Diagnosis
Females of L. ellisiae have the tegula somewhat small (reaching and sometimes slightly exceeding posterior margin of mesoscutum in dorsal view), relatively sparsely punctate laterally at midlength (at least IS = 1 PD, up to IS = 1–3 PD), and inner posterior margin weakly concave, with a gentle S-shaped curve coming to a narrow rounded point posteriorly; mesepisternum punctures distinct, round, and about as fine and dense as those of hypoepimeron; metapostnotum shiny with coarse rugae reaching posterior margin; mesoscutum and mesepisternum usually shiny or with weak microsculpture; T1 anterior slope coriarious; T3 without subapical band of tomentum (rarely with some sparse tomentum apicolaterally); and tegula and metasoma sometimes red-orange.
Females of L. ellisiae are most similar to those of L. diabolicum sp. nov., L. gaudiale, L. indagator sp. nov., and L. tegulare. Females of L. diabolicum have the tegula slightly smaller (often not reaching posterior margin of mesoscutum in dorsal view) with inner posterior margin usually straight and metapostnotum usually dulled by strong microsculpture. Females of L. gaudiale have the T1 anterior slope shiny with microsculpture absent or very weak and the tegula inner posterior margin more strongly concave. Females of L. indagator have the metapostnotal rugae usually not reaching posterior margin and more extensive tomentum on the mesoscutum lateral and posterior margins, metanotum, and pleura. Females of L. tegulare have the mesoscutum and mesepisternum entirely dull with strong microsculpture and mesepisternum with crowded punctures (IS = 0 PD) some of which are not distinctly round. Some other species in the L. stictaspis species complex (particularly L. stictaspis s. str.) can also be very similar, but have the mesepisternum punctures larger and slightly sparser than those of hypoepimeron, mesoscutum more irregularly and sparsely punctate (as in L. diabolicum), tegula inner posterior margin usually more strongly concave and usually more densely punctate (IS ≤ 1 PD), metapostnotum usually dull with fine rugae, and T3 usually with dense and complete subapical band of tomentum.
Males of L. ellisiae have the tegula somewhat small (as in the female); metapostnotum usually shiny with strong subparallel rugae; mesoscutum between parapsidal lines uniformly densely punctate (IS ≤ 1 PD); and discs of T2–T3 becoming more sparsely punctate on premarginal line, not contrasting with impunctate apical rims (punctures in basal half of T2–T3 may be deep and dense (IS ≤ 1 PD) or fine and moderately sparse (IS = 1–2 PD)).
Males of L. ellisiae are most similar to those of L. diabolicum sp. nov., L. lepidii, L. puteulanum, and L. tegulare. All of these species have the mesoscutum more irregularly and slightly more sparsely punctate between the parapsidal lines (some IS <1 PD and some IS = 1–2 PD). Males of L. diabolicum and L. lepidii have the disc of T2 uniformly finely and moderately sparsely punctate (IS = 1–2 PD). In direct comparison, males of L. lepidii also have the facial tomentum denser and more tightly appressed (more completely obscuring the surface underneath) and the mesothoracic spiracle more deeply impressed. Males of L. puteulanum and L. tegulare have the disc of T2 uniformly deeply and densely punctate (IS ≤ 1 PD) including the premarginal line. Some other species in the L. stictaspis species complex can also be very similar, but have the tegula slightly larger, with inner posterior margin more strongly concave, and more often entirely densely punctate (IS <1 PD) and mesoscutum more irregularly and sparsely punctate (as above).
Etymology
Sandhouse (1924) dedicated this species to her fellow bee taxonomist Marion Durbin Ellis.

DNA barcodes
Nineteen confirmed sequences available (BOLD process IDs: BEECB221-07, BOWGF1482-10, BWTWO897-10, BWTWO899-10, BWTWO902-10, DIAL476-06, DIAL888-06, DIAL918-06, DIAL1089-06, DLII031-06, DLII1522-09, DLII1527-09, DLII1559-09, DLII1566-09, DLII1586-09, DLII1590-09, DLIII026-09, DLIII122-18, NCBEE387-21). There is a moderate amount of divergence within these sequences (0.76% maximum intraspecific p-distance). They are closest in terms of p-distance to L. helianthi (1.22% minimum interspecific p-distance). Two fixed nucleotide substitutions distinguish L. ellisiae from all other Nearctic species of the L. gemmatum complex: 312(A) and 573(C) (Supp. file 2).
Comments
Specimens of L. ellisiae from the southwestern parts of its range usually have the tegula and metasoma red-orange and have been considered a separate species, L. hunteri, in the past. However, the geographical boundaries of the dark forms and red-tailed forms are very fuzzy. Dark specimens of L. ellisiae are known from New Mexico and Colorado, and red-tailed specimens have been found as far north as Minnesota and Manitoba. No other morphological features can distinguish the two forms; if colour is disregarded, the holotype of L. hunteri is a typical L. ellisiae. An apparent distribution gap between eastern and western specimens (Fig. 20) is likely due to undersampling in eastern South Dakota, eastern Nebraska, eastern Kansas, Oklahoma, and Missouri. DNA barcodes from across the range of L. ellisiae, including red-tailed specimens from Texas and Minnesota, are indistinguishable. No line of evidence can support the hypothesis that L. hunteri is a distinct species.
Four unusual red-tailed specimens from southern Texas have the metapostnotum completely dull, smooth, and lacking rugae, even fine ones, in the apical 75%, but otherwise resemble typical L. ellisiae. The identification of these specimens is somewhat uncertain. They are tentatively included in L. ellisiae as the closest available match and because there is no additional evidence to support consideration of these specimens as a new species.
