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 View MAP ). 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 View FIGURE ), and a deeply bifid MA ( Fig. 28 A View FIGURE ) 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 View FIGURE ) (spine present in U. valiha , Fig. 64 C View FIGURE ), by having the TA2 blunt, entire ( Fig. 28 A View FIGURE ) (apically rolled in U. valiha , Fig. 28 B View FIGURE ) and the apex of the MA prolateral lobe slender truncate ( Fig. 28 A View FIGURE ) (rounded in U. valiha , Fig. 28 B View FIGURE ). The females ( Figs. 72 C, D View FIGURE ) 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 View FIGURE , 80 H and U View FIGURE . fisheri, Figs. 82 C–F View FIGURE ), with a strong margin along the epigastric furrow (weak in U. valiha , Figs. 72 H View FIGURE , 82 F View FIGURE ) and with the copulatory openings in the posterior part of plate ( Fig. 72 C View FIGURE ) at 0.31 of epigynum length (more anterior in U. fisheri , Fig. 72 E View FIGURE ).

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).
