Catagela Walker, 1863 . List Specimens Lipid. Insects Colln Br. Mus., 27: 191. Type species: Catagela adjurella Walker, 1863 , by monotypy.

Diagnosis. The genus is different from other genera by the extremely elongated juxta.

Description. Head with frons round; proboscis reduced; antennae weakly serrated; labial palpi porrect, long, the third segment about half length of the second, with apex pointed; maxillary palpi porrect, about 1/3 as long as labial palpi. Female with anal tuft on the seventh abdominal segment.

Wings ( Fig. 4 ). Wing patterns simple, forewing usually with an oblique line from apex to inner margin. Forewing slender, R 1 before upper angle of cell, not closed to Sc; vein R 2 to R 5 arising from upper angle of cell, R 3 and R 4 stalked; M 1 just below upper angle of cell; M 2 and M 3 closed but well separated, M 3 from lower angle of cell; Cu 1 and Cu 2 before lower angle of cell. Hindwing with Sc+R 1 and Rs long stalked, more or less stalked with M 1 at base; M 2 and M 3 separated, M 3 from lower angle of cell; Cu 1 and Cu 2 before lower angle of cell.

Male genitalia. Uncus and gnathos beak-like, apex pointed; tegumen broad, with sclerotized dorsal ridge X-shaped; base of subteguminal process broader than other genus of the Schoenobiinae ; valva with the same width from base to apex, apex truncated or oblique; vinculum broad; juxta with apex extremely elongated; saccus usually round; coremata present, weakly sclerotized; aedeagus usually with a cornutus, various in different species; ductus ejaculatorius arising from middle of aedeagus.

Female genitalia. Anal papillae broad, covered with long setae; apophyses anterioris and posterioris well developed; ostium bursae broad, wrinkled, dense minute spines present inside; ductus bursae membranous, relatively short, no longer than corpus bursae; ductus seminalis arising below ostium bursae; corpus bursae elongated, membranous.

Distribution. Oriental Region.

Remarks. The genus comprises four species, including two species from China.
