Diagnosis. Belonging in the Graphocaeciliini . Ocelli absent. Forewing veins with a row of conspicuous setae, except on Cu2. Hypandrium with sides and posterior border distinctly thickened, surface setose, bearing two mesal macrosetae. Endophallus large, formed by a compact group of small sclerites. Aedeagal arch projected posteriorly in the middle, projection wide based. External parameres anteriorly wide, narrowing distally to blunt ends. Posterior border of clunium, over the area of the epiproct, with an almost quadrate, densely spinose projection, extending to about half the length of the epiproct; border of clunium, over the area of each paraproct, next the middle projection, with a row of 8–10 macrosetae. Male paraprocts with a distinct, elongate, sclerotized anterior projection, joined distally to clunium. Female subgenital plate broad, setose, slightly concave in the middle. Gonapophyses with V1 short, slender; V2+3 elongate, distally pointed, with a field of macrosetae.

Type species. Acantholachesilla saltoensis sp. n.

Comments. This genus differs from Dagualachesilla in the structure of the clunial projection, in having two mesal macrosetae on the hypandrium, and in the structure of the aedeagal arch and external parameres. It differs from Dagualachesilloides in having a clunial projection over the area of the epiproct, that is absent in the latter, in having two mesal macrosetae on the hypandrium, and in the structure of the aedeagal arch and external parameres.
