Material examined

Holotype

MADAGASCAR: ♂, Plateau de l’Imerina, Tananarive, Parc de Tsimbazaza, 1200 m a.s.l., 10 Oct. 1951 (MNHN, gen. prep. 4426). Several specimens are recorded by Viette (1967).

Paratype

MADAGASCAR: 2 ♂♂, same locality and date as holotype (MNHN); 3 ♂♂, same locality as holotype, 8 Nov. 1954, P. Viette leg. (MNHN, gen. prep. 4438).

Description

The description of the external features of the holotype by Viette (1967) was accurate (Fig. 6G–H).

WINGSPAN. 17–20 mm (♂♂) according to Viette (1967); however, only one specimen is preserved in MNHN.

MALE GENITALIA (Fig. 2E, M). (After Viette 1967) Additional description: juxta large, plate-like, base slightly fattened, without sclerotization, with long and widening neck, ending on each side in rounded apex, on both sides tufted with small-sized hairs; aedeagus short, stout, not curved, with two lateral areas adorned with short setae; hand-shaped vesica with tuft of needle-shaped cornutus, pointed obliquely downward.

Bionomics

Biology unknown.

Distribution

Madagascar. Only known from the type locality. The record is from secondary grassland replacing upland and montane forest (Mosaic #18) (White 1983) (Fig. 4), belonging to the Sudanian bioregion (Linder et al. 2012) (Fig. 5).
