Diagnosis

Females of Lasioglossum hudsoniellum can be recognized by the face shiny with dense but distinctly separated and similarly-sized punctures over the frons and paraocular area, mesepisternum with crowded punctures (i =0 pd), scutum usually moderately densely and evenly punctate (i ≤ 1–2 pd), T1 usually with moderately dense punctures (i=1–2 pd) outlining distinct impunctate apicolateral ovals (present but less distinct in most other species), pronotal angle usually about 90 degrees, postgena shiny, and T2 without dark spiracular spots. They are most similar to L. spivakae sp. nov., L. arenisaltans sp. nov., and L. lilianae sp. nov. Females of L. spivakae sp. nov. have the scutum punctures with interspaces 2–3 pd wide immediately mesad of the parapsidal line, metasoma with tomentum mostly restricted to T3–4, pronotal angle obtuse, and metasomal terga usually with sharply delineated brown to black bands. Females of L. arenisaltans sp. nov. have the frons punctures crowded and indistinct, scutum punctures very dense (i <1 pd), postgena lineate, and T2 with dark spiracular spots. Females of L. lilianae sp. nov. have the scutum and T1 more finely and sparsely punctate (i =1–4 pd in part).

Males of L. hudsoniellum can be recognized by S5 apical rim strongly concave, flagellomeres relatively short (F2 about 1.25 times as long as F1 and about as long as broad), face below eye emargination covered in dense tomentum, T1–3 rims usually moderately densely punctate (i=1–2 pd), and T1–5 with abundant tomentum. They are most similar to L. arenisaltans sp. nov. and L. imbriumbrae sp. nov. Both of these species have S5 apical rim straight and metasoma with tomentum sparse or absent. In addition, males of L. arenisaltans sp. nov. have the flagellomeres relatively longer (F2 about 1.75 times as long as F1 and 1.5 times as long as broad), and males of L. imbriumbrae sp. nov. have T1–3 rims impunctate.

Etymology

Cockerell (1919) named this species after the Hudsonian life zone in the Rocky Mountains, where the type specimen was collected, plus the Latin adjectival diminutive suffix - ellus.

DNA barcodes

Twnety-four sequences available (BOLD process IDs: DLII021-06, DLII052-06, DLII785-07, DLII801-07, DLII851-07, DLII852-07, DLII874-07, DLII912-07, DLII913-07, DLII983-07, DLII999- 07, DLII1032-07, DLII1079-07, DLII1083-07, DLII1125-07, DLII1127-07, DLII1266-08, DLII1273- 08, DLII1472-08, DLIII103-18, DIAL1111-07, DIAL1128-07, DIAL1130-07, DIAL1138-07; BINs: BOLD:AAB5530, BOLD:ABZ0512, BOLD:ACE7697). There is a deep divergence between some of these sequences (maximum p-distance 3.21%) compared to the divergence between L. hudsoniellum and its nearest neighbour, L. nymphale (minimum p-distance 1.68%). No unique fixed substitutions distinguish L. hudsoniellum from all other western red-tailed L. ( Dialictus).

Remarks

Lasioglossum hudsoniellum is undoubtedly the most common and widespread of the red-tailed L. ( Dialictus). It occurs in all habitats from prairies to mountains to deserts. There is considerable variation in several characters over its range, which has led to much confusion with identification. Specimens from the easternmost part of its range in the Great Plains often have a black metasoma (even in the female), specimens from the western deserts often have pale wings with white hairs, and specimens from Texas and Mexico often have sparser punctures of the mesosoma and T1. In addition, there is significant variation in the length of the face, but this does not seem to be correlated with any other characters.

Given such extreme morphological, genetic, and geographic variation, L. hudsoniellum seems likely to include some cryptic species. However, clear consistencies between these sources of variation cannot be found to support a species hypothesis.
