Diagnosis. Female L. bruneri   can be recognised by the diagnostic character of hypostomal carinae widely divergent ( Fig. 11 View FIGURE 11 B) and strongly produced distally. They may be further distinguished by the following: size large, head and mesosoma coarsely sculptured, and protrochanter excavated anteriorly. They are very similar to L. reticulatum   , which has less widely divergent hypostomal carinae, which are not produced distally, and normal trochanters without anterior excavation.

Male L. bruneri   can be recognised by the following diagnostic combination: mesoscutum rugose anteriorly, mesepisternum coarsely rugose, and tibiae and femora brown. They are most similar to L. reticulatum   , which has the tibiae and femoral apices and bases reddish brown. Male L. cressonii   are also similar but have distinct mesoscutal punctures anteriorly and less clypeal pubescence, not obscuring the surface.

Range. Ontario south to Florida, west to Nebraska. USA: GA, IL, IN, KS, MA, MD, MI, NC, NE, NM, NY, SC, TN, TX, VA, WI, WV. CANADA: ON.

DNA Barcode. Available. Multiple sequences.

Comments. Common.

Some females of L. bruneri   , particularly in the Midwest, do not have strongly produced hypostomal carinae. These have sometimes been mistaken for L. reticulatum   .
