Discussion. Our examination of the holotype of D. bilineata did not reveal any morphological differences between it and other specimens bred from leaf axils of Dipsacus sp. and those from rock pools determined as D. saxicola . Therefore, we propose to treat D. saxicola and all previously associated specific names as new junior synonyms of D. bilineata . The original description of D. insignipalpis Kieffer, 1925 c and Culicoides dieuzeidei Vaillant, 1957 agree with the diagnostic features of D. bilineata , and we consider them new junior synonyms of that species. Dasyhelea bilineata is a western Palaearctic faunal element. The aquatic larvae live in small bodies of water including rock pools and leaf axils.
