Etymology

The name is that of the nearest city to the type locality.

Type material

Holotype

MADAGASCAR: ♂, mounted on three slides, tributary of the Sahatandra River , near Moramanga, 18°56′27″ S, 48°29′12″ E, 800 m, 28 Apr. 1998, leg. J.-M. Elouard.

Description

SIZE. Forewing 6.4 mm, hind wing 5.0 mm.

TERGUM X. Dorsal branch of the lateral lobe long (twice as long as the ventral branch), basal part straight, proximal part gently curved dorsad (lateral view), a small bump with two sensillae just before the curvature.

INFERIOR APPENDAGE. Triangular with long anterior margin and short ventral margin, dorsal apex slightly curved distad, inner lobe large and rounded (dorsal view).

PHALLIC APPARATUS. Phallotheca strongly angled at base, then gently bent ventrad, distal part (one third of the length) poorly sclerotized with the exception of a dorsal strip with triangular apex (lateral view, Fig. 12D ); internal sclerite as long as the modified distal part of the phallotheca, with enlarged base and curved apex; phallotremal sclerite shorter than the internal sclerite.
