Generic characters. Adult ( Figs 2 View FIGURES2‒6 ¯4). Head with appressed scales. Proboscis well-developed. Labial palpus upturned in male ( Fig. 2a View FIGURES2‒6 ), only extended forward and longer in female ( Fig. 2b View FIGURES2‒6 ); second segment usually longer than diameter of eye; third segment short, greyish, white at apex. Antenna filiform, cilia in male usually same length as diameter of flagellum. Forewing narrowly elongate, with six or more scale tufts roughly scattered in discal cell, in some species often with a triangular or sub-triangular black basal patch ( Fig. 3 View FIGURES2‒6 ); hindwing trapezoid. Wing venation ( Fig. 4 View FIGURES2‒6 ): forewing with R veins separate, M1 closer to R5 than to M2, M3 and CuA1 close at base and from lower angle of cell, CuA2 from lower margin before lower angle of cell, 1A+2A furcate basally; hindwing with Rs reaching apex, M1 developed or fully vestigial, M2 absent, M3 and CuA1 from lower angle of cell, stalked at base, CuA2 from about distal 1/4 of lower margin of cell.

Male genitalia ( Fig. 5 View FIGURES2‒6 ). Uncus reduced to a small conical lobe, fused to tegumen. Gnathos reduced. Tegumen short, narrowly banded anterolaterally. Valva varied in shape, with a rod-shaped, weakly sclerotized dorsobasal process and a wedge-shaped, heavily sclerotized ventrobasal process, both processes usually extending outward parallelly. Transtilla usually banded. Vinculum elongate triangular, narrowed anteriorly; saccus slender, narrowly rounded or pointed apically. Juxta often short. Ectophallus (specialized anellus) often developed, triangular. Aedeagus elongate, slender; cornutus being a single spine, or double spines, or a cluster of fine spines.

Female genitalia ( Fig. 6 View FIGURES2‒6 ). Eighth sternum weakly sclerotized. Ostium bursae large and elongate. Antrum (= colliculum in Diakonoff 1989) usually well-developed, heavily sclerotized. Ductus bursae slender. Corpus bursae elongate ovate; signum absent.

Diagnosis. Commatarcha is similar to Bondia Newman, 1856 by the forewing having several scale tufts. It can be distinguished from Bondia by male genitalia: the valva has two dorsobasal processes in Commatarcha ; Bondia has a valva with distal half often divided into two to four lobes, but lacking the dorsobasal processes ( Davis 1969).

Distribution. China, Japan, Kashmir, Korea, Pakistan.
