Macrolenes dentipes ( Olivier, 1808)

( Figs 17–21 )

Clytra dentipes Olivier, 1808: 857 (original description). Clythra crassimana Forsberg, 1821a: 262 , 276 (original description), syn. reconfirmed

Type localities. Clytra dentipes : ‘midi de lʼEurope, sur la côte de Barbarie, dans les îles de lʼArchipel’ [= southern Europe, coast of northern Africa, Mediterranean islands]. Clythra crassimana : not stated.

Type material examined. Clytra dentipes : not examined.

Clythra crassimana : HOLOTYPE: J, ‘ Uppsala Univ. Zool. Mus. / Thunbergsaml. nr. 8194 / Typsaml. nr. 1584 / Clythra crassimana Forsberg 1821 [r, p] // crassimana. / 10 [box label, w, h]’ ( UUZM).

Distribution. Mediterranean species (for details see REGALIN & MEDVEDEV 2010).

Comments. The holotype of Clythra crassimana is in very poor condition, the preserved parts are: elytra, hind wings, part of thorax and both mid legs. However, these parts well agree with the paler forms of Macrolenes dentipes including the characteristic shallow subapical emargination on the ventral side of mid femora. As a result, I confirm the synonymy of both taxa as was already published by LACORDAIRE (1848) and widely accepted by subsequent authors (e.g. GEMMINGER & HAROLD 1874, CLAVAREAU 1913, REGALIN & MEDVEDEV 2010).
