Abstract

In the course of investigations at steppes in Algeria, Galls on Artemisia herba alba were recorded accidentally for the first time in 2015 at the region of Saida and Sidi Bel Abbes in the Northwest of the country. The associated host plants and midge-induced galls were collected and kept in glass boxes until the emergence of adult midges for the determination of specie.The identification of Rhopalomia navasi (Tavares,1904) was done by the Dr Marcela Skuhravá. Tavares is the first who signaled the presence of this specie in Algeria and described it with other gall midges species. Without access to Tavares’s either large collection of galls and adults or lost of most Algerian samples. This collection is the first resurgence of Rhopalomia navasi in Algeria ; we aim to present it through its data.
