DESCRIPTION. ( Orneodes baihua after Yang, 1977; translated here from Chinese to English). “Body length about 5 mm, wingspan about 11–12 mm, gray brown species. Antenna about 2/3 length of the forewings. Labial palpus with basal two segments grayish white, outside with dark brow sacles, triangular; the terminal segment blackish brown except base grayish white, slender and sharp. Thorax grayish brown. Abdomen with each segment grayish white apically and with three brown spots. Legs grayish white, outer side scattered with brown spots. Forewing grayish brown, densely covered with different-sized spots; cilia also changes with the wing color; costa with a row of five brown spots largest and significant, with white edges on both sides; base of cost with two smaller spots; other five lobes with two brown spots of varying lengths respectively, produced into median fasciae and subterminal fasciae. Hindwing scattered with brown dots, lighter than forewing in color”.

FEMALE GENITALIA. Papillae anales unobvious. Apophyses posteriores nearly equal to Apophyses anteriores in length, slender. Ostium unobvious. Antrum about 1/4 length of apophyses posteriores; basal portion sclerotized; distal portion membranous, sinuate at junction with ductus bursae. Ductus bursae slighty longer than antrum; basal portion about 1/3 of antrum in width, distal portion slightly wider than basal portion. Bursa copulatrix long elliptic, about 1.5 times of apophyses posteriores in length, about 1/4 of length in width; distal 1/4 with an irregularly asteroidal small signum.

REMARKS. Unfortunately, in Beijing Agricultural University in the type series of nine specimens, only one female paratype has been found. Judging by the genital structure of this only paratype found, it can be assumed that it belongs to the genus Pterotopteryx .

DISTRIBUTION. China ( Beijing).
