( Figs 1 View FIGURES 1–4 , 5 View FIGURES 5–8 )

Lomachaeta argenta Pitts & Manley, 2004: 5   . Holotype, ♀, USA, Utah, Washington Co. (EMUS). Pitts & Manley (2004): Hosts.

Diagnosis. FEMALE. This species can be recognized by its setal distribution and body shape: the mesosoma and T2 have matching subparallel subappressed long silver to golden setae and the dorsal thoracic length is 0.85 × its width. The following characters may also aid in diagnosis: the head width is subequal to the mesosomal width; the baso-ventral mandibular margin lacks a hyaline lamella; the pronotal spiracle is only weakly swollen; the lateral mesonotal tooth is distinct; the propodeal spiracle is slightly more sharply swollen than the pronotal spiracle; the mesonotal dorsum has about 12 areolations between the pronotal spiracles; the T1 shape is sub-disciform; T2 has dense punctures and mostly smooth intervals; the fringes of T2–3 are composed of dense setae thicker than the erect setae surrounding them; and the S6 lateral carina is small and sharply triangular. Body length 3–3.5 mm.

MALE. Unknown.

Boehme (1♀, EMUS)   ; Utah, Washington County , 3 mi W Hurricane, reared, F. D. Parker (1♀, paratype, EMUS, Figs 1 View FIGURES 1–4 , 5 View FIGURES 5–8 )   .

Distribution. Known from the Great Basin, Mojave Desert, and the Arizona Mountains forests in Arizona, Nevada, and Utah, USA.

Remarks. This species, formerly recognized from one Great Basin locality in southern Utah, is newly recorded from Arizona and Nevada in two additional ecoregions. The newly identified specimens from Arizona were collected from trap nests that also included L. crocopinna   , L. cirrhomeris   , and L. hicksi   . Since the females of L. hicksi   and L. cirrhomeris   are already known, L. crocopinna   could be the unknown male of L. argenta   . These specimens, however, are far removed from the type locality of L. crocopinna   , so we prefer to wait for more evidence before formalizing this synonymy.
