Diagnosis

Females of Lasioglossum vierecki   are readily identified by the head and mesosoma covered in very short, dense, thickly plumose, golden yellow hair and very dense punctures (i <1 pd), face relatively long (length/width ratio ~0.87), metapostnotum dull and finely reticulate with weak rugae, metasomal terga with dense tomentum, and T2 without dark spiracular spots. Unworn specimens are not likely to be confused with any other species, but worn specimens can resemble L. arenisaltans   sp. nov. Females of L. arenisaltans   sp. nov. have the metapostnotum shiny with strong rugae, scutum with slightly sparser punctures (but still very dense), and T2 with dark spiracular spots.

Males of L. vierecki   can be recognized by the scutum very densely punctate (all punctures touching with no distinct interspaces), metasomal terga uniformly densely punctate (i ≤ 1 pd), wings lightly infuscated, head and mesosoma golden-green with yellowish hair, and gonostylus short and broad with long hair. They are most similar to L. cactorum   sp. nov. and L. spivakae   sp. nov. Both of these species have the scutum more sparsely punctate (i=1–3 pd), wings hyaline, and head and mesosoma blue-green with white hair. In addition, males of L. cactorum   sp. nov. have T1–4 rims strongly downcurved.

Etymology

Crawford (1904) dedicated this species to H.L. Viereck.

DNA barcodes

Thirteen sequences available (BOLD process IDs: BWTWO1088-10, DLII314-07, DLII471-07, DIAL033-06, DIAL034-06, DIAL035-06, DIAL121-06, DIAL358-06, DIAL370-06, DIAL479-06, DIAL480-06, DIAL484-06, DIAL915-06; BIN: BOLD:AAB4651). No unique fixed substitutions distinguish L. vierecki   from all other western red-tailed L. ( Dialictus   ).

Remarks

Lasioglossum vierecki   is a primarily eastern species, but it occurs sympatrically with several western species at the western edge of its range. It is believed to be a bivoltine solitary species ( Knerer 1969; Packer 1993) and a sand habitat specialist.
