Diagnosis

Both sexes of Lasioglossum tuolumnense  can be recognized by the characters for the Lasioglossum petrellum  species complex (below), in addition to the characters given in the keys. Females are most similar to L. griswoldi  , and probably males as well (the male of L. griswoldi  is not described). Females of L. griswoldi  have the malar space and supraclypeal area longer, and scutum slightly shinier and less densely punctate. In addition, the geographic ranges of these two species are not known to overlap: L. tuolumnense  is only known from the mountains of California north to British Columbia, while L. griswoldi  is only known from Utah and Colorado.

DNA barcodes

Seven sequences available (BOLD process IDs: DLII296-07, DLII302-07, DLII305-07, DLII922-07, DLII942-07, DLII944-07, DLII998-07; BIN: BOLD:AAD3535). Lasioglossum tuolumnense  differs from L. droegei  , L. griswoldi  , and L. petrellum  by 1 fixed substitution: 153(T) (Supplementary file 4). No unique fixed substitutions distinguish L. tuolumnense  from all other western red-tailed L. ( Dialictus  ).

Remarks

At least one specimen from the Cascade Mountains in Oregon has a completely black metasoma. This specimen was not available for physical study, but photographs taken by Joe Engler (FWSE) were examined and match L. tuolumnense  except in colouration.
