Figs 2 , 7A

Bittacus succinus: Carpenter 1954: 39–40 , figs 3B, 4C.

Diagnosis: Provided by Carpenter (1954).

Redescription:

Male.

Forewing 17 mm long ( Fig. 2B ). Two pterostigmal crossveins, Pcv1, Pcv2; Sc long, ending distally far beyond fork of Rs; sc–r opposite fork of Rs, which is opposite fork of Mb; numerous additional veins in cells r3, r4, r5, r6, m1, m2, m3.

Genitalia ( Figs 2C , 7A ): epiandrial lobe distinctly widened about proximal 1/3, gradually tapering toward apex.

Female. Unknown.

Holotype (examined): MCZ 5204 (= old no. 5112), a fairly intact male, missing some leg parts, clearly preserved on one side, with milky covering on the other.

Remarks: Upon re-examination of the holotype, the wing venation as illustrated by Carpenter (1954, fig. 3B) is in part incorrect, and a revised drawing is provided here ( Fig. 2B ).
