Lasioglossum (Dialictus) ellisiae (Sandhouse)

Halictus (Chloralictus) ellisiae Sandhouse, 1924: 11 . Ƥ.

Holotype. USA, Massachusetts, Forest Hills, 5.viii. 1901, (W.M. Wheeler); [ NMNH: 26400]. Examined.

Taxonomy. Michener, 1951: Lasioglossum (Chloralictus) ellisiae , p. 1113 (catalogue); Mitchell, 1960: Dialictus tegularis Ƥ 3 (in part), p. 423 (redescription, key, synonymy); Gibbs, 2009 a: Lasioglossum (Dialictus) ellisiae Ƥ 3, p. 18 (redescription); Gibbs, 2010 b: Lasioglossum (Dialictus) ellisiae Ƥ 3, p. 120 (redescription, key).

Diagnosis. Female L. ellisiae can be recognised by the following diagnostic combination: tegula enlarged, strongly punctate with distinct posterior angle ( Fig. 7 View FIGURE 7 A), and mesepisternal punctures separated by smooth interspaces with very little microsculpture. They are most similar to L. tegulare , which has strong microsculpture between the mesepisternal punctures.

Male L. ellisiae also have an enlarged tegula ( Fig. 7 View FIGURE 7 A) and can be distinguished from similar species by sparse punctation on T 2 immediately basal of premarginal line ( Fig. 38 View FIGURE 38. T 2 B). They are most similar to L. tegulare , which has uniformly dense punctures on T 2 basal of premarginal line.

Range. Ontario and Massachusetts, west to Minnesota, and south along the Appalachian Mountains to North Carolina. USA: IL, IN, MA, ME, MI, MN, NC, NY, PA, WI. CANADA: ON.

DNA Barcode. Available. Multiple sequences.

Comments. Common. Until recently, L. ellisiae was considered a synonym of L. tegulare ( Gibbs 2009 a, see also Gibbs 2010 b). For a complete treatment of L. ellisiae and related species in eastern North America see Gibbs (2009 a).
