A revision of the mole cricket genus Scapteriscus with the description of a morphologically similar new genus (Orthoptera : Gryllotalpidae : Scapteriscinae) [Review]

摘要

The mole cricket genus Scapteriscus Scudder, 1869 is revised to include 21 species, 9 of which are described herein as new: costaricensis, didactyloides, ecuadorensis, grossi, macrocellus,peruvianus, quadripunctatus, saileri, and tibiodentalis. Two species, S. tenuis Scudder 1869 and S. didactyloides Nickle new species, each have several geographical variants which may prove to be distinct species. Two species, S. leptodactylus Chopard, 1928 and S. siangensis Tandon and Shishodia 1972, described from India and Pakistan, are removed from Scapteriscus and placed in a new genus, described herein as Indioscaptor Nickle. Species of Scapteriscus are defined using both traditional morphological characters and other methods of species recognition, including analyses of morphometrics and cuticular hydrocarbons.
