New species and records ofPalaearctic Trichoptera in the material of

; the HNHM 95 Etymology - The name was given to remember the ancient Scythian inhabitants of the Heavenly Tian Shan Mountains, the yuechi Hun tribes, the ancestor of Kushans who established the great Kushan Empire in North and Middle India including Baktria, Gandhara and Malva during the 1st to 3rd centuries AD. Diagnosis - This new species belongs to Lepidostoma ferox branch, but without pseudocells on forewing; most similar to Lepidostoma nigrescens (MEY et JUNG, 1989) described from Kirgizistan. The new species differs by having smaller size, discoidal cell much longer than its stalk on forewing, not shorter or equal; much shorter fork V on forewing, not reaching almost to wing base; the two basomedian processes on scape occupy only one fourth of the scape, not one third; cerci trilobed, its shortly bilobed mesal lobes produced posterad, as a result the pair of cerci together not straight or excised in dorsal view; gonopods with dorsosubapical hump and armed with very characteristic stout megasetae on ventral setiferous area.
