Donacaula forficellus: Speidel, 2005 . Pyraloidea I, Microlepidoptera of Europe, 4: 120.

Description. Forewing yellow, a fuscous band along the upper margin of cell, from the base to apex; a fuscous spot at lower angle of cell; apex blunt in male and sharply pointed in female. In male genitalia, subteguminal process lobe-like; juxta nearly pyriform, with apex raised.

Material examined. IZCAS: Heilongjiang, Yichun, Dailing , 1♀, 12 November 1963 .

Distribution. China (Heilongjiang); Europe.

Remarks. The species is similar to D. mucronella , which mainly distributes from north Europe to Northern Asia. D. forficellus has a black spot at lower angle of cell and R 2 free from R 3+4 on forewing, while D. mucronella has spot absent and R 2, R 3 and R 4 stalked. In female genitalia, ductus bursae of D. forficellus is little longer than that in D. mucronella ( Speidel, 2005) .

Additionally, Wang (1980) wrongly inentified Schoenobius scirpus sp.nov. as D. forficellus (see Schoenobius scirpus ).
