Great spider. I'm not convinced it's Theridiidae because the legs are fairly short. Can you give a size estimate?

a check; Hypsosinga variabilis of after review;

THE ORB-WEAVER GENERA SING.4 AND ,HYPSOSING.4
IN AMERICA

 
H. variabilis = H. pygmaea
H. variabilis is no longer a name in this genus. It has since been changed to H. pygmaea.

Notes from Levi, 1972

The only character of possible diagnostic value mentioned(for this species) is that the anterior lateral eyes are larger than the posterior laterals.

The coloration of the abdomen is from black to
yellowish white, the light specimens may have four dorsal black
spots on the abdomen, rarely two bands
(Fig. 54). The females
are 2.9-3.9 mm total length, carapace 1.0-1.5 mm wide. Males are
2.2-2.6 mm total length, carapace 1.0-1.9 mm wide. The largest
specimens come from the northern part of the range, the smallest
from the southern.
Diagnosis. Hypsosinga variabilis is closest to H. sanguinea of
Eurasia, the long embolus (Figs. 55-57), the wide median septum
of the epigynum (Figs. 47, 49) of I?. variabilis separates it from
other American species.
Natural History. The only observations are from sweeping it
from a wet meadow in Minnesota, and roadside grass in Manitoba;
vegetation bordering canal in Florida. The males are mature in
May and June, females have been collected adult in May to July,
in August to February in Florida.
Distribution. From Alaska and Cartwright, Labrador to Havana,
Cuba.
