Derelomus turneri Marshall, 1935: 139 Ebenacobius Haran, a new southern African genus of flower weevils (Coleoptera: Curculioninae: Derelomini) associated with dicotyledonous plants Haran, Julien Benoit, Laure Procheş, Şerban Kergoat, Gael J. European Journal of Taxonomy 2022 2022-05-05 818 1 1 54 (Marshall, 1935) Haran & Benoit & Procheş & Kergoat 2022 Marshall 1935 [456,909,1739,1766] Insecta Curculionidae Ebenacobius Animalia Coleoptera 45 46 Arthropoda species turneri gen. et comb. nov.   Figs 3H, 5F, 6Q      Derelomus turneri Marshall, 1935: 139.    Differential diagnosis   Ebenacobius turneri gen. et comb. nov.can be distinguished by the combination of appendiculate claws and elytra with distinct but recumbent setae, as long as or shorter than width of interstriae. This species is very close if not conspecific with  E. atratus gen. et comb. nov.(see remarks section). The two species have been distinguished based on vestiture of elytra (Guillermo Kuschel unpubl. data), the interstriae bearing a row of long, erect piliform setae (short, not or slightly raised squamiform setae in  E. atratus).    Type material    Lectotype(here designated) REPUBLIC OF SOUTH AFRICA• ♂; “ Aliwal North,; Cape Province[REPUBLIC OF SOUTH AFRICA,  Eastern Cape Province];  Dec. 1922.” “S.

Cotype ♂” was identified. As the description does not refer to a specific holotype, this specimen is here designated as the lectotypefor this species and labelled accordingly. Other specimens of the syntypic series were labelled as paralectotypesof  Derelomus turneri. The name  Derelomus turneriis most probably a junior synonym of  D. atratus gen. et comb. nov.The lectotypeand all the specimens of  D. turneriexamined correspond exactly to the description of  D. atratusmade by Hessebased on a single specimen. The only difference lies in the density of scale cover on the dorsum, but the examination of large series of specimens shows that this feature is quite variable at a locality, ranging from narrow and golden to wide and whitish. The actual synonymy could not be made in this study as the holotypeof  E. atratusis currently lost (see remarks section of that species).   Life history The host plant of this species is unknown, it was recorded once on  Diospyros lycioidesDesf.from the family Ebenaceae. This species was collected in the same sampling event with  E. grobbelaarae gen. et sp. nov.and  E. rectirostris gen. et sp. nov.Adults were collected from September to December.    Distribution  Republic of South Africa( Eastern Cape, Gauteng, Kwazulu-Natal, Limpopo, Mpumalanga, Northern Cape, North West& Western CapeProvinces). 3765338339 1922-12 NHMUK R.
