Chickering — Genus Scaphiella 
155 
posterior declivity; otherwise essentially typical of females of the 
genus. Eyes: ALE somewhat further separated than in male but 
outlines are obscure and with some irregularities; otherwise essentially 
as in male. Chelicerae, maxillae and lip apparently typical of females 
of the genus. Sternum : general features as usual ; marginal lobes 
moderately well developed ; posterior end squarely truncated and 
just opposite bases of fourth coxae which are separated by nearly 
twice their width. Legs as usual in the genus. Palp : with the 
tarsus somewhat enlarged as usual. Abdomen : with ventral scutum 
as usual in females of the genus; sclerite surrounds the spinnerets 
for about two-thirds of the complete distance; spinnerets as usual; 
epigynal area (Fig. 52) is somewhat distinctive. Color in alcohol: 
typical of the genus in general ; areas of abdomen not covered by 
scutum are a clear white ; other parts somewhat darker than in male. 
Records. The described female paratype, one other female para- 
type and the cephalothorax of a male are all assigned to this species. 
Two other females are tentatively assigned to this species but with 
considerable uncertainty. These were all collected by Dr. N. A. 
Weber but with no date of collection indicated.

Figures 53-54 
Scaphiella williamsi Gertsch, 1941: 11, figs. 18-19. The male holotype from 
Barro Colorado Island, Panama Canal Zone is in the American Museum 
of National History, New York City. Chickering, 1951: 239. 
Dr. Gertsch had only the holotype in 1941. In 1951 I had a fe- 
male which seemed to be the female of this species and at the present 
time there is no reason to believe that an error was made at that 
time. Since 1951 I have acquired three males and six females from 
Barro Colorado Island, Summit Gardens and Gatun all in the 
Panama Canal Zone. Two males from Barro Colorado Island have 
been on loan from the American Museum of Natural History. The 
female palpal tarsus is shown in Figure 53- The epigynal area in 
females seems to follow a fairly consistent pattern with some minor 
vaiiations. Figure 54 shows what appears to be a fairly typical 
epigynal area.
