Lasioglossum ( Dialictus) succinipenne (Ellis) View in CoL

Halictus succinipennis Ellis, 1913: 205 . Ƥ.

Holotype. Ƥ USA, Colorado, Florissant, 14.vi.1948 on sand (S.A. Rohwer); [ NMNH: 28200]. Examined.

Taxonomy. Michener, 1951: Lasioglossum ( Chloralictus) succinipenne , p. 1118 (catalogue); Hurd, 1979: Dialictus succinipennis , p. 1972 (catalogue); Dialictus succinipennis , p. 1972 (catalogue); Moure & Hurd, 1987: Dialictus succinipennis , p. 132 (catalogue); Gibbs, 2010b: Lasioglossum ( Dialictus) succinipenne Ƥ3, p. 317 (redescription, key).

Diagnosis. Female L. succinipenne can be recognised by the following diagnostic combination: head long (length/ width ratio = 1.05–1.09), clypeus apicolateral margins weakly convergent, supraclypeal area elongate, mesoscutal punctures dense throughout (i<d), metapostnotum rugoso-carinulate, and metasomal terga metallic, with dense, whitish tomentum. They are most similar to L. pilosum and L. leucocomum . Female L. pilosum have subparallel apicolateral margins of clypeus and distinctly yellowish pubescence. Female L. leucocomum have a shorter supraclypeal area.

Male L. succinipenne can be recognised by the following combination: head long (length/width ratio = 1.09–1.21), eyes strongly convergent below (UOD/LOD ratio = 1.38–1.48), clypeus yellow distally, mesoscutal punctures dense, mesepisternum with obscure punctures, metapostnotum rugoso-carinulate, metasomal terga metallic with dense and distinct punctures. They are most similar to L. pilosum , which lacks mesepisternal punctures.

Range. Alberta and Manitoba south to Colorado, west to Illinois and southern Ontario. USA: CO, IL, MN, NE, WI. CANADA: AB, MB, ON.

DNA Barcode. Available. Multiple sequences.

Comments. Common in Midwest. Until recently, L. succinipenne was only known from Colorado. It was later identified from Manitoba ( Patenaude 2007) and subsequently from numerous Midwestern sites (Wolf & Ascher 2009; Gibbs 2010b).
