Lasioglossum (Dialictus) foveolatum (Robertson)  

Chloralictus foveolatus Robertson, 1902 b: 250   . 3.

Lectotype. 3 USA, Illinois, Macoupin Co., Carlinville, 31.x. 1901 (C. Robertson); [ INHS: 23049] by W. E. LaBerge (in Webb 1980). Examined.

Dialictus supraclypeatus Mitchell, 1960: 420   . Ƥ.

Holotype. Ƥ USA, Virginia, Dunn Loring, 26.vi. 1948, (K.V. Krombein); [ NMNH: 66071]. Examined.

Taxonomy. Michener, 1951: Lasioglossum (Chloralictus) foveolatum   , p. 1113 (catalogue); Mitchell, 1960: Dialictus foveolatus   3, p. 394 (redescription); Krombein, 1967: Lasioglossum (Dialictus) foveolatum   , p. 463, L. (D.) supraclypeatum   , p. 466 (catalogue); Hurd, 1979: Dialictus foveolatus   , p. 1966, D. supraclypeatus   , p. 1972 (catalogue); Moure & Hurd, 1987: Dialictus foveolatus   , p. 101, D. supraclypeatus   , p. 132 (catalogue); Gibbs, 2010 b: Lasioglossum (Dialictus) foveolatum   Ƥ 3, p. 132 (redescription, key, synonymy).

Diagnosis. Both sexes of L. foveolatum   can be distinguished by parapsidal line deep and wide, equal to about three puncture diameters ( Fig. 15 View FIGURE 15 B). Female L. foveolatum   may be further distinguished by supraclypeal area strongly convex and lower paraocular area tessellate with sparse punctures (i= 1–2 d). 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. USA: CT, GA, IL, IN, MD, MO, NJ, VA, WI. CANADA: ON.

DNA Barcode. Available. Multiple sequences.
