Hasora anura, the slate awl,[2][3] is a species of hesperid butterfly found in Asia.
In India the butterfly ranges from Mussoorie eastwards to Sikkim, the Shan states in Myanmar, Thailand, south-west and central China (Yunnan).
Hindwing with the basal two-thirds much darker than the outer third, the dark portion well-defined, bearing towards the abdominal margin on the dividing edge a small prominent ochreous spot, an ochreous anteciliary line from the anal angle to the first median nervule, the ochreous spot and line obscure in one specimen; a prominent whitish spot in the middle of the disc in one specimen, obscure in the other.
Underside, forewing with the spots of the upperside showing through, the inner margin broadly bright ochreous: otherwise as in the male.
Closely allied to the common Hasora badra, Moore, from which it differs in both sexes in having no large anal lobe to the hindwing, this lobe being present in H. badra and coloured black on the underside, of which black patch there is no trace in H. anura; the latter also is a smaller insect; the female differs in having the three large discal yellow spots of the forewing considerably smaller, and of a deeper richer yellow.
