Description

Length of male 7.5 mm, female 8.8 mm. Dorsum bright yellow except anterior margin of crown and lateral margin of pronotum white. Crown approximately as long as pronotum, anterior margin parabolic. Hind tibial rows PD, AD and AV with 18–19, 13–14 and 11–12 macrosetae, respectively. Style apophysis densely denticulate ventrally, broadened to distal two thirds in lateral view, then gradually narrowed, abruptly curved dorsad and tapered to acute apex. Connective anterior margin truncate. Aedeagus with shaft symmetrical, relatively short, curved dorsad, with pair of angulate lateroapical flanges, gonopore apical on posterior surface; basal process arising from ventral end of atrium, well separated from shaft, extended posteroventrad for short distance, then bent at right angle and extended posterodorsad, distal part asymmetrically twisted and blade-like, apex acuminate. Female abdominal sternite VII with posterior margin weakly trilobed. Second valvulae strongly and evenly broadened from base to near midlength; dorsal margin rising to bluntly angulate peak, then descending evenly to acute apex, distal third finely serrate with teeth slightly offset between sides.

Remarks

The males from Antananarivo Province and Réserve dʼAnkoririka (Majajanga) are excluded from the type series because they exhibit variation in the aedeagus that may eventually prove to be interspecific. The former has the aedeagus with the shaft slightly longer and more slender than that of the holotype, with the apex constricted distad of the lateroapical processes in posterior view and the basal appendage broadened preapically. The latter has the preapical processes of the aedeagus relatively small.
