Longarista Volynkin, 2019, Ecologica Montenegrina 20: 98 (Type species: Miltochrista longaria Daniel, 1951 , by original designation).

Diagnosis. Small moths with orange or red colouration and blackish pattern. Species of the genus resemble superficially some species of Ammatho and females of Fossia . Antennae of both sexes are ciliate. The autapomorphic feature of Longarista male genitalia is the unique structure of its juxta, which is swollen, heavily sclerotised and densely covered with small denticles, whereas other members of the generic complex have flattened juxta, only Ammatho (Idopterum) has lateral swollen dentate lobes, and Fossia has the juxta with serrulate apical processes. In addition, the male genitalia of Longarista are characterised by the combination of such features as (1) the absence of a medial costal process; (2) the absence of a distal membranous lobe of valva; (3) the prominent and heavily sclerotised distal costal and saccular processes; and (4) the aedeagus vesica having several diverticula armed with clusters of small but stout trigonal cornuti. The female genitalia of Longarista are characterized by the presence of a swollen postvaginal plate, which is absent or flattened in other genera of the Asura / Miltochrista generic complex.

Distribution. Southern China and northern Indochina.

Number of species. The genus comprises two valid species reviewed by Volynkin (2019a).
