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 .
