Diagnosis

Females of Lasioglossum clematisellum can be recognized by the characters for the L. clematisellum species complex (below), in addition to the metasomal terga lacking tomentum, the face and mesepisternum often duller than in other species in this group, scutum with most hairs relatively thin and weakly plumose and punctures of anteromedian area indistinct, and head and mesosoma blue-green with bright white hair. They are most similar to L. clastipedion sp. nov. and can only be separated with great difficulty, especially if specimens are worn. Females of L. clastipedion sp. nov. have the metasomal terga with at least some basolateral tomentum; this is the most reliable character. In addition, females of L. clastipedion sp. nov. often have the scutum with most hairs densely plumose and punctures of the anteromedian area distinct, and head and mesosoma more golden-green with slightly yellowish hair dorsally.

Males of L. clematisellum can be recognized by the characters for the Lasioglossum clematisellum species complex (below), in addition to the metasoma lacking tomentum, scutum with many hairs thin and weakly plumose, and frons densely punctate (i <1 pd). They are most similar to L. julipile sp. nov., L. perditum sp. nov., and L. clastipedion sp. nov. All of these species have the scutum with most hairs thick and densely plumose and metasomal terga with at least some basolateral tomentum. In addition, L. julipile sp. nov. and L. perditum sp. nov. have the frons more sparsely punctate (i=1–3 pd).

Etymology

Cockerell (1904) named this species after the plant genus Clematis, plus the Latin adjectival diminutive suffix - ellus.

DNA barcodes

Eight sequences available (BOLD process IDs: DIAL1098-07, DIAL1108-07, DLII755-07, DLII783- 07, DLII1085-07, BOWGF2050-10, BWTWO1316-10, BWTWO1318-10; BIN: BOLD:AAE5948). There is some shallow within-species divergence (maximum p-distance 1.33%), but this is much less than the difference between species in the L. clematisellum complex (minimum p-distance 2.78%). Lasioglossum clematisellum differs from L. clastipedion sp. nov. and L. julipile sp. nov. by 11 fixed substitutions: 18(C), 80(T), 123(C), 141(C), 286(C), 312(T), 354(T), 390(C), 426(C), 474(C), and 579(C) (Supplementary file 4). No unique fixed substitutions distinguish L. clematisellum from all other western red-tailed L. (Dialictus).

Remarks

Common. The male is described here for the first time. Lasioglossum clematisellum has an extremely wide distribution, but unlike the similarly-distributed L. hudsoniellum, L. clematisellum is not found at very high elevations and is more common in deserts.
