Type material. Holotype male ( CASENT9006044 ) from montane rainforest at 1000m elevation in Parc National Montagne d’Ambre , Antsiranana Province, Madagascar, collected 21–30 November 1993 by Jonathan Coddington, deposited in the USNM . Paratypes, two females ( CASENT9006045 ), also from Parc National Montagne d’Ambre , Antsiranana Province, Madagascar, collected 12 August 1992 by Vince and Barbara Roth, deposited in CAS .

Etymology. The species epithet, Salegy, is a popular music genre from Madagascar that has its home in the north of Madagascar; a noun in apposition.

Diagnosis. Uduba salegy are members of Group I.a, the Uduba dahli group ( Map 13 ) of Group I, the Epigynal atrium group. They are cribellate, with large, divided cribellum or vestige. Males can be distinguished from those of other Uduba with a screw-shaped TA3 by having the TA3 J-shaped and extending apicad of TA2, MA small, simple ( Figs. 60 A–C ). The females can be distinguished from those of other Uduba of the of Group I, the Epigynal atrium group, which have an epigynal plate with the median lobe surrounded by a depressed atrium, by having the median lobe end well anteriad of epigastric furrow, with the posterior margin of atrium entire, forming a posterior pocket ( Fig. 74 A ).

Natural history. This species, Uduba salegy , is only known from montane rainforest where individuals were collected in pitfall traps and under objects. We know nothing of its use of cribellate silk.

Distribution. Uduba salegy are known only from rainforests at Montagne d’Ambre in far northern Madagascar (Maps 2, 13).
