Myochlamys convexiceps View in CoL (Desbrochers des Loges, 1896), comb. nov.

Sciaphilus convexiceps Desbrochers des Loges, 1896: 40.

Chiloneus convexiceps: Winkler, 1932: 1469 View in CoL ; Dalla Torre et al., 1937: 176; Borovec, 2013b: 379.

Type locality. Algérie, El Aley (Desbrochers des Loges, 1896).

Type material examined. Lectotype (here designated): 1 spec. ( MNHN, Pic coll.), ‘El Aley / 1895 [hw, rounded] // type [hw, yellow] // Sc. convexiceps / m. [hw] // TYPE [p, red] // LECTOTYPUS / Sciaphilus / convexiceps Desbr., 1896 / Borovec & Perrin desig. 2015 [p, red] // Myochlamys convexiceps, R. Borovec det. 2015 [p]’. Paralectotypes: 6 spec. on three pins (two pins with one specimen and one pin with 4 specimens) ( MNHN, Pic coll.), the same labels as lectotype, only with designation paralectotypus. Only one specimen bears the third label ‘ Sciaphilus / convexifrons / m.’, written probably by Desbrochers’s handwriting, with wrongly written species name.

Additional material examined. 1 spec., Algeria occ., Sahara, Mekmene Semamar, pr. Aïn Sefra, 25.iv.1987, J. Strejček lgt. ( JSPC); 11 spec., Algeria, Bou Saada ( MNHN). These 11 specimens pinned on 7 pins, the 2 first ones bear red label ‘TYPE’ and also label ‘ Sciaphilus cephalotes n. sp. [hw by Pic]’. Species with this name was never described and all the material is conspecific with lectotype of Sciaphilus convexiceps .

Remarks. The lectotype of Sciaphilus convexiceps is 3.81 mm long. All seven specimens clearly belong to the genus Myochlamy s Fairmaire, 1876 by lacking fronto-epistomal area separated posteriorly by carina, and represent the second species of the genus, which could be distinguished from the only known M. acutipennis Fairmaire, 1876 by short erect elytral setae and elytra in females wider, with distinctly rounded humeri.
