چکیده
BACKGROUND The scarab beetle genera Orphnus Macleay and Delopleurus Boheman are most speciose in the Afrotropical region. However, a number of species are only known from type specimens, sometimes only from one sex. NEW INFORMATION New locality records of Orphnus drumonti Frolov (Orphninae) and Delopleurus naviauxi Frolov et Cambefort (Scarabaeinae) are given. The previously unknown female of the former and male of the latter species are described.

متن کاملRediscovery of the enigmatic Stenosternus costatus Karsch (Coleoptera: Scarabaeidae: Orphninae) from São Tomé Island.
Stenosternus Karsch, 1881 is one of the least-known genera of the Orphninae scarab beetles. It was described from a single specimen of the odd-looking S. costatus Karsch, 1881, from the island of São Tomé, Gulf of Guinea, West Africa. Karsch (1881) originally placed Stenosternus in the “Copridae” but later moved it to the Orphninae (Karsch, 1887). Since then, no more findings of S. costatus hav...
متن کاملStenosternus Karsch, a possible link between Neotropical and Afrotropical Orphninae (Coleoptera, Scarabaeidae)
The monotypical orphnine genus Stenosternus Karsch is known from a single specimen of Stenosternus costatus collected on the São Tomé island (Gulf of Guinea). The holotype of Stenosternus costatus Karsch is re-examined and its characters are discussed and illustrated. Although the genus was implicitly placed by Paulian (1984) in the Old World tribe Orphnini Erichson, re-examination of the holot...
