Figures 8 E, 55 A–C, 56 A–F, Maps 9, 19.  
 Type material. Holotype male (CASENT9026393) from a yellow pan trap in littoral rainforest at 20m elevation in Forêt Ambohidena, Ile Sainte Marie, Toamasina Province, Madagascar, collected 21–24 November 2005 by Brian L. Fisher et al., deposited in CAS.   
 Etymology. The species epithet is patronym is honor of the Malagasy musician Rajery, born Germain Randrianrisoa, who is a player of the bamboo tube zither (valiha) and who founded the modern valiha orchestra. In spite of a childhood accident that cost him the fingers of one hand he developed a unique and memorable style of playing the valiha, invented notation for this instrument, and is one of Madagascar’s finest recording artists.   
  Diagnosis. Uduba rajery  belong to Group V, the Uduba rajery group (Map 19). Males can be distinguished from those of other Uduba by the form of the male palp (Figs. 55 A–C, 56 A–F ), with a thick, swollen VTA on the tibia, the spine-like TA3 extending through a notch at the apex of the tegulum, and the large, triangular MA: Uduba rajery may be distinguished from U. rakotozafy by having the MA apex with two spikes (Figs. 55 C, 56 B, D, E) (U. rakotozafy has an apical lobe and spike, Fig. 58 A). Females of Uduba rajery are unknown.

Leg formula 1423. Male palp: palpal tibia 0.52 times cymbial length, RTA broad, very short, sharply-curved to ventrad (Fig. 55 C), RTA length 0.09 tibia length, length 0.44 times width, VTA unique, large, swollen, transversely wider than long and truncate apically (Figs. 55 B, C, 56 A), length 0.705 times width, length 0.44 tibia width; tibia lacking stout spines; tegulum convex, without ridge, tegulum length 0.98 times width; TA1 serrate medially and with pointed apex, extends distad of tegulum apex, TA1 extends slightly past TA3 apex; TA3 elongate with recurved apex extending through notch at tegular anterior margin (Figs. 56 B, F), TA3 extends apicad of TA2 by 1.25 tegulum length, TA2 a mound partly forming the notch from which the TA3 apex emerges and partially covering mesal margin of MA (Figs. 55 B, 56 B, E); MA origin at 0.26 times tegulum length, MA apex extends distad of tegulum apex, length (including apical processes) 2.00 times width, MA very large, length 0.81 times tegulum length, width 0.395 times tegulum width, oval with a swollen, rounded base and with retrolateral and prolateral acutely-pointed apical projections (Fig. 55 B, 56 D, E); conductor fan entire. Female: Unknown.   
 Variation. Unknown: the species Uduba rajery is only known from one male, the holotype.   
 Material examined. MADAGASCAR: Toamasina Province: Ile Sainte Marie, Forêt Ambohidena, 22.8 km 44°NW Ambodifotatra, 16°49ʹ28ʺS, 49°57ʹ51ʺE, elev. 20m, yellow pan trap, littoral rainforest, 21–24 November 2005, B. L. Fisher et al. [BLF12839] (Holotype, CASENT9026393, 1♂, CAS).   
 Natural history. The lone specimen of Uduba rajery was collected in littoral rainforest. Like all adult male Uduba it was wandering when trapped. The vestige of a divided cribellum on the male suggests that U. rajery females deploy cribellate sticky silk, but we know nothing of their behavior.   
  Distribution. Uduba rajery  is known only from the type locality on Ile Sainte Marie, off the northeast coast of Madagascar (Maps 9, 19).
