Diagnosis. Anelaphus brummermannae is most easily confused with A. piceus (Chemsak) and A. simile (Schaeffer) due to the similarly small size, uniform coloration, weakly spined antennomeres, coarsely alveolate-punctured pronotum, and posteriorly closed procoxal cavities. It is most easily distinguished by the denser pubescence on the elytra that is mostly semi-translucent golden, suberect and not recurved back toward the elytra. In A. piceus , which it superficially resembles the most due to the usual very dark brown coloration of most specimens of both species, the elytra have pubescence that is mostly short, non-translucent white, recurved, and sparser. The elytra of A. brummermannae lack the longitudinal, glabrous strips that are characteristic of A. piceus . The pronotum of A. piceus has a glabrous, impunctate collar anteriorly, thickest at middle, which is narrow in A. brummermannae . The head of A. piceus lacks long, erect setae unlike in A. brummermannae which has conspicuous long, erect setae on the frons, antennal tubercles, and usually vertex. Anelaphus simile is most similar to A. brummermannae structurally, but most specimens are lighter reddish-brown in color compared to the very dark brown color of all known specimens of A. brummermannae . The elytral pubescence of A. simile ranges from off-white to pale yellow ochre and is mostly short and recurved. The metasternum of A. simile , especially at the sides and anterior margin, is densely, shallowly punctate and usually has pubescence dense enough to hide much of the integument. In A. brummermannae , the metasternum is sparsely, separately punctate, with punctures relatively deep and well-defined and the metasternal pubescence is sparse and does not conceal the integument. The pronotum of A. brummermannae is more quadrate, not rounded at sides and not widest at middle or anterior of middle as in most specimens of A. simile and A. piceus . Additionally, there are aedeagal features of A. brummermannae that differ subtly from A. piceus and A. simile as described below.

Description. Small to moderate sized, 9.5–11.5 mm long; 2.5–3.1 mm broad; integument uniformly dark brown (rarely light brown). Head with combination of mostly appressed, short, semitranslucent golden setae mixed with longer erect setae on the frons, antennal tubercles, and vertex. Interantennal impression weak; antennal tubercles rounded and not strongly elevated. Antennae of male extending beyond elytral apices by one antennomere; shorter than elytra in female ( Fig. 3 View Figure 3 a–b). Last antennomere 1.4 times length of penultimate in male with pronounced constriction at apical third; less than 1.3 times length of penultimate in female and with weak constriction apically. Antennomere four of both sexes slightly shorter than three and five. Antennae with short mesal spine on antennomere 3, very weakly spined to dentiform mesally on antennomere 4. Antennomeres 3–10 moderately produced apicolaterally. Antennae with combination of suberect and appressed semitranslucent, golden setae becoming more dense, shorter, and appressed on antennomeres 6–11. Pronotum nearly quadrate ( Fig. 3c View Figure 3 ), width subequal to length, not rounded at sides, distinctly narrower than base of elytra and slightly narrower than head at widest point; base and apex in most specimens approximately equal width. Pronotum with conspicuous semitranslucent golden pubescence that is sparse, short, recurved, and not concealing punctures. Pronotum covered with contiguous, mostly uniformly sized circular alveolate punctures except on narrow anterior collar and lacking smooth calli. Prosternum with sparse, separate punctures of uniform size and distribution in females; with a patch of denser, smaller punctures anterior to procoxae in males. Prosternal intercoxal process arcuately recessed between procoxae, strongly expanded at apex closing procoxal cavities posteriorly. Elytron with moderately dense, uniformly distributed, semitranslucent golden, suberect pubescence combined with a few scattered erect and subappressed setae ( Fig. 3d View Figure 3 ). Elytral apices rounded to suture, lacking spines or acute angle at suture ( Fig. 3a View Figure 3 ). Elytron with large punctures, dense but mostly non-contiguous at basal half, becoming shallower and ultimately indistinct at apex. Scutellum rounded posteriorly, with very dense, bright white pubescence throughout except for small glabrous basal region. Legs short with pro-, meso-, and metafemora progressively longer; metafemora extending to about apex of third ventrite. Femoral pubescence mostly short, sparse, semitranslucent golden, subappressed but not recurved. Femoral apices rounded mesad and laterad, without spines. Tibiae cylindrical; only slightly enlarged apically. Venter with pubescence consisting of semitranslucent golden, short, sparse setae that do not conceal the mostly separate, small, sparse punctures that are most conspicuous on the metasternum and metepisternum. Last ventrite of both sexes broadly rounded apically, without modification. Apex of eighth tergite ( Fig. 4a View Figure 4 ) moderately impressed at middle; subapical setose ridge and pigmented patch relatively broad and quadrate shaped with long, widely spaced setae; apex of median lobe evenly narrowed; setae on apices of paramere long; parameres with rounded internal openings ( Fig. 4b View Figure 4 ).

Etymology. This species of Anelaphus is named for naturalist and artist, Margarethe Brummermann, who collected most of the known specimens on her property in Picture Rocks, Arizona.

Discussion. Like Anelaphus piceus (Chemsak) , this is an early species with adults flying mostly from early April to late June, before the monsoon rains arrive. All specimens have been collected at lights in Sonoran Desert habitat below 5000 ′. Host plants are unknown.
