Diagnosis

Females of Lasioglossum zephyrus   can be recognized by the metapostnotum smooth with rugae reaching about halfway to the posterior margin, acarinarial fan dense and often complete, mesosoma with fine and often sparse punctures (i=1–2 pd), metasoma mostly dark and often with metallic green terga, head often large with gena much broader than eye and ocelloccipital distance equal to or greater than interocellar distance, and pronotal ridge absent. They are most similar to L. kunzei   and L. semibrunneum   . Both of these species have the pronotal ridge carinate, acarinarial fan sparse, mesosoma very sparsely punctate (i=1–6 pd), and gena sometimes with a ventral tubercle.

Males of L. zephyrus   can be recognized by the propodeum dorsolateral slope rugose and lateral face smooth and tessellate, mesosoma with fine and often sparse punctures (i=1–2 pd), paraocular area with dense tomentum, T2–5 with at least some tomentum, flagellomeres relatively long (F2 about 2 times as long as F1 and 1.75 times as long as broad), and pronotal ridge absent. They are most similar to L. testaceum   , L. pictum   , L. arenisaltans   sp. nov., L. kunzei   , and L. semibrunneum   . Males of L. testaceum   can be separated by the characters given in the key. Males of L. pictum   and L. arenisaltans   sp. nov. have the propodeum lateral face rugulose and mesosoma with larger and denser punctures (i =1–2 pd). Males of L. kunzei   and L. semibrunneum   have the pronotal ridge carinate, flagellomeres relatively short (F2 about 1.3 times as long as F1 and 1.25 times as long as broad), and propodeum dorsolateral slope smooth and shiny.

Etymology

It is evident from his capitalization that Smith (1853) named this species after Zephyrus, the Greek god of the west wind. As a noun, it is not declinable to zephyrum   , in contrast with common past usage ( Batra 1964, 1965, 1966; Michener et al. 1971a, 1971b; Michener 1974, 1990; Wolf & Ascher 2009; Scott et al. 2011; Gibbs 2010, 2011; Dibble et al. 2017; Gibbs et al. 2017). It has almost universally been spelled zephyrum   in combination with Lasioglossum   with the exception of Michener (1951).

DNA barcodes

Sixteen sequences available (BOLD process IDs: ASBEE076-08, BOWGF1435-10, DLII675-07, DLII688-07, DLII702-07, DLII1512-08, DLII1519-08, DIAL070-06, DIAL071-06, DIAL606-06, DIAL725-06, DIAL952-06, DIAL1253-08, DIAL1254-08, DIAL1255-08, LASNA058-08; BIN: BOLD:AAD0272). No unique fixed substitutions distinguish L. zephyrus   from all other western redtailed L. ( Dialictus   ).

Remarks

Unlike other red-tailed L. ( Dialictus   ), it is only the male of L. zephyrus   that often has a red metasoma ( Batra 1966).
