Diagnosis. See the generic diagnosis.

Description. COLORATION (Figs. 1–2). Dorsal surface dark brownish fuscous with dirty yellowish areas. Head. Mostly fuscous, with two dirty yellowish, indistinct patches on vertex, each bordering lateral and posterior margin of eye; longitudinal incision of vertex with dirty yellowish tinge along whole its length; antennal segment I dirty yellowish; segment II varying from fuscous to almost black, with narrow yellowish tinge basally, sometimes also with relatively broad yellowish annulation medially; segments III and IV fuscous; labium yellowish. Thorax. Pronotum. Dark brown fuscous, nearly black, sometimes tinged with dark brown on anterior lobe. Mesoscutum and scutellum. Mostly dark brown, with dirty yellowish patches laterally and with narrow, yellow patch apically. Hemelytron. Mostly dark brown with darker, nearly fuscous basal portion, apical portion with indistinct tinge, and with distinct, yellowish patch; corium with indistinct, dirty yellowish tinge medially; strongly reduced membrane dark grey. Thoracic pleura. Fuscous to black; metathoracic scent efferent system contrastingly yellow. Legs. Dark brown yellow; coxae varying from yellow to dirty yellowish; femora dark brown tinge with dirty yellow; tibiae dark brown; tarsi dirty yellowish. Abdomen. Brownish.

Measurements. 3 (n=3; holotype measurements in parentheses): body length (measured from the apex of clypeus to the margin of the membrane) 2.9–3.05 (3.05), width (measured between lateral margins of hemelytra) 1.10 (1.10). Head. Length 0.87–0.9 (0.87), interocular distance 0.4, diameter of eye in dorsal view 0.15. Antenna. Length of segment I 0.77–0.88 (0.77), II 1.2–1.45 (1.2), segments III and IV strongly twisted, and immeasurable in the examined specimens. Length of labium 4.0–6.7 (4.0). Pronotum. Length 0.55, width of anterior margin 0.5, length of lateral margin 0.63–0.65 (0.65), width of posterior margin 0.78–0.8 (0.78).

Etymology. The name “ brachypterus ” is used to denote the shape of hemelytra with its distinctly abbreviated membrane.

Biology. The type series was collected from fungi in a deep, shaded stream valley covered with a tropical rain forest (J. Hájek, pers. comm., see also Fig. 9).

Distribution. Malaysia (Pahang: Tanah Rata).
