Bion O.P. -Cambridge, 1898: 244, pi. 30. Type species by monotypy B. brevis O.P.- 
Cambridge, 1898. First synonymized with Witica by Simon, 1903. 
Synonymy. Simon (1903: 1003) synonymized his Physiola pub- 
lished in 1895 with Witica published the same year, as an objective 
synonym. I do not know the month of the publications; Simon 
presumably did and Witica was published earlier. Thus since Salas- 
sina was published at the same time as Physiola it must also have 
been published after Witica. 
F.P. -Cambridge (1904: 500) placed Epeira crassicauda described 
from a female into the genus Edricus. Edricus O.P. -Cambridge, 
1890, has as type species Edricus spinigerus, 1890. Edricus spinige- 
rus was described from a large male similar and perhaps congeneric 
with Wagneriana tauricornis F.P. -Cambridge, 1904. F.P.- 
Cambridge thought that Edricus spinigerus might be the unknown 
male of Epeira crassicauda. This proved to be an error. 
Diagnosis. Unlike the females of most Araneidae, the abdomen 
has a tail usually constricted at its base (Figs. 1, 6) and the epigynum 
is flat, lightly sclerotized, with a pair of depressions, (Figs. 4, 7). The 
male is separated from other Araneidae by the minute size, 1.5- 1.9 
mm (Fig. 5), sclerotized abdomen (Figs. 12, 15) and lacking a 
median apophysis and conductor of the palpus and having a large 
embolus tip which is transferred and plugs the female’s ducts (Figs. 
9,14). 
Description. Female. Carapace, sternum dark brown. Legs light 
with contrasting dark rings. Dorsum of abdomen black with varia- 
ble white patches, venter black with a pair of small, white spots. 
Eyes subequal in size. Chelicerae with three teeth on anterior, three 
on posterior margin. First legs longer than fourth, second and 
fourth subequal, third shortest. Abdomen with a pair of anterior 
blunt spines and a tail of variable shape (Figs. 1, 6). The tail is 
constricted at its base and distally has three lobes. 
Male. Carapace shiny brown, sternum, legs dark brown. Dor- 
sum of abdomen shiny brown, venter black. Eyes subequal in size. 
Median eyes their diameter apart. Cheliceral teeth as in female, leg 
proportions as in female. Endites without tooth, palpal femora 
without tooth, first coxae without hook. Abdomen with round 
convex dorsal shield, sometimes wider than long or longer than 
wide.
