Generic characters. Head ( Figs 2 a–c) smooth, with metallic luster, occiput smooth to slightly coarse. Labial palpus curved, acute at apex; second and third segments approximately same length. Antenna shorter than forewing; scape elongate clubbed; flagellum with long ciliae on anterior margin in male. Fore- and hindwings narrowly lanceolate, widest near base; venation ( Fig. 2d ): forewing with R 2 or R 3 from anterior angle of cell, R 4 and R 5 stalked, R 5 reaching costal margin before apex, M 3 from posterior angle of cell, CuA 1 arising from near posterior angle of cell, CuA 2 reduced, 1A+2A connected about basal 1/7 of wing or not furcate; hindwing with cell open between M 1 and M 2, Rs running to near apex of costa, M 2, M 3 and CuA 1 stalked. Hind tibia and tarsus with bristles. Abdominal tergites with second to seventh in male and second to sixth in female bearing spines arranged in a slightly arched line along posterior margin ( Fig. 2e ).

Male genitalia. Uncus approximately same length as gnathos, with dense long setae laterally. Valva with cucullus setose on inner surface, sacculus well developed or weak. Vinculum narrowly banded; saccus short or not developed. Aedeagus usually cylindrical or tapered to apex, often produced to a club ventrodistally; cornutus present or absent.

Female genitalia. Papillae anales usually short, with many setae. Apophyses posteriores usually longer than apophyses anteriores. Ostium bursae opened on seventh abdominal segment posteriorly. Antrum funnel-shaped, sub-rectangular or bowl-shaped. Ductus bursae broad, often wrinkled. Corpus bursae with one or two signa. Basal part of ductus seminalis as well as region of transition between ductus bursae and corpus bursae usually with denticles or spines.

Diagnosis. The genus Stathmopoda is similar to Hieromantis Meyrick, 1897 in the second and third segments of the labial palpus approximately equal in length, and the antenna with flagellum having long ciliae in male. Stathmopoda can be distinguished by the antenna with scape elongate clubbed, and the forewing without large spots formed by tufted erect scales. In Hieromantis , the scape of the antenna is widened, and the forewing has large spots formed by tufted erect scales with metallic luster.

Remarks. Moths of the 13 species treated here share a combination of the following characters: the forewing usually has a large spot at both middle and end of cell respectively, sometimes it has longitudinal streaks or stripes at middle of cell; the hind tibia bears long bristles at basal 1/3, 2/3 and at apex respectively, and the tarsus bears bristles at apices of basal three tarsomeres. In male genitalia, the tegumen has a pair of small processes on the inner margin, the cucullus is large, convex dorsally, the aedeagus is tapering to apex, the cornutus consists of several large denticles or spines if present; in female genitalia, the antrum usually is sub-rectangular horizontally, the denticles at transition between ductus bursae and corpus bursae are present, and the corpus bursae has one or two signa.
