Hsiaotycoris tuberculatus Lü, Zhao & Cai , sp. nov. ( Figs. 1–29 )

Description. Coloration. Body mostly blackish brown to black, slightly shiny. Basal half of third antennal segment yellow; irregular stripes on femora, annulations on tibiae light yellowish brown; two markings on boundary of corium and membrane of hemelytron of male, basal markings of connexival segments, markings on two lateral sides of each segment of abdominal terga in female ( Fig. 1 ) yellow to brownish yellow; abdomen scattered with light brown or black spots of different sizes and with brown irregular markings; eyes of female light yellow with brown irregular markings, those of male brown; ocelli light yellow.

Structure. Distinct sexual dimorphism, female subapterous and abdomen moderately dilated ( Fig. 1 ), male macropterous and abdomen nearly parallel laterally ( Fig. 5 ). Body (except glabrous portion) clothed with pale yellow short bent setae; two series of long spines on lower surface of fore femur and fore tibia, each with a short pale seta on tip; antenna, head, pronotum, leg, hemelytron of female, terga of abdomen of female, margin of connexival segments, and scutellum scattered with thick brownish black and light yellowish brown setae of different lengths; fourth antennal segment and subapical portion of third segment in female, second to fourth antennal segment in male, with pale oblique short setae; tarsus, most of nearly apical portion of tibia, with pale oblique setae; venter of legs with oblique short setae. First antennal segment thickest, first to third antennal segments of female and first to second segments of male with setiferous tubercles dorsally ( Figs. 2–4 , 6, 7 ); interocellar space subequal to or slightly longer than distance between ocellus and ipsilateral eye; second rostral segment subequal to postocular portion in length. Collar of male with a setiferous tubercle; disk of posterior pronotal lobe depressed in male; posterior angles indistinct, lateral pronotal angles tuberculate, posterior margin nearly straight; scutellum with “ Y ”­shaped carina; hemelytra of female only reaching posterior margin of first abdominal tergum ( Fig. 1 ), those of male extending beyond abdominal tip ( Figs. 5 , 16 , 18 ); fore femur much thicker than mid and hind femora, fore legs with more and larger tubercles and spines than mid and hind legs ( Figs. 13–15 , 19–21 ). Outer margins of second to fourth and seventh connexival segments of female and those of third and fourth connexival segments of male nearly straight, outer margin of fifth and sixth connexival segments of female distinctly concave ( Fig. 1 ), outer margin of sixth connexival segment of male slightly concave ( Fig. 5 ); a pair of spiracles visible on dorsal surface of first abdominal tergum of female ( Fig. 1 ). Abdominal tip of female abdomen as shown in Figs. 9–11 . Pygophore without median process, middle portion of posterior margin nearly straight ( Fig. 22 ); paramere compressed, slightly twisted in middle ( Figs. 26–29 ); basal plate of phallus thick, plate bridge thin, pedicel long and strong ( Fig. 23 ); basal 2/7 of dorsal phallothecal sclerite slightly warped upward ( Fig. 23 ); struts Y­shaped ( Fig. 24 ); phallosoma ovate in dorsal and ventral views ( Figs. 24, 25 ).
