Themus (Haplothemus) weishanensis Kopetz, 2016: 253  , Figs 12View FIGURES7–15, 35.

Other material examined. China, Yunnan: one male, one female ( IZASAbout IZAS)  : Yunnan, Lijiang, Lameirong , 2300m, 10.VIII.1984, leg. S.Y. Wang  ; one female ( IZASAbout IZAS), same locality and date, leg. R.Q. Wang. 

Distribution. China (Yunnan).

Supplementary description. Male ( Fig. 5View FIGURES 1–6). Aedeagus (Figs 19‒21): ventral process of each paramere evenly wide but narrowed apically at apical one-third portion, acute and slightly hooked at apex, longitudinally depressed along the whole length, moderately bent inwards in ventral view; conjoint dorsal plate of parameres distinctly shorter than ventral processes, with lateral margins abruptly converging apically, apical margin moderately widely and sub-triangularly emarginated in middle, latero-apical angles figure-like in dorsal view; laterophyses compressed and slightly longer than conjoint dorsal plate, separated on both sides of median lobe and nearly parallel to each other, acute and slightly hooked at apices, which pointed dorsally.

Female. Similar to male, but eyes less protruding, antennae slightly shorter, almost extending to basal twofifths length of elytra, antennomeres III slightly shorter than II, pronotum with lateral margins nearly parallel, slightly convex on postero-lateral parts of disc.

Abdominal sternite VIII ( Fig. 33View FIGURES 30–34) narrowly emarginated in middle of posterior margin, which is nearly truncated at apex of lateral portion beside middle emargination.

Internal reproductive organ of genitalia ( Fig. 28View FIGURES25–29): vagina stout, with diverticulum and spermatheca situated at apex, median oviduct at basal one-third part of ventral side; diverticulum slightly long tube-shaped, distinctly shorter than vagina, evenly thick in the whole length, about 4.0 times as long as wide, rounded at apex; spermatheca slightly long sac-shaped, slightly expanded apically and rounded at apex, which is slightly longer than diverticulum, and provided with a moderately long and thin accessory gland at base; diverticulum and spermatheca surrounded with a strongly sclerotized ring at base, which is confluent in middle and extending to median oviduct on ventral side, the opening of spermatheca arising from middle of the sclerotized ring on dorsal side.

Body length (both sexes): 17.0‒20.0 mm; width: 4.0‒5.0 mm.

Remarks. The female of T. (H.) weishanensis Kopetz, 2016  is discovered for the first time and it makes us to provide some supplementary information for this species. Besides, the aedeagus was provided with the photo of dorsal side by Kopetz (2016), here it is illustrated and described in ventral, dorsal and lateral views.
