tip projecting slightly posterior to anal tubercle’s base and separated 
from anal tubercle by a distance one third the abdomen’s height. 
White guanine deposits extend both in a narrow transverse band 
across the abdomen’s anterior ventral surface and along the cardiac 
area. A broader, more diffuse median guanine deposit extends from 
the abdomen’s humps to its posterior tip. A pair of large guanine 
spots is found anteriolaterally to the spinnerets. Epigynum convex 
with broad posterior extension, a pair of low, weakly sclerotized 
median lobes, and a transparent integument through which a single 
pair of spherical spermathecae is clearly visible (Figs. 38, 39). 
Distribution. Known only from the type locality in Papua New 
Guinea.

Figures 40-48. 
Types: Female holotype, three male and seven female paratypes 
from Fowlands Agricultural Experimental Station at Kerevat, East 
New Britian Prov., collected 2, 4, and 6 July 1980 by Y. D. Fubin. 
Male and two female paratypes deposited in the American Museum 
of Natural History, remaining types in the Museum of Comparative 
Zoology. The specific epithet is a latin noun in apposition, referring 
to the male’s doubly coiled embolus. 
Diagnosis. Females are distinguished by having a single, narrow 
median, posterior epigynal lobe (Figs. 42, 43) rather than a pair of 
posterior epigynal lobes, and by each epigynal duct making five 
rather than the usual single loop (Fig. 44). Males are distinguished 
by an embolus which loops twice rather than once around the
