Figures 14, 15 
Type. Female from Putre, Province Tarapaca, Chile, Feb. 1948 
(Aviles), in the Museum of Comparative Zoology. The species is 
named after Miss H. Zapfe of Santiago de Chile. 
Description. Carapace dark yellow, darker around anterior median 
eyes. Chelicerae red-brown. Sternum, legs dark yellow. Abdomen 
gray with darker gray mottled pattern on dorsum and a pair of 
longitudinal lighter bands between genitalic area and spinnerets. 
Anterior median eyes slightly smaller than others. Anterior lateral 
eyes on slight tubercles. Anterior median eyes slightly less than one 
diameter apart, a little more than one diameter from laterals. 
Posterior median eyes three-quarters diameter apart, two diameters 
from laterals. Chelicerae with three teeth on anterior margin, a blunt 
indistinct tooth posterior. Total length 9.2 mm. Carapace 4.5 mm 
long, 3.4 mm wide. First femur, 4.1 mm; patella and tibia, 5.0 mm; 
metatarsus, 3.4 mm ; tarsus, 1.6 mm. Second patella and tibia, 4.3 mm; 
third, 3.7 mm; fourth, 5.1 mm. 
Diagnosis. This large species of Enoplognatha can be separated 
from E. juninensis by the lack of posterior lip in the opening of the 
depression of the epigynum (Fig. 15) and by lack of the internal 
coiled duct. The ducts of E. zapfei are heavily sclerotized adjacent 
to the seminal receptacles (Fig. 14). 
Steatoda Sundevall 
Steatoda Sundevall, 1833, Conspectus Arachnidum, p. 16. Type species desig- 
nated by Thorell, 1869, On European Spiders, p. 93. S. castanea (Clerck, 
1757). 
Diagnosis. Medium-sized to large theridiid spiders, usually dark 
in coloration. Colulus very large. Chelicerae armed with a tooth 
or several teeth on anterior margin. But unlike Enoplognatha , it 
has no teeth on the posterior margin of female chelicerae. Abdomen 
subspherical. Males often with enlarged chelicerae and a sclerotized 
ring around pedicel on anterior end of abdomen. The abdomen of 
most species has a white line around anterior of dorsum, in addition 
to other lines or spots (Levi and Levi, 1962).
