Type material. Holotype ( CASENT9007875 ) and paratype females ( CASENT9064777 ) collected from sifted litter in montane rainforest at 1620m elevation in Jardin Botanique at Réserve Spéciale d’Ambohitantely , 18°10ʹ17ʺS , 47°16ʹ55ʺE , Antananarivo Province , Madagascar , collect- ed 17-22 April 2001 by the Fisher-Griswold Arthropod Team , deposited in CAS . Paratypes , three additional females ( CASENT9014779 , CASENT9015002 and CASENT9014798 ), collected by raking tree trunks in montane rainforest at 1574m elevation in Jardin Botanique at Réserve Spéciale d’Ambohitantely, 20 March 2003 by Daniela Andriamalala and Diana Silva, all deposited in CAS . Etymology. The species epithet is an honor to Dr. Daniela Andriamalala, Malagasy arachnologist, expert on jumping spiders ( Salticidae ) and goblin spiders ( Oonopidae ), Lakeside International Scholar at CAS, member of the Fisher-Griswold Arthropod Team and collector of many new and interesting arthropods from Madagascar . Diagnosis. Uduba danielae are members of group VI, the Uduba danielae group (Map 20). Females can be distinguished from those of other Uduba with a divided cribellum by the form of the female genitalia ( Figs. 70 A, B ). Uduba danielae is distinguished from U. jayjay by having the median lobe bell-shaped ( Fig. 70 A ), sides gently curved ( U. jayjay with median lobe trapezoidal, lateral margins strongly convex), copulatory openings at anterior margin of obliquely transverse grooves, origin at 0.26 epigynum length ( U. jayjay [ Fig. 70 C ] with copulatory openings beneath anterior margin of obliquely transverse grooves, origin at 0.48 epigynum length) and the vulva with spermathecal ducts ( Fig. 70 B ) beginning anteromedially and forming z-shaped path, lateral, medial, lateral, to posterior ( U. jayjay [ Fig. 70 F ] with vulva with spermathecal ducts beginning anteromedially, forming gentle outside curve to vulva base, then entering at apex of BS bulb).

Natural history. Specimens of the cribellate spider Uduba danielae were collected in leaf litter and on mossy tree trunks in montane rainforest. At least some individuals occur on vertical substrates. Distribution. Uduba danielae are known only from the type locality in montane rainforest in central Antananarivo Province , Madagascar (Maps 10, 20).
