Diagnosis
Females of L. coactus have T1–T3 distinctly convex in lateral view (although not as strongly so as in the male), with apical rims strongly depressed, shiny, and impunctate or very sparsely punctate, contrasting with densely punctate discs (IS ≤ 1 PD); T3 with dense and complete subapical band of tomentum; tegula relatively small (reaching but not exceeding posterior margin of mesoscutum) and densely punctate (IS ≤ 1 PD); metapostnotum usually shiny with strong anastomosing rugae reaching posterior margin (rarely dull with fine rugae); mesepisternum imbricate with punctures often dense (IS <1 PD) but distinctly separated and round (sometimes crowded (IS = 0 PD)); and inner metatibial spur with 3–4 branches.
Females of L. coactus are most similar to those of L. carlinvillense and L. tegulare, both of which have T1–T3 flat in lateral view. In addition, females of L. carlinvillense have the inner metatibial spur with only 2 branches and L. tegulare have the mesepisternum with crowded indistinct punctures (IS = 0 PD) or rugulose. Some species in the L. stictaspis species complex (particularly L. stictaspis s. str.) are also similar, but have T1–T3 flat in lateral view and more finely and sparsely punctate (IS = 1–3 PD), the mesepisternum shiny, and/or metapostnotum dull with fine, subparallel rugae.
Males of L. coactus have T1–T4 very strongly convex, with abruptly depressed, shiny, impunctate apical rims contrasting with densely punctate discs (IS <1 PD); tegula relatively small (reaching but not exceeding posterior margin of mesoscutum in dorsal view), with inner posterior margin weakly concave, and somewhat densely punctate (IS ≤1 PD); and mesepisternum densely punctate (IS <1 PD). They are not likely to be confused with any other species so long as T1–T4 are visible, but specimens with broken metasomas may be indistinguishable from L. tegulare.
Etymology
The specific epithet ʻ coactus ʼ could be either a Latin noun (compulsion, constraint) or a perfect participle (forced, compelled). Because Cresson (1872) did not specify the intended grammar, according to Article 31.2.2 of the International Code of Zoological Nomenclature (ICZN 1999), the epithet is treated as a noun and is therefore not declinable to ʻ coactum ʼ in combination with ʻ Lasioglossum ʼ, as has been done in the past.

DNA barcodes
Eight confirmed sequences available, two haplotypes (BOLD process IDs: BWTWO1314-10, DLII051- 06, LASNA016-08 (haplotype 1); DIAL1132-07, DLII307-07, DLII318-07, DLII338-07, DLII547- 07 (haplotype 2)). Haplotype 1 is very similar to L. carlinvillense, and haplotype 2 is very similar to L. tegulare. There is a large amount of divergence within these sequences (3.36% maximum intraspecific p-distance). They are closest in terms of p-distance to L. carlinvillense (0.15% minimum interspecific p-distance). No fixed nucleotide substitutions distinguish all L. coactus from all other Nearctic species of the L. gemmatum complex, but one fixed substitution distinguishes haplotype 1, and two fixed substitutions distinguish haplotype 2: 156(C) (haplotype 1); 429(G) and 441(C) (haplotype 2) (Supp. file 2).
