AMD Transverse diameter of left anterior median eye pupil. 
EGS Number of epiandrous gland spigots. These are located 
just anterior to genital opening on abdomen of adult males. 
CTP Number of cheliceral teeth in prolateral macrotooth row on 
left chelicera. 
CTR Number of cheliceral teeth in retrolateral row of smaller 
macroteeth on left chelicera. 
CMT Number of cheliceral microteeth between these two rows 
on left chelicera. 
PTSP Number of ensiform macrosetae on prolateral surface of 
tarsus of female pedipalp. 
PTSR Number of ensiform macrosetae on retrolateral surface of 
tarsus of female pedipalp. 
IMS Number of ensiform macrosetae on metatarsus of leg I of 
female. 
All measurements and counts were performed by myself with the 
same Wild M-5 stereomicroscope with 20 X eyepieces and an eye- 
piece micrometer scale. The measurements are accurate to one mi- 
crometer unit for each of the three different powers of magnification 
used. One micrometer unit had the following values for the follow- 
ing characters: 0.0770 mm for CL; 0.0385 mm for PCL, CW, SL, 
SW and all leg and pedipalp segment lengths; and 0.0092 mm for 
PTT, PED, PCA, PSS, PSL, and all eye measurements. 
A female specimen was included in a population sample only if it 
was reproductively active (with maturing eggs in abdomen or brood 
in burrow) or had a longer carapace than the smallest reproductively 
active female in that sample. Many first adult instar females, a few 
older adult instar females, and rarely a large immature female make 
up the portion of a sample which is not reproductively active. 
MORPHOLOGICAL TERMINOLOGY 
Setae. Postocular setae form a longitudinal row or longitudinal 
cluster along the median longitudinal axis of the pars cephalica just 
behind the eye group. A macroseta is a very large seta. Called spines 
by many authors, these macrosetae are attached to the exoskeleton 
proper by means of an obvious socket which allows for some move- 
ment. An ensiform macroseta is one which tapers rather abruptly at 
its terminal end and is therefore rigid for its entire length ( Fig. 8 ) . 
An attenuate macroseta tapers gradually and is therefore very slender 
distally (Fig. 9) .
