Schoenobius Duponchel, 1836 View in CoL . Hist. Nat. Lepid. Fr., 10: 8, 22. Type species: Tinea gigantella Denis & Schiffermüller, 1775 View in CoL , by original designation (cited as gigantellus , a mandatory emendation).

Diagnosis. The genus is different from other genera by long labial palpi in adults and juxta with raised apex in male genitalia.

Description. Head with frons round; antennae weakly serrated in male and filiform in female; labial palpi porrect, longer than 3 times of the diameter of compound eyes, the second segment longer than other two; maxillary palpi expanded apically. Female with anal tuft on the seventh abdominal segment.

Wings ( Fig. 2 View Figs 1–6 ). Wing patterns simple, some groups polymorphic. Forewing with R 1 close to Sc; R 2, R 3+4 and R 5 from upper angle of cell; R 3 and R 4 stalked; M 1 below upper angle of cell; M 2 and M 3 from lower angle of cell; Cu 1 and Cu 2 before lower angle of cell; CuP present at distal area. Hindwing with Sc+R 1 and Rs shortly stalked, more or less stalked with M 1 at base; M 2, M 3 and Cu 1 close basally; Cu 2 before lower angle of cell.

Male genitalia. Uncus and gnathos simple, beak-like, without any armature; tegumen with sclerotized dorsal ridge usually X-shaped; subteguminal process various, papilliform, fingerlike or hook-like; valva simple, approximately rectangular, distal truncated; juxta with apex raised; saccus usually round; coremata present; aedeagus elongate, vesica with coarse spinules, a slender irregular spine present, manica with minute spinules; ductus ejaculatorius from little above the middle of aedeagus.

Female genitalia. Anal papillae broad, with long setae; apophyses anterioris and posterioris well developed; ostium bursae broad, usually wrinkled; ductus bursae membranous, no longer than corpus bursae; corpus bursae round, membranous.

Distribution. Oriental, Palaearctic and Australia Regions.

Remarks. The genus has 35 species reported. Five species are reported in China here, including one species as new to science and one species unnamed.

Male and female similarly sized, wing span usually 16–23 mm; both wings without obvious fasciae................................................. 2 Male and female quite differently sized, wing span 16–27 mm in male, 23–42 mm in female; both wings with obvious fasciae or spots ..................................................................................................................................................................................................... 3

S. micralis Forewing pale yellow; hindwing pure white, without other tinge ................................................................................................. S. sp.
