Anterior Margin Of Carapace Research Articles

The genusGrosphusSimon, 1880 in South-Western Madagascar, with the description of a new species (Scorpiones, Buthidae)

ABSTRACT The South-Western portion of Madagascar appears to have one of the highest levels of scorpion diversity on the island. In this paper is presented an analysis of the known species of Grosphus Simon, 1880 from this region. Information on ecological aspects of the species is also given. A new species is also described from the region of Cap Sainte Marie, an area where micro-endemic patterns can be observed. The new species is characterized by a medium size with a total length of 50.3 mm. General coloration yellow to pale yellow without dark zones on body and appendages. Carapace yellow with an anterior reddish-orange zone, approximately forming an inverted triangle. Anterior margin of carapace strongly granular. Male pectines with 36–36 teeth. Fixed and movable fingers of pedipalps with 12–13 oblique rows of granules.

A new species of scorpion of the genus Neoscorpiops Vachon, 1980 (Scorpiones: Euscorpiidae) from India

A new species of scorpion of the genus Neoscorpiops Vachon, 1980 is described from Northern Maharashtra. Neoscorpiops maharashtraensis sp. nov. is a medium-sized scorpion species ranging from 36 to 42mm. Carapace, mesosoma and metasoma brown, legs and telson yellow; pedipalp in a shade of brown with carinae dark drown to black. Granulation on carapace coarse, with a few smooth patches; on mesosoma, which is restricted to the posterior half. Anterior margin of carapace with a moderately deep “U”-shaped emargination medially lacking elevated edges. Pectines well developed 7/7. Trichobothria on patella ventral 13–16. Pedipalp chela narrow and elongate in males, length-to-width ratio in males is 4.86–5.05.

A new species of the genus Centruroides Marx, 1890 (Scorpiones: Buthidae) from Guatemala

A new species of the genus Centruroides Marx, 1890 is described from northeastern Guatemala on basis to an adult male. By its general pattern and slight sexual dimorphism, the new species looks like C. flavopictus (Pocock, 1898), a larger species from Veracruz, Mexico, with higher pectinal tooth count (males: 21 to 24 teeth) and stronger subaculear tubercle. It also resembles Centruroides chamulaensis Hoffmann, 1932, from Chiapas, Mexico, a smaller species with small to obsolete subaculear tubercle, stronger metasomal carinae, pedipalp chelae narrower than patella, and anterior margin of carapace almost straight (V-shaped in the new species).

Review of the genus Plistobunus Pocock, 1903, with description of a new species from Hainan Island, China (Opiliones, Laniatores, Epedanidae)

The genus Plistobunus Pocock, 1903 and its type species Plistobunus rapax Pocock, 1903 are redescribed based on the type material deposited in the British Museum of Natural History (BMNH), London. In addition, a new Plistobunus species from Hainan Island is described and illustrated of Plistobunus columnarius sp. n. The new species is diagnosed by having a row of 12 setiferous tubercles on anterior margin of carapace, and the femur of pedipalpus ventrally with 13 setiferous tubercles in male.
