Lasioglossum (Dialictus) tegulare (Robertson)  

Halictus tegularis Robertson, 1890: 318   . Ƥ 3.

Holotype. Ƥ USA, Connecticut, N. Haven, 6 June 1878, (W.H. Patton); [ ANSP: 4254] designated herein. Examined.

Taxonomy. Robertson, 1902 b: Chloralictus tegularis   , p. 248 (key); Viereck, 1916: Halictus (Chloralictus) tegularis   , p. 706 (key); Michener, 1951: Lasioglossum (Chloralictus) tegulare   , p. 1118 (catalogue) Mitchell, 1960: Dialictus tegularis   Ƥ 3, p. 423 (redescription, synonymy); Krombein, 1967: Lasioglossum (Dialictus) tegulare   , p. 466 (catalogue); Dialictus tegularis   , p. 1972 (catalogue); Moure & Hurd, 1987: Dialictus tegularis   , p. 134 (catalogue); Gibbs, 2009 a: Lasioglossum (Dialictus) tegulare   Ƥ 3, p. 13 (redescription, tax. status); Gibbs, 2010 b: Lasioglossum (Dialictus) tegulare   Ƥ 3, p. 323 (redescription, key).

Diagnosis. Female L. tegulare   can be recognised by the following diagnostic combination: tegula enlarged, strongly punctate with distinct posterior angle ( Fig. 7 View FIGURE 7 A); head relatively wide (length/width ratio = 0.94–0.97); head and mesosoma greenish; mesepisternum with strong microsculpture between punctures; and inner metatibial spur with 3–4 branches (excluding apex of rachis).

Male L. tegulare   also have an enlarged tegula and can be distinguished from similar species by dense punctures on T 2 immediately basal of premarginal line ( Fig. 38 View FIGURE 38. T 2 A) and sparse facial tomentum, except on lower paraocular area. They are most similar to L. ellisiae   and L. puteulanum   . Male L. ellisiae   have sparse punctures on T 2 immediately basal of premarginal line ( Fig. 38 View FIGURE 38. T 2 B). Male L. puteulanum   have more tomentum distributed outside of lower paraocular area.
