Figures 42 A–C View FIGURE , Maps 1 View MAP , 13 View MAP .

Type material. Holotype male ( CASENT9032857 ) from rainforest at 1000m elevation in Forêt Ivohibe , 24˚34’08ʺS, 047˚12’14ʺE, Toliara Province, Madagascar, collected 2–4 December 2006 by B. L. Fisher et al., deposited in the CAS.

Etymology. The species epithet, hainteny, refers to a traditional form of Malagasy oral literature and poetry; a noun in apposition.

Diagnosis. Uduba hainteny belong to Group I.a, the Uduba dahli group ( Map 13 View MAP ) of Group I, the Epigynal atrium group. They are ecribellate with a colulus; male palp ( Figs. 42 A–C View FIGURE ) with apex of TA3 a slender, pointed screw, TA2 a large, elongate oval blade, visible behind and beyond TA3, apex rounded; MA simple with small prolateral hook. The species Uduba hainteny is very similar to Uduba ibonia except that the latter has a divided cribellum ( Fig. 20 B View FIGURE ). The large and conspicuous TA2 ( Fig. 41 B View FIGURE ) distinguishes U. hainteny from U. fandroana , which has a small, inconspicuous TA2 ( Figs. 39 A, B View FIGURE ). The small MA distinguishes U. hainteny from U. lamba , which has a large, complex MA ( Figs. 49 B, C View FIGURE ). Female unknown.

Variation. Unknown, only the male holotype of Uduba hainteny is known.

Material examined. MADAGASCAR: Toliara Province: Forêt Ivohibe , 55.0 km N Tolagnaro, 24˚34ʹ08ʺS, 047˚12ʹ14ʺE, elev. 200m, malaise trap, rainforest, 2–4 December 2006, B. L. Fisher et al., [BLF15448] (holotype, CASENT9032857 , 1♂, CAS) .

Natural history. The holotype male of Uduba hainteny was collected in lowland rainforest. Retrieval from a malaise trap reveals that the spiders will climb.

Distribution. The species Uduba hainteny is known only from the type locality in southern Madagascar ( Maps 1 View MAP , 13 View MAP ).
