Fig. 1b

Material examined

MADAGASCAR • 2 ♂♂, 1 ♀; Toliara (Tulear) Distr., Betioky, Beamalo ; 24°08ʹ S, 45°15ʹ E; 21 Feb. 1993; C.C.D. Tingle leg.; NMWC • 6 ♂♂, 8 ♀♀; same collection data as for preceding; 14 Feb. 1993; NMWC .

Remarks

Described from the male sex from Madagascar ( Deeming 1987: 23) and additional material (males only) also from several localities in Madagascar was reported by Deeming (2019).

Female: apart from sexual differences differing from the male in the following respects: all tarsi more or less infuscate; fore femur black on all but basal one fifth of its length and on extreme apex; fore tibia black on all but basal one fifth of its length; tergite 1+2 with a dark median vitta, which is connected to a broad transverse band occupying two thirds of the width of dorsum of tergite 2 and its apical half; tergite 3 with an equally broad trapezoid dark marking having rounded shoulders, which is wider at apex than at base and occupies the entire exposed length of the tergite (in some specimens this marking divided by a pair of longitudinal yellow vittae, but whether divided or not a pair of grey dusted vittae giving it the appearance of being so); tergite 4 with a little narrower but similar marking to that of tergite 3, but this always divided by yellow vittae into a dark median vitta bounded on either side by a triangular spot; tergite 5 with a dark median vitta on basal half and a pair of oblong dark spots level with its apex; tergite 8 ( Fig. 1b ).

Distribution

Madagascar.
