Posterior margin of chelicera with one small tooth (missing on one 
side of one specimen). Total length one female 2.9 mm, another 3.8 
mm. Carapace of the latter 1.5 mm long, 1.2 mm wide. First femur 
1.6 mm; patella and tibia 1.8 mm; metatarsus 1.0 mm; tarsus 0.8 
mm. Second patella and tibia 1.5 mm; third 1.1 mm; fourth 1.8 mm. 
Comments. It is not certain that the male and female described 
here belong together. However, since large collections of spiders 
are available from southern and southeastern Arizona and no speci- 
mens of Enoplognatha have been found, I assume that the distribution 
of Enoplognatha maricopa is north from the type locality, where the 
females were found, a poorly collected area. 
Diagnosis. The palpus differs from other North American species 
in that there is no paracymbium on the margin of the cymbium (Fig. 
4). However, the transparent edge of the cymbium is difficult to see. 
On the mesal side of the bulb is a sclerite, probably part of the conduc- 
tor, which has two projections, one toward the venter and one toward 
the distal end of the palpus (Fig. 3). The female differs from 
Enoplognatha intrepida (S0rensen) in that it has two dark openings 
connected by a black groove; posterior to the groove is a swelling 
having a lighter center (Fig. 2).

pi. 16, figs. 8-11, 2. Female type from Urubamba, 3100 m alt., [Cuzco],

Description. Carapace, sternum, legs red-brown. Abdomen black 
with a dorsal pattern as in Enoplognatha tecta (Keyserling) , (1957a, 
fig. 37). Anterior median eyes two-thirds diameter apart, one 
diameter from; laterals. Posterior median eyes two-thirds diameter 
apart, one and one-half diameters from laterals. Anterior median 
eyes slightly smaller than others. Chelicera with three large teeth 
on anterior margin, the first and third larger than the middle one; 
none on posterior margin of the type. However, another specimen 
seems to have the posterior tooth. Colulus relatively small with two 
setae. Total length of female type 6.5 mm. Carapace 3.6 mm long, 
2.4 mm wide. First femur, 2.7 mm; patella and tibia, 3.4 mm;
