Type species. Punctacorona triplosticha sp. nov.

Diagnosis. Clypeus longer than paraclypei, with 4 peg-like setae marginally, paraclypei with 6 peg-like setae marginally, all marginal setigerous punctures arising from its own well-developed tubercle; ocelli present ( Fig. 2A, B ). Pronotum trapezoidal, almost parallel-sided, anterior angles expanded, coxal combs scale-like. Scutellum triangular, about 2 times longer than claval commissure. Clavus with 3 rows of coarse punctures ( Fig. 3 ); claval commissure present; evaporatorium on metapleuron extensive, covering most of segment, very large, with mycoid micro sculpture ( Fig. 4 D, I ), metapleuron neighboring to posterior margin of evaporatorium carinate ( Fig. 2B ; Fig. 4D ); R+M separated from C+Sc at 1/5 of corium, anterior margin of forewing angulated.

Etymology. The generic name is a combination of the Latin Punct - (“Little dot”) and corona (referring its clypeus longer than paraclypei, with peg-like setae), gender feminine.
