description: Capitostylus Malipatil, gen. nov.
(Figs. 116–123)
Description. Body short, slightly oval (Fig. 116).
Head: Clypeus rounded; anterior of frons rather squarish (Fig. 118); ocular sulcus complete; head between eyes almost flat, appearing quadrate, densely covered with coarse punctures (Fig. 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); 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). 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). 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); 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).
Female genitalia: Spermatheca (Fig. 121) with lightly sclerotized bulb; duct short with 2–3 loose bends. Ovipositor (Figs. 122, 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.
