyrocera charlotte sp. n., and Ochyrocera ungoliant sp. n. Two groups of the species are discussed, the quinquivittata group that include specimens with an apparently bifid retrolateral apophysis in the cymbium of the male palp and the arietina group, here proposed, that include those specimens with an entire cymbium, with no retrolateral apophysis, in the male palp. Although these species were abundant inside caves, the examined specimens do not have troglomorphic characteristics and can be classified as edaphic troglophile species, capable of completing its life cycle in soil, shallow subterranean habitats, or caves.

Keywords: Amazonian region, Haplogynae, taxonomy

Taxonomy
Ochyrocera Simon, 1892
Ochyrocera Simon, 1892: 565
(Type species, O. arietina Simon)

Ceruleocera Marples, 1955: 462
 (Type species by original designation C. ransfordi Marples); Brignoli 1979: 598 (Syn.)

Diagnosis: Species of the genus Ochyrocera can be distinguished by having a tracheal spiracle between the epigastric fold and spinnerets (see Pérez-González et al. 2016: fig. 8A); clypeus sloping (Fig. 1A–B); tip of labium notched (Fig. 8E); long legs; male palp without tibial apophysis; cymbium conical and with prolateral extension, with or without apical cuspule; and flexed embolus projecting forward (Fig. 1C–D).

Composition: Thirty-nine species (World Spider Catalog 2017).

Distribution: With the exception of Ochyrocera ransfordi, described by Marples (1955) from Samoa, all described species are from Mexico, Cuba, Hispaniola, Lesser Antilles, Saint Vincent, Guatemala, Venezuela, French Guiana, Ecuador, Peru, Argentina, and Brazil.


• Ochyrocera varys sp. n.

Diagnosis: Ochyrocera varys resembles Ochyrocera atlachnacha in its carapace, which is yellow and bright lime (Figs 1A–B; 4A–B) and palp with conical, elongated cymbial apophysis, and have a distal cuspule on the cymbial apophysis (Figs 1C–D, 4C–D). This species can be distinguished by the male palp having a cymbial apophysis without an accentuated lateral projection (present in O. atlachnacha) and by the curved distal area of embolus (Figs 1C–D, 2C–F); females have a thick spermathecae enveloping large pore-plates (Fig. 1E–F).

Etymology: The specific name refers to Varys, a fictional character in George R. R. Martin’s book, “A Song of Ice and Fire”. Lorde Varys is a character with a venomous spirit, known as a spider in the plot.


Distribution: Recorded from caves and epigean areas of Carajás, state of Pará, northern Brazil (Fig. 19A).


• Ochyrocera atlachnacha sp. n.

Diagnosis: Ochyrocera atlachnacha resembles O. varys by its carapace yellow and bright lime (Figs 1A–B, 4A–B) and palp with conical, elongated and distal cuspule in the cymbial apophysis (Figs 1C–D, 4C–D). It can be distinguished from the latter and other Neotropical species by the male palpal cymbium with accentuated cymbial prolateral projection (Figs 4D, 5C, E–F); females have enlarged and projected pore-plates on the inconspicuous spermathecae (Fig. 4E–F).

Etymology: The specific name refers to Atlach-Nacha, a supernatural entity from Cthulhu mythology that resembles a huge spider with an almost human face.

Distribution: Recorded exclusively from caves in Carajás, state of Pará, northern Brazil (Fig. 20B).


• Ochyrocera laracna sp. n.

Diagnosis: Ochyrocera laracna resembles O. aragogue by the yellowish-green body pattern (Figs 7A–B; 8A−B) and by the short cymbial apophysis with two distal spurs on projections (Fig. 7C–D), a unique character for both these Neotropical species. The male of the former species can be distinguished from the latter due to the palp having a flap at the distal area of embolus (Figs 7C–D; 8A−B) and a laminar spur in the curved area 8F). The female is distinguished from O. aragogue by the small distal area of the spermathecae and pore plates adjacent to the spermathecae base (Fig. 7E–F).

Etymology: The specific name refers to Laracna, a giant and very old spider created by J. R. R. Tolkien in the classic book “The Lord of the Rings”.

Distribution: Recorded from caves and epigean areas in the Carajás region, state of Pará, northern Brazil (Fig. 20A).


• Ochyrocera aragogue sp. n.

Diagnosis: Ochyrocera aragogue resembles O. laracna by the yellowish green body color pattern (Fig. 10A–B) and by the short cymbial apophysis with two distal cuspules on projections (Fig. 10C–D, 11F), a unique character for both these Neotropical species. The male can be distinguished from O. laracna by the palp with a sinuous distal area of embolus without laminar spur (Figs 10C–D, 11A–B, D). The female has an enlarged distal area of spermathecae and pore plates at the spermathecae base (Fig. 10E–F).

Etymology: The specific name refers to Aragog, a spider capable of communicating with humans and a lover of human flesh, from the literary classic “Harry Potter and the Chamber of Secrets”, by J.K. Rowling.

Distribution: Recorded exclusively from caves in the Carajás region, state of Pará, northern Brazil (Fig. 19B).

 Ochyrocera misspider sp. n., couple in the web.

• Ochyrocera misspider sp. n.

Etymology: The specific name refers to Little Miss Spider, a very popular spider around the world and the main character of the children’s books by David Kirk.

Diagnosis: Ochyrocera misspider is the smallest among the species from Floresta Nacional de Carajás and resembles O. caeruleoamethystina Lopez & Lopez and O. thibaudi Emerit & Lopez by the small projection in the cymbium (see Lopez and Lopez 1997, fig. 8; Emerit and Lopez 1985, fig. 1A). It can be distinguished by the male palp with an elongated tibia, twice as long as the cymbium, and by the bifid embolus (Figs 13C–D, 14A–B). Females are distinguished from other species of the genus by the genitalia with a very long and narrow medial columnar uterus externus, internally with approximately 12 chambers, and an elongated, erect and sinuous spermathecae (Fig. 13F–G).

Distribution: Recorded exclusively from caves in the Carajás region, state of Pará, northern Brazil (Fig. 19B).


• Ochyrocera charlotte sp. n.

Diagnosis: Males and females of Ochyrocera charlotte sp. n. resemble those of O. ungoliant and O. viridissima Brignoli in having a subapical cuspule in the distal area of the cymbium (Fig. 17E−F; Brignoli 1974: fig. 6) but can be distinguished from these species by their yellowish cephalic area and cream body color pattern. Males can be distinguished by their pentagonal cymbium, with cylindrical tegulum (Fig. 17E–H). Females are diagnosed by the genitalia with a very narrow medial columnar uterus externus and an elongated and medially curved spermathecae (Fig. 17C–D).

Etymology: The specific name refers to Charlotte, the spider from the classic “Charlotte’s Web” by E.B. White and a great friend of the pig named Wilbur.

Distribution: Recorded exclusively from two caves in the Carajás region, state of Pará, northern Brazil (Fig. 20B).


• Ochyrocera ungoliant sp. n.

Diagnosis: Males and females of Ochyrocera ungoliant resemble those of O. charlotte and O. viridissima Brignoli in having a subapical cuspule in the distal area of the cymbium (Fig. 18G−H; Brignoli 1974: fig. 6), but can be distinguished from these species by their intense dark green color pattern and carapace with two longitudinal yellowish-green dorsal bands (Fig. 18A–B). Males can be diagnosed by their short cymbial apophysis with a very narrow tip and embolus with lamellar area in the distal third (Fig. 18E–H); and females by their genitalia with very short medial columnar uterus externus and spermathecae with broad and furrow apex (Fig. 18C–D).

Etymology: The specific name in apposition refers to Ungoliant, an evil spider spirit created by J. R. R. Tolkien in the book “The Silmarillion”.

Distribution: Recorded exclusively from three caves in the Carajás region, state of Pará, northern Brazil (Fig. 20A).

Abstract
An endemic genus of Madagascan spiders (Araneae, Archaeidae, Eriauchenius) is revised. All 20 species of Eriauchenius are described and keyed, of which 14 are new speciesEriauchenius andriamanelo sp. n., Eriauchenius andrianampoinimerina sp. n., Eriauchenius goodmani sp. n., Eriauchenius harveyi sp. n., Eriauchenius lukemacaulayi sp. n., Eriauchenius milajaneae sp. n., Eriauchenius milloti sp. n., Eriauchenius rafohy sp. n., Eriauchenius ranavalona sp. n., Eriauchenius rangita sp. n., Eriauchenius rixi sp. n., Eriauchenius sama sp. n., Eriauchenius wunderlichi sp. n., Eriauchenius zirafy sp. n. Additionally, six species of the new genus Madagascarchaea gen. n. are described and keyed, of which four are new species: Madagascarchaea fohy sp. n., Madagascarchaea lotzi sp. n., Madagascarchaea moramora sp. n., Madagascarchaea rabesahala sp. n. Diagnostic characters for the Madagascan and African genera are described, and based on these characters and previous phylogenetic analyses the following species transfers are proposed: Eriauchenius cornutus (Lotz, 2003) to AfrarchaeaAfrarchaea fisheri (Lotz, 2003) and Afrarchaea mahariraensis (Lotz, 2003) to Eriauchenius. Finally, we propose that the distribution of Afrarchaea be restricted to South Africa. While several Madagascan specimens have previously been identified as Afrarchaea godfreyi (Hewitt, 1919), we argue that these are likely misidentifications that should instead be Eriauchenius.

Keywords: Afrarchaea, Palpimanoidea, new species, taxonomy


Suspended upside-down from a strand of silk, the male of species Eriauchenius workmani (right) slowly approaches the female (left) to mate. As he approaches, he makes sounds by quickly vibrating his pedipalps (a small, modified pair of legs) to court the female. She answers back by vibrating her pedipalps.

[Arachnida • 2018] The Cave-dwelling False Scorpion Genus Pseudoblothrus Beier, 1931 (Pseudoscorpiones: Syarinidae) in the Crimean Peninsula ---ScRaBBlE


Pseudoblothrus roszkovskii  (Redikorzev, 1918)

in Kolesnikov & Turbanov, 2018.

Abstract 

Based on morphological and molecular studies of material from caves in three karst regions of Crimea, the small, apparently relictual, Euro-Mediterranean and Macaronesian false scorpion genus Pseudoblothrus Beier, 1931 is shown to contain only one troglobiont species there, P. roszkovskii (Redikorzev, 1918), of which P. ljovuschkini Krumpál, 1984 and Obisium tauricum Lebedev, 1927 are junior subjective synonyms. A detailed redescription of the adults and tritonymph of P. roszkovskii is provided, together with phylogenetic and zoogeographical analyses.

Keywords: Pseudoscorpiones, variation, taxonomy, phylogeny

[Arachnida • 2017] Kryptonesticus deelemanae gen. et sp. nov. (Araneae, Nesticidae), with Notes on the Mediterranean Cave Species ---ScRaBBlE


Kryptonesticus deelemanae 
Pavlek & Ribera, 2017 
 DOI:  
10.5852/ejt.2017.262 

Abstract

This paper describes and illustrates a new genus and a new species belonging to the family Nesticidae based on morphology and supported by molecular data. The new genusKryptonesticus gen. nov., groups eight species spread from Bulgaria and Turkey to Croatia, including Montenegro, Bosnia and Herzegovina and Crete. As a result, seven new combinations are proposed: K. eremita (Simon, 1879) comb. nov., K. arenstorffi (Kulczyński, 1914) comb. nov., K. fagei (Kratochvíl, 1933) comb. nov., K. beroni (Deltshev, 1977) comb. nov., K. beshkovi (Deltshev, 1979) comb. nov., K. henderickxi (Bosselaers, 1998) comb. nov. and K. dimensis (López-Pancorbo, Kunt & Ribera, 2013) comb. nov., all ex Nesticus. Kryptonesticus deelemanae gen. et sp. nov. is described on the basis of both sexes and its phylogenetic relationships with closely related species are discussed based on morphological and molecular data (the cox1, rrn and H3 genes). In addition, the species of this new genus (except for K. eremita) are clear candidates for protection: they have highly restricted ranges and some of them show a high degree of adaptation to the subterranean environment.

Keywords: Nesticidae; taxonomy; caves; endemism; Dinarides

Order Araneae Clerck, 1757

Family Nesticidae Simon, 1894
Kryptonesticus gen. nov.

Type species
Kryptonesticus deelemanae gen. et sp. nov. 

Etymology: The prefix “Krypto”, from Ancient Greek κρυπτός (kruptós “hidden”), alludes to the long time it took to diagnose this evolutionary line.

Distribution:From Bulgaria and Turkey to Croatia, including Montenegro, Bosnia and Herzegovina and Crete. All these species are known only from the type locality, or have small distribution ranges. K. eremita is an exception; this species is linked to human activities and can be found in hangars, cellars and cottages. It has been cited from France and Italy to Bulgaria and Turkey. It is a potentially invasive species, found in an abandoned air-raid tunnel in Auckland, New Zealand (Vink & Dupérré 2011).

Krypyonesticus deelemanae gen. et sp. nov.

Etymology: The specific name is a patronym in honor of Christa Laetitia Deeleman-Reinhold, an important Dutch arachnologist and a dear friend. Her work has vastly raised the knowledge of the cave spider fauna of Dinarides. The species name is in possessive genitive.

  Distribution: The new species is endemic to Croatia; it is distributed on Biokovo Mt in central Dalmatia, a coastal region in Croatia. So far it has been recorded in 20 caves scattered through the whole mountain, from the south-west sea side to the north-east continental side, from the 310 to 1640 asl (Fig. 6A). Data on all records of K. deelemanae gen. et sp. nov. are given in Appendix 2. The distribution area of K. deelemanae gen. et sp. nov. is more than 80 km away from that of K. fagei and more than 100 km from that of K. arenstorffi (Fig. 6B). 

Natural history: The type locality, Samogorska špilja, is a small cave with two entrances (Fig. 7). On the date of the last collection, 23 Jan. 2016, the air temperature in the cave was 0.5°C with cold air streaming through the cave, mostly near the cave floor. Spiders were found freely walking on the ceiling of the chamber (probably avoiding the cold air flow at the bottom) and on the side walls of the cave. The temperature in other caves where K. deelemanae gen. et sp. nov. is found ranges from 0 to 15°C. Some of those caves are very small and are greatly influenced by outside conditions (like the type locality), while the others are quite big, have a true cave microclimate and harbor diverse types of cave habitats (for example Pretnerova jama, a 254-meter deep pit). No other nesticid species are found in caves on Biokovo Mt.

Abstract

large white species of wolf spider, Ocyale ghost Jocque M. & Jocqué R. sp. nov., is described from a white sandy beach of an inland freshwater lake in the northwest of Madagascar. The first photos of a living specimen of the genus Ocyale are provided together with some observations on the biology of the newly described species. An updated and illustrated key to the Afrotropical species of Ocyale is included here.

Keywords:  beach; biology; phenology; white sand

Ocyale ghost Jocque M. & Jocqué R. sp. nov.

Diagnosis: Males of Ocyale ghost sp. nov. can be recognized by details of the male palp: the tegulum is restricted to the prolateral side of the bulbus, the distal prong of the palea appendage is much narrower than the proximal one and the MA with the perpendicular prong is rectangular. Females are characterized by the epigyne in which the T-shaped posterior sclerite is fully exposed and not covered with setae as in other species in the genus. 

Etymology: The species name ‘ghost’ refers to the fully white appearance of this spider. Additional reference is made to the large white direwolf ‘Ghost’ in Game of Thrones, the first book in the series of fantasy novels A Song of Ice and Fire by George R.R. Martin.  

Biology: Ocyale ghost sp. nov. was only found on the white sandy beaches (Fig. 3A–B) of an inland lake in the study region. The surveys also included grassland and dry forest, but the species seems restricted to a white-sand habitat, as reflected in its habitus. Ocyale ghost sp. nov. is active at night and all specimens were caught with headlamps after sunset. Captured animals that were kept alive in large ziplock bags overnight constructed retreats in the sand, lined with silk (Fig. 3C). Possible prey include large insects such as grasshoppers (Fig. 3F) that also exhibit camouflage colours as an adaptation to the white beach they live on. Intraspecific predation is also likely to occur (Fig. 3E), a phenomenon which is not unusual among lycosids (Edgar 1969; Hallander 1970). We observed copulation and females with spiderlings (Fig. 3D) in the midst of the dry season (June–July). Juveniles of a complete range of size, from very small ones (6 mm TL) to subadults, were observed, indicating that this species might reproduce yearround. The permanent presence of water in its habitat might explain why this species is also active in the dry season when spider activity is on average very low.
