Diagnosis.

Distinguishable from superficially similar specimens of Tillicera sensibilis by body stouter (length to width ratio of elytra: male about 2.04, female 2.11), length to width ratio of terminal antennomere of both sexes evidently below 1.5, metaepisternum black, at least the lateral part of metasternum black, pubescence on metaepisternum and metasternum yellow and almost as thick as golden decumbent setae on elytra, dorsal sinus of tegmen triangular, ventral sinus digitiform, and dorsal margin of phallus with large denticles extending from anterior half to posterior sclerotized area; and distinguishable from Tillicera wenii by pattern-forming setae on elytra more gold colored, metaepisternum black, at least the lateral part of metasternum black, pubescence on metaepisternum and metasternum yellow and almost as thick as golden decumbent setae on elytra, meta-P1 absent and meta-P2 just vestigeal, pit-like sensilla of male terminal antennomere larger and shallower (distinct in magnification 100 × before treated with KOH solution) (Figs 29, 32), paramere not pointed, dorsal sinus triangular, ventral sinus digitiform.

Supplemental description.

Elytra: Length to width ratio: male about 2.04, female about 2.11.

Terminal antennomere: Length to width ratio of both sexes below 1.5; male with a shallow pit-like sensillum present at basal third, diameter 0.08 mm (clearly distinct in magnification 100 × before and after treated with KOH solution) (Figs 29, 32).

Male terminalia: Ratio of length of paramere to whole tegmen 0.17: 1, paramere thumb-like in dorsal view, dorsal sinus triangular, ventral sinus digitiform (Figs 5-6); phallic plate with large denticles along dorsal margin and fine granular structures on posterior sclerotized area (denticles extending from anterior half to posterior sclerotized area; number of denticles can vary between left and right phallic plate and between individuals but whole length of denticles is consistent) (Figs 7-8, 12); phallic ventral membrane with one line of file-like structures on each side (Fig. 7); spicular fork (Fig. 9); tergum VIII (Fig. 10), sternum VIII (Fig. 11).

Female reproductive organs: Vagina swollen, base of bursa copulatrix narrower than posterior end of vagina; swollen zone between vagina and spermathecal duct larger than that in Tillicera sensibilis ; length of bursa copulatrix three times as long as spermatheca; spermathecal gland attached to basal fourth of spermatheca (Figs 36, 37); both dorsal and ventral lamina of ovipositor undivided (Figs 34, 35).

Distribution.

China: Yunnan (new record), Guangxi (new record), Hainan (new record), Xizhang; Thailand; Laos; Vietnam.

Material examined.

Lectotype designated here: female, "Type [printed]/Type [handwritten by Pic]/Tonkin, Chapa, 27.VI.1918, Jeanvoine/ Pseudoclerops auratofasciatus n. sp. [handwritten by Pic]/ Tillicera auratofasciatus Pic/Museum Paris, Coll. M. Pic/HOLOTYPE Tillicera auratofasciata (Pic, 1927), Revision 2009, Gerstmeier & Bernhard" (MNHN).

Remarks.

The name-bearing type was not fixed in the original publication and there was no imply how many type series was. For the purpose to fix the name-bearing type, the lectotype is designated here, which is the same specimen noted as "holotype" in Gerstmeier & Bernhard (2010).
