Xenocylapidius rolandi Wolski & Gorczyca sp. n. Figures 7, 14, 37-41, 47-48

Diagnosis.

Recognized by the white head, with a fuscous vertex (Figs 7, 47); the blackish hemelytron with two large, white patches at base and at apex of corium (Figs 7, 47); the sclerotized portion of ductus seminis (DSS) composed of two parts: basal one, relatively long, gradually broadened toward apex and apical one, weakly ovoid basally and rounded apically; the apical half of endosoma composed of five strongly membranous lobes covered with tiny denticles; the endosomal sinistrolateral sclerite (SLS) small, nearly ovoid, with serrate margins (Fig. 37); and the apical process of right paramere tapering toward apex, with a subapical, short, obtuse process dextrolaterally (Fig. 41).

Most similar to Xenocylapidius bimaculatus in sharing large, pale patch near base of hemelytron (Figs 4, 7, 47). The present new species can, however, be distinguished by the blackish dorsum, with a large, white patch situated on hemelytron apically (Fig. 7, 47), and the shape of the male genitalia (Figs 37-41).

Description.

Male. COLORATION (Figs 7, 14, 47). Dorsum blackish with large white areas. Head. Mostly white; vertex fuscous; frons with two small, fuscous patches, each contiguous with inner margin of each eye and surrounding antennal insertion; gula blackish; antennal segments I and II fuscous; labial segment I blackish; remainder of labium dirty yellow. Thorax.Pronotum. Black. Mesoscutum and scutellum. Black. Thoracic pleura. Black. Hemelytron. Mostly black; corium and clavus with large, white patch near base; apex of embolium, apicolateral surface of corium, and medial portion of inner margin of cuneus with a large white patch; membrane dark grey. Legs. Procoxa black; meso- and metacoxae yellow, with a fuscous patch basally; femora and tibiae black; metafemur with a narrow, reddish annulation subapically and yellow, narrow annulation apically; metatibia with a yellow annulation basally and dirty yellow tinge at apical one third; tarsi dirty yellow. Abdomen. Black. STRUCTURE, TEXTURE, AND VESTITURE (Figs 7, 14, 47). Head. Antennal segment II weakly broadened toward apex, covered with moderately dense, semirecumbent setae, sparse on basal one-fifth of segment II and dense on remainder of segment, apical one fourth also with sparse, bristlelike, protruding setae. Thorax.Pronotum. Lateral margins incarinate, not elevated. Mesoscutum and scutellum. Scutellum flattened. Hemelytron. Covered with very short, relatively dense, adpressed, black setae.

Male genitalia.Aedeagus (Figs 37-38). Basal sac (BSC) nearly square; sclerotized portion of ductus seminis of endosoma (DSS) composed of two parts: basal one, relatively long, gradually broadened toward apex and apical one, weakly ovoid basally and rounded apically; apical half of endosoma composed of five strongly membranous lobes covered with tiny denticles; apical portion of endosoma with a single bundle of short spiculi (SP1); sinistrolateral sclerite (SLS) small, nearly ovoid, with serrate margins. Left paramere (Figs 39-40). Apical process: lateral view: slightly tapering toward apex, very weakly curved subapically; dorsal view: strongly tapering toward apex; sensory lobe: stout, obtuse. Right paramere (Fig. 41). Apical process: tapering toward apex, thin; dorsal view: tapering toward apex, with subapical, short, obtuse process dextrolaterally; paramere body: dorsal surface with sparse, long, protruding setae.

Etymology.

We are happy to name this species after our friend and colleague and the collector of the type specimen Roland Dobosz (Upper Silesian Museum, Bytom, Poland).
