1982] Lubin, Opell, Eberhard, Levi — Uloboridae 53 
Colombian department of Meta; collected 1978 by W. G. Eberhard, 
in the Museum of Comparative Zoology. The specific epithet is a 
Latin noun in apposition, referring to the small size of members of 
this species. 
Description. As most features of this species are presented in the 
genus description, only those of color and size are given here. Total 
length of female 1.92 mm, of males 1.50 mm. Female carapace 0.72 
mm long, male carapace 0.66 mm long. Female sternum 0.44 mm 
long, male sternum 0.38 mm long. Female AME diameter 60 jum, 
male AME diameter 80 ^m, remaining eyes of both sexes 40 pm in 
diameter. Female leg length (I— IV): 2.86, 1.78, 1.52, 2.42 mm. Male 
leg length: 2.70, 1.56, 1.33, 1.94 mm. Female calamistrum composed 
of 10 setae and 0.22 mm long, extending 0.52 the metatarsus length. 
Female cribellum 180 wide, 60 ^m long. Female anterior 
spinnerets 0.30 mm long, male 0.16 mm long. Female posterior 
spinnerets 0.27 long, male 0.18 mm long. Female anal tubercle 0.14 
mm long, male 0.10 mm long. 
Except for dark circles around the eyes (Figs. 21-22) members of 
neither sex have conspicuous color markings. The thoracic groove is 
slightly darker than the rest of the carapace, and white guanine 
deposits under the abdomen’s integument are interrupted by the 
cardiac area which creates a tan median stripe (Figs. 21-22). 
Lacking these deposits, the anterior third of the female’s abdomen is 
also tan rather than white. 
Distribution. Known only from the type locality in eastern 
central Colombia.
