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).

Description

See Gibbs (2010) for a complete redescription, figures, additional floral records, and reference to biological literature.

Range

Throughout most of the United States and southern Canada, southwest to northern California and Texas ( Fig. 89View Fig).

Floral records

APIACEAE Lindl.  Zizia W.D.J. Koch  : Z. aurea Koch  ASTERACEAE Giseke  : Ageratum  : A. altissima  (L.) R.M. King & H. Rob. • Helianthus  BRASSICACEAE Burnett  : Lepidium  L. • CAPRIFOLIACEAE Juss.  Weigela Thunb.  CORNACEAE Bercht. ex J. Presl.  Cornus  L. C. sericea  L. • CUCURBITACEAE

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).
