The new species is very similar to H . bizonatus , the previously only known species in the genus; their differences: in H . bizonatus , dorsal surface of A1 as dark as other antennomeres, ventral side of metafemora black, tibiae black, red area at extreme base of elytra not reaching anterior yellow band; short decumbent setae on pronotal arch black; only setal alveoli in pronotal disc raised, while those setal alveoli around and outside lateral pits not raised and thus only pronotal disc granulose; the two protuberances along lateral margin of pronotum proper quite distinct, lateral pit seems deeper; A10 about 1.5 times as long as its width; inner margin of dorsal sinus of tegmen sinuate ( Fig. 5 ); apex of phallus narrow; spiculum on phallus ventral apex about twice length as apical sclerotized region ( Figs. 14, 18 ), that on phallus dorsal apex a little longer than or shorter than apical sclerotized region ( Figs. 15, 19 ); the sclerotized region along midline of phallic plate very slender; sternite VIII with posterior margin strongly notched in middle ( Fig. 11 ); in H. tubericollis n. sp. dorsal surface of A1 distinctly lighter than other antennomeres, brown to red, all parts of legs brownish red, red area at extreme base of elytra continued down along suture to anterior band; short decumbent setae on pronotal arch white; all setal alveoli raised and thus the whole pronotum granulose; the two protuberances along lateral margin of pronotum proper less distinct, and lateral pit seems shallower; A10 about 2.0 times as long as its width; inner margin of dorsal sinus of tegmen only simply curved ( Fig. 20 ); apex of phallus broader; spiculum on both ventral and dorsal sides quite short, about half length as the apical sclerotized region ( Figs. 25, 26, 28 ); the sclerotized region along midline of phallic plate broader ( Figs. 7, 8 , 21, 27 ); sternite VIII with posterior margin shallowly concaved ( Fig. 24 ). Description. Size : length 6.3–7.3 mm , width 2.3–2.8 mm . Color : Head with dorsal surface black, labrum, labium and maxilla yellowish or brownish red; antennae black, basal two or three segments somewhat paler, A1 yellowish red. Pronotum and scutellum red. Elytra black with two yellow bands (integument yellow, covered with golden decumbent setae), anterior band just before middle, posterior band subapical; extreme elytral base, including humeral area, red, red region continued down along suture to anterior band;. Legs brownish red. Ventral surface of head, prosternum, mesosternum and metasternum yellowish to brownish red, metepisternum and abdomen black. Head : Length of A6–10 twice as long as each width. Prothorax : PL/PW = 0.87–0.90, lateral pit distinct, the two protuberances in lateral marginal areas indistinct. Short decumbent setae on pronotal arch and pronotum proper white, dense; long erect setae on pronotal arch and pronotum proper dark brown, several long erect setae near undersurface of pronotum proper yellow. Alveoli of erect setae on pronotum proper strongly raised and thus the whole surface of pronotum proper seems granulose; distance of setal alveoli smaller than their diameters. Pterothorax : EL/EW 1.58–1.71; with golden inclined setae forming the two bands mentioned above, the golden setae also scattered in front of anterior band and extend to elytral apex after posterior band; black area before anterior band with sparse, long, yellow or deep brown erect setae. Puncture rows on black area before anterior band distinct; each interval with one row of tubercles except for the third interval where evidently uplifted forming a hump, with a cluster of tubercles; Puncture rows absent on black area after anterior band, where minute, evenly distributed, punctures are present. Male terminalia : Inner margins of parameres nearly straight, dorsal and ventral sinuses of tegmen triangular ( Fig. 20 ); phallus with ventral and dorsal spiculum very short, about half length as the apical sclerotized region ( Figs. 25, 26, 28 ); tergite VIII broad, with posterior margin rounded ( Fig. 23 ); sternite VIII with posterior margin shallowly and indistinctly concave ( Fig. 24 ). FIGURES 20–28. Terminalia of Hemitrachys tubericollis n. sp. 20–24 Holotype. 20 Tegmen in dorsal view; 21 Phallus; 22 Spicular fork; 23 Tergite VIII; 24 Sternite VIII. 25–28 Posterior phallus ( 25, 26 Dorsal view; 27 Lateral view; 28 Ventral view); from a paratype (No. IOZ(E)1890749). Female reproductive system : Length of ovipositor nearly as long as genital chamber extended out of ovipositor ( Figs. 29–31 ); dorsal lamina of ovipositor slightly bilobed apically ( Fig. 29 a), ventral lamina of ovipositor rounded apically ( Fig. 30 , vl); proctigeral bacculi nearly straight, continuous down to proctiger apex ( Fig. 29 , pb); ventral bacculi bent outward at posterior 2/5 ( Fig. 30 , vb); vagina ( Fig. 31 , vg) tubular, base of bursa copulatrix ( Fig. 31 , bc) slightly narrower than anterior end of vagina; bursa copulatrix tubular, a little enlarged towards anterior end, far longer than spermatheca ( Fig. 31 ); swollen zone ( Fig. 31 , sz) between vagina and spermathecal duct present; spermathecal duct ( Fig. 31 , spd) inserting on middle of swollen zone; spermatheca ( Fig. 31 , sp) globular, spermathecal gland ( Fig. 31 , spg) attached near spermathecal base; median oviduct ( Fig. 31 , mo) near bursa copulatrix; tergite and sternite VIII as in Fig. 32, 33 . Variation . In most cases, integument from which two bands of golden setae originated evenly yellow, but in the holotype and one paratype , integument from which the anterior band of golden setae originated with punctures black and intervals yellow. Distribution. China (Yunnan) ( Fig. 38 ). Etymology . The specific epithet " tubericollis " is the combination of the Latin noun " tuber " (= a protuberance, swelling excrescence), and the Latin word " collis "; referring to the whole granulose pronotum proper which formed by the raised setal alveoli, where is an important difference from H . bizonatus , previously the only known species in the genus.
