Lasioglossum (Dialictus) tegulare (Robertson) View in CoL

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, 1902b: 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 Ƥ3, 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, 2009a: Lasioglossum (Dialictus) tegulare Ƥ3, p. 13 (redescription, tax. status); Gibbs, 2010b: Lasioglossum (Dialictus) tegulare Ƥ3, 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 T2 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 T2 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.
