Borovec det. 2015 [p/hw]’.

Sciaphilus pruinosus . Lectotype (here designated): 1 spec. ( MNHN, Desbrochers coll.), ‘ PROV. D´ ORAN / Oued Riou / de Vauloger [p] // type [hw] // TYPE [p, red] // Ex Museo / Desbrochers / 1914 [p] // LECTOTYPUS / Sciaphilus / pruinosus Desbr., 1896 / Borovec & Perrin desig. 2015 [p, red] // Chiloneus / pennatus (Fst) , R.

Additional material examined. 14 spec., Algeria, Prov. d’Oran, Oued Riou, de Vauloger ( MNHN); 1 spec., Algeria, Oran, Lalla—Maghnia, V. M. Duchon ( MNHN); 3 spec., Algeria, Ammi Mousa, ii.1894 ( SMTD); 1 spec., Algeria, Reitter ( SMTD); 1 spec., Algeria, Teniet el Haad ( SMTD); 1 spec., Algeria, Prov. d’Oran, Oued Riou, de Vauloger ( NHRS).

Remarks. The lectotype of Sciaphilus dividuus is 3.25 mm long. The lectotype of Sciaphilus pruinosus is 3.38 mm long. Both lectotypes are conspecific with the type of Sciaphilus pennatus , thus Sciaphilus dividuus is a subjective junior synonym. We also confirm synonymy of Sciaphilus pruinosus . Chiloneus pennatus is easy to distinguish from all other Chiloneus species by appressed scales on elytra trifid, deeply divided into three piliform lobes apically.
