Schoenobius sp. ( Figs 65–66 , 74 , 84 )

Description. Wing span ♂ 19–23 mm, ♀ 19–23 mm. Head pale yellow; labial palpi porrect, pale fuscous, 3 times as long as the diameter of compound eyes; maxillary palpi porrect, pale fuscous. Thorax and abdomen pale yellow. Wings without any fasciae. Male with forewing pale yellow, costa little darker; hindwing white. Female with forewing paler than male; hindwing white.

Male genitalia. Uncus short, with base broad and apex pointed; gnathos similar with uncus, apex pointed; tegumen broad, with sclerotized dorsal ridge X-shaped; subteguminal process fingerlike, weakly sclerotized; valva with the same width from base to distal, distal truncated; juxta plate-like, apex raised, with a longitudinal process centrally; saccus round; coremata present; aedeagus slender, a slender irregular spine-like cornutus present.

Female genitalia. Anal papillae broad, with long setae; apophyses anterioris and posterioris well developed, 1.5 times as long as anal papillae; ostium bursae broad, wrinkled; ductus bursae little shorter than the diameter of corpus bursae; ductus seminalis below the ostium bursae; corpus bursae round, membranous.

Material examined. IZCAS: Tianjin, 1♂, 28 May 1952 ; Tianjin, 1♀, 11 July 1959 ; Tianjin, 1♂, 4 June 1963 ; Tianjin, 1♂ , 1982, Lian-Sheng Zhang; Tianjin, Jinghai, Liangwangzhuang , 1♂, 1♀, 25 July–3 August 1959 ; Hebei, Tanghai , 1♂, 22 June 1989 , Su-Bai Liao.

Distribution. China ( Tianjin, Hebei).

Remarks. The species looks similar to S. micralis , by the absence of the fascia on wings. By contrasting with the figures of S. micralis from BMNH, S. sp. has the hindwing white, while S. micralis has the hindwing ochreous. As the difference is minute, it is not suitable to report the species as a new species. As a result, the species is unnamed here.
