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

Lasioglossum (Dialictus) indagator sp. nov. urn:lsid:zoobank.org:act: D5070EC1-B6A9-49D4-9C68-7D03A6BE5BCD Figs 36–38, 76I, 84B, 105B Diagnosis Females of L. indagator sp. nov. have the tegula relatively small (reaching but not exceeding posterior margin of mesoscutum in dorsal view), with inner posterior margin weakly concave, with a gentle S-shaped curve and blunt posterior angle, and moderately sparsely punctate laterally at midlength (IS = 1–3 PD); mesoscutum lateral and posterior margins, metanotum, and pleura with abundant tomentum; mesoscutum, scutellum, and mesepisternum shiny and densely punctate (IS ≤1 PD) (mesoscutum becoming tessellate and more sparsely punctate anteromedially (IS = 1–2 PD)); metapostnotum with subparallel rugae not reaching posterior margin; T1 anterior slope coriarious; gena subequal to or slightly wider than eye in lateral view; and tegula and metasoma red-orange. Females of L. indagator sp. nov. are most similar to those of L. diabolicum sp. nov., L. ellisiae, L. gaudiale, and L. gloriosum sp. nov., all of which (except L. gloriosum) have the mesoscutum, metanotum, and pleura with tomentum sparse or absent, and all except L. gaudiale have the metapostnotum rugae reaching the posterior margin. In addition, females of L. gaudiale have the T1 anterior slope shiny and scutellum often sparsely punctate (IS = 1–2 PD). Females of L. gloriosum have the tegula larger (exceeding posterior margin of mesoscutum in dorsal view) and densely punctate (IS ≤ 1 PD). Females of L. diabolicum have the gena slightly narrower than the eye in lateral view. Males of L. indagator sp. nov. have the tegula relatively small (at most slightly exceeding posterior margin of mesoscutum in dorsal view), with inner posterior margin weakly concave and a blunt posterior angle, and usually moderately sparsely punctate in part (IS = 1–2 PD); face broad (length/width ratio ≤0.83) and covered with very dense tomentum up to the median ocellus; mesoscutum usually moderately densely punctate (IS = 1–2 PD) and fringed with tomentum; pleura with extensive tomentum; metapostnotum shiny with strong, short rugae not reaching the posterior margin; T2–T3 with extensive basolateral tomentum; and head and mesosoma usually blue to blue-green. They are most similar to those of L. gaudiale and L. gloriosum sp. nov. See the diagnosis for L. gaudiale for a comparative diagnosis between these three species. Etymology The specific epithet ʻ indagator ʼ is a noun derived from the Latin verb ʻ indago ʼ (to hunt, chase) and the suffix ʻ -ator ʼ (implying action or agency). It means ʻhunterʼ and refers to the fact that most specimens were identified as L. hunteri in the past.
