Material studied: CE Madagascar : 1 ♂ , 1 ♀ , Andasibe N. P. , Aventure trail, -18.9356 / 48.4154 , ~ 1000 m , 05.04.2019 , rainforest, from vegetation, leg. M. Wanat ( MNHW ) . Aedeagus ( Figs 10−12 ) relatively slender; AeL 0.73 mm ; median lobe drop-shaped, broadest near basal third and strongly, almost evenly narrowing toward rounded and slightly asymmetrical apex, endophallus in ventral view ( Fig. 12 ) with two symmetrical pairs of darkly sclerotized, overlapping structures; proximal pair strongly divergent toward base of aedeagus and composed of subtriangular sclerites, distal pair divergent toward apex of aedeagus, distally each of its sclerites bifurcate; parameres slender, each with 5–6 apical and subapical setae. Remarks. This species was previously known from a single female; the newly found male does not differ from female in external structures and is externally indistinguishable from the holotype (seen as a high-resolution photograph with a scale bar). The holotype was collected in Fampanambo, near the northern tip of the island; the new finding extends the distribution of this species over 400 km SW, to the central-eastern region of Madagascar .
