Berotha baminana Yang & Liu, 1999: 100 . Type locality: China (Fujian: Shuikou ).

Diagnosis. This species is characterized by the male tergum 9 + ectoprocts rounded distally, the sternum 9 in lateral view distinctly tapering posteriad, the complex of fused gonocoxites, gonapophyses and gonostyli 10 with distinct bristle-bow, reaching to segment 8 anteriorly.

Description. Male. Body length 7.0 mm; forewing length 11.5 mm, hindwing length 10.0 mm.

Head generally yellowish brown with dark brown spots and yellow setae. Compound eyes blackish brown. Antennae yellow with yellowish setae; scape slightly darker, with brown spots on distal margin, and with brownish setae ventrally, length-width ratio approximately 4:1.

Prothorax generally yellowish brown with dark brown spots, setae yellow dorsally but dark brown ventrally; pronotum with dense blackish brown spots laterally, and with one black longitudinal marking medially. Mesothorax yellowish brown dorsally, metathorax brown. Legs yellow with dark brown spots and brown setae. Forewing falcate on apex, slightly smoky brown, but darker along distal margin, with brown spots on branching points of longitudinal veins; pterostigma narrowly elongate, reddish brown, with hyaline parts at middle. Longitudinal veins pale yellow, interrupted by many brownish spots; crossveins brown. Hindwing slightly paler than forewing, immaculate.

Abdomen brown with pale yellow setae.

Male genitalia. Tergum 9 + ectoprocts broad, rounded distally. Sternum 9 in lateral view tapering posteriad, subtriangular. Complex of fused gonocoxites, gonapophyses and gonostyli 10 (= paramere-mediuncus complex) forming a short bow formed by bundled bristles, reaching to segment 8 anteriorly. Hypandrium internum small, subtriangular.

Female. Body length 6.0 mm; forewing length 11.0 mm, hindwing length 10.2 mm.

Female genitalia. Hypocaudae almost twice as long as basal part of gonocoxites 9. Bursa-copulatrixspermatheca complex comprising a small but strongly sclerotized ball-shaped element and a basal coil with varing lumens in width.

Materials examined. Holotype ♂, China: Fujian, Dehua, Shuikou [25°70.060'N, 118°45.242'E], 6.XI.1974, Chikun Yang ( CAU) . Paratype ♀, same data as holotype ( CAU) .

Distribution. China (Fujian).

Remarks. The genitalia of both male and female type specimens are lost. No additional specimens of this species were available for our study. The above description was made according to the remaining parts of the type specimens and the original description in Yang & Liu (1999).
