Note.

This species was described from a single ♂ holotype, from Nosy Be Islet ( Attems 1898), slide NHMW MY 4429 containing its two legs and gonopods (Fig. 9 C ), labelled Tubercularium odontopezum ( Attems, 1898) , revised, in the NHMW collection. The torso seems to be misplaced.

Brief description.

(After Attems 1898, 1940.) ♂ holotype 28 mm long and 2.0 and 3.5 mm wide on pro- and metazona, respectively. Colouration of metaterga more intense brown in posterior halves, lighter in anterior ones; sides of paraterga yellowish, venter light yellowish brown, antennae and legs dirty yellow. Paraterga horizontal, not upturned above dorsum, sharpened caudally; dorsal tuberculations between paraterga mostly round (Fig. 9 A ).

Gonopods (Fig. 9 B, C ) showing setose femorites (fe), each with a small roundish, pulvillus-like field (p) of particularly dense setae ventrally near apex, coupled with complex acropodites: a slightly sigmoid and apically bifid solenomere (sl) lying between the highest, erect and subspiniform mesal branch (mb) and a much shorter, but prominent, roughly laciniate and fimbriate lateral branch (lb) directed ventrad.
