( Figs. 4–5 , 11–12 , 16–17 )

Adapterops nasalis Frieser, 2010: 18 .

Type locality. East Madagascar, Massif Ambondrombe, 1300–1400 m a.s.l. Holotype in ZSMC.

Type material examined. PARATYPE: 1 ♀, MADAGASCAR: FIANARANTSOA: ‘Madagascar Est / 1300-1400 m / Massiv [sic!] Ambondrombe / J. Janák + P. Moravec lgt. // 1 km ouest de la cote 1579 / 14.iii.1996 forêt humide / arbres, arbustes, camp 4’ [p] // PARA- / TYPE [red label, p] // Adapterops / nasalis sp. n. / Paratypus [h] / det. R. Frieser 2009 [p] ( MTDC).

Additional material examined. 1 J, MADAGASCAR: ANTANANARIVO: ‘MADAGASCAR 2011 / AMBOHITANTELY Spec. Res. / S 18°11’51’’ ; E 47°17’03’’ / 1530 m, 24.-29.xi. / M. Trýzna lgt.’ ( MTDC) .

Note on sexual dimorphism. Male ( Fig. 4 ) differs from female ( Fig. 5 ) in narrower head, different shape of dorsal margin of scrobe ( Figs. 11–12 ) and in larger eyes (ocular index 1.00 in male, 1.23 in female). Ventrites I–V in male strongly depressed along midline.

Habitat. The species is hitherto known from two females found in wet primary forest (type specimens) in east Madagascar, Ambondrombe Massif, 1300–1400 m a.s.l. ( Fig. 7 ) and collected by beating trees and shrubs, and a single male from central Madagascar, Ambohitantely Special Reserve, collected by beating lower thin and dry branches of deciduous trees and bushes in secondary forest.
