Lasioglossum (Dialictus) atwoodi Gibbs, 2010b: 73 View Cited Treatment . Ƥ.

Holotype. Ƥ CANADA, Ontario, Algonquin P.P., Madawaska Lake, 7–19.vi.2007 (E. Proctor); [ PCYU]. Examined.

Diagnosis. Female L. atwoodi can be recognised by the following diagnostic combination: head moderately wide (length/ width ratio = 0.96–0.98); supraclypeal area wide, sparsely punctate (i=1–4d); mesoscutum tessellate-imbricate, punctation moderately coarse, moderately sparse on between parapsidal lines (i=1–2d); tegula reddish brown; mesepisternum strongly rugose; metapostnotal rugae nearly reaching the posterior margin; T1 acarinarial fan with dorsal opening; metasomal terga brown with the apical halves obscurely punctate; and T4 with scattered tomentum not obscuring surface. They are most similar to L. viridatum , which has denser supraclypeal punctures, metapostnotal rugae reaching the posterior margin, and T4 with sparse tomentum partially obscuring surface.

Male unknown.
