Diagnosis. Both sexes of L . foveolatum can be distinguished by parapsidal line deep and wide, equal to about three puncture diameters ( Fig. 15 B). Female L . foveolatum may be further distinguished by supraclypeal area strongly convex and lower paraocular area tessellate with sparse punctures (i=1–2d). They are most similar to L. ceanothi , which have parapsidal line narrow and lower paraocular punctures denser. Male L . foveolatum have mesepisternal punctures distinct, and sometimes propodeal lateral surfaces punctate, too. Range. Southern Ontario and Connecticut, south to Georgia , west to Missouri.
