A new monotypic wolf spider genus, Ovia gen. nov. is proposed to accommodate a misplaced species: Pardosa procurva Yu & Song, 1988. Ovia procurva comb. nov. is redescribed, illustrated and designated as the type species for the genus. The subfamily placement of the new genus is discussed and it is considered as a member of Lycosinae Sundevall, 1833 and possibly closely related to Alopecosa Simon, 1885. The presence of an apical process (spur) on the median apophysis is proposed as the putative synapomorphy of Ovia gen. nov. The possible sister-taxon relationship of Ovia gen. nov. with Alopecosa is discussed and evidence on the occurrence of sexual dimorphism and mating plug within the genus are presented. Ovia gen. nov. is assumed to be of Holarctic origin, from which it has migrated to the Indomalayan region. Additionally, a current distribution map for the genus is provided.

The taxonomic position and original description of Laophontina sensillata Wells & Rao, 1987 are reviewed based on specimens collected from the interstitial fauna of littoral coral sands of several islands of the Philippines and New Caledonia, and the species is designated as the type species of Fiersiphontina gen. nov. The new genus is proposed based on the total loss of sexual dimorphism in the P3 and P4 exopods, and the sexual dimorphism in P2 exopod. Fiersiphontina is highly adapted to the littoral interstitial habitat of coral sandy beaches, and is related to Laophontina Norman & T. Scott, 1905, Wellsiphontina Fiers, 1991 and Spiniferaphonte Gheerardyn & Fiers, 2007. The shared characteristics that indicate a strong affinity of Fiersiphontina to Spiniferaphonte are the robust, dorsally bent, and strongly sclerotised caudal seta V and the morphology of the genital field. The phylogenetic relationship of Spiniferaphonte and Fiersiphontina is also suggested by the analysis of the last ontogenetic phases of the species of the two genera. We re-describe here the adults of both sexes, describe the last three copepodid stages of Fiersiphontina sensillata (Wells & Rao, 1987) comb. nov., and provide notes on the biogeography of the four related genera, and on the ecology of Fiersiphontina and Spiniferaphonte.

A new pseudoscorpion genus, Tenebriochernes n. gen., with the type species T. concavus n. sp. is described from two caves in northern Colombia, where it inhabits the dark zone of caves. Two additional new species T. mohani n. sp. and T. pilosus n. sp., are described from conserved dry forest areas and buffer zones. Sexual dimorphism of the pedipalps is evident, particularly in the length of appendages and the width of the hand. The new genus shows affinities with the genus Neoallochernes Hoff, 1947. A taxonomic key, distribution map and ecological comments are given.

The sharpshooter genus Lebaziella is described and placed in the tribe Cicadellini. Two new species of Lebaziella gen.nov. are described and illustrated: the type-species L. renatae sp. nov. (Bahia State, Brazil) and L. viridis sp. nov. (Rio de Janeiro, São Paulo, and Paraná States, Brazil). Species belonging to the new genus can be distinguished from other genera of Cicadellini based on the following characters: (1) pronotum narrower than head with lateral margin parallel; (2) male pygofer without processes; (3) subgenital plate longer than pygofer with many microsetae distributed across its surface; (4) aedeagus with an unpaired apical process, and (5) paraphyses absent.

The genus Rhytidaspis Redtenbacher, 1891 is revised. The species R. fusca (Karny, 1911) is removed from the genus and combined with Haudrhytidaspis gen. nov. as type species, leaving only the type species R. picta Redtenbacher, 1891 in Rhytidaspis. The shapes of the male cerci and the complex structure of the male titillators in Rhytidaspis allows to differentiate between seven species and two subspecies of which six species and two subspecies are new to science: R. arfak sp. n., R. camela sp. n., R. genyem sp. n., R. nigropunctata sp. n., R. ornata sp. n., R. variata sp. n., R. variata brevis ssp. n., R. variata meja ssp. n.. A dichotomic key to species and a distribution map are provided. All records of Rhytidaspis known so far are from western New Guinea: Papua and Papua Barat (Indonesia) including Waigeo Island. Haudrhytidaspis fusca (Karny, 1911) had been described from New Guinea without precision.

(Philippines, Mindanao) and A. vitellinus sp. nov. (Indonesian New Guinea), is described. This new genus combines characters with a mosaic spread among other cillaeine genera. We present a wide comparison of genera among the subfamily Cillaeinae, making it possible to elaborate a detailed diagnosis of the new genus and trace some order in character patterns and propose a hypothesis on the relationship of this genus to other groups known from the Indo-Malayan and Australian Regions. A detailed diagnosis of the new genus and key to the new species are given. The Adocimus-complex of the related genera including Allenipeplus gen. nov., Adocimus Murray, 1864, Ithyphenes Murray, 1864, Platynema Ritsema, 1885 and probably Brittonema Kirejtshuk, 2011 is defined. Some notes on the taxonomy of the genera Liparopeplus Murray, 1864 and Xanthopeplus Fairmaire, 1880, stat. nov. are given. Additionally, designation of a lectotype for Liparopeplus colastoides Murray, 1864 is made.

ABSTRACT From a study of morphological and molecular datasets we determine that a species originally described as Sternarchogiton preto does not form a monophyletic group with the other valid species of Sternarchogiton including the type species, S. nattereri. Previously-published phylogenetic analyses indicate that this species is sister to a diverse clade comprised of six described apteronotid genera. We therefore place it into a new genus diagnosed by the presence of three cranial fontanels, first and second infraorbital bones independent (not fused), the absence of an ascending process on the endopterygoid, and dark brown to black pigments over the body surface and fins membranes. We additionally provide a redescription of this enigmatic species with an emphasis on its osteology, and provide the first documentation of secondary sexual dimorphism in this species.

A New Species

Both sexes of a new species of Noodtorthopsyllus Lang, 1965 (Harpacticoida, Cristacoxidae) from a sandy beach in São Paulo State (Brazil) are described using light and scanning electron microscopy. Noodtorthopsyllus tageae sp. nov. displays a mosaic of characters drawn from both Noodtorthopsyllus and Cristacoxa Huys, 1990, blurring the boundaries between both genera. Consequently, Cristacoxa, the type genus of the nominal family-group taxon Cristacoxidae Huys, 1990, is relegated to a junior subjective synonym of Noodtorthopsyllus, and its type species is transferred to the latter as N. petkovskii (Huys, 1990) comb. nov. A new genus Acuticoxa is proposed to accommodate A. ubatubaensis sp. nov. (type species), collected on the northern continental shelf of São Paulo State, and A. biarticulata sp. nov., previously identified as Laophontisochra sp., from the Northern Magellan Straits. Amended diagnoses are provided for Noodtorthopsyllus and Laophontisochra. Autapomorphies supporting the monophyly of the Cristacoxidae are re-evaluated, including new data on P3 endopod sexual dimorphism and caudal ramus development. It is concluded that a recently published hypothesis of a deeply rooted split of the family into two highly divergent lineages cannot be supported. Consequently, both Laophontisochra and Acuticoxa gen. nov. are removed from the Cristacoxidae and tentatively assigned to the Nannopodidae (ex Huntemanniidae), forming a clade with three other genera displaying coxal modifications on leg 1 (Rosacletodes Wells, 1985; Huntemannia Poppe, 1884; and an as yet undescribed genus from Brazil). Based on the sexual dimorphism of the P4 endopod, we propose to transfer Metahuntemannia Smirnov, 1946 and Pottekia Huys, 2009 from the Nannopodidae to the Canthocamptidae (subfamily Hemimesochrinae) where they are probably most closely related to Psammocamptus Mielke, 1975; Bathycamptus Huys & Thistle, 1989; Perucamptus Huys & Thistle, 1989; and Isthmiocaris George & Schminke, 2003. An identification key to the genera of the Nannopodidae is presented.

We erect a new genus, Esophyllas n. gen., to place two litter dwelling species of erigonine spiders from southern Califor-nia the type species, E. vetteri n. sp. and E. synankylis n. sp. A detailed genus diagnosis is presented as well as compre-hensive morphological descriptions, artist illustrations, and SEM images for each species. We also provide data on habitataffinities, phenology, and distribution, including a distribution map figure. For tentative phylogenetic placement both spe-cies were scored for the characters in the data matrix of Miller & Hormiga (2004) and subsequently entered into the ex-panded matrix of Frick et al. (2010). The analysis places Esophyllas n. gen. within the “distal erigonines” as sister toScirites Bishop and Crosby in a polytomy with Tapinocyba Simon 1884 and Abacoproeces (L. Koch). Data from morpho-logical comparisons with taxa not included in the expanded matrix do not strongly support these relationships but insteadsuggest that Esophyllas n. gen. is more closely related to Phlattothrata parva (Kulczyn’ski 1926). However, in light ofthe extent of character divergence from the above genera we contend that the true sister group to Esophyllas n. gen. either has not yet been described or is among the vast number of phylogenetically untested taxa.
