Otiothraea rotroui ( Kocher, 1961) comb. nov.

( Figs 18 , 126–127 )

Chilotoma rotroui Kocher, 1961: 238 (original description).

Type locality. Morocco: ‘Moyen-Atlas septentrional au S. de Taza (entre Bechyne et Meghraoua)’.

Type material examined. HOLOTYPE: ♂, ‘ Entre Bechyne / et Meghraoua / 10.6.48 [w, h] // Chilotoma /Rotroui m. [h] / Kocher det. [p]60 [h] / HOLOTYPE ♂ [red letters, w, h] // HOLOTYPE [r, p]’ ( PJCP). PARATYPE: ♀, ‘Entre Bechyne / et Meghraoua / 10.6.48 [w, h] // MUSEUM PARIS / 1971 / Coll. P. ROTROU [w, p] // ALLOTYPE [r, p] // Chilotoma / Rotroui m. [h] / Kocher det. [p] 60 [h] / ALLOTYPE ♀ [red letters, w, h]’ ( MNHN – coll. Rotrou).

Additional material examined. MOROCCO: Entre Bechyne et Meghraoua, 10.vi.1948, 2 ♂♂, P. Rotrou leg. ( MNHN – coll. Peyerimhoff).

Distribution. Morocco ( REGALIN & MEDVEDEV 2010b).

Comments. In habitus, O. rotroui is very similar to O. riffensis Romantsov, 2011 (cf. Figs 126–129 ). Both species differ in the colouration of pronotum ( O. riffensis has black anterior and posterior margins, O. rotroui has black anterior and posterior margins connected with two thin longitudinal stripes) and in the shape of clypeal incision (quadrangular in O. riffensis , subtriangular in O. rotroui , cf. Figs 127, 129 ).

Two specimens of O. rotroui found in Peyerimhoff ̓ s collection evidently originate from the same series as the two type specimens. Nevertheless, KOCHER (1961) explicitely described this species from ‘un couple’, thus, both males from Peyerimhoff ̓ s collection do not belong to the type material.
