152CF0214C7254AA9B34F2FBFD025818.taxon	description	Description. Male (holotype). General color brownish yellow (Fig. 5 A, B). Facial part of head dark reddish brown, with an indistinct three-radial stripe between eyes; other part of head, clypeus, labrum and antennae brownish yellow; maxillary palps brownish yellow with reddish brown maculae; eyes black, ocellar spots whitish. Pronotum reddish brown, with two yellow areas anterolaterally (Fig. 5 E). Tegmina brownish yellow. Abdomen yellowish brown to reddish brown. Legs and cerci yellowish brown. Head slightly exposed. Ocelli subrectangular; interocular space distinctly less than the distance between ocellar spots and antennal sockets (Fig. 5 F). Pronotum subpentagonal, densely punctured. Tegmina and wings fully developed, exceeding the end of abdomen. Front femur Type C 1. Hind metatarsus not quite as long as other segments combined; four proximal tarsomeres with well-developed pulvilli, the one on the first tarsomere occupying almost the whole length of the segment; claws symmetrical and simple; arolium large. Supra-anal plate asymmetrical with hind margin deeply concave at the right side. Paraprocts of blaberid type, asymmetrical. Cerci stout at base (Fig. 5 G). Subgenital plate asymmetrical, with the right posterolateral corner slightly obtuse and upturned. Left style absent, right style broadly trigonal (Fig. 5 H). Male genitalia. Right phallomere with caudal part of sclerite R 1 T irregular and widened; R 2 short and curved; a well-developed projection arising from the junction of R 1 T and R 2; R 3 forked caudally, R 4 plate-like, R 5 absent (Fig. 5 I, J). Sclerite L 2 D divided into basal and apical parts: the basal part forked caudally with the inner margin indented; the apical part well sclerotized and more uniform in width than in other Pycnoscelus species, posterior margin toothed; apical membrane covered with microtrichia (Fig. 5 K). Sclerite L 3 hook without an apical incision, inner curved margin with a sharp convexity at apex; sclerite L 4 U present and divided into two parts (Fig. 5 L). Females. Thoracic segments and abdominal tergum black with minute punctures, abdominal sterna and legs reddish brown. Tegmina and wings absent.	en	Wang, Yi-Shu, Dong, Xiao-Jiao, Wang, Zong-Qing, Che, Yan-Li (2025): Taxonomic update of Pycnoscelus Scudder, 1862 (Blattodea, Blaberidae, Pycnoscelinae), with descriptions of two new species from China.
