Etymology: The species name is a noun in apposition derived from Madagascar.

Diagnosis: The species is recognized by a combination of long spiniform setae with acute tips on the abdomen, a single broad central stripe on the carapace, short strong setae on tibiae and metatarsi I and II ( Fig. 8 View Figs 1–9 ), and only four setae on the anterior edge of the clypeus. The male palp is distinguished by the angular shape of the cymbium, which is extended into a blunt extension laterally, the shape of the embolus, a broad flat ITA and a ventral tooth-like lobe on the RTA ( Figs 35, 36 View Figs 30–36 ). Female unknown.
