( Figs. 10 , 16–20 )

Capsus wagneri Remane, 1950: 66 ; Southwood and leston, 1959: 300; Wagner and Weber, 1964: 238; Vinokurov, 1977: 106.

Diagnosis. Different from other congeners by entirely dark brown head, and reddish legs with dark brown rings and pale rings ( Fig. 10 ).

Redescription. Male: Body somewhat elongated oval, length 5.86–6.8. COLORATION: Body primarily dark brown. Head: entirely dark brown; compound eyes almost dark brown; antennae generally dark brown, base of third antennal segment pale brown; tylus dark brown; rostrum almost pale brown. Thorax: pronotum dark brown, margin of posterior reddish brown; collar dark brown; mesoscutum dark brown, scutellum dark brown; ostiole peritreme dark brown; hemelytra dark brown, outer margin of hemelytra slightly reddish brown; cuneus dark brown; embolium dark brown; membrane somewhat pale brown. Legs generally reddish brown, femora almost reddish brown, with one or two dark brown rings; tibiae generally brown, middle part of tibia pale brown; tarsus generally pale brown, third segment dark brown, claws pale brown. Abdomen: dark brown. SURFACE AND VESTITURE: glossy; covered with densely golden short pubescence; first antennal segment with densely short pubescence; 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, proportions of first to fourth antennal segments 0.8:2:1:1.2. Rostrum reaching to midcoxae; proportion of first to fourth rostral segments 0.7:0.8:0.4:0.6. 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. 16–18 ); 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 triangular ( Figs. 19–20 ).
