Structure. For comparison of certain diagnostic measurements of 
S. agalenoides to other species see Table 1. 
Posterior cheliceral margin with three teeth on each side. Of four 
female and one juvenile specimens examined all have 3-3 posterior 
cheliceral teeth. 
Tibial spination in each of the four females is exactly the same as 
that shown in the table for S. calif ornicus. 
Clypeus height is greater than the diameter of the AME in three 
specimens, in one specimen it is subequal to the diameter of the AME. 
Labium longer than wide. 
Color. Pattern illustrated in Figure 9. Carapace light orange- 
brown, darkest in the eye region. A thin median stripe, clothed with 
white hair, begins slightly in front of the third eye row and continues 
to the thoracic groove. Broad marginal longitudinal stripes, not as 
distinct as in S. calif ornicus ; white hairs along these stripes heaviest 
laterally just behind the clypeus, more diffuse posterior to this region. 
The lateral edges of the carapace clothed with fine white hair. Cheli- 
cerae dark reddish brown, almost black; boss on each side prominent, 
with dense white hair surrounding it except at the point of articula- 
tion. 
Sternum light brownish yellow. Endites and labium darker reddish 
brown, yellowish at distal ends. Legs light brownish, yellow with 
metatarsi and trasi darker reddish brown. 
Dorsum of the abdomen with a wide brown median stripe beginning 
at the base and continuing to the spinneretes. The anterior end of 
this stripe bordered by three white dashlines on each side, and inter- 
rupted posteriorly by a series of white chevron markings. These 
markings clothed with white pubescence. A series of dark brown dots 
alternate crossing the dorsum with the white chevrons and continue 
laterally for some distance. Lateral area of abdomen light brownish 
yellow, venter lighter, almost cream colored. 
Diagnosis. Sosippus agalenoides is most similar to S. calif ornicus 
in coloration. It is separated from this species by the shape of the 
epigynum (compare Figs. 29, 30 to Figs. 27, 28). Sosippus agalenoides 
is similar to S. mexicanus in the form of the epigynum. It differs from 
S. mexicanus in size and other characters discussed under that species. 
Natural History. Banks (1909) does not supply any information 
concerning the natural history of this species. Presumably it builds 
the same type of sheet web and tubular retreat as found in S. cali- 
f ornicus. 
Distribution. Morelos, Oaxaca, Costa Rica.
