TYPE LOCALITY.— Madagascar, Fianarantsoa Province, Ranomafana National Park .

DERIVATION OF SPECIES NAME.— The species epithet, ranomafanae , is a noun in apposition, derived from the name of the national park in which the type was collected.

RECOGNITION.— Size average for genus, SBL of males = 7.7–8. 2 mm, of females = 7.8– 8.4 mm. The following combination of features identify members of this species as coelostomine ( Fig. 8B ) relatively broader and with lateral margins slightly straighter in basal one-third (slightly narrower and with lateral margins more evenly rounded ( Fig. 8A ) in D. minimus ); and median lobe of male genitalia ( Fig. 9B ) with apex slightly recurved dorsally in lateral aspect (apex ( Fig. 9A ) nearly straight in D. minimus ), apical part of shaft ( Fig. 9E ) straight (apical part of shaft slightly deflected right ( Fig. 9D ) in D. minimus ).

GEOGRAPHICAL DISTRIBUTION.— At present, known only from the type locality.

HABITAT DISTRIBUTION.— Specimens of this species have been collected in both primary and secondary montane rainforest throughout RNP, at elevations ranging from of 900 to 1180 m. Most of the specimens were collected by beating vegetation, especially plants of Pandanus sp. , and suspended accumulations of dead vegetative debris in shrubs and understory trees. One was collected in a malaise trap, another sifted from forest litter at the primary forest site, and another by hand at the secondary forest site.
