Type material. Holotype male ( CASENT9029870 ) from evergreen forest at 970m elevation in Parc National Ranomafana , 21º15ʹ50.6ʺS, 47º25ʹ9.6ʺE, Fianarantsoa Province, Madagascar, collected 11–12 January 2009, C. Griswold ( CGM01 ), deposited in CAS. Two paratype females ( CASENT9003516 ) and ( CASENT9003517 ), both from mixed tropical forest at 900m elevation in Ranomafana National Park, 21.25041°S, 47.41945°E, collected 2–22 January 2001 by D. H. and K. M. Kavanaugh, R. L. Brett, E. Elsom and F. Vargas, and one paratype male ( CASENT9031127 ) from Talatakely, 1.68 km SW Ranomafana, elev. 970m, 21º15ʹ50.6ʺS, 47º9.6ʺE, collected 11–12 January 2009 by C. Griswold, A. Saucedo and H. Wood, all deposited in CAS.

Etymology. The species epithet is a patronym in honor of Dr. David H. Kavanaugh, Coleoptera curator and natural history explorer from the California Academy of Sciences, who dauntlessly pursued and collected this species as well as other Uduba .

Note. In the phylogeny publication by Wheeler et al. (2017) a voucher specimen of this species was included and listed as Uduba sp. CG301 “big red juvenile” ( Wheeler et al., 2017:fig. 6), DNA voucher, with the following collection data: “Talatakely forest, 42.3 km 58˚ NE Fianarantsoa, S21˚15ʹ28.0ʺ, E47˚25ʹ21.8ʺ, elev. 1050m, montane rainforest, general collecting, 24 December 2005 to 14 January 2006, H. Wood, J. Miller, J.J. Rafanomezantsoa, E. Rajeriarison, V. Andriamananona, [HW009] [DNA-MAD-111] 1j, (CASENT9024063, 1 juvenile, CAS)”.

Diagnosis. Uduba kavanaughi are members of Group I.a, the Uduba dahli group ( Map 13 ) of Group I, the Epigynal atrium group. They are ecribellate and very large, with males greater than 22mm, females greater than 30mm total length. Males can be distinguished from those of other Uduba with a screw shaped TA3 by having the TA2 that is hidden ventrally behind TA3 ( Figs. 47 A–C ) and are distinguished from Uduba platnicki by having the TA2 formed as a small, blunt blade with a median longitudinal ridge ( Fig. 28 F ) (in Uduba platnicki the TA2 a small, simple mound, lacking such a ridge, Fig. 28 E ). Females can be distinguished from those of other ecribellate Uduba that have an epigynal plate with median lobe surrounded by depressed atrium ( Figs. 76 D, E ) by having the plate short or nearly absent posteriad of atrium, height less than 0.12 times epigynal length, lateral lobes meet behind atrium to form short posterior plate, equal to 0.08–0.12 times epigynum length, median lobe short and broad, width atrium less than 3 times ML width, ML length less than 1.50 times width, atrium a broad depression on each side of ML; CO ( Figs. 76 D, E ) appear to be beneath the ML (as in U. halabe , Figs. 74 C, F ), but U. halabe has an entire cribellum ( Fig. 20 A ) whereas U. kavanaughi is ecribellate.

Natural history. The species Uduba kavanaughi has been collected in rainforest. Males and females of this large, ecribellate species have been found wandering at night. David Kavanaugh (pers. Comm.) reports that several females were found in burrows from which they emerged for short distances at night, and into which they quickly retreated when disturbed. These burrows never had any extended turrets or even evident silk atop or in any of these burrows.

Distribution. Specimens of Uduba kavanaughi are known only from the vicinity of Ranomafana Forest, in southeastern Madagascar ( Maps 9 , 13 ).
