Holotype female from camp 5 at 1875m elevation in Réserve Naturelle Intégrale d’Andohahela (24º33.7ʹS, 46º43.3ʹE), Toliara Province, Madagascar, collected 27 November–5 December 1995 by S. Goodman (SG1995-01) ( CASENT9006074 ), deposited in FMNH . Paratype female ( CASENT9009538 ) from montane rainforest at 900m elevation at Col du Sedro in Parc National d’Andohahela (24°45ʹ50ʺS, 46°45ʹ6ʺE), Toliara Province, Madagascar, collected 21–25 January 2002 by the Fisher-Griswold Arthropod Team, deposited in CAS .

Etymology. The species epithet is a patronym in honor of Steve Goodman, naturalist, author, collector and mammologist who has made substantial contributions to our knowledge of Madagascar biodiversity.

Diagnosis. Uduba goodmani belong to Group II, the Epigynum lateral projection group, or Uduba evanescens group (Map 16). They are ecribellate. Females can be distinguished from those of other Uduba species by the form of the female genitalia ( Figs. 77 A–C . 80 E, F ): epigynal plate a broad oval, width 1.50 times length, lateral lobes with convex edges forming ridges on each side ( Fig. 80 E ); vulva broad, width one and-a-half times length with spermathecal ducts characteristic, forming one and-a-half loose, transverse loops ( Fig. 80 F ), copulatory duct lateral and extending mesally to lead to posterior, widely spaced fertilization ducts. Males are unknown.

Natural history. Collection data suggest that the species Uduba goodmani occurs in montane rain forest.

Distribution. Uduba goodmani are known only from two nearby localities on mountains at Andohahela in far southeastern Madagascar (Maps 6, 16).
