Protidricerus steropterus Wang & Yang, 2002: 562 .

Diagnosis. Wing narrow, distal margin and posterior margin of hindwing flat curve or almost straight, CuA2 reaching over 1 cell, forewing axillary angle somewhat projecting. Hind wing distal margin and posterior margin almost straight, CuA2 distinct, Cu area with 2 longitudinal rows of cells, occasional 1 or 2 middle row of cells disconnect each other of cells.

Measurements. Male: body length 29–31 mm, abdomen length 18–19 mm, antenna length 23–25 mm, forewing 34–36 mm, hind wing 29–31 mm. Female: body length 31–33 mm, abdomen length 19–20 mm, antenna length 26–27 mm, forewing 42 mm, hind wing 36–37 mm.

Head. Vertex black, with white and black brown long hairs. Frons and genae black, with white long hairs. Clypeus and labrum yellowish brown. Mandible brown with dark brown apex. Maxillary palpus and labial palpus yellow with darker terminal. Eyes entire, no transverse furrow. Antennae yellowish brown, about 2/3 length of forewing.

Thorax. Dorsum black, with black long setae. Mesoscutellum posterior margin with a row of white long setae. Metathorax with white and black long setae. Venter black, with dense white long setae.

Wings. Forewing hyaline, very long and narrow. The distal and posterior edge almost as a straight line, about parallel to the anterior margin. Axillary angle blunt, protruding. Veins brown. Pterostigma yellowish brown, with 3–4 crossveins. Costal area with 30–31 crossveins, apical area with 3 rows of cells, Cubital area with 4–5 rows of cells the longest central across row. Hind wing shorter and narrower than forewing. Pterostigma yellowish brown, with 3–4 crossveins. Apical area with 3 rows of cells, Cu area with 2 longitudinal rows of cells. CuA2 short, reaching over one cell.

Legs. Red brown. Femora with white long setae, tibia with black long setae. Tarsomere black. Spurs and claws with red brown terminal.

Abdomen. Shorter than hind wing, black. Occasionally lateral margin of some segments with yellow spots.

Terminalia and Genitalia. Male ( Figs. 21–22 ). Ectoprocts oval; gonarcus wide vaulted; parameres close to each other terminal and far separated basal, pelta present; pulvini weakly sclerotized. Female ( Figs. 24–25 ). Ventrovalvae triangular, interdens present; linguella small; distivalvae nearly oval.
