Type material. Holotype male, CASENT9065679 and paratype female, CASENT9064772 , from montane rainforest at 1385m elevation in Tsinjoarivo Forest , Antananarivo Province, Madagascar, collected 26–29 August 2014 by B. L. Fisher et al., deposited in CAS . Paratypes, four males, same collection data ( CASENT9065707 , CASENT9065595 , CASENT9065602 and CASENT9065698 ), deposited in CAS .

Etymology. The species epithet, hiragasy, refers to a musical tradition in Madagascar, with a daylong celebration of music, dances and performances. According to Wikipedia: “ Hiragasy or hira gasy is a musical tradition in Madagascar, particularly among the Merina ethnic group of the Highland regions around the capital of Antananarivo. It is a day-long spectacle of music, dance, and kabary oratory performed by a troupe or as a competition between two troupes. (Wikipedia, ix-29-2021).” A noun in apposition.

Diagnosis. Uduba hiragasy belong to Group III, the Uduba valiha group ( Map 17 ). They are cribellate with divided cribellum or vestige. Males differ from other species by having a retromedian ridge on the tegulum ( Figs. 44 B, C ), and a deeply bifid MA ( Fig. 28 A ) with the prolateral lobe slender, retrolateral lobe stout; U. hiragasy males differ from those of U. valiha by lacking the short, stout spine retrolateral spine from the palpal tibia ( Fig. 28 A ) (spine present in U. valiha , Fig. 64 C ), by having the TA2 blunt, entire ( Fig. 28 A ) (apically rolled in U. valiha , Fig. 28 B ) and the apex of the MA prolateral lobe slender truncate ( Fig. 28 A ) (rounded in U. valiha , Fig. 28 B ). The females ( Figs. 72 C, D ) lack a median lobe or defined atrium from the epigynum and the vulva with a few, anteroposteriorly oriented, spermathecal loops; can be distinguished from those of similar Uduba ( U. valiha and U. fisheri ) species by having the lateral epigynal margins weakly convex (more convex in U. valiha , Figs. 72 G , 80 H and U . fisheri, Figs. 82 C–F ), with a strong margin along the epigastric furrow (weak in U. valiha , Figs. 72 H , 82 F ) and with the copulatory openings in the posterior part of plate ( Fig. 72 C ) at 0.31 of epigynum length (more anterior in U. fisheri , Fig. 72 E ).

Natural history. The species Uduba hiragasy occurs in montane rainforest. Both male and female specimens were collected in pitfall traps. The female has a developed cribellum and calamistrum, but it is unknown if the species wanders or makes retreats.

Distribution. The species Uduba hiragasy is known only from the type locality in rainforest on the eastern side of the escarpment in east-central Madagascar (Maps 10, 17).
