Differential
diagnosis:
see
H. goodmani
for a differentiation between both species. The posterior gonopods with the swollen, well-rounded projection (
w
,
Fig. 60E
) resemble closely those of
H. brachiosauroides
; see above for a separation between these two species.
Description
.
Measurements
: males with 50 or 51 rings, circa
72 mm
long, 5.0–
5.2 mm
wide. Female with 50 rings,
74 mm
long,
5.8 mm
wide.
Coloration:
median part of collum, anterior part of telson and body rings greyish (
Figs 60A, C
). Head dark green. Legs and antennae reddish (
Fig. 60B
). Posterior margin of collum, body rings and telson light brown (
Figs 60A, C
).
Eyes
with 46–48 ocelli (
Fig. 60A
).
Anterior gonopod
sternite basally wide, apically elevated into a wide, well-rounded lobe (
Fig. 60D
). Mesal coxite process wide and only slightly protruding (
Fig. 60D
). Apical process of telopodite large and well-rounded. Retrorse margin slender, widely projecting above telopodite margin (
Fig. 60F
); margin basally of apical process not projecting (
Fig. 60F
).
Posterior gonopods
telopodite bent 90° (
Fig. 60G
). Lateral margin with a thick, swollen, well-rounded projection (
w
,
Fig. 60E
). Apical process (
x
) basally wide, apically tapering (
Fig. 60E
). Membranous lobe (
y
) large and circular (
Fig. 60E
). Projection of sperm canal (
z
) straight, long and slender (
Fig. 60G
).
Distribution
and ecology
: this species could until now only be collected in the Andohahela Mountains north of the Isaka-Ivondro corridor (
Fig. 54
), at
1500–1850 m
elevation. It is currently unknown if this species is restricted to such high elevations.

Etymology:
