Lasioglossum (Dialictus) profundum Gardner & Gibbs 2023, sp. nov.

Lasioglossum (Dialictus) profundum sp. nov. urn:lsid:zoobank.org:act: 733EE382-5F27-440B-A179-DE2D0A166E65 Figs 48–50, 76L, 81A, 82A Diagnosis Females of L. profundum sp. nov. have the tegula very small (maximum length <45% ITS and barely reaching posterior margin of mesoscutum in dorsal view if at all), dark brown, with inner posterior margin straight, and impunctate except on far anterior margin; mesoscutum coarsely punctate (punctures as large as on mesepisternum, but sparser medially (IS = 1–2 PD)); mesoscutum and mesepisternum usually dull, tessellate to imbricate (mesoscutum sometimes shiny posteriorly); metapostnotum shiny with strong, coarse rugae; T1–T3 apical rims finely punctate; T2–T3 with tomentum covering half or more length of segment laterally; and mesoscutum with dense erect pubescence (each seta less than its length from the one nearest it and no gaps more than 0.5 OD wide visible in lateral view) and short intervening setae 0.25 OD long or more. Females of L. profundum sp. nov. are most similar to those of L. deludens sp. nov. and L. rufodeludens sp. nov. See the diagnosis for L. deludens for a comparative diagnosis between these three species. They are also somewhat similar to those of L. holzenthali sp. nov. and L. perparvum, both of which have the tegula with at least some fine punctures medially and T2–T3 with tomentum covering less than half length of segment laterally. In addition, females of L. holzenthali have the T1–T3 apical rims with larger and deeper punctures. Females of L. perparvum have the mesoscutum with sparse erect pubescence (each seta about its length from the one nearest it and some gaps more than 0.5 OD wide visible in lateral view) and very short intervening setae no more than stubble, mesoscutum more finely punctate, and metapostnotum dull with fine rugae. Males of L. profundum sp. nov. have the tegula relatively small (maximum length less than half ITS and not reaching posterior margin of mesoscutum in dorsal view), dark brown, with inner posterior margin weakly concave and a blunt posterior angle, and impunctate except on far anterior margin and sometimes a few punctures on posterior margin; mesoscutum shiny and usually coarsely, moderately densely punctate (IS = 1–2 PD); metapostnotum usually shiny with strong subparallel rugae; face with dense tomentum up to eye emargination and slightly above; mesoscutum with dense erect pubescence (no gaps more than 0.5 OD visible in lateral view); and head and mesosoma usually deep blue. Males of L. profundum sp. nov. are most similar to those of L. deludens sp. nov. and L. rufodeludens sp. nov. See the diagnosis for L. deludens for a comparative diagnosis between these three species. They are also somewhat similar to those of L. holzenthali sp. nov. and L. perparvum, both of which have the face with dense tomentum limited to paraocular area and tegula usually punctate medially (rarely may be impunctate in L. holzenthali). In addition, males of L. holzenthali have the T1–T3 apical rims deeply and distinctly punctate. Males of L. perparvum have the mesoscutum with sparse erect pubescence (some gaps more than 0.5 OD visible in lateral view) and metapostnotum dull with fine rugae. Etymology The specific epithet ʻ profundum ʼ is a Latin adjective meaning ʻdeepʼ or ʻprofoundʼ. It is a reference to this species’ deep blue and brown colouration, deep punctures, and its abundance near the deep caves at Carlsbad Caverns National Park. An appropriate translation would be the deep sweat bee. Material examined Holotype UNITED STATES – Texas • ♀; Brewster Co.; 29.1532° N, 103.1095° W; 30 Apr.; H.W. Ikerd leg.; BBSL USGS-DRO 009757.
