Lasioglossum (Dialictus) illinoense (Robertson)  

Halictus illinoensis Robertson, 1892: 271   . Ƥ.

Lectotype. Ƥ USA, Illinois, Macoupin Co., Carlinville, 12.viii. 1891, (C. Robertson); [ INHS: 11933] by W. E. LaBerge (in Webb 1980). Examined.

Halictus illinoisensis Smith, 1910: 688   . (Emend.)

Taxonomy. Robertson, 1902 b: Chloralictus Illinoensis   , p. 249 (key); Michener, 1951: Lasioglossum (Chloralictus) illinoense   , p. 1114 (catalogue); Mitchell, 1960: Dialictus illinoensis   Ƥ 3, p. 399 (redescription, key); Krombein, 1967: Lasioglossum (Dialictus) illinoense   , p. 464 (catalogue); Hurd, 1979: Dialictus illinoensis   , p. 1966 (catalogue); Moure & Hurd, 1987: Dialictus illinoensis   , p. 105 (catalogue); Gibbs, 2010 b: Lasioglossum (Dialictus) illinoense   Ƥ 3, p. 149 (redescription, key).

Diagnosis. Female L. illinoense   can be distinguished from all other North American Dialictus   by protrochanter conically produced ( Fig. 8 View FIGURE 8 A). They are further recognisable by the combination of head wide (length/width ratio = 0.90– 0.92); clypeus with wide distal margin; propodeum with very strong carina delimiting lower margin of dorsolateral slope; and mesoscutal punctures fine, sparse between parapsidal lines, denser laterad of parapsidal line.

Male L. illinoense   can be recognised by the following diagnostic combination: clypeus with distal margin yellow; head wide (length/width ratio = 0.94–0.95); mesoscutum with posterior half polished due to lack of microsculpture, punctures fine, sparse between parapsidal lines (i= 1–3 d); mesepisternum rugulose; metasomal terga with apical halves impunctate except along premarginal line; and metasomal sterna with relatively sparse plumose hairs.

Range. Nova Scotia, south to Georgia, Mississippi, west to Kansas. USA: GA, IL, IN, KS, KY, MD, MI, NC, NJ, NY, PA, SC, TN, TX, VA, WI, WV.

DNA Barcode. Available. Multiple sequences.
