description: Rhinocylapoides gen. nov.
Type species. Rhinocylapoides brachypterus sp. nov., here designated.
Diagnosis. Rhinocylapoides gen. nov. can be distinguished from other genera of the Rhinocylapus group, as diagnosed by Wolski (2010), by having the following set of features: body in males brachypterous (Figs. 1, 3); dorsum matte (Fig. 1); gula devoid of protruding, long setae; antennal segments III and IV rather short, not distinctly longer than II (Fig. 1); pronotum almost square; posterior lobe of pronotum almost impunctate, rugose, anterior lobe occupying most of pronotum (Fig. 1); posterior portion of proepisternum impunctate; ductus seminis with sclerotized portion within endosoma long, reaching apex (Fig. 5).
Description. Male. Brachypterous, suboval. STRUCTURE AND VESTITURE (Figs. 1–4). Dorsal surface matte, covered with sparse, very short, decumbent setae. Head. Elongated horizontally, conical, covered with setae more irregularly distributed than those on remainder of dorsal surface; longitudinal incision on vertex deep; labrum with 3 distinct spines; antenniferous tubercle distinctly removed from inner margin of eye; antennal segment I covered with sparse, black, almost decumbent setae; segment II bent medially, covered with very dense, minute, apically curved setae and with sparse, semierect setae, apparently denser at apex; antennal segments III and IV covered with relatively dense, semierect setae; labium very long, distinctly reaching beyond apex of pygophore; segment I undivided, long, reaching half of forecoxae; segments III and IV thinner than II; segment IV sharply pointed. Thorax. Pronotum. Nearly square; pronotal collar well separated from remainder of pronotum, somewhat rugose, devoid of setae; anterior lobe of pronotum broad, occupying most of pronotum, convex, with moderately deep incision medially; posterior lobe distinctly rugose; lateral margin apparently carinate; posterior margin incised medially. Mesoscutum and scutellum. Covered with setae sparser than those present on remainder of dorsal surface; scutellum slightly convex, with indistinct, sparse punctures medially. Hemelytron. Covered with moderately dense, rather small punctures, and with very short setae, situated at each puncture; apical portion of hemelytron enveloping membrane; corium and clavus weakly separated, almost fused; embolium impunctate; costal fracture absent; membrane distinctly abbreviated. Thoracic pleura. Propleuron impunctate anteriorly, rugose with indistinct punctures posteriorly; remaining pleura rugose. Legs. Long; femora and tibiae covered with moderately dense, semidecumbent setae; tarsus long; tarsomere I about three times shorter than II; tarsomere II divided; pretarsal claw toothed subapically. Abdomen. Covered with sparse, short setae.
Male genitalia (Figs. 5–8). Right paramere distinctly rounded with apical process flatted and furnished with spine at extreme apex, inner margin of body of right paramere rounded; endosoma composed of two membranous lobes; sclerotized portion of ductus seminis within endosoma long, curved apically, slightly reaching beyond apex; endosoma also with a curved sclerite situated apically.
Female. Unknown.
Etymology. The name Rhinocylapoides is used to denote the similarity of the new genus to the genera Rhinocylapidius and Rhinocylapus; gender masculine.
Discussion. The present new genus strongly resembles the genera Rhinocylapus Poppius, 1909 and Rhinocylapidius Poppius, 1915, sharing characters such as: horizontally elongated head (Figs. 1–2, 4); antenniferous tubercle distinctly removed from inner margin of eye (Figs. 2, 4); labial segment I long, reaching half of forecoxae; segments III and IV thinner than II; segment IV sharply pointed (Fig. 2); distinctly punctate hemelytron (Figs. 1, 3); endosoma with several sclerites and sclerotized lobes (Fig. 5). The new genus is distinct, however, by its suboval, brachypterous, rather small body; the matte dorsum; the shape and structure of the pronotum; and the structure of aedeagus. In the new genus the sclerotized portion of the ductus seminis is distinctly elongated, reaching slightly beyond the apex (Fig. 5). In the genera Rhinocylapus and Rhinocylapidius, the sclerotized part of the ductus seminis inside the endosoma is distinctly shorter (in Rhinocylapus it is usually strongly reduced) (Wolski 2010, Figs. 10A, 11A, 12A, 13A, 14A, 15A). The pronotum in the new genus is almost square, and the posterior lobe is rugose, almost devoid of punctures; anterior lobe occupies most of pronotum (Fig. 1), whereas all species belonging to the genera Rhinocylapidius and Rhinocylapus have the pronotum trapezoidal, with its posterior lobe distinctly punctate, about as long as the anterior lobe (Wolski 2010, Figs. 1, 2 H-R). Other features easily distinguishing the new genus from Rhinocylapus and Rhinocylapidius are the brachypterous, suboval, rather small (<3.1 mm) body, with its hemelytra apparently rounded laterally, distinctly broader than posterior width of the pronotum (Figs. 1, 3). All Rhinocylapus species are longer (usually> 5.0 mm), macropterous and elongated, with hemelytra being only slightly broader than the posterior width of the pronotum (Wolski 2010, Figs. 1, 2 J-R). The dorsal surface in the new genus is matte, whereas Rhinocylapus and Rhinocylapidius the dorsum is always shining (Wolski 2010, Figs. 1, 2 H-R). Furthermore, the new genus does not possess long, protruding setae on the gula, which are present in Rhinocylapus and Rhinocylapidius.
