HEKISTA KIRKALDY, 1902

FIGS 3 , 26, 28 , 34, 35 , 70, 71 , 90, 91, 100, 101

Hekista Kirkaldy, 1902: 248 . Type species: Hekista laudator Kirkaldy, 1902 (by monotypy).

Diagnosis

Recognized by the following combination of characters: body elongate, parallel-sided ( Fig. 3 ); antennal segment I equal to or slightly shorter than head width; labium reaching middle of mesosternum, labial segment IV claw-shaped, distinctly longer than wide, twice thinner than segment III and strongly tapering from base ( Fig. 26 ); pronotal collar matt, equal to width of antennal segment I; pronotum with deep punctures ( Fig. 3 ); exocorium narrow, whitish; cuneal fracture not incised; cuneus narrowly triangular, at least twice as long as wide at base; genital capsule without additional processes; right paramere large, less than twice as small as left paramere; left paramere falciform, with indistinct sensory lobe and almost straight, gradually tapering apical process ( Fig. 71 ).

Hekista is somewhat similar to Bryocorella (see relevant section) and Cobalorrhynchus . Differs from the latter in the narrow, parallel-sided body, colour pattern of hemelytron, deep punctures on pronotum, and deeply scalloped sides of scutellum.

Diversity and distribution

The genus includes four species, Hekista papuensis Carvalho, 1981 and Hekista similaris Carvalho, 1981 known from Papua New Guinea, Hekista laudator Kirkaldy, 1902 known from Indonesian islands, and Hekista novitius (Distant, 1904) described from northeastern India.
