Type material. Holotype male ( CASENT9042524 ) from malaise at 822m elevation in the Miandritsara Forest , 40 Km S of Ambositra, Fianarantsoa Province, Madagascar, collected 25 October–4 November 2006 by R. Harin’Hala and M. Irwin, deposited in CAS . Paratypes, two males, one from Sahamalaza National Park , Antsiranana Province ( CASENT9064667 ) deposited in CAS , and one from Forest des Milua , Toliara Province ( FMNH-INS #-0000-044-065) deposited in FMNH .

Etymology. The species epithet is from the Malagasy word taralily, which is an annual rice harvest festival held on the island of Madagascar; a noun in apposition.

Diagnosis. Uduba taralily are members of Group I.c, the Uduba funerea group ( Map 15 ) of Group I, the Epigynal atrium group. Males can be distinguished from those of other cribellate (with at least vestige of a divided cribellum) Uduba by having the male palp ( Figs. 63 A–C ) with TA2 highly sclerotized, black, concave medially against TA3, MA forked, concave in middle with proximal and distal small pointed projections ( Fig. 63 B ). The forked MA distinguishes Uduba taralily from other divided cribellum males: U. taralily are distinguished from those of U. woodae and U. lehibekokoa by having the MA with proximal and distal small pointed projections ( Fig. 63 B ), tegulum apex at 0.40 tegulum length from MA apex, length (including apical processes) 0.69 times width: U. lehibekokoa ( Figs. 50 A–C ) and U. woodae ( Figs. 66 A–C ) have the MA with only a proximal sharp point, and the MA smaller and farther distad, with the tegulum apex less than 0.35 tegulum length from MA apex, MA length (including apical processes) less than 0.50 times width. The female of Uduba taralily is unknown.

Natural history. Males of Uduba taralily have been collected in various forest habitats from only 50m elevation by pitfalls up to a collection by malaise trap at over 800m elevation. Collection of individuals in pitfalls and malaise traps suggest that males wander on the ground and up into the vegetation. Males have a vestige of a divided cribellum, but we know nothing of the use of cribellate silk by this species.

Distribution. The three widely separated records of this species (Maps 10, 14) suggest that Uduba taralily occurs throughout dry forests west of the mountain spine of Madagascar.
