Description.-
The following description, except for the last paragraph under this
heading, pertains to the males of this species.
Coloration in alcohol purplish brown, chelicerae and
pedipalps paler; dorsal sclerotized parts of exoskeleton darkly mottled,
with membranous areas paler; eye tubercle very dark (Fig. 1); ventral
surface of appendages becoming darker posteriorly, each one paler
proximally; malleoli pale purple, slightly darker distally.
Dentition of chelicerae as in Fig. 2. Movable finger with
principal tooth large, intermediate tooth much smaller, anterior tooth
even smaller (in some individuals anterior tooth only barely
discernible), and mesal tooth missing; distolateral aspect with
cup-shaped slot, subdistally flattened in a vertical plane (Figs. 3 and
4). Fondal notch shallow, vaguely U-shaped, about as wide as base of
fixed finger, with a single, minute denticle; fondal teeth occurring in
two rows, graded laterally I>II >III>IV, and mesally I>III>II>IV; first
lateral fondal tooth large, with small accessory tooth on dorsal side,
fourth mesal fondal tooth minute, but somewhat larger than denticle on
margin of movable finger socket. Fixed finger slightly deflected
distally; groove an indistinct mesoventral hollow becoming
indistinguishable about two-thirds way to base. Flagellum complex, with
apical bristles of dorsal tubular-striate series more distinctly
pronounced apically; apical plumose bristle typical, not conspicuously,
but somewhat, enlarged and flattened.
Eye tubercle located on anterior margin of propeltidium,
with eyes separated by slightly more than one diameter. Propeltidium
wider than long by ratio of 1.4 to 1.
Femur, tibia, metatarsus, and
tarsus of pedipalps sparsely provided with large cylinder bristles,
which become shorter distally. Metatarsus of pedipalps with with scopula
of about 45 large papillae.
First
post-spiracular abdominal sternum provided with two short, stout
ctenidia, whch do not extend quite half way to the posterior margin of
next sternum.
Females differ from males in
the following respects: dentition of fixed finger typical of females of
genus; movable finger of chelicerae much different from that in males,
with larger principal and apical teeth, two smaller intermediate teeth,
and several minute denticules beyond apical tooth; genital operculum
with pair of vaguely triangular plates (Fig. 5).
