Lasioglossum (Dialictus) michiganense (Mitchell)

Paralictus michiganensis Mitchell, 1960: 448 . Ƥ.

Holotype. Ƥ USA, Michigan, Wayne Co., 2.vi. 1940, [ NCSU].

Taxonomy. Krombein, 1967: Lasioglossum (Paralictus) michiganense , p. 467; (catalogue); Hurd, 1979: Paralictus michiganensis , p. 1974 (catalogue); Moure & Hurd, 1987: Paralictus michiganensis , p. 143 (catalogue); Gibbs, 2010 b: Lasioglossum (Dialictus) michiganense Ƥ 3, p. 191 (redescription, key).

Diagnosis. Female L. michiganense can be recognised by the following diagnostic combination: head wide (length/ width ratio = 0.84–0.85); labrum with apical process flat, dorsal keel absent ( Fig. 6 View FIGURE 6 B); mandible with preapical tooth present ( Fig. 30 View FIGURE 30 B); gena wider than eye; and mesepisternum with vertical carinula.

Male L. michiganense can be recognised by the following diagnostic combination: pronotum strongly carinulate; mesoscutum with weak microsculpture, punctures fine, sparse between parapsidal lines; metasomal sterna with very sparse hairs; and S 7 median lobe clavate. They are most similar to L. platyparium , which has S 7 median lobe acuminate.

Range. Southern Ontario south to North Carolina, west to Wisconsin. USA: DC, IL, MI, NC, NY. CANADA: ON.

DNA Barcode. Available. Multiple sequences.

Comments. Rare.

Lasioglossum michiganense is presumed to be a social parasite or cleptoparasite of nest-building Lasioglossum ( Dialictus ).
