Lasioglossum (Dialictus) pseudotegulare

Lasioglossum (Dialictus) pseudotegulare (Cockerell, 1896) Figs 51–53, 76M, 88A, 89A, 108B, 111A, 112A Halictus pseudotegularis Cockerell, 1896: 294 (holotype, ♀, deposited in USNM, examined). Halictus pseudotegularis – Cockerell 1899: 5 (catalogue). Halictus (Chloralictus) pseudotegularis – Sandhouse 1924: 2, 8 (key to species), 11 (comparison to ellisiae). — Ellis 1914: 101 (comparison to jamaicae = gemmatum). Lasioglossum (Chloralictus) pseudotegulare – Michener 1951: 1117 (catalogue). Dialictus pseudotegularis – Hurd 1979: 1970 (catalogue). — Moure & Hurd 1987: 125 (catalogue). Diagnosis Females of L. pseudotegulare have the face relatively long (length/width ratio usually ≥0.83); tegula large (maximum length usually more than half ITS and reaching or exceeding posterior margin of mesoscutum in dorsal view), densely punctate (IS <1 PD), and with inner posterior margin strongly concave and a rounded posterior projection 0.5–1 OD in size; metapostnotum finely reticulate with shallow subparallel rugae; mesepisternum shiny with at most weak microsculpture; mesoscutum with dense erect pubescence (each seta less than its length from the one nearest it and no gaps more than 0.5 OD visible in lateral view) and short intervening setae 0.25 OD long or more; disc of T4 with sparse tomentum; mesoscutum concolourous with propodeum; apical rims of T1–T2 sometimes distinctly punctate (especially in Sonoran Desert specimens), and gena narrower than eye in lateral view. Females of L. pseudotegulare are most similar to those of L. angelicum sp. nov., L. gaudiale, and L. magnitegula sp. nov. Females of L. angelicum have the metapostnotum shiny with strong anastomosing rugae and face slightly shorter (length/width ratio ≤ 0.83). Females of L. gaudiale have the gena about as wide as eye in lateral view, metapostnotum usually shiny, and tegula with a posterior point narrower than 0.5 OD. Females of L. magnitegula have the mesoscutum with sparse erect pubescence (each seta about its length from the one nearest it) and very short intervening setae no more than stubble, T4 without tomentum, mesoscutum more greenish, golden, or reddish, contrasting with bluer propodeum, and apical rims of T1–T2 impunctate. Males of L. pseudotegulare have the face relatively long (length/width ratio usually> 0.86); tegula large (as in the female); mesepisternum densely punctate (IS <1 PD); metapostnotum tessellate to finely reticulate with shallow subparallel rugae; discs of T1–T2 deeply, distinctly, and densely punctate (IS ≤ 1 PD); T1–T2 apical rims with numerous deep, dense punctures basolaterally (IS ≤1 PD); and head and mesosoma uniformly coloured. Males of L. pseudotegulare are most similar to those of L. angelicum sp. nov. and L. magnitegula sp. nov. Males of L. angelicum have the face shorter (length/width ratio ≤0.86) and discs of T1–T3 more sparsely punctate (IS = 1–2 PD). Males of L. magnitegula have the T1–T2 apical rims impunctate and mesoscutum with a more greenish or golden tint, contrasting with the bluer propodeum. In direct comparison, the mesosoma punctures are somewhat larger and coarser in L. magnitegula than in L. pseudotegulare. A similar, undescribed species only known from Veracruz may be confused with L. pseudotegulare, but can be separated in both sexes by the metapostnotum shiny with strong rugae and tegula usually orange (dark brown in L. pseudotegulare). Some other species in the L. stictaspis species complex can also be very similar in both sexes. Most have the mesepisternum dull or more sparsely punctate (IS = 1–2 PD), metapostnotum with strong anastomosing rugae, or T1–T2 less distinctly punctate, but a few can only be distinguished by a shorter face. Etymology Cockerell (1896) formed the specific epithet ʻ pseudotegularis ʼ from the Greek noun ʻ pseudos ʼ (lie), the Latin noun ʻ tegula ʼ (roof tile, literally ʻcovering instrumentʼ, now applied to the sclerite covering the wing base), and the Latin adjectival suffix ʻ -aris ʼ (of or pertaining to).
