Halictus albitarsellus Warncke, 1973: 294   . (new name for H. albitarsis Cresson   )

Taxonomy. Cockerell, 1907: Halictus albitarsis   , p. 38 (tax. notes); Cockerell, 1937a: Halictus (Chloralictus) disparilis   , p. 113 (diagnosis); Michener, 1951: Lasioglossum (Chloralictus) albitarse   , p. 1111, L. (C.) disparile   , p. 1113 (catalogue); Krombein, 1967: Lasioglossum (Dialictus) brassicae   , p. 462 (catalogue); Hurd, 1979: Dialictus albitarsis   , p. 1963, D. brassicae   , p. 1964, D. disparilis   , p. 1966 (catalogue); Moure & Hurd, 1987: Dialictus albitarsis   , p. 89, D. brassicae   , p. 92, D. disparilis   , p. 99 (catalogue); Gibbs, 2010: Lasioglossum (Dialictus) disparile   (tax. notes, synonymy).

Diagnosis. See Gibbs (2010). The female of L. disparile   has a diagnostic hair pattern on the declivitous surface of T1. The strong acarinarial fan is separated from a dorsal transverse hair band by a transverse glabrous area. The male of L. disparile   has the diagnostic combination of a strong genal tubercle and distinct mesepisternal punctures.

Comments. Common in Texas. Questionable Canadian records for this species exist from Ontario (as L. albitarse   ) ( Michener 1951) and southern Alberta (as H. disparilis   ) ( Cockerell 1937a). The Canadian records cannot be confirmed and no credible records north of Kansas or North Carolina have been found. The species has accordingly been excluded from the keys and descriptions. The female runs to couplet 69 but does match any species in the key. The male runs to L. zephyrum   but is easily distinguished by the genal tubercle. See Gibbs (2010) for additional information on the taxonomy and identification of this species.

Warncke’s (1973) replacement name for H. albitarsis   has never been widely applied. The catalogues published subsequent to Warncke’s study ( Hurd 1979; Moure & Hurd 1987) classified Dialictus   and Evylaeus   as separate genera which removed the need for the replacement name. If transferred to Lasioglossum   , Halictus albitarsis Cresson, 1872   becomes a junior secondary homonym of Hylaeus albitarsis Schenck, 1853   which is a junior synonym of L. (E.) fulvicorne ( Kirby, 1802)   .
