Lubin, Opell, Eberhard, Levi — Uloboridae 
55 
Central Prov., along Brown River, near Port Moresby, collected 29 
April 1980 by Y. D. Lubin. One male and one female paratype 
deposited in the American Museum of Natural History, the remain- 
ing types are deposited in the Museum of Comparative Zoology. 
The specific epithet is a Latin noun in apposition, referring to the 
conical web produced by members of this species. 
Diagnosis. Males and females are distinguished by a carapace 
length of less than 1.00 and 1.30 mm, respectively. Males have a long, 
lobed palpal femoral tubercle, a reduced, flattened median apophy- 
sis, a long, broad conductor, and a blunt median apophysis spur 
(Figs. 16-18). Length of female femur I less than 1.2 carapace length 
rather than 1.4- 1.5 carapace length as in other uloborids. Central 
region of epigynum from which lobes arise about one third rather 
than half as wide as the posterior plate (Figs. 19, 34). 
Description. Female. Total length 2.80-3.40 mm (X = 3.20), 
carapace length 1 .00-1.30 mm (X = 1 .09), maximum carapace width 
0.90-1.00 (X = 0.96), carapace width at PLE’s 0.58-0.64 mm (X = 
0.60), area. All eyes except AME’s surrounded by small black circles 
(Fig. 30). PLE nearer midline than in other Uloborus species. 
Sternum tan. Leg I of most specimens as shown in Fig. 33, but 
nearly black in two dark specimens. Dorsum of femur I of all 
specimens black. Abdomen of most specimens light tan or white. 
Abdomen of two dark specimens with white dorsum, black venter 
and two broad, white lateral stripes extending from anterior apex to 
posterior tips. Epigynum consists of two small, weakly sclerotized 
posterior lobes (Fig. 19) whose combined basal width is one-third 
that of the posterior plate (Fig. 34). An epigynal opening found 
dorsal to each lobe leads to a large, irregular spermatheca from 
whose posterior lateral margin a short fertilization duct extends 
(Fig. 35). 
Male. Total length 2.00-2.20 mm, carapace length 1.00 mm, 
maximum carapace length 0.85 mm, carapace width at PLE’s 0.66 
mm, sternum length 0.56 mm. Carapace and sternum coloration 
similar to that of female except that broad gray streaks extend 
anteriorly from the posterior eyes (Fig. 31). Legs light tan, tibiae 
II-IV with light gray dorsal tip. Femur I with three prolateral, one 
dorsal, central; and one distal, retrolateral macrosetae (Fig. 32).
