Rhinophrus Hsiao 1944

Genus Rhinophrus Hsiao, 1944 Rhinophrus Hsiao, 1944: 382. Rhinophrus – Carvalho 1957: 33 (catalog). — Gorczyca 1994: 181 (discussion); 1996: 332 (discussion); 2000: 49 (list); 2006: 66 (catalog). — Schuh 1995: 37 (catalog); 2002–2013 (online catalog). non Acrorrhinium Noualhier, 1895 – Gorczyca 1994: 181. Diagnosis Easily distinguished from other cylapines by the following combination of characters: body strongly elongate (Figs 35, 43); head with protruding, pointed frons and compressed clypeus (Figs 43–45); procoxae much longer than meso- and metacoxae (Fig. 44); scent gland efferent system weakly developed, restricted to posterior angle of metepisternum (Fig. 46); central row of tiles on pretarsal unguitractor absent (Fig. 47). Remarks As misplaced previously under a unique hallodapine genus Acrorrhinium (Gorczyca 1994), Rhinophrus is characterized primarily by the remarkably slender body shape (Fig. 43) and a projection on the frons (Fig 44). However, the plausible systematic position of Rhinophorus is yet to be determined (see Discussion below).
