"Chelicerae above and laterally duaky over yellow with a
dark line along each side above and a middorsal dark line, ventrally
yellow; fingers rufous proximalIy, dark or blackish distally.
Cephalotborax duaky over a yellow ground., with the color deeper, more
soIid, over the anterior and lateral borders, and a dark line running
from the dark border at eaeh antero-lateral oorner mesocaudad to a median
longitudinal pale line. Eye tubercle black, not divided by a
longitudinaI pale line. Abdomen pale yellow
to dark grayish yelIow excepting a stripe on each side above the
longitudinal furrow composed of a series of dark, ohocolate-brown spots,
the color of the latter not at all extending below the furrow. Femur of
pedipalps yellow, more or less darkened distally; tibia, metatarsus and
tarsus abruptly darker, dusky to nearly black. First and second legs
yellow. Third legs with femur dusky or brown., yellow beneath at
proximal end; tibia dusky or brown, yel1owish at distal end; metatansus
aIao brown, yellow at distal end. The fourth leg with femur darker
brown, yellow proximally beneath; tibia more blackish, yellow at both
ends but the distaJ yellow annulus the larger; metatarsus also dark with
a yellow annulus at each end. The anterior end of cephalothorax
semicircular as usual. Eyes between one-half and three-fourths
their diameter apart. Eye-tubercle in front. with a number of spines of
which two are 1onger and stouter than the others. Metatanrus of
pedipaJp aJong each edge beneath with a. seriee of five stout and
moderately long splnes between which and over ventral surfaoe generally
are numerous cylindrical setae in part of equal and in part of greater
length than the spinee, with fewer very long, fine-tipped. forms. Tibia
with cylindrical setae beneath on distal half. Upper finger
of chelicerae bearing beneath three large teeth on the anterior base of
the most caudal of which is a.much smaller tooth or dentiole. the three
major teeth being followed by three or four small teeth; this finger
along dorsal edge with a ridge which is highest opposite the third, or
caudal, large tooth. Lower finger having typically two Iarge teeth with
a denticle between them.
Length, exclusive of chelicerae., 16 mm."
Chamberlin (1919), in introducing his formal description of this species
states, "In general. structure and
appearance the form resembles Ammotrecha cubae (Lucas); but, aside
from differences in coloration, such as the darker color of chelicerae,
cephalothorax and third legs, it differs in the armature of the pedipalpa,
the metatarsus bearing along each inferior edge a series of five spines
instead of four, with numerous cylindrical setae intervening instead of
these being absent. It also differs in the more pronounced ridge on the
upper finger of the chelicerae above. It differs similarly from the South
American A. geniculata (C. L.
Koch). It approaches the Central American A. stolli (Pocock);
but the tibia of the pedipaJps bears cylindrical setae beneath (female)
instead of their being absent, the eyes are more widely separnted, the
ocular tubercle lacks the median pale stripe, the abdomen is not colored
below the longitudinal furrow on each side, etc."
