Diagnosis. Female L. versans can be recognised by the following diagnostic combination: metapostnotal rugae extending less than 2 / 3 distance to posterior margin, posterior margin distinctly extending beyond adjacent dorsal surface of propodeum; T 1 declivitous surface with sparse erect pubescence but no acarinarial fan ( Fig. 9 View FIGURE 9 B); and apical impressed areas of metasomal terga impunctate. They are most similar to L. hemimelas , which has metapostnotal rugae reaching or nearly reaching the posterior margin ( Fig. 133 View FIGURE 133 ).

Male L. versans can be recognised by the following diagnostic combination: metapostnotal rugae reaching 2 / 3 distance to posterior margin, and penis valve with large dorsal crest.

Range. Nova Scotia, Prince Edward Island, west to Alberta, south to North Carolina. USA: CO, CT, IL, MA, MD, ME, MI, MN, NC, NH, NY, PA, SD, TN, VA, VT, WI. CANADA: AB, MB, NB, NS, ON, PE, SK.

DNA Barcode. Available. Multiple sequences.

Comments. Common.

To maintain stable usage of the name, the specimen indicated above is designated as the lectotype. The name-bearing type has lectotype labels from both Mitchell and Covell. No publication by either of these authors could be found that makes a valid lectotype designation.
