Diagnosis:
Males of
Odontopeltis giganteus
differ from all other species of the genus by the curved tip of process B (
Fig. 68
). Process B large, not obscured by solenomere in ventral view (
Fig. 69
). Coxae without spiniform process (
Fig. 68
). Femoral region as wide as prefemoral region, unlike in all other species of
Odontopeltis
.
Redescription: Male (
Holotype
, MZSP 100):
Head red. Body reddish. Paranotal tips and telson yellow. Legs reddish. Paranotal teeth formula: 0-0-0-0-2-1-2-2-3-3- 3-2-3-3-2-2-2-1-0-0. Total length 107. Collum 5.1 long, 15.6 wide. Antennae missing. Genital opening 2.5 long, 4.08 wide. Telson 1.4. Gonopods: macrobristles in an inclined line, close together, distance between them less than half length of a bristle. Prefemoral region 2.5 × longer than femoral region. Process A triangular and long, almost the size of the solenomere, without projections. Solenomere with a median process (arrow, visible in ventral view,
Fig. 69
) and with a hump (arrow, visible in mesal view,
Fig. 68
).
Female:
Body as in male. Paranotal teeth formula: 0-0-0-0-2-2-3-2-3-2-2-3-3-2-2-2-1-1-1. Total length 89. Collum 5.0 long, 14 wide. Telson 2.0. Cyphopod short and oval-shaped, covered by bristles. Ectal valve slightly bigger than mesal valve (
Figs 53
,
71
). Mesal valve subrectangular (mesal view,
Fig. 73
). Ectal valve lozenge-shaped (
Fig. 72
).
