On new or poorly known Australian Filistatidae spiders (Araneae: Araneomorphae), including a study on the fine morphology of Wandella

I present an update on the taxonomy of the filistatid genera Wandella Gray and Yardiella Gray, both endemic to Australia. Two new species are described: Wandella grayi sp. nov., known from Queensland, and Wandella infernalis sp. nov., known from a single cave in Western Australia. The male of Wandella australiensis (L. Koch) and the females of Wandella stuartensis Gray and Wandella waldockae Gray are described and illustrated for the first time. New records are given for these and other species of Australian filistatids, including the first epigeal records of Yardiella humphreysi Gray, a species so far known only from caves. Updated distribution maps are presented. Additionally, I present novel morphological data for Wandella using light and scanning electron microscopy. The cephalothorax, spinning organs, genitalia and appendages of some species are illustrated in detail. I report the presence of a putative claw extensor muscle in the male palpal cymbium, and describe interesting modifications in the clypeal region of adult males. The phylogenetic significance of these characters is briefly discussed.     

Two new species of the genus Alloclubionoides (Araneae: Amaurobiidae) in Korea

Two new species of the genus Alloclubionoides from two National Parks of Korea are described with detailed illustrations, leg spination, trichobothrium patterns and scanning electron micrographs. Alloclubionoides wolchulsanensis sp. nov. can be distinguished from other Alloclubionoides spiders by a heart-shaped conductor with rounded base in the male palp and a large genital opening situated in the middle of the atrium, and a broadly cylinder-like copulatory duct in female. Alloclubionoides jirisanensis sp. nov. resembles Alloclubionoides napolovi (Ovtchinnikov, 1999 Zhang, ZS, Zhu, MS and Song, DX. 2007. Three new species of the genus Ambanus Ovtchinnikov, 1999 from China (Araneae: Amaurobiidae: Coelotinae). Zootaxa., 1425: 21–28.  [Google Scholar]) but can be distinguished from it by the ‘Y’-shaped conductor dorsal apophysis and wound distal part of conductor.     

Aspects of the activity rhythm and population size of troglophilic mygalomorph spiders (Trechona sp., Dipluridae) in a quartzite cave in Minas Gerais,Brazil

Records of mygalomorphs inhabiting caves have increased in the past years. We present data on a population of Trechona sp. spiders, found in a quartizite cave in Diamantina, Minas Gerais, Brazil. The spiders and their retreats were marked, and this population was followed for 17 months. The population consisted of up to 100 individuals, comprising the worlds’ largest known cave-dwelling population of mygalomophs. The estimated population size (Jolly-Seber model) varied from 50.36 to 853.43, the latter considered much overestimated. We did not find individuals of Trechona sp. in the surrounding epigean areas. The number of spiders was higher in the entrance zone than in the other two zones (twilight and dark zones). We found that individuals at the entrance zone showed similar activity to a nocturnal spider, whereas the other two groups showed conspicuous differences from this pattern, spending longer periods without rest, on the sheet-web as a sit-and-wait predator.

An undescribed species of Banchinae from Chile in the Natural History Museum collections is described as Geraldus fittoni Broad, sp. nov. Four more specimens of Geraldus cambrensis have been found, from Chile and Argentina. The monophyly of Geraldus and of Philogalleria are supported.     

Terrestrial isopods from the Oued Laou basin,north-eastern Morocco (Crustacea: Oniscidea), with descriptions of two new genera and seven new species

Thirty-four species of terrestrial isopods (Crustacea: Oniscidea) from the Oued Laou basin, in the Rif area of north-eastern Morocco, are recorded. One genus (Paractenoscia) and seven species (Trichoniscus microphthalmus, Paractenoscia cavernicola, Bathytropa rifensis, Soteriscus gibbosus, S. laouensis, Porcellio pseudornatus, and Eluma praticola) are described as new. The genus Soteriscus, unavailable according to article 13.3 of the International Commission on Zoological Nomenclature (ICZN), is here revalidated by choosing S. gaditanus as type species. Six species (Graeconiscus thermophilus, Ctenoscia minima, Platyarthrus parisii, Porcellio humberti, Porcellio flavocinctus and Eluma caelata) have been fully illustrated to facilitate their identifications. Ctenoscia dorsalis Verhoeff is considered to be a junior synonym of C. minima Dollfus. Porcellio ornatus from southern Spain is also figured for comparison with P. pseudornatus sp. nov. The composition and origin of the oniscidean fauna of the Rif region is briefly discussed.

Description of Ghatiana,a new genus of freshwater crab,with two new species and a new species of Gubernatoriana (Crustacea: Decapoda: Brachyura: Gecarcinucidae) from the Western Ghat Mountains,India

A new genus of freshwater crab, Ghatiana, with two new species, Ghatiana aurantiaca and Ghatiana hyacintha, and a new species of Gubernatoriana Bott, 1970, are described from the Western Ghat Mountains in Maharashtra State, India. Ghatiana is most similar to Gubernatoriana by its wide, highly arched carapace and by the shape of the male abdomen. Nevertheless, the new genus can be distinguished from Gubernatoriana by the broadness of carapace, length of male abdomen, shape of sixth abdominal somite, length of telson and length of G1 terminal article. Ghatiana aurantiaca sp. nov. and G. hyacintha sp. nov. are distinguished by differences in body colour, carapace width, and G1 morphology, whereas Gubernatoriana triangulus sp. nov. is distinguished from two other known species [Gubernatoriana gubernatoris (Alcock, 1909) and Gubernatoriana pilosipes (Alcock, 1909)] by its triangular G1 subterminal segment and by its carapace morphology. Keys to the species of both the genera are provided.

Synopsis of the genus Pseudoperma Dillon and Dillon, 1946 (Coleoptera: Cerambycidae), with description of a new species

A synopsis of Pseudoperma is provided. This genus mainly differs from Onocephala and Stethoperma by the antennal tubercles well separated; antennae relatively short, in the female subequal to the body length; and scape and third antennomere subequal in length. Pseudoperma includes two species, P. chalcogramma (Bates, 1887) and P. patruelis (Breuning, 1940), both from Brazil; herein we describe one new species, Pseudoperma lingafelteri sp. nov. from Brazil (Rio de Janeiro). This species differs from its congeners mainly in having the frons and occiput covered with greyish pubescence, and the sides of the elytra with several interrupted or coalescent vittae. We provide new distribution data for Pseudoperma patruelis (Breuning, 1940) from Brazil, Minas Gerais, São Paulo and Santa Catarina, as well as illustrations and a key to the species of Pseudoperma.

Tedania (Porifera: Demospongiae: Poecilosclerida) from the Mexican Pacific with the description of two new species

Two new species of Tedania (Porifera: Demospongiae: Poecilosclerida) are described from the Mexican Pacific. Tedania (Tedania) tropicalis sp. nov. is an encrusting to massive sponge having ectosomal tylotes with microspined heads, choanosomal styles and onychaetes. Tedania (Tedania) fulvum sp. nov. is a thinly encrusting sponge having ectosomal tylotes with smooth heads, choanosomal styles and onychaetes. Tables for all the Tedania (subgenera Tedania and Tedaniopsis) and Trachytedania species described worldwide are included. We suggest that species of Tedania and Trachytedania bearing ectosomal diactinal spicules (excluding Tedania (Stylotedania)) can be separated in two main groups: those having choanosomal monactinal spicules and those with choanosomal diactinal spicules.

Some new and known species of Tylencholaimoidea (Nematoda: Dorylaimida) from Korea

A lineal “island” theory is proposed to account for the dispersal of marine/estuarine, supralittoral talitrid populations, both to and from isolated shore “islands” on continental and true oceanic islands. Evolution may occur following dispersal to shores that are contiguous with ecologically open habitats, inclusive of sub-tropical forest litter and caves. Specific hypotheses of the lineal “island” theory are therefore: the conventional wrack hypothesis 1 – direct from marine supralittoral wrack to subtropical forest litter; the driftwood hypothesis 2(a) – direct from marine supralittoral driftwood to subtropical forest litter; the driftwood hypothesis 2(b) – direct from the marine supralittoral driftwood to caves opening on a marine supralittoral; and the driftwood hypothesis 2(c) – direct from the marine supralittoral driftwood via caves to subtropical forest litter. Circumstantial evidence supporting each hypothesis is presented using the ecology and distribution data of the talitrid fauna of the northeast Atlantic islands, north of 25°N and south of 40°N, including the Canaries, Madeira and the Azores archipelagos. The currently known talitrid fauna of all these islands includes 15 species: seven endemic, subtropical landhoppers, two synanthropically introduced landhoppers, three wrack generalists, one sand-burrowing specialist, one specialist cavehopper, and one specialist driftwood hopper. Based on distributional data from the northeastern Atantic islands, specialist driftwood hoppers have a long distance dispersal capability, which makes them potential colonizers of distant oceanic islands. Talitrids provide an excellent model of dispersal and speciation, whose evolutionary pathways can be solved by modern genetic methods.
