Scorpio basraensis sp. n. from southern Iraq (Scorpiones: Scorpionidae)

  Scorpio basraensis sp. n. from southern Iraq (Scorpiones: Scorpionidae) Abstract A new scorpion species, Scorpio basraensis sp. n. , is described and illustrated from Basra Province, southern Iraq. Scorpio basraensis sp. n. is compared with all known species of the genus Scorpio Linnaeus, 1758 occurring in countries surrounding Iraq. The new species can be distinguished by the circular genital operculum in males and the cordiform genital operculum in females (not posteriorly elongated), a densely hirsute body, appendages and metasoma, a distinctly elongated telson vesicle, discrete granules on the external surface of the chela manus that are not flattened, and pectinal tooth counts of 11–13 in males and 9–11 in females. With the description of this species, the number of scorpion species known from Iraq increases to 22, whereas the number of recognized species in the genus Scorpio reaches 33.

Abstract

Herein, we redescribe Neostenotarsus guianensis (Caporiacco, 1954) nearly seven decades after its original description. In the original description of Neostenotarsus scissistylus Tesmoingt & Schmidt, 2002, we found characters incongruent with N. guianensis, namely, the purported presence of serration on the prolateral keels of the palpal bulb; a narrower apical third of the embolus; the absence of a patch of bristles on the retrolateral face of the palpal tibia and of a baso-retrolateral protuberance on metatarsus I; and a shorter and more apically situated megaspine on the retrolateral branch of the tibial apophyses. The characters from its original description are discussed. Nscissistylus stat. rev. has been revalidated until such time as the type material, or topotypic material, can be examined by future workers.
