description: <i>Baeocera gutierrezberaudi</i> Fierros-López new species (Figs. 7–12) DIAGNOSIS: this species can be easily recognized by maculated elytra and the following combination of characters: scutellum exposed at apex; basal stria complete; mesocoxal line parallel; mesepimeron covering <b>L</b> of anapleural line; aedeagus symmetrical; basal portion longer than apex; apical portion of median lobe acute, extendind behind tip of median lobe. DESCRIPTION: Length 1.8 mm. Coloration: head, pronotum, venter of thorax, median area of femora, tibia and basal segments of abdomen brownish black; apex of femora, tibia, tarsus, first two segments of antennae, area between antennal insertions and hypomeron ochreous; elytra yellow with a irregular black spot on disc, sutural border dark brown; apical segments of abdomen brown with lighter apex. Head: spherical, shiny, with few scattered punctures and some whitish setae. Antennae filiform (Fig. 7); second segment little longer than third; third segment longer than fourth. Thorax: pronotum trapezoidal, wider at base; lateral borders with carinae; disc surface smooth, shiny, with scattered punctures; microsculpture scattered at 50X magnification; scutellum almost completely covered by pronotal lobe; elytron rectangular (Fig. 8), widest near the middle; basal stria complete, joining lateral stria; punctures strong and more abundant compared to those of pronotum; mesocoxal line parallel (Fig. 9), basal pits rounded, not extended laterally; mesepimeral length about <b>L</b> of anapleural line; mesosternum polished; metasternum with lateral area widened, with few punctures and setae, ventral area with abundant punctures bearing setae; metepisternum wide, weakly widened at apex; legs elongated, first three basal tarsomeres slightly expanded laterally, with abundant ventral setae; mesotarsomeres with ventral setae. Abdomen: conical, with few punctures and ventral setae; microsculpture not evident; first visible ventrite with basal pits elongated; aedeagus (Figs. 10–12): length 0.77 mm symmetrical, basal portion of median lobe bulbous and longer than apical, apex acute, abruptly curved upright; inner sac with basal irregular filamentous sclerites; apical portion of internal sac with transversal rows of denticles; parameres extended behind tip of median lobe; slightly curved toward apex, in lateral view, widened subapically. ETYMOLOGY: This species is named in honor to Gerardo Gutierrez-Beraud, enthusiastic entomologist interested in dermestids, talented writer and excellent friend. TYPE LOCALITY: El Floripondio, San Gabriel, Jalisco, Mexico. DISTRIBUTION: known only from the type locality in Jalisco, México. BIONOMICS: the species was found in oak-fir cloud forest, using the collecting method of fogging rotting logs, in association with sporophores of <i>Ganoderma australe</i> and unidentified species of <i>Poria</i> and <i>Trichia</i>; other scaphidiinae beetles associated with this species were <i>Baeocera pulchella</i>, <i>Scaphisoma opochtli</i> Fierros- López, and one undetermined species of <i>Toxidium</i>. VARIATION: (6 males, 10 females). Length: male 1.68–1.88 mm, avg. 1.8 mm, stdv. ± 0.1; female 1.6–1.84 mm, avg. 1.7 mm, stdv. ± 0.1 mm. Pronotum: male 0.58– 0.66 mm, avg. 0.6, stdv. ± 0 mm, female 0.58–0.7 mm, avg. 0.6, stdv ± 0 mm. Elytra: male 1.02–1.24 mm, avg. 1.2 mm, stdv, ± 0.1 mm, female 1–1.2 mm, avg. 1.1 mm, stdv. ± 0.1 mm. Elytral maculation varies in shape from a rectangular fascia with regular borders to irregular spots with extensions.
