Aulidiotis Meyrick, 1925

Aulidiotis Meyrick, 1925: 182 .

Type species: Ceratophora phoxopterella Snellen, 1903 , by original designation and monotype.

Ocellus present. Antenna filiform, sparsely ciliate, scape without pecten. Proboscis developed. Labial palpus ( Figs 2-3 ) recurved, second segment thickened with appressed scales, third segment stouter and distinctly longer than second in male; third segment porrect and slender in female. Maxillary palpus short, filiform. Forewing broad lanceolate, with a large distal patch occupying more than 1/6 of wing, a wavy black line edged along its costal and outer margins and slightly incurved at veins. Hindwing broad, subtrapezoid, anal region well-developed, termen obviously concave beneath apex. Venation ( Fig. 4 ): Forewing with Sc to 1/2 of costa; R4 and R5 long stalked, R3 stalked with R4+5, R5 to termen; M1 and M2 nearly parallel, M2 approximated to M3 at base, M3 and CuA2 from lower angle of cell; CuA1 absent; 1A+2A furcated basally. Hindwing with Sc+R1 to 3/4 of costa; Rs and M1 stalked, M3 and CuA1 from lower angle of cell; 1A+2A furcated basally. Cubital pecten absent.

Male genitalia. Uncus broad, constricted near base, usually triangular or trapeziform distally. Gnathos with pecten of dense spines anteriorly, with narrowly banded lateral arms. Tegumen broad, branched anteriorly. Valva elongate. Sacculus well developed, usually pointed apically. Juxta broad, weakly sclerotized. Vinculum narrow, broad U shaped. Saccus ill-defined. Phallus short, tubular.

Female genitalia. Apophyses anteriores furcate basally. Antrum weakly sclerotized. Ductus bursae membranous, shorter than corpus bursae. Corpus bursae elongate, with granules on inner surface posteriorly.

Remarks. Members of Aulidiotis are much similar in the wing shape, color and pattern, and they are hardly distinguishable superficially except a few species with a discal spot on the forewing. The diagnostic characters include mainly the shape of the uncus, the sacculus, and the valva of the male genitalia.
