Comment: Orphnebius niger was described from an unspecified number of syntypes from “ Assam: Sudiya; Patkai Mountains” ( CAMERON 1939a). The sole syntype located in the collections at the BMNH, a female, is designated as the lectotype. In the original description of O. turensis , which is based on two females from “N India, Maghalaya [sic], 1 km E Tura 500–600 m, 25°30'N 90°14'E ”, PACE (2012b) compared the species with O. bryanti CAMERON, 1920 rather than with O. niger , probably because the latter was originally described in the genus Deroleptus . A comparison of the lectotype of O. niger with the holotype of O. turensis revealed that they are conspecific. Consequently, O. turensis is placed in synonymy with O. niger . The external and sexual characters of O. niger are illustrated in Figs 50–52 View Figs 40–53 , 296–298 View Figs 296–316 .
