1982] Lubin, Ope 1 1, Eberhard, Levi — Uloboridae 57 
Tibia I with eight prolateral, seven dorsal, and three retrolateral 
macrosetae. Sternum and abdominal venter with orange setae. 
Abdomen gray with a pair of thin, white, lateral longitudinal stripes 
running nearly its full length. Palpal femur with a large, lobed 
retrolateral tubercle and a very small prolateral tubercle (Fig. 16). 
Median apophysis bulb small and flattened (Fig. 16); median 
apophysis rectangular with a blunt apex (Figs. 17-18). Conductor 
long and broad, extending from median apophysis spur to area of 
palp adjacent to patella. 
Distribution. Known only from the type localities in Papua New 
Guinea. 
Uloborus albolineatus new species* 
Figures 36-39. 
Type. Female holotype from Lowlands Agricultural Experimental 
Station, Kerevat, East New Britain, Papua New Guinea, collected 6 
July 1980 by Y. D. Lubin, deposited in the Museum of Comparative 
Zoology. The specific epithet is a noun in apposition, referring to 
the species’ white median abdominal stripe. 
Diagnosis. Males are unknown. The female is distinguished by 
having reddish brown median eyes, a very convex sternum (Fig. 37), 
white guanine deposits in the cardiac region (Fig. 36), and weakly 
sclerotized epigynal lobes rising from the center rather than poste- 
rior of a transparent epigynum (Fig. 38). Unlike many Uloborus 
species, the carapace lacks a conspicuous median light stripe. 
Description. Female. Total length 2.40 mm, carapace length 0.92 
mm. maximum carapace width 0.74 mm, carapace width at PLE’s 
0.50 mm. Carapace tan with gray, reticulate lateral markings (Fig. 
36). Median eyes reddish brown. AME’s on a more conspicuous 
tubercle than most Uloborus species. Sternum tan, widest at coxae I 
rather than between coxae I and II as in other Uloborus species. 
Legs light tan with faint gray distal rings on most segments. Tibia I 
with very sparse distal setal brush. Abdomen height and width 0.9 
its length, dorsum with a pair of centrolateral tubercles, posterior 
For nomenclatural purposes, B. D. Opell is author of this species.
