Rhinocylapidius Poppius 1915: 48 , type species: Rhinocylapidius velocipedoides Poppius 1915 (original designation), Rhinocylapidius: Bergroth 1920: 73 ; Carvalho 1952: 48, 1955a: 20, 1955b: 221, 1956: 5, 1957: 23; Schuh 1995: 35; Kerzhner & Josifov 1999: 9; Gorczyca 2000: 50, Gorczyca 2006: 72

Diagnosis. Recognized by having body elongate oval ( Fig. 2 View FIGURE 2 H–I); antennal segment II in males sinuate at basal one-third, thickened near base ( Figs. 2 View FIGURE 2 H–I, 4B); embolium broad, partly punctate ( Figs. 2 View FIGURE 2 H–I, 9C, D); ductus seminis with sclerotized portion inside endosoma rather long ( Fig. 10 View FIGURE 10 A). The genus is closely related to Rhinocylapus , in sharing the following features: dorsum usually dark castaneous ( Fig. 2 View FIGURE 2 H–R); head conical, distinctly elongated horizontally ( Figs. 1 View FIGURE 1 , 2 View FIGURE 2 H–R, 3, 16A); labrum often with spines in males; antenniferous tubercle distinctly removed from inner margin of eye ( Figs. 3 View FIGURE 3 , 16 View FIGURE 16 A); labial segment I long, reaching half of forecoxae; endosoma with more than one sclerite ( Figs. 10 View FIGURE 10 A, 11A,12A, 13A, 14A, 15B). It differs, however, in having sinuate and thickened antennal segment II, a broad and punctate embolium, and rather long sclerotized portion of ductus seminis inside endosoma ( Fig. 10 View FIGURE 10 A).

Redescription. Female. Macropterous, elongate oval. STRUCTURE AND VESTITURE ( Figs. 2 View FIGURE 2 H, 9C, D). Dorsal surface shining covered with fine, decumbent, scale-like setae. Head. Elongated horizontally, conical, covered with sparse setae, with rugose areas; clypeus slightly thickened toward apex, covered with slightly longer setae than those on remainder of head; eye relatively small, removed from pronotal collar, not reaching gula; antenniferous tubercle apparently removed from inner margin of eye; gula punctate, with single, long, protruding seta near antenniferous tubercle and with bundle of relatively long, semidecumbent setae beneath each eye; antennal segment I cylindrical, rather straight, sparsely covered with fine, semidecumbent setae; segment II shining, thin, slightly thickened toward apex, very sparsely covered with fine, relatively long, semidecumbent, setae, apex covered with relatively dense setae; segments III and IV covered with relatively long, dense, semidecumbent setae; rostrum thin, long, almost reaching abdomen apically; labial segment I long, reaching procoxae; segment IV long, very thin, and sharply pointed. Thorax. Pronotum. Trapezoidal; collar rugose, devoid of setae; anterior lobe impunctate, with distinct two incisions, each bordering posterior lobe and lateral margin; calli fused only at anterior portion of anterior lobe, divided by distinct sulcus at posterior portion; posterior lobe deeply and coarsely punctate, carinate laterally, with more or less distinctly marked, longitudinal sulcus or incision medially. Mesoscutum and scutellum. Scutellum somewhat convex, rugose. Thoracic pleura. Proepimeron impunctate anteriorly, less shining than anterior lobe of pronotum; remaining pleura rugose. Hemelytron. Deeply and densely punctate, shining, densely covered with fine, regular, scale-like setae, lateral margins distinctly rounded laterally; embolium with punctures, less dense than those on remainder of hemelytron. Legs. Long and thin, covered with relatively long, semidecumbent setae; pretarsal claw not toothed subapically.

Female genitalia. Not examined.

Male. Similar to female in overall appearance, but distinctly smaller and less ovoid. STRUCTURE AND VESTITURE ( Figs. 2 View FIGURE 2 I, 3E, 4B). Vestiture as in female; structure mostly similar to that in female. Head. Antennal segment I thickened at basal two-thirds, slightly curved; segment II distinctly thickened near base, then distinctly curved, remainder of segment straight and cylindrical, inner surface of segment, except for narrow, unthickened basal portion, covered with, very dense, small, protruding, slightly apically curved setae; labrum with well visible spines.

Male genitalia ( Fig. 10 View FIGURE 10 ). Endosoma composed of two lobes: one situated beneath secondary gonopore, larger, with long, widened proximally and folded sclerite, second lobe with relatively long, curved sclerite and terminating with a very long, stout, twisted, gutter-like sclerite.

Discussion. Rhinocylapidius was synonymized with Rhinocylapus by Gorczyca (2006). However, Rhinocylapus velocipedoides has a set of unique characters, the most important of which are the shape of antennal segment II in males ( Figs. 2 View FIGURE 2 I, 4B), a punctate and broad embolium ( Figs. 2 View FIGURE 2 H–I, 9C), and the endosoma with sclerotized portion of ductus seminis relatively long ( Fig. 10 View FIGURE 10 A). Therefore, Rhinocylapidius velocipedoides is here restored to the original genus.
