Male Dorsum of abdomen heavily pigmented, with
light hastate area and indications of paired light spots. Coxae and endites light amber ,
unpigmented ; labium and venter lightly pigmented ; sternum light with marginal blotche s
of pigment. Anterior eye row narrower than the posterior median row, almost straight ;
anterior median eyes twice as large as laterals, closer to laterals than to each other .
Clypeus about as high as the diameter of an anterior median eye . Lower margin of the furrow of the chelicerae with three unequal teeth, middle tooth the largest and closer t o
the lateral, which is the smallest, than to the median .
The median apophysis of the palpus of P. sylvanus somewhat resembles that of P.
apacheanus, both in shape and in having a light-colored tip . The palpus of P. sylvanus is
distinguished by the presence of a straight-edged shelf-like structure proximad of the bas e
of the median apophysis (Fig. 235).
Legs 4123, femora faintly banded . Tibiae I with eight ventral and lateral spines, the
four proximal spines long, overlapping and ventral in position ; the distal pair is apical i n
position. Tibiae II with eight ventral and lateral spines ; the ventral prolateral spines ar e
reduced almost to bristles; the distal pair of spines are apical in position .
Description of female .—From Cove Creek, Washington Co ., Arkansas, V-10-61, No .
L-70. Carapace 2 .60 mm long, 1 .80 mm wide, with a distinct submarginal light band, an d
tuning-fork pattern. Dorsum heavily pigmented, with a narrow light hastate mark an d
four pairs of spots covered with white scales. Ventral surface yellowish amber except for
scattered pigment in the center of the venter and narrow streaks of pigment along th e
edge of the sternum. Anterior eye row narrower than the median row, slightly procurved ;
anterior median eyes twice as large as laterals, somewhat closer to laterals than to eac h
other . Clypeus height equals a diameter of an anterior median eye . Lower margin of the
furrow of the chelicerae with three almost equally spaced teeth, the middle tooth th e
largest, the other two almost equal in size .
The epigynum of P. sylvanus is unlike that of any other Pirata that we have examined
(Fig. 236-237). Legs 4123, very faintly pigmented ; the femora have a suggestion of
annulations. Tibiae I with five long overlapping ventrolateral spines ; distal apical spines
not developed . Tibiae II with four ventral spines and one spine lateral in position, th e
proximal retrolateral spines longer than the prolaterals ; distal spines not developed . |
