Type material. Holotype female ( CASENT9004079 ) collected in montane rainforest at 1300m elevation at 3 km 41°NE Andranomay, 11.5 km 147°SSE Anjozorobe, 18°28ʹ24ʺS, 47°57ʹ36ʺE, Antananarivo Province, Madagascar, collected 5–13 December 2000 by the Fisher-Griswold Arthropod Team [BLF2543] deposited in CAS.

Etymology. The species epithet is an honor to Mr. Jean-Jacques Rafanomezantsoa, sometimes called “JJ”, a Malagasy entomologist, Lakeside International Scholar at the California Academy of Sciences, and principal arachnid collector with the Fisher-Griswold Arthropod Survey of Madagascar (2000–2007). As a rugged and resourceful field biologist and essential member of the Fisher-Griswold Arthropod Team, Jean-Jacques Rafanomezantsoa is collector of many new and interesting arthropods from Madagascar.

Diagnosis. Uduba jayjay 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 C, F ). Uduba jayjay are distinguished from U. danielae by having the median lobe trapezoidal, broader posteriorly ( Fig. 70 C ), lateral margins strongly convex ( U. danielae with median lobe bell-shaped, broader posteriorly, sides gently curved, Fig. 70 A ) and the vulva ( Fig. 70 F ) with spermathecal ducts beginning anteromedially, forming gentle outside curve to vulva base, then entering at apex of BS bulb ( U. danielae with spermathecal ducts beginning anteromedially and forming Z-shaped path, lateral, medial, lateral, to posterior, Fig. 70 B ). Male unknown.
