Lasioglossum (Dialictus) cembrilacus Gardner & Gibbs 2020, sp. nov.

Lasioglossum (Dialictus) cembrilacus sp. nov. urn:lsid:zoobank.org:act: 082AC082-F9FB-47A1-9779-9867AF24F57D Figs 19–21, 92B Diagnosis Females of Lasioglossum cembrilacus sp. nov. can be easily recognized by the body mostly covered in extremely dense, long, yellowish, plumose hairs and tomentum, mesothorax shiny and densely punctate (i ≤ 1 pd), face relatively long (length/width ratio ~0.84), and metasomal terga sometimes with metallic green reflections. They are most similar to Lasioglossum albohirtum (Crawford, 1907) (see Gibbs 2010 for a redescription of this species). Females of L. albohirtum have the hair of the paraocular area shorter and sparser, scutum slightly more sparsely punctate (i= 1–2 pd), and metasoma and clypeus apical margin never red or orange. Males of L. cembrilacus sp. nov. can be recognized by the tomentum long and dense in the lower paraocular area and absent or very sparse over the rest of the body, red or orange colouration largely absent except on ventral surface of flagellum, propodeum dorsolateral slope shiny and distinctly punctate, flagellomeres relatively long (F2 about 2 times as long as F1), mesepisternum and metasomal terga relatively densely punctate (i ≤ 1 and i= 1–2 pd, respectively), and metasomal terga with weak metallic green reflections at least in basal half of T1. They are most similar to L. zephyrus (Smith, 1853), L. pictum, and L. decorum sp. nov. Males of L. zephyrus and L. pictum have the propodeum dorsolateral slope rugulose and face with more extensive tomentum. Males of L. decorum sp. nov. have the flagellomeres relatively short (F2 about 1.5 times as long as F1), face without tomentum, frons dull, and mesepisternum and metasomal terga more sparsely punctate (i= 1–2 and 1–4 pd, respectively). Etymology The specific epithet cembrilacus is formed from the New Latin noun ‘ cembra ’ (‘timber’, especially in reference to the tree Pinus cembra L.) plus the Latin genitive noun ‘ lacus ’ (lake; spelled identically in both nominative and genitive case). It is both a dedication to Philip Hunter Timberlake, and a reference to this species’ mountain habitat with its many pines and lakes. An appropriate translation would be Timberlake’s sweat bee.
