Haris Two new Dolerus species (Hymenoptera: Tenthredinidae) - Two new Dolerus species are described hereunder as Dolerus nigrominutus sp. n. and D. afghanicus sp. n. and compared to D. hibernicus Lacourt, 1988, D. klutchianus Malaise, 1931, D. variegatus Jakovlev, 1891, D. pakistanicus Muche, 1982 and D. kurahshii Togashi, 1989.

Body entirely black, apical half of mandibles red, cenchri white, wings hyaline, venation black, stigma black with brown margin. Vertex and temples deeply, roughly and densely punctured.
