Lasioglossum (Dialictus) subversans (Mitchell)

Dialictus subversans Mitchell, 1960: 419 . Ƥ.

Holotype. Ƥ USA, Michigan, Otsego Co., 26.iv. 1944 (R.R. Dreisbach); [ NCSU]. Examined. Dialictus perpunctatulus Knerer and Atwood, 1966 a: 884 . Ƥ 3.

Holotype. Ƥ CANADA, Ontario, Arctic Watershed, Timiskaming District, 21.vi. 1961 on Fragaria, (G. Knerer) ; [ ROM:

83912]. Examined.

Taxonomy. Krombein, 1967: Lasioglossum (Dialictus) subversans , p. 466 (catalogue); Dialictus perpunctatulus , p. 1970, D. subversans , p. 1972 (catalogue); Moure & Hurd, 1987: Dialictus perpunctatulus , p. 121, D. subversans , p. 132 (catalogue); Gibbs, 2010 b: Lasioglossum (Dialictus) subversans Ƥ 3, p. 309 (redescription, key, synonymy).

Diagnosis. Female L. subversans can be recognised by the following diagnostic combination: head wide (length/ width ratio = 0.94–0.97); supraclypeal area strongly brassy; mesoscutum imbricate, punctures moderately dense between parapsidal lines (i= 1–1.5 d); mesepisternal punctures distinct but irregular; metapostnotum with weak longitudinal rugae, not reaching rounded posterior margin; and metasomal terga brown, with sparse tomentum, apical punctation very obscure. They are most similar to L. foveolatum , which has a strongly convex supraclypeal area and wide parapsidal lines.

Male L. subversans can be distinguished from all other eastern USA L. ( Dialictus ) by the very long and dense scopalike hairs on S 2 –S 3 and apicolateral portions of S 4 –S 5 ( Fig. 35 View FIGURE 35 A).

Range. Nova Scotia west to British Columbia. USA: ME, MI. CANADA: AB, BC, NB, NS, ON, PE, PQ, SK.

DNA Barcode. Available. Multiple sequences.

Comments. Rare. Lasioglossum subversans seems to have a boreal distribution.
