Differential
diagnosis:
the colour pattern of
A. laticlavius
is unique for
Alluviobolus
and also for millipedes living in Petriky, allowing a secure identification of this species.
A. laticlavius
differs from
A. antanosy
sp. n.
in the shape of posterior gonopods and male coxal processes, although the latter species can be found just five kilometers south of Petriky. The posterior gonopods of
Alluviobolus laticlavius
are quite similar to those of
A. tsimelahy
sp. n.
A. laticlavius
, however, differs from the latter in the shape of the male coxal processes as well as in the colour pattern.
Description
.
holotype
with 47 body rings,
39 mm
long,
3.9 mm
wide.
Coloration
on mesozonites faded to grey, metazonites black (
Fig. 44C
). Rings dorsally with a wide red stripe. Legs, antennae, anal valves, subanal scale and posterior part of preanal process faded to light brown (
Figs 44
A–C).
Eyes
with circa 25 ocelli arranged in five rows (
Fig. 44A
).
Antennae
protruding back to ring 5 (
Fig. 44A
).
Male coxal processes
only present on coxae 3 and 4 (
Fig. 57B
). Processes slen- der, bended posteriorly and protruding above coxa of adjacent leg.
Preanal process
absent (
Fig. 44C
).
Anterior gonopod
sternite elevated into a wide lobe, apically slightly tapering. Tip well-rounded (
Fig. 44E
). Coxite and telopodite inconspicuous (
Figs 44E, G
).
Posterior gonopods
: telopodite without a membranous fringe (
Fig. 44H
). Apical sclerite (
x
in
Fig. 44H
) slender, triangular, regularly protruding into a slender, acute tip (
Fig. 44F
).
Distribution
and ecology
: this species is only known and possibly microendemic to the worldwide unique (
Vincelette et al. 2003
) subhumid littoral forest of Petriky (
Fig. 43
). Like other species of the genus, does
A. laticlavius
lives on and in the leaf litter.
Etymology
:
laticlavius
, adjective, refers to the characteristic wide red stripe of this species.
