(Figs 437–439)

Tetrabothrus indicus CAMERON, 1939a: 459 f.

Type material examined: Lectotype ♂ [dissected prior to present study], present designation: “818 / Samsingh 1800’, Kalimpong, Bengal . XII.1933, Balwant Singh. / In soil under elephant dung. / R.R.D. 638 / Tetrabothrus indicus Cam, Type / M.Cameron. Bequest. B.M. 1955-147 / Tetrabothrus indicus Cam., det. R. Pace 1989, Holotypus / Lectotypus ♂ Tetrabothrus indicus Cameron, desig. V. Assing 2015” (BMNH).

Material examined: Sri Lanka: 2♂♂, S Wellawaya, 300 m, 25.I.1970, leg. Mussard, Besuchet & Löbl (MHNG, cAss) .

Comment: The original description is based on an unspecified number of syntypes from “Bengal: Kalimpong: Samsingh, alt. 1800 feet. On soil under elephant dung” (CAMERON 1939a). The sole syntype in the Cameron collection is designated as the lectotype. The two males from Sri Lanka are distinguished from the holotype by the slightly different shape of the crista apicalis of the aedeagus and by slightly darker coloration. However, since no additional distinguishing characters were found, these differences are attributed to intraspecific variation.

Confirmed records of this species are known only from West Bengal (type locality) and from Sri Lanka. The record from Thailand by PACE (2012c) most likely refers to T. inflexus .
