Syndicus (s. str.) himalayanus Franz, 1975: 177 , fig. 7; Jałoszyński 2004: 23, figs 9M–O, 10A–C, 11D, 14D; Jałoszyński 2011: 26.

Material examined. 2 ♂♂, 8 ♀♀. labeled ‘ China: Yunnan, Yingjiang Hsien (盈江县), Nabang Town (那邦镇), 24°42′50.23″N, 97°35′07.58″E, nr. river, 300 m, 17.ii.2016, Jian-Yue Qiu & Hao Xu leg.’ GoogleMaps

Comments. Syndicus himalayanus ( Fig. 1 View FIGURE 1 A) shares with several congeners similar body size, body shape and body proportions, e.g., S. saketianus Jałoszyński , S. birmanicus Jałoszyński. Therefore , examination of the aedeagus ( Fig. 2 View FIGURE 2 A–C, F), especially structures of the endophallus (Fig. D–E) is necessary for an unambiguous identification. The large size of the endophallic proximal vesicle, the subrectangular, emarginated upper part of the central complex, and the elongate apical part of the endophallus with its apex forming a rounded structure allow for a certain identification ( Jałoszyński 2004: fig. 10A–C). Also, the shape of the spermatheca ( Fig. 3 View FIGURE 3 A–C) in S. himalayanus is extremely similar to that of S. saketianus , but the aedeagal structures of these two species are distinctly different. Here, the unique structure of bursa copulatrix of S. himalayanus is illustrated ( Fig. 3 View FIGURE 3 D–E), which has a triangular dorsal plate and a pair of lateral plates connected by a membranous structure.

Bionomics. The examined specimens were collected from underside of bark of a decaying log near a river in Nabang Town at an altitude of 300 m ( Fig. 5 View FIGURE 5 B–C).

Distribution. India: Assam and Meghalaya; Bhutan: Chukha; Nepal: Chitwan; China: Yunnan (new country record; Fig. 6 View FIGURE 6 ).
