Gorczyca, Jacek & Chérot, Frédéric, 2008, Stysiofulvius, a new genus of Cylapinae (Hemiptera: Heteroptera: Miridae) from the Peninsular Malaysia, Acta Entomologica Musei Nationalis Pragae 48 (2), pp. 377-384 : 378

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 ’.
