REMARKS. Chrysis leachi var. cyanea du Buysson, 1908 was described on five female specimens collected by P. Teihlard at Wadi Hoff (Cairo). Linsenmaier (1959) replaced the name, homonym of C. cyanea Linnaeus, 1758 , with C. nilensis and upgraded the taxon to specific rank. Two specimens of C. nilensis were found in Linsenmaier's collection, one from

Sudan and another one from the Ivory Coast. The presence of C. nilensis in Sudan was expected; in fact, the locality El Damer is located along the Nile river. More interesting is the finding of this species in Ivory Coast. All examined specimens in collections show a noticeably variability in punctation, shape of the apical tooth on the third tergum, and shape of the black spots on the second metasomal sternum. Since Linsenmaier considered the

Sudanese specimen a member of a separated species (and proposed the name afroleachii,

never published), we here designate the lectotype of C. leachi var. cyanea to fix the current interpretation of the species sensu Linsenmaier (1959). An examination of further material is anyway need to evaluate the variability of this taxon in Africa, and eventually proceed with the description of related species.
