Diagnosis
Females of L. tegulare have the tegula relatively small (reaching but not exceeding posterior margin of mesoscutum in dorsal view), with inner posterior margin weakly concave and a narrowly rounded posterior projection smaller than 0.5 OD, and densely (IS <1 PD) to moderately densely punctate (IS = 1–2 PD); mesoscutum and mesepisternum very dull, strongly tessellate, imbricate, or rugulose; mesepisternum punctures crowded (IS = 0 PD) and indistinct; metapostnotum with strong, coarse rugae reaching posterior margin and covering propodeum dorsolateral slope, shiny in basal half; face short (length/width ratio usually ≤ 0.83); T2–T4 flat in lateral view; T3 without subapical tomentum; and head and mesosoma usually olive green.
Females of L. tegulare are most similar to those of L. coactus, L. ellisiae, L. holzenthali sp. nov., and L. puteulanum. Females of L. coactus have T2–T4 convex in lateral view and T3 with dense and complete subapical band of tomentum. Females of L. ellisiae have the mesepisternum punctures distinctly separated and round, and the mesoscutum posterior half and mesepisternum often shiny. Females of L. holzenthali have the mesepisternum punctures distinctly separated (up to 1 PD) and metapostnotum rugae not extending onto propodeum dorsolateral slope. Females of L. puteulanum have the face longer (length/width ratio usually> 0.83), tegula more sparsely punctate (IS = 1–2 PD, closer to 2 PD), and head and mesosoma usually blue (rarely olive green).
Males of L. tegulare have the tegula relatively small (as in the female); mesoscutum relatively coarsely and moderately densely punctate (IS = 1–2 PD); metapostnotum shiny with strong subparallel rugae; discs of T1–T2 and premarginal line uniformly densely punctate (IS ≤ 1 PD); face with sparse tomentum below eye emargination, more concentrated in paraocular area; and head and mesosoma usually olive green.
Males of L. tegulare are most similar to those of L. coactus, L. ellisiae, and L. puteulanum. Males of L. coactus have the discs of T1–T3 even more densely punctate (IS <1 PD) and strongly convex, and apical rims abruptly and deeply depressed. Males of L. ellisiae have the mesoscutum usually more finely and densely punctate laterally (IS <1 PD) and disc of T2 becoming more sparsely punctate near and on premarginal line (IS = 1–2 PD). Males of L. puteulanum have the face below eye emargination evenly covered in tomentum, tegula more sparsely punctate (IS = 1–3 PD), and the head and mesosoma usually blue to blue-green.
Etymology
Robertson (1890) formed the specific epithet ʻ tegularis ʼ from the Latin noun ʻ tegula ʼ (roof tile, literally ʻcovering instrumentʼ, now applied to the sclerite covering the wing base), and the adjectival suffix ʻ -aris ʼ (of or pertaining to).

DNA barcodes
Twenty-three confirmed sequences available (BOLD process IDs: DIAL091-06, DIAL485-06, DIAL490- 06, DIAL491-06, DIAL493-06, DIAL495-06, DIAL518-06, DIAL683-06, DIAL684-06, DIAL742-06, DIAL743-06, DIAL744-06, DIAL745-06, DIAL824-06, DIAL1050-06, DIAL1051-06, DLII061-06, DLII468-07, DLII1300-08, DLII1331-08, DLII1356-08, DLII1545-09, LASNA006-08). There is a large amount of divergence within these sequences (1.58% maximum intraspecific p-distance). They are closest in terms of p-distance to L. puteulanum (0.31% minimum interspecific p-distance). No fixed nucleotide substitutions distinguish L. tegulare from all other species of the L. gemmatum complex or closely related species.
Comments
Robertson (1890) included Montana, California, and Mexico specimens in the type series. These must constitute other species in the L. gemmatum complex, but were not examined in this study. Cresson (1928) subsequently designated a Connecticut specimen from the type series as the name-bearing type.
