Lasioglossum (Dialictus) cattellae (Ellis)  

Halictus cattellae Ellis, 1913: 209   . Ƥ 3.

Holotype. Ƥ USA, New York, Garrison, [ UCMC]. Examined. Dialictus alternatus Mitchell, 1960: 433   . 3.

Holotype. 3 USA, Massachusetts, Forest Hills, 29–30.viii. 1922 (W.M. Wheeler); [ MCZ: 30469]. Examined.

Taxonomy. Michener, 1951: Lasioglossum (Chloralictus) cattellae   , p. 1112 (catalogue); Mitchell, 1960: Dialictus cattellae   Ƥ, p. 386 (redescription, key); Krombein, 1967: Lasioglossum (Dialictus) alternatum   , p. 462, L. (D.) cattellae   , p. 462 (catalogue); Hurd, 1979: Dialictus alternatus   , p. 1964, D. cattellae   , p. 1965 (catalogue); Moure & Hurd, 1987: Dialictus alternatus   , p. 89, D. cattellae   , p. 94 (catalogue); Gibbs, 2010 b: Lasioglossum (Dialictus) cattellae   Ƥ 3, p. 89 (redescription, key, synonymy).

Diagnosis. Female L. cattellae   can be recognised by the following diagnostic combination: head and mesosoma golden green; metasoma vaguely metallic; mesoscutum with yellowish woolly hairs, punctures moderately coarse, sparse medially (i= 1–2 d); mesepisternal punctures distinct and well spaced (i= 1–2 d); T 1 acarinarial fan without dorsal opening; metasomal terga with sparse punctures basally and nearly impunctate apically, except along premarginal line. They are most similar to L. tenax   , which is bluish green with finer mesoscutal punctures and dull white woolly hairs on the mesoscutum.

Male L. cattellae   can be recognised by the following diagnostic combination: mesepisternal punctures deep and distinct, and metasomal terga with punctures dense across disc except apical impressed areas impunctate. They are most similar to L. perpunctatum   , and L. tenax   . Male L. perpunctatum   have apical impressed areas of metasomal terga punctate. Male L. tenax   have sparse punctures anterior to premarginal line and are usually impunctate on the mesepisternum.

Range. Massachusetts, Michigan south to Georgia, west to Kansas, possibly Ontario and Quebec. USA: GA, IL, IN, KS, MA, MD, MI, MO, NC, NY, OH, TN, WV.

DNA Barcode. Available. Multiple sequences. DNA barcodes do not clearly differentiate L. cattellae   and L. tenax   .

Comments. Uncommon.
