Diagnosis

Females of L. gaudiale have the tegula relatively small (reaching and sometimes slightly exceeding posterior margin of mesoscutum in dorsal view), with inner posterior margin strongly concave and a small rounded posterior projection, and usually densely punctate (IS ≤ 1 PD, rarely up to 2 PD); T1 anterior slope polished and mirror-smooth (rarely with very weak microsculpture basally); gena about as wide as eye in lateral view; metapostnotum usually shiny basally with strong subparallel rugae not reaching the posterior margin (sometimes dull, with rugae anastomosing, or rugae reaching posterior margin, but never all at once); mesoscutum with no tomentum; T3 without a subapical band of tomentum; and metasoma usually black to brown (rarely red-orange). In many cases, the scutellum is significantly more coarsely and sparsely punctate than the mesoscutum (IS = 1–2 PD), but this is unreliable as a primary diagnostic character.

Females of L. gaudiale are most similar to those of L. angelicum sp. nov., L. eremum sp. nov., L. gloriosum sp. nov., L. indagator sp. nov., and L. pseudotegulare , all of which (except L. indagator ) have the gena narrower than eye in lateral view and scutellum usually finely and densely punctate (IS <1 PD). In addition, females of L. eremum sp. nov. have the metapostnotum with anastomosing rugae reaching the posterior margin and T1 anterior slope coriarious. Females of L. gloriosum have the T1 anterior slope coriarious, mesoscutum lateral and posterior margins with dense tomentum, metapostnotum rugae usually reaching the posterior margin, and metasoma red-orange. Females of L. indagator have the tegula sparsely punctate (IS = 1–3 PD) and inner posterior margin weakly concave. Females of L. pseudotegulare have the metapostnotum entirely dull with fine rugae and tegula very large (exceeding posterior margin of mesoscutum in dorsal view) and more densely punctate (IS <1 PD). Females of L. angelicum sp. nov. have a similarly large tegula.

Males of L. gaudiale have the tegula relatively small (reaching or slightly exceeding posterior margin of mesoscutum in dorsal view), with inner posterior margin strongly concave and a narrow posterior point, and usually densely punctate (IS <1 PD); face relatively narrow (length/width ratio usually>0.83) with dense tomentum below the upper ocular tangent (often surrounding the median ocellus); metapostnotum usually shiny with strong subparallel rugae not reaching posterior margin; mesoscutum usually densely punctate (IS ≤ 1 PD) and fringed with tomentum; mesepisternum somewhat coarsely punctate with distinct interspaces (IS ≤1 PD); preëpisternum and metepisternum with sparse appressed tomentum; T2–T3 with abundant basolateral tomentum; and head and mesosoma integument usually deep blue.

Males of L. gaudiale are most similar to those of L. gloriosum sp. nov. and L. indagator sp. nov. Both of these species have the face broad (length/width ratio ≤ 0.83) and preëpisternum and metepisternum with more abundant tomentum. In addition, males of L. gloriosum have the mesepisternum very densely punctate (IS <1 PD); metapostnotum usually with anastomosing rugae reaching posterior margin; and integument usually greener. Males of L. indagator have the metapostnotum with very short parallel rugae not reaching the posterior margin; tegula inner posterior margin more weakly concave, forming a blunt angle posteriorly, and usually moderately sparsely punctate laterally (IS = 1–2 PD); and mesoscutum usually slightly more sparsely punctate (IS = 1–2 PD).

Etymology

Sandhouse (1924) formed the specific epithet ʻ gaudialis ʼ from the Latin noun ʻ gaudium ʼ (joy) and the adjectival suffix ʻ -alis ʼ (state or condition of), together meaning ʻjoyfulʼ.

DNA barcodes

Twelve confirmed sequences available, two haplotypes (BOLD process IDs: BEECB223-07, BEECB225-07, BEECB226-07, DLII648-07, NCBEE405-21, NCBEE406-21, NCBEE617-21 (haplotype 1); DLIII156-19, DLIII226-20, DLIII228-20, DLIII229-20, DLIII230-20 (haplotype 2)). There is a large amount of divergence within these sequences (2.61% maximum intraspecific p-distance). They are closest in terms of p-distance to L. helianthi (1.07% minimum interspecific p-distance). No fixed nucleotide substitutions distinguish all L. gaudiale from all other Nearctic species of the L. gemmatum complex, but two fixed substitutions distinguish haplotype 1, and two fixed substitutions distinguish haplotype 2: 205(C) and 357(C) (haplotype 1); 408(A) and 411(T) (haplotype 2) (Supp. file 2).

Comments

Common in Nevada and California , becoming rare further east. Lasioglossum gaudiale is especially abundant in the Mojave Desert.
