Rhipidia (Eurhipidia) garrula (Alexander, 1933)

( Figs. 4–8 )

Limonia (Rhipidia) garrula Alexander, 1933a: 140 . Type locality: Mt. Omei, Sichuan ( China).

Diagnosis. Male antenna with eleven bipectinate flagellomeres. Tarsi snowy white. Wing white with brownish black clouds; Sc1 ending near one-third length of Rs, cell dm open by atrophy of m-m, basal section of CuA1 a short distance distad of fork of M. Lobe of gonostylus with two rostral spines.

Description. Male. Body length 6.0 mm, wing length 6.5 mm.

Head (fig. 5). brown, dusted with grayish white. Antenna (fig. 6) about 15 mm long. Scape and pedicel brown, flagellomeres one to eleven pale yellow with basal enlargements and branches brown, terminal flagellomere brown. Each of flagellomeres one to eleven inclusive with two branches which are the longest at sixth flagellomere and nearly three times as long as corresponding flagellomere; terminal flagellomere longated, exceeding penultimate. Proboscis and palpus brown.

Thorax. (fig. 4) Generally brownish yellow, dusted with grayish white. Mesonotum dark brown. Pleuron brownish yellow without conspicuous stripe. Coxae and trochanters yellow; femora and tibiae yellow to brownish yellow with tips dark; tarsi snowy white except bases of first tarsi. Wing (fig. 7) very pale brown with brownish black areas at tip of R1, milky white areas proximally and distally of these brownish black areas, brown areas at wing tip in cells R2 and R3; veins brownish yellow, darker in clouded areas. Venation: Sc1 ending near one-third length of Rs, Sc2 near origin of Rs; cell dm open by atrophy of m-m; basal section of CuA1 a short distance distad of fork of M. Halter 1.0 mm long, yellow with knob slightly dark.

Abdomen (fig. 4). Tergites and sternites brownish black with posterior parts yellow.

Hypopygium (fig. 8). Posterior margin of tergite nine emarginate. Gonocoxite with a single simple ventromesal lobe. Clasper of gonostylus arched at 2/3 length, suddenly narrowed to apical spine. Lobe of gonostylus large; rostral prolongation small with two slender spines arising from commom tubercle. Paramere with mesoapical angle slender.

Female. Unknown.

Specimens examined. Holotype male (USNM), China: Sichuan, Mt. Omei (2134 m), 1931. VII. 17, Geo. M. Franck. One antenna, one leg, one wing and hypopygium are mounted on a similarly labeled microscope slide. Two mid legs are still attached to the body, and the remaining three legs are absent.

Distribution. China (Sichuan).
