Adapterops festivus Frieser, 2010: 18 .

Type locality. East Madagascar, Moramanga town surroundings. Holotype in ZSMC.

Material examined. MADAGASCAR: TAMATAVE: 1 J 2 ♀♀, ‘ E Madagascar, 2001 / Tamatave distr. / Andasibe (Perinet) / D. Hauck leg., 17.-30.xii.’ ( MTDC) ; 1 J, ‘ Madagascar , 26.xi.2010, / Andasibe-Mantadia N.P., / Analamazaotra forest, // S 18°56´42.4´´, / E 048°25´04.8´´, / 925 m, M. Trýzna leg.’ ( MTDC) .

Note on sexual dimorphism. Female ( Fig. 2 ) generally more robust than male ( Fig. 1 ). Male differs from female also in narrower head, different shape of dorsal margin of scrobe ( Figs. 8–9 ) and in larger eyes (ocular index 1.07 in male, 1.33 in female). Antennal club more robust and wider in female ( Fig. 14 ) than in male ( Fig. 13 ). Ventrites I–V in male strongly depressed in middle.

Habitat. All specimens from the Andasibe-Mantadia NP were captured by beating lower dead branches of deciduous trees in secondary forest at altitude ca. 900– 950 m.
