Type material examined. Sciaphilus nitens . Lectotype (here designated): 1 spec. (MNHN, Pic coll.), ‘ Algerie [hw] // Ouarsenis [hw] // type [hw, yellow] // Sc. nitens Pic [hw] // nitens var / du Maroc / cf coll. Rotrou / forme un peu moins / élargie [hw] // TYPE [p, red] // LECTOTYPUS / Sciaphilus / nitens Pic, 1904 / Borovec & Perrin desig. 2015 [p, red] // Chiloneus / cinerascens (Ros.), R.

Additional material examined. Rhinochrosis seminitidus . 1 spec. (MNHN, Hoffmann coll.), ‘ Algerie / Biskra / Bonnaire [hw] // Rhinochrosis / seminitidus / Hust. [hw] // Chiloneus cinerascens (Rosenh.), R. Borovec det. 2015 [p]’. 1 spec. (MNHN, Hoffmann coll.), ‘Marrakech / Maroc [hw] // Rhinochrosis / seminitidus Hust. [hw] / A. Hoffmann det. [p] // Chiloneus cinerascens (Rosenh.), R. Borovec det. 2015 [hw/p]’.

Remarks. The lectotype of Sciaphilus nitens is 3.51 mm long. Two specimens of Rhinochrosis seminitidus found in Hoffmann’s collection fit the description very well, so we have no doubts this species is merely a new subjective junior synonym of Chiloneus cinerascens . Chiloneus cinerascens is easily distinguished from all other species of the genus by moderately long, slender, piliform semierect setae on elytra, as well as piliform appressed elytral setae.
