Type material. Holotype male ( CASENT9006024 ) from forest at 1000m elevation at Parc National Périnet , near Andasibe, Toamasina Province, Madagascar, collected 4-5 November 1993 by C. Griswold, deposited in CAS.
Etymology. The species epithet is a patronym in honor of the Malagasy musician Rakotozafy, a legendary player of his own customized marovany zither and one of the most celebrated valiha players of the twentieth century.
Diagnosis. Uduba rakotozafy belong to Group V, the Uduba rajery group ( Map 19 View MAP ). Males can be distinguished from those of other Uduba by the form of the male palp, with a thick, swollen VTA on the tibia, the spine-like TA3 extending through a notch at the apex of the tegulum ( Fig. 29 G View FIGURE ), and the large, triangular MA ( Figs. 58 A–C View FIGURE ). Uduba rakotozafy may be distinguished from U. rajery by having the MA apex with an apical lobe and spike ( U. rajery has two spikes, Figs. 55 B View FIGURE , 56 E View FIGURE ). Females are unknown.

Female: Unknown.
Variation. Male. Variation unknown: Uduba rakotozafy is only known from one male, the holotype.
M aterial examined. MADAGASCAR: Toamasina Province: Parc National Périnet, near Andasibe , 18°56ʹS, 48°24ʹE, elev. 1000m, 4–5 November 1993, J. Coddington, N. Scharff, S. Larcher, C. Griswold, R. Andriamasimanana (Holotype, CASENT9006024 , 1♂, CAS) .
Natural history. The lone specimen of Uduba rakotozafy was collected on the ground in rainforest. The vestige of a divided cribellum on the male suggests that U. rakotozafy females deploy cribellate sticky silk, but we know nothing of their behavior.
Distribution. The species Uduba rakotozafy is known only from the type locality at Parc National Périnet in the central eastern escarpment of Madagascar ( Maps 9 View MAP , 19 View MAP ).
