First records of Leptopezella Sinclair & Cumming (Diptera: Hybotidae: Ocydromiinae) from Brazil

Leptopezella Sinclair & Cumming, 2007 is a small genus of Ocydromiinae characterized by the absence of cell dm (Fig. 3) and presence of ventral spine-like setae on the hind first tarsomere (Fig. 2). It was first mentioned as “undescribed genus A” in the key of Sinclair & Cumming (2000) and later described including four species: L. anatolica Sinclair & Cumming, 2007, L. perata Sinclair & Cumming, 2007 and L. spinosa Sinclair & Cumming, 2007 from Australia and L. masneri Sinclair & Cumming, 2007 from Bolivia (Sinclair & Cumming 2007). In South America the genus has been recorded so far from Bolivia and Argentina (Sinclair & Cumming 2000, 2007). In the present study we record the genus occurring for the first time in several administrative states from Brazil.

Redescription of the little known hermit crab, Clibanarius clibanarius (Herbst, 1791) (Decapoda: Anomura: Diogenidae), based on material from southern India and type material

A little known littoral hermit crab, Clibanarius clibanarius (Herbst, 1791), is redescribed on the basis of material from southern India, supplemented by the photographs of the type material. The species appears closest to C. infraspinatus Hilgendorf, 1869, but the absence of a prominent ventral spine or protuberance on the cheliped meri immediately distinguishes C. clibanarius from C. infraspinatus. Although the species has been reported from wide areas in the Indo-West Pacific, records outside of India still needs to be verified.

An atypical new species of Bothryonopa (Coleoptera, Chrysomelidae, Cassidinae, Bothryonopini) from south India

Bothryonopa sahyadrica n. sp., an atypical new species of the genus from southern Western Ghats biodiversity hot-spot in India is described and illustrated. The new species lacks ventral spine on all femora, in contrast to majority of the members of the genus, including the type species. Pronotum is anteriorly distinctly narrower than posteriorly with evenly curved anterolateral corners in the new species, while pronotum in the typical species is widest medially and not distinctly narrowed anteriorly. Host plant of B. sahyadrica n. sp. is Calamus gamblei Becc. & Hook. f. (Arecaceae).

New species of Tomocerus (Entomobryomorpha, Tomoceridae) with remarkable form of mucronal dorsal lamella

Two new species of Tomocerus are described from Shaanxi and Gansu Provinces, China. Tomocerus nuwa sp. nov. and Tomocerus fuxi sp. nov. are similar to Tomocerus violaceus, Tomocerina yiliensis and Tomocerina tianshanensis mainly in the habitus and the basal formula of dental spines, but are different from the laters and most other known species of Tomocerinae mainly in the characteristic apical structure of mucronal dorsal lamella. Besides, these two species are similar to each other in the presence of only one typical bothriotrichum on Th. II, the number and position of ventral spine-like chaetae on tibiotarsi and the arrangement of dental spines on the basal subsegment of dens, but are different mainly in the chaetotaxy, the manubrial pseudopores and corner chaeta, and the arrangement of dental spines on the middle subsegment of dens.

Macrostylis cerritus sp. nov., a new species of Macrostylidae (Isopoda: Asellota) from the Weddell Sea, Southern Ocean

Macrostylis cerritus sp. nov. (Macrostylidae) is described from the Weddell Sea, Antarctica, at a depth of 2149 m. The new species differs from other species of Macrostylis due to the incisor with 4 cusps; the strongly hook-shaped ischium of pereopod 3; pereopod 4 being greatly reduced and juvenile in appearance; the operculum bearing a ventral spine-like seta; and the absence of pleopod 5. This species is the fourth deep-sea macrostylid identified from the Southern Ocean, and is one more species described from the specimens of ANDEEP I–III expeditions.

A new species, Apseudes larseni (Crustacea: Tanaidacea),from the marine waters of New Zealand

Apseudes larseni, new species, is described from the marine waters of New Zealand in depths of 108–1357 m. The new species belongs to a group of species characterized by the presence of lateral spines on both the carapace and pereonites. Apseudes larseni can be distinguished from all but one of these species, A. graciloides, by having two pairs of lateral spines on the carapace. Apseudes larseni also differs from A. graciloides by (1) the lateral spines of pereonite 1 having a different placement, (2) pereonite 2 having four pairs of lateral spines, as opposed to one pair in A. graciloides, (3) the cheliped with merus having a ventral spine (absent in A. graciloides) and a distinctly shorter and stouter carpus, and (4) pereopod 1 with basis lacking ventral spines (present in A. graciloides). The morphological similarity of the two sexes, especially in the similar cheliped and the apparent presence of a reduced genital cone on some female specimens, suggest the possibility that Apseudes larseni may be hermaphroditic.

Stephanostomum talakitok n. sp. (Digenea: Acanthocolpidae) from the golden trevalley, Gnathanodon speciosus (Perciformes: Carangidae), from Ningaloo Reef, Western Australia

A new species, Stephanostomum talakitok n. sp., is described from the golden trevally Gnathanodon speciosus, Ningaloo Reef, Western Australia. It has 36 (34ñ40) circum-oral spines and the vitellarium reaches to no less than 10ñ17% of the hindbody length from the ventral sucker. It differs from other species of Stephanostomum with these characteristics by combinations of the gradual diminution of the circum-oral spine size to a small mid-ventral spine, the contiguous gonads with no intervening vitelline follicles, the sucker-ratio and various other ratios, including the distance between the ventral sucker and the ovary and the distance the cirrus-sac reaches into the hindbody, both as a proportion of body length.

Acanthocopinae (Crustacea: Isopoda: Munnopsididae) from the Southern Ocean deep sea with the description of Acanthocope eleganta sp. nov.

Acanthocope eleganta sp. nov. is described from the abyssal Southern Ocean near the Southern Ocean Peninsula. The new species differs from others in the following: a slender dorsomedial spine on the pleon anteriorly, a pair of short dorsal spines and long ventral spine on each of pereonites 5 and 6; uropods half as long as the terminal spine of the pleotelson and with a minute exopod. A. annulatus Menzies, 1962 is redescribed; A. galatheae Wolff, 1962, previously known only from the Gulf of Panama and from Angola Basin, is recorded from the northwest Weddell Sea.
