Malgassesia opalimargo (Le Cerf, 1913) (Sesia)

Sesia opalimargo Le Cerf, 1913: 167 .

Tipulamima opalimargo Hampson, 1919: 56; Dalla Torre & Strand 1925: 6; Gaede 1929: 519; Viette 1957: 92, 1982: 18; Heppner & Duckworth 1981: 41; Pühringer & Kallies 2004: 33; Bartsch 2018: 174.

Type material examined. Lectotype ♀, designated by Viette 1982: 18: Madagascar, foret d'Ambre; with labels: “Fêt d’Ambre / Madagascar”; “Sesia / opalimargo / Le Cerf / Type”; “HOLOTYPE”; “Sesia / opalimargo / Le Cerf / Bull. Soc. entom. Fr., / 1913, p. 167” . Paralectotype ♀, same data (MNHN) .

Exclusion of this species from Tipulamima is justified by the simple, non-elongate, hindlegs, the only distally somewhat rough scales of the tibia and the between first and second segment slightly constricted abdomen. Furthermore, the distally concave external transparent area and the therefore proximally rounded apical area would be very unusual within Tipulamima .
