TYPE: Male holotype, female allotype, male paratype, and 3 female paratypes from sifted leaf litter at P.N. Ranomafana, 2.3 km N Vohiparara, 21 ° 12.89S, 47 ° 23.09E, 1100 m, Fianarantsoa Province, Madagascar (28 Apr 1998, C. Griswold, D. Ubick), deposited in CAS (CASENT 9029655, PBI _ OON 03078 View Materials ).

ETYMOLOGY: The species is named after the type locality.

DIAGNOSIS: The male of this species differs from other Malagiella   by the combination of small size and the absence of lateral spines on the hind legs. The female differs from others in its species group in having a widely sinuous receptaculum, W/L 5 1.0– 1.2 (figs. 182–184, 375–378; map 4).
