Capitostylus Malipatil View in CoL , gen. nov.

( Figs. 116–123 View FIGURES 116 – 118 View FIGURES 119 − 123 )

Description. Body short, slightly oval ( Fig. 116 View FIGURES 116 – 118 ).

Head: Clypeus rounded; anterior of frons rather squarish ( Fig. 118 View FIGURES 116 – 118 ); ocular sulcus complete; head between eyes almost flat, appearing quadrate, densely covered with coarse punctures ( Fig. 118 View FIGURES 116 – 118 ), punctures sparse in apical 1/3, head below adjoining eyes sparsely punctate, gular area impunctate and slightly depressed; eyes wrapping around pronotal margin at anterior corners ( Fig. 118 View FIGURES 116 – 118 ); bucculae produced near base as flaps, then gradually diminishing posteriorly almost to surface of head, meeting roughly in a Y junction at level of antennifers, thereafter extending as a line to base of head. Labium extending to middle coxae, 1st segment to base of head. Antennae rather short and robust in comparison with body length; 1st segment shortest, 2nd and 4th segments subequal.

Thorax: Pronotum with lateral margins narrowly carinate; width at anterior margin subequal to median length; dorsally coarsely punctate; calli and humeral angles smooth and impunctate ( Fig. 117 View FIGURES 116 – 118 ). Thoracic pleura with coarse punctures; metathoracic scent gland opening narrow and directed posteriorly, conspicuously raised above surface; evaporative area well defined. Scutellum wider than long, densely and coarsely punctate basally and on sides, with triradiate impunctate elevation ( Figs. 116, 117 View FIGURES 116 – 118 ). Hemelytra macropterous, slightly exceeding abdomen; corium with costal margins parallel to level of apex of scutellum, then gently arcuate, widest at level of base of membrane.

Abdomen: Spiracles II–IV dorsal on connexiva, V–VII ventral. Sutures between terga IV–V and V–VI strongly curved caudad from margin to meson, with distinct scent gland scars; scar between V–VI slightly wider. Inner laterotergites present, very pale, obscure. Terga III, IV and V with coarse punctures of variable size on middle area ( Fig. 120 View FIGURES 119 − 123 ); terga VI with a few obsolete punctures; terga VII impunctate. Trichobothria on sternum III in a triangle, on IV linear, on V–VII are in full (trichobothrial) complement (3:3:2), and in all the inner of the 2 posterior trichobothria is the smallest. Sterna III and IV sublaterally with a few coarse punctures ( Fig. 119 View FIGURES 119 − 123 ).

Female genitalia: Spermatheca ( Fig. 121 View FIGURES 119 − 123 ) with lightly sclerotized bulb; duct short with 2–3 loose bends. Ovipositor ( Figs. 122, 123 View FIGURES 119 − 123 ) with first ramus traversing to 5/6 length of first gonapophysis, and with one row of sparse setae on margin; second gonapophysis spatulate with sparse setae in two rows on dorsal aspect; second gonocoxae crescentic.

Type species: Capitostylus kurandae Malipatil sp. nov.

Notes. This genus is related to Stylogeocoris Montandon , but it can be readily distinguished by the presence of dense coarse punctures on the head between the eyes, and a few sparse coarse punctures arranged in groups on the lateral areas of abdominal sterna III and IV.
