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
.)
♂holotype28 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.
