Notes. (1) The genus-group names Tegulata and Corcura were introduced in the same publication on the same page ( Walker 1862). As the type species of these taxa display no fundamental differences, one of those genus-group names should be synonymised with another one. Acting as the First Revisers (see Article 24.2 of ICZN (1999)), we herein determine the priority of Tegulata over Corcura . (2) The subgenus is under revision by Volynkin & Černý (in prep.).

Diagnosis. Species of the genus ( Figs 15–18 ) have forewing shape similar to the nominate subspecies with brown ground colour and one or two black spots at the costal margin proximally and/or medially. The male genitalia of Teulisna (Tegulata) ( Figs 100, 101 ) differ from other subgenera in the lack of the distinct border between the basis valvae and the base of the sacculus whereas in other subgenera of Teulisna , the basis valvae is framed by the jugum basalis and is flexibly articulated with the sacculus. Besides this feature, the male genitalia ground plan of Teulisna (Tegulata) is similar to Teulisna s. str. but the former differs in the narrower lamella centralis, which bears a weakly sclerotised and lobular pseudoampulla and almost reaches the dorsal margin of the valva (similar to Cossa ; whereas in the of Teulisna s. str. is bilobate and bears a sclerotised thorn-shaped or clavate pseudoampulla), the thin, string-shaped caulis (vs. broad plate-like one in both Teulisna s. str. and Cossa ), and the broader sacculus with a larger dorsal branch of its distal process. The female genitalia of the subgenus ( Figs 151, 152 ) display no fundamental differences from other subgenera.
