A review of the orientalis group of the Otostigmus subgenus Otostigmus Porat, 1876 (Chilopoda: Scolopendromorpha: Scolopendridae).

Abstract

The Otostigmus subgenus Otostigmus, which currently comprises 58 species, was subdivided by Lewis (2010a) into nine species groups based on Attems' (1930a) monograph. The orientalis group comprising 19 species and two subspecies is the subject of this paper. In most cases, the type material is redescribed and variation discussed. The following species are valid: O. ateles Chamberlin, 1920, O. australianus Attems, 1930, O. brevidentatus Verhoeff, 1937, O. foveolatus Verhoeff, 1937, O. kashmiranus Lewis, 1992, O. metallicus Haase, 1887, O. multidens multidens Haase, 1887, O. oatesi Kraepelin, 1903, O. orientalis Porat, 1876, O. ruficeps Pocock, 1890, and O. striolatus Verhoeff, 1937. O. seychellarum Attems, 1900, is reinstated as a valid species and O. niasensis Silvestri, 1895, and O. sucki Krae-pelin, 1903 which may be O. metallicus are regarded as valid pro tem. O. greggi Chamberlin, 1944, is a junior subjective synonym of O. astenus (Kohlrausch, 1881), and O. loriae Silvestri, 1895, and O. multidens carens Attems, 1938, junior subjective synonyms of O. multidens. O. loriae nordicus Schileyko, 1995, becomes O. multidens nordicus comb. nov. O. nemorensis Silvestri, 1895, O. poonamae Khanna & Tripathi, 1986, and O. telus Chamberlin, 1939, are nomina dubia. A key to the species is provided.
