Acropentias Meyrick, 1890 View in CoL . Trans. Ent. Soc. Lond., 1890: 470. Type species: Sparagmia obtusalis Christoph, 1881 , by monotypy (junior synonym of Micraeschus aureus Butler, 1878 ).

Diagnosis. The genus can be distinguished from other genera by vein R 1 stalked with R 2+3+4 and M 2 short stalked with M 3 on forewing.

Wings ( Fig. 9 View Figs 7–12 ). Forewing protruded at middle of outer margin; R 1 to R 4 stalked; R 5 arising from upper angle of cell; M 1 from discocellulares; M 2 and M 3 short stalked, arising from lower angle of cell; Cu 1 and Cu 2 before lower angle of cell; CuP present. Hindwing with Sc+R 1 and Rs stalked, arising from upper angle of cell as M 1; M 2 and M 3 from lower angle of cell; Cu 1 and Cu 2 before lower angle of cell.

Male genitalia. Uncus nearly triangular, dorsal suffused with dense setae; gnathos absent; valva nearly rectangular, covered with dense setae; saccus small; coremata absent; juxta like a rolling column; aedeagus slender, without obvious sclerotized process.
