Capsus pilifer Remane, 1950: 66 ; Wagner and Weber, 1964: 238; Vinokurov, 1977: 110.

Diagnosis. Distinguished from other congeners by reddish brown band of posterior margin of head and dark brown legs ( Fig. 9 ).

Redescription. Male: Body broadly oval, sometimes elongated oval, length 5.45–5.92. COLORATION: Overall color dark brown.

Head: dark brown, compound eyes dark brown; antennae generally dark brown, 1/2 basal part of third antennal segment pale brownt; tylus dark brown; posterior margin of head reddish brown band; rostrum almost brown. Thorax: pronotum dark brown, posterior margin reddish brown; collar dark brown. Scutellum dark brown; mesoscutum dark brown; ostiolar peritreme dark brown, hemelytra dark brown, outer margin of hemelytra reddish brown; cuneus dark brown, outer margin of cuneus grayish brown; embolium dark brown; membrane grayish dark brown. Legs almost dark brown, femora almost dark brown, tibiae dark reddish brown; tarsus pale brown, third segment dark brown, claw pale brown. Abdomen: dark brown. SURFACE AND VESTITURE: glossy, hemelytra covered with densely golden short pubescence; first antennal segment with short dense pubescence; hind femora with sparsely erect setae, tibiae with two rows of erect setae. STRUCTURE: Head: ocelli absent; vertex width longer than first antennal segment; first antennal segment relatively thick, second antennal segment clavate, third antennal segment relatively thinner than first and second antennal segment; proportion of first to fourth antennal segments 0.8:2:1:1.1. Rostrum reaching to hindcoxae; proportion of first to fourth rostral segments 0.6:0.7:0.5:0.6. Thorax: pronotum trapezoid, callus somewhat swollen; scutellum equilateral. Lateral margin of hemelytra curved, cuneal fracture developed. Legs generally slender. Abdomen: rounded, almost reaching to apex of membrane. GENITALIA: gonopore relatively short and rounded, with curved parameres ( Figs. 11–13 ); left paramere with hypophysis and sensory lobe somewhat widened; right paramere with hypophysis prominent horizontally; vesica with only one long spicule and two lateral sclerites, apex of spicule curved ( Figs. 14–15 ).

FEMALE: Ovoid, length 5.53–5.97. COLORATION: as in male. SURFACE AND VESTITURE: as in male. STRUCTURE: somewhat more rounded oval in overall shape than male.
