Diagnosis.

Ummidia beatula are relatively small spiders which can be differentiated from U. rongodwini by males lacking a pale dorsal heart patch and from U. audouini and U. rosillos by lacking a brush on the retrolateral face of tarsus IV. In males, the comb on tarsus IV is less distinct than that of U. funerea and U. colemanae . Males can be differentiated from U. macarthuri and U. rongodwini by the presence of prolateral spines on tibia I. Males disperse from April to June.
