Stysiofulvius gen. nov.
Type species. Stysiofulvius hulinkai sp. nov., here designated.
Description. Macropterous. Body stout, smooth, covered with fine setae.
Head contiguous with the anterior margin of pronotum. Frons flat; clypeus short and narrow; vertex with an occipital carina. Antennae inserted on small tubercles contiguous with the inner margin of eyes. First antennal segment thin, short, thickened towards apex; second antennal segment club-like, covered with thick setae; third and fourth segments thin, covered with fine long and short protruding setae; fourth antennal segment divided medially. Rostrum relatively long, reaching beyond metacoxae; first segment distinctly thicker than second.
Pronotum broad, anterior lobe of pronotum convex, with a small, longitudinal sulcus in the middle, posterior and lateral margins rounded, humeral angles slightly elevated. Anterior angles with a small tubercle bearing a long bristle. Mesoscutum well exposed; scutellum slightly convex.
Hemelytra lacking wide and deep punctation but provided with small orange yellow callosities or patches, covered with fine setae; medial fracture and R + M very short (Fig. 1); costal fracture distinct; cuneus short, broad.
Ventral surfaces. Forefemora enlarged, covered with a row of thick protruding setae in the inner part; meso- and metafemora covered with dense, short setae. Meso- and metafemora bearing only three and four trichobothria respectively. Tibiae and tarsi covered with short setae. Tarsi two-segmented, first segment very short, second segment divided by an oblique suture; claws with a very small, hardly visible subapical tooth.
Male genitalia. Parameres distinctly asymmetrical; phallus membranous, with sclerotised spiculi (Figs. 2-4).
Female genitalia. Vagina complex including numerous sclerites. Inter-ramal sclerites (= A- structures) transversally subdivided by a membranous area.
Etymology. This genus is dedicated to our friend Prof. Pavel Štys in recognition of his invaluable contribution to the study of Heteroptera . It is named for Stys in combination with ‘- fulvius ’.
