Lasioglossum (Dialictus) paradmirandum (Knerer & Atwood)  

Dialictus paradmirandus Knerer and Atwood, 1966 a: 886   . Ƥ 3.

Holotype. Ƥ CANADA, Ontario, Iona, Elgin Co., 1.ix. 1963 on Solidago, (G. Knerer)   , [ ROM: 83856]. Examined.

Taxonomy. Hurd, 1979: Dialictus paradmirandus   , p. 1969 (catalogue); Moure & Hurd, 1987: Dialictus paradmirandus   , p. 119 (catalogue); Gibbs, 2010 b: Lasioglossum (Dialictus) paradmirandum   Ƥ 3, p. 237 (redescription, key).

Diagnosis. Female L. paradmirandum   can be recognised by the following diagnostic combination: mesoscutum tessellate, punctures moderately dense between parapsidal lines (i= 1–2 d); mesepisternum tessellate-imbricate, shallow punctures visible; T 1 acarinarial fan with dorsal opening; T 1 declivitous surface with distinct coriarious microsculpture; T 3 –T 4 with moderately dense tomentum partially obscuring surface and distinct apical fringes. They are most similar to L. fattigi   and L. admirandum   . Female L. fattigi   have a more robust head, moderately sparse punctures on lower paraocular area (i= 1–1.5 d), weakly imbricate mesoscutum, and T 3 –T 4 have sparse tomentum not obscuring surface and sparse apical fringe hairs. Female L. admirandum   have metasomal terga polished without evident microsculpture on declivitous surface of T 1.

Male L. paradmirandum   are similar to females but may be further distinguished by head moderately elongate (length/width ratio = 1.03–1.04); flagellomeres long (length/width ratio = 1.69–1.83), pale brownish yellow ventrally; mesepisternum weakly reticulate dorsally, tessellate ventrally; metapostnotum rounded onto posterior propodeal surface, and apical impressed areas of metasomal terga impunctate. They are most similar to L. mitchelli   and L. fattigi   . Male L. mitchelli   have metapostnotum sharply angled onto posterior propodeal surface, mesoscutum more densely punctate, and mesepisternum rugulose. Male L. fattigi   have elongate heads (length/width ratio = 1.07) and mesepisternum imbricatetessellate dorsally.

Range. Ontario south to North Carolina, west to Wisconsin, Iowa. USA: IA, IL, IN, MD, MI, MO, NC, NY, PA, WI, WV. CANADA: ON.
