Lasioglossum (Dialictus) novascotiae (Mitchell)

Dialictus novascotiae Mitchell, 1960: 407 . Ƥ.

Holotype. Ƥ Canada, Nova Scotia, Baddeck, 27.viii. 1926, [ NCSU]. Examined.

Taxonomy. Knerer & Atwood, 1964: Dialictus novascotiae 3, p. 5 (description); Krombein, 1967: Lasioglossum (Dialictus) novascotiae , p. 464 (catalogue); Hurd, 1979: Dialictus novascotiae , p. 1968 (catalogue); Moure & Hurd, 1987: Dialictus novascotiae , p. 115 (catalogue); Gibbs, 2010 b: Lasioglossum (Dialictus) novascotiae Ƥ 3, p. 207 (redescription, key).

Diagnosis. Female L. novascotiae can be recognised by the following diagnostic combination: head wide (length/ width ratio = 0.95–0.96), clypeus strongly protruding below suborbital tangent, mesoscutal punctures sparse throughout, mesepisternum rugulose, propodeum with dorsolateral slope rugulose ( Fig. 27 View FIGURE 27 B), and metasomal terga blackish brown. They are most similar to L. lineatulum , which has head wider (length/width ratio = 0.92–0.93), propodeum with dorsolateral slope smooth ( Fig. 27 View FIGURE 27 A), and metasomal terga with metallic reflections.

Male L. novascotiae can be recognised by the following diagnostic combination: mesoscutal punctures sparse throughout, mesepisternum rugulose, and metasomal sterna with subappressed plumose hairs limited to apicolateral portions of S 3 and lateral portions of S 4 –S 5. They are similar to L. lineatulum , which has dense plumose hairs on S 2 –S 4 and S 5 laterally. Lasioglossum achilleae is similar but has a shorter head and sparse punctation on metasomal terga.

Range. Nova Scotia west to Alaska, south to Michigan. USA: AK, ME, MI. CANADA: AB, BC, NB, NS, NT, ON, PE, SK.

DNA Barcode. Available. Multiple sequences.

Comments. Common in some localities.
