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).
