Lasioglossum mesillense
Note bits of orange on legs and metasoma, long antennae, short face with eyes strongly converging below, and basolateral tomentum on T2–3.

 
OK
Lasioglossum mesillense (Cockerell, 1898)

I'm finally able to get back on to Discoverlife.org and I'm working on it now. I needed to know exactly where to place the (new) species page in the guide. Thanks For helping!
BOLD has a page for them here. (AZ, CA, NM, UT)
Diagnosis:
Males of L. mesillense can be recognized by the flagellomeres relatively long (F2 about 2 times as long as F1 and 1.6 times as long as broad), face short (length/width ratio ~0.84) and covered in dense tomentum below the ocelli, mesepisternum shiny and moderately densely punctate (i = 1–2 pd), metapostnotum with relatively weak rugae not reaching the posterior margin or extending onto the dorsolateral slope, T2–3 often with basolateral tomentum, and clypeus apical margin and labrum orange to yellow. They are most similar to L. minckleyi sp. nov., L. austerum sp. nov., and L. clematisellum. Males of L. minckleyi sp. nov. have the flagellomeres relatively short (F2 about 1.6 times as long as F1 and 1.25 times as long as broad), frons with crowded and indistinct punctures, and T2–3 never with basolateral tomentum. Males of L. austerum sp. nov. have the flagellomeres relatively short (F2 about 1.75 times as long as F1 and 1.4 times as long as broad) and face with sparse tomentum. Males of L. clematisellum have the clypeus apical margin, labrum, and metasoma black, metapostnotum with strong rugae reaching the posterior margin and extending onto the dorsolateral slope, and T2–3 never with basolateral tomentum.
