Evans (1946: 644) resurrected the Fabrician name tertullianus and applied it to this insect, which had been known as grisea for better than half a century. We are following his lead with strong reservations, chiefly because Berger ( 1962: 450) also uses tertullianus. Our hesitation is based in part on Fabricius' type locality, the always vague "Indiis", and in part on the original description which could as easily be placed as one of the neotropical hesperiids (especially of the genus Staphylus) as the present species. It appears that an appeal for the suppression of tertullianus may be in order.
Evans (1937: 46, as grisea) records this species from Guinea to Gabon and the Congo. It is apparently abundant throughout its range and is one of the more frequently cited species in small regional lists.

In addition to these specimens there are examples in Carnegie Museum from Cameroon and Gabon.

Sarangesa tertullianus, commonly known as the blue-dusted elfin, is a species of butterfly in the family Hesperiidae. It is found in Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Gabon, the Republic of the Congo, the Democratic Republic of the Congo and Uganda (from the western part of the country to Bwamba). The habitat consists of forest edges and secondary growth near forests.

Adult males are attracted to flowers and bird droppings and mud-puddle.
