15–30 December 1982
, A. Newton & M. Thayer (
AMNH
; temporary preparations male: VIW-00002, VIW-00003, female: MJR- 0 1337, VIW-00004).
Paratype
:
female, same data as
holotype
.
Etymology:
The specific name is a noun in apposition taken from the
type
locality.
Diagnosis:
Females can be distinguished by their epigyne having an anterior trapezoidal sclerotized area, leaving the posterior margin of the epigyne mostly unsclerotized (
Fig. 10
c). Males are similar to several other
Coptoprepes
by having a RTA curved, longer than the tibia (
Fig. 10
c), but can be distinguished from them by the truncate tip of the primary conductor and from the similar
C. contulmo
n. sp.
by having a ventrally concave secondary conductor (
Figs. 10
b–f, 23-d–f).
Description:
Male
(
holotype
): Prosoma length 2.07, width 1.55, narrower in front than in the female. Ttibia/metatarsus length: I, 1.43/1.33; II, 1.20/1.32; III, 0.92/1.17; IV, 1.28/1.70. Chelicerae slightly smaller than those of female, with six (right) or seven (left) teeth on retromargin, four on promargin. Sternum length 1.13, width 0.83. Spines: leg

v 2-2
-comb or left r1-2-p1-comb, p and r d1-1-1 or left p d1-1-1-0-1, d 0-p1-2 (left leg seemingly abnormal, not considered for scoring of dataset). Opisthosoma length 2.17, spiracle–epigastrium 1.21, spiracle– spinnerets 0.24. Color in ethanol (
Fig. 8
): As in female, but paler, specimen slightly faded. Palp (
Fig. 10
): Tibia short, width/length 1.58, RTA longer than tibia, curved, compressed. Cymbial conductor wide. Tegulum displaced basally in ventral view, mostly visible in retrolateral view. Sperm duct with conspicuous loop on anterior-dorsal margin. Embolus long, with flat, rounded basal process. Median apophysis wide, truncate, translucent. Primary conductor with canal, ending in truncate sclerotized projection. Secondary conductor ventrally concave, well sclerotized, separated from anterior-dorsal sperm duct loop by a membranous stripe. Paramedian apophysis with prolateral-ventral cusp (pPMA,
Fig. 23
d–f) and a series of several short cusps (rPMA).

-2 plus apical comb, p d1-1-1, r d1-0-1, d 0-2-2. Color in ethanol (
Fig. 9
): Prosoma brown, legs brown, darker distally. Opisthosoma pale brown with dorsal pattern brown, with weakly defined posterior chevrons. Opisthosoma length 2.70, epigastrium–spiracle 1.32, spiracle–spinnerets 0.18. Epigyne: Trapezoidal sclerotized patch, mostly anterior to internal ducts. Lateral lobes separate, posterior half not sclerotized except at the limits with the median field. Median field weakly sclerotized (
