Genus Tiana Grishin, 2019

Type species: Ebrietas niger Williams & Bell, 1940 .

ZooBank registration: B9382699-24FB-4466-B39B-94E6B544C425

Diagnosis: The genus was defined as a clade from about 10 Mya that contains the species Ebrietas niger Williams & Bell, 1940 , and putatively synapomorphic DNA characters for this clade were given ( Li et al., 2019). Phenotypically, species in this genus would key to F.7.3 or F. 7.4 in Evans (1953). Combination of the following characters is diagnostic of the genus ( Fig. 21 ): forewing discal cell very short, outer margin of both wings evenly convex, palpi short, antennal shaft plain and club slender, nudum of 21-24 segments, males with costal fold on forewing, no tibial tufts, both wings dark, almost unmarked or with two paler, ochreous brown bands above cut by dark veins without violet sheen, below distal half of hindwing paler with darker veins. Differing from Tosta Evans, 1953 and Iliana E. Bell, 1937 by uncus without projections, either undivided or with very short knob-like arms, harpe simple, without processes, almost rectangular, unturned with serrated dorsal margin, not prominently separated from the ampulla.

Species included: Ebrietas niger Williams & Bell, 1940 and Anastrus platypterus Mabille, 1895 .

Parent Taxon: Tribe Carcharodini Verity, 1940 .
