The new Australian wolf spider genus Tuberculosa is revised, with T. harveyi, sp. nov. from the Northern Territory as type species. The genus includes a further three species from northern Queensland: T. austini, sp. nov., T. hoggi (Framenau & Vink, 2001), comb. nov. and T. monteithi, sp. nov. The genus is defined by a unique sexual dimorphism: males carry modified tubercular setae on the ventral side of the third coxae, which are here compared to the knobbed setae that can be found on the ventral surface of the abdomen in Hygrolycosa rubrofasciata Ohlert, 1865 and Passiena torbjoerni Lehtinen, 2005 from two different lycosid subfamilies. Based on the structure of the male pedipalp, Tuberculosa belongs to the subfamily Lycosinae sensu Dondale (1986) with close affinities to Venatrix Roewer, 1960, because males of both genera have a tubercle on the outer edges of their fangs and the cymbium tip carries claw-like macrosetae. A cladistic analysis of all four Tuberculosa species, based on 12 morphological characters and with Venatrix konei (Berland, 1924) as outgroup, revealed a topology with T. austini and T. harveyi as sister-species in the most derived clade (V. konei (T. monteithi (T. hoggi (T. harveyi, T. austini))). The distribution of Tuberculosa in the tropical north of Australia supports an origin of the genus, as well as its putative sister-genus Venatrix, in the Palaearctic region, in contrast to all other Australian Lycosinae, which appear to be of Gondwanan origin.

A New Species

A cladistic analysis based on 274 morphological characters was performed including the 13 previously recognized speciesof the scale mite genus Hirstiella, 2 new species, 5 species in closely related genera, and 3 more distant out-group species.An analysis based on 148 informative characters resulted in one most parsimonious tree (L = 400, CI = 0.57 and RI =0.79). According to this, the genus Hirstiella in its current concept is a polyphyletic taxon whose member species belongto three different clades. The first lineage (Bremer support and jackknife values 2 and 78%) includes the type species H.trombidiiformis and seven additional species of Hirstiella that are parasites on iguanian lizards. The genus Geckobiella isincluded in this lineage, and the latter taxon name has priority over Hirstiella; therefore, the genus Hirstiella is considereda synonym of Geckobiella and no longer valid. For the second lineage (Bremer support and jackknife values of 2 and 73%)we propose the name Bertrandiella gen. nov.; it includes H. tenuipes, H. otophila, H. jimenezi and Bertrandiella chame-laensis sp. nov. The third lineage, and sister taxon of Bertrandiella, is a clade comprising Pimeliaphilus and the speciesH. sharifi and H. insignis. The latter taxa are transferred back to Pimeliaphilus (Bremer support and jackknife values >4and 100%). Updated diagnoses are provided for the genera Geckobiella sensu nov. (including a new species Geckobielladonnae sp. nov.) and Bertrandiella gen. nov., and for all their species, as well as for the genera Pimeliaphilus sensu nov.and Tequisistlana, based on the results of the phylogenetic analyses. The analyses support the hypothesis that lizards arethe ancestral hosts for Pterygosomatidae; associations with arthropods (in Pimeliaphilus) appear to be secondary, the result of host switching from lizards.

Species Groups

Simulium (Gomphostilbia) Enderlein, the third largest (206 named species included) in the genus Simulium Latreille s. l., is one of the two most abundant and diverse subgenera in the Oriental Region. To provide a classification scheme to facilitate morphological identification of the species within this subgenus, its diagnostic characters are redefined, and nine known species-groups within it are reviewed. Based on putative lineages explored by using certain adult morphological characters, seven more species-groups are proposed: asakoae, darjeelingense, epistum, gombakense, heldsbachense, hemicyclium and palauense species-groups, while the trirugosum species-group is merged in the varicorne species-group. Subgroups are also introduced to represent apparently different lineages within certain species-groups based on certain pupal morphological characters: two in the banauense species-group, seven in the batoense species-group redefined, four in the ceylonicum species-group redefined, four in the epistum species-group, two in the hemicyclium species-group, two in the sherwoodi species-group and four in the varicorne species-group redefined. A new checklist of species of the subgenus Gomphostilbia, and a key to all 15 species-groups within it are provided. The eastward expansion of the geographical distribution of the subgenus Gomphostilbia is inferred on the basis of the more frequent occurrence of apomorphic characters of certain adult and pupal morphological features in insular species-groups than in continental species-groups. A preliminary attempt using a cladistic analysis of morphological characters shows that among 10 subgenera examined, Gomphostilbia has a sister-taxon relationship with the Australasian subgenus Morops Enderlein, and this clade, together with the Central-Western Pacific subgenus Inseliellum Rubtsov, is positioned closest to the most derived clade formed by Daviesellum Takaoka & Adler and Simulium Latreille s. str.

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 assassin bugs of the genus Ptilocerus Gray, 1831 (Hemiptera: Heteroptera: Reduviidae: Holoptilinae) occurring in the Australian Region are reviewed for the first time, resulting in the description of two new species, viz., P. spangenbergi sp. nov. (Queensland and Northern Territory, Australia) and P. papuensis sp. nov. (Papua New Guinea). The latter species differs from P. fuscus Gray, 1831 (the type-species of genus Ptilocerus) in a couple of major external morphological characters, hence its tentative placement in the genus Ptilocerus is discussed. A key for the separation of the two new species is provided.

A New Species

A new species of priapiumfish, Phallostethus cuulong, is described based on nine specimens collected from the Vietnam-ese Mekong. This is the third species of the genus, following the type species P. dunckeri (from Malay peninsula) and P.lehi (from northwestern Borneo), and distinguished from them by having: seven serrae on the second ctenactinium in adultmales (vs. five in P. dunckeri and eight in P. lehi); 25–26 caudal vertebrae (vs. 27 in P. dunckeri and 28 in P. lehi); approx-imately 5–19 teeth on paradentary (vs. 15–20 and 28 or more in P. dunckeri and P. lehi, respectively). All six examinedmales are dextral (vs. one and two known males are sinistral and dextral respectively in P. dunckeri, and all four knowmales are sinistral in P. lehi). Sexual dimorphism is also found in the number of precaudal vertebrae, i.e., 13–14 in males and 11–12 in females (vs. sexual dimorphism is not found in number of precaudal vertebrae of P. dunckeri and P. lehi).

Dilocarcinus Pagei

The juvenile development of the freshwater crab Dilocarcinus pagei Stimpson, 1861 was studied under laboratory conditions, focusing on setae morphology. The ovigerous females were collected manually associated with water hyacinth at the Municipal Dam of São José do Rio Preto (São Paulo, Brazil). The specimens were raised in the laboratory under constant aeration, photoperiod (12 : 12 h) and temperature (27 ± 1°C). Twelve juvenile stages were obtained with descriptions of the main morphological characters that allow their identification are presented. Fourteen types of setae were discovered: dentate, denticulate, serrulate, papposerrate, cuspidate, plumose, plumodenticulate, plumoserrulate, simple, pappose, brush, curved, nail and setules. The greatest diversity of setae was found on the mouth appendages, especially the maxillule. The gill ontogeny and sexual dimorphism becomes apparent from the second juvenile stage onwards. At the third juvenile stage, the carapace begins to exhibit a wider shape, becoming similar to that of the adults.

Initial Event

The Australian genus Theprisa Moore, 1963, is taxonomically revised to comprise five species, two newly described: Theprisa darlingtoni Liebherr & Porch, sp. nov. of Tasmania, and Theprisa otway Liebherr, Porch & Maddison, sp. nov. from the Otway Ranges, Victoria. Two previously described species, T. australis (Castelnau) and T. montana (Castelnau), are distributed in the mountains of Victoria. The third previously described species, T. convexa (Sloane) is found in Tasmania. A lectotype is designated for T. convexa because the various syntypes are ambiguously labelled. Cladistic analysis based on morphological characters establishes monophyly of Theprisa relative to the Australian genera Sitaphe Moore and Spherita Liebherr. This and a second clade of Australian genera (Pterogmus Sloane, Thayerella Baehr, and Neonomius Moore) do not form a natural group, but are cladistically interdigitated among two monophyletic New Zealand lineages (Tarastethus Sharp, and Trichopsida Larochelle and Larivière) suggesting substantial trans-Tasman diversification among these groups. Hypothesized relationships within Theprisa are consistent with two bouts of speciation involving the Bass Strait; an initial event establishing T. convexa as adelphotaxon to the other four species, and a more recent event establishing the sister species T. darlingtoni and T. montana. Geographic restriction of T. otway to the Otway Ranges is paralleled by Otway endemics in several other carabid beetle genera, as well as by endemics in numerous other terrestrial arthropod taxa. Whereas these numerous Otway endemics support the distinctive nature of the Otway Range fauna, their biogeographic relationships are extremely varied, illustrating that the Otways have accrued their distinctive biodiversity via various means.

The Status

The historical status of the family Platypodidae is reviewed and the family is revised. Results of a cladistic analysis based on 35 terminal taxa and 80 adult morphological characters show that the current placement of Platypodidae makes the subfamily Scolytinae paraphyletic. Moreover, several important genera included in Scolytinae are shown to be members of Cossoninae (i.e. the placement of Protoplatypus Wood and Phylloplatypus Kato in Cossoninae is confirmed). Based on these results, the status of Platypodidae as a family and subfamily is rejected, Scolytinae thereby becoming a monophyletic taxon. Araucarius groups in Scolytinae instead of Cossoninae in the analysis on a single step only, but it is suggested that it be retained in Cossoninae until this subfamily is submitted to a similar phylogenetic study. Three genera and four species of Cossoninae are described as new: Dobionus Kuschel, gen. nov.: type species D. araucarinus Kuschel, sp. nov. (with the inclusion of D. brachyrhinus (Montrouzier)); Coptonus Kuschel, gen. nov.: type species C. fijianus Kuschel, sp. nov. (with the inclusion of C. papuanus Kuschel, sp. nov.) and Dissostomus Kuschel, gen. nov.: type species D. hornabrooki Kuschel, sp. nov.

A revision of the genus Leydigia Kurz, 1875 (Anomopoda, Cladocera, Branchiopoda) is presented. The list of all species-group nominal taxa consists of 34 published and 3 unpublished names. Of these, 12 species are accepted as valid: (1) Leydigia (Leydigia) leydigi (Schödler, 1863); (2) L. (L.) louisi Jenkin, 1934 with two subspecies L. louisi louisi Jenkin, 1934 and L. louisi mexicana Kotov, Elías-Gutiérrez et Nieto, 2003; (3) Leydigia (Neoleydigia) propinqua Sars, 1903; (4) L. (N.) australis Sars, 1885; (5) L. (N.) microps Sars, 1916; (6) L. (N.) sp. nov. from 'L. acanthocercoides' in Alonso, 1996; (7) L. (N.). macrodonta Sars, 1916; (8) L. (N.) acanthocercoides (Fischer, 1854); (9) L. (N.). laevis Gurney, 1927; (10) L. (N.) cf. ipojucae Brehm, 1939; (11) L. (N.) ciliata Gauthier, 1939; (12) L. (N.) cf. striata Birabén, 1939. Lectotypes are selected for 3, 5, 7, and 9. Exact identification of 10 and 12 is not possible without examination of material from type localities and neotype selection. As confirmed by examination of authors' type material, some taxa (Leydigia africana Gurney, 1904 and Leydigia ankammaraoi Prasad, Santa Kumari et Bose, 1985) prove to be junior synonyms of previously described species; species 8-12 form a compact acanthocercoides-group, with fine differences among members. A cladistic analysis for 13 studied taxa and 18 morphological characters resulted in four most-parsimonious trees (TL = 32; CI = 0.78), which differ only in the grouping of members of the L. acanthocercoides-group. A slightly polytomic strict consensus tree (the 50% majority rule bootstrap simulation led to a tree of similar topology to the contree), as well as some 'orthodox' ideas on the evolution of the genus (not contradicting each other), are used to subdivide the genus into two subgenera, Leydigia (Leydigia) Kurz, 1875 and Leydigia (Neoleydigia) subgen. nov. L. (N.) acanthocercoides is the type species of the latter. A key for the identification of well-known species of Leydigia is provided. The level of description of representatives of the genus Leydigia in different continents is estimated, and perspectives for further investigations are outlined.
