Specimen from Madagascar in USNM


Distribution

Ivory Coast, Madagascar, Malawi, South Africa. MAP

Diagnosis

Distinguished from other species of Oberthuerella by the extremely short vertical keel on the face, not extending beyond the toruli; this feature is also shared with O. triformis, but in this latter species, the scutellar spine is remarkably short, whereas in O. lenticularis, the scutellar spine is roughly equal in length to the petiole.  Finally, the pronotal and mesoscutal sculpture in O. lenticularis is deeply foveate, so much so that the general appearance of this species craggy.

Note on Holotype

This name was originally published as an image with an associated name in a larger volume on Madagascar (Saussure, 1890).  Article 12.2.7 of IZCN (2000) stipulates the image of O. lenticularis satisfies indication of a new genus and species, even though no description nore holotype was provided.  Thus, the genus and species names are available, and the illustration of Saussure (1890) serves as the holotype.

Unknown.
