description: <i>Baeocera pulchella</i> Fierros-López new species (Figs. 1–6) DIAGNOSIS: This species can be distinguished by the elytra with a transversal fascia, in addition to the following combination of characters: body elongate, slightly compressed laterally; third antennal segment shorter than fourth; scutellum covered by pronotal lobe; basal stria of elytron interrupted at humeral area; mesepimeron as long as most of the anapleural line; mesocoxal line parabolic; aedeagus symmetrical basal portion subequal in length to apical portion; apex of median lobe acute, slightly curved upright; parameres slender and slightly curved. DESCRIPTION: Length 1.7 mm. Coloration: Body ocherous, apical portion of pronotum lighter, elytron cream, with transverse red-brown fascia in middle of disc. Head: spherical, polished, shiny, with few punctures, clypeus with two lateral groups of whitish setae. Antenna (Fig. 1) with second segment about same length as third and fourth combined; third and fourth segments subequal in length. Thorax: pronotum trapezoidal, wider at base, lateral borders with carina; inflexed at basal angles. Disc surface polished with few scattered punctures; microsculpture obsolete, at 50 magnification; scutellum hidden by pronotal lobe. Elytra elongated (Fig. 2), widest at middle; basal stria interrupted at humeral area; discal punctuation more scattered than on pronotum; microsculpture obsolete; epipleura smooth, shining; metacoxal line parabolic (Fig. 3), basal pits rounded, not extended laterally; mesepimeron long, covering almost all anapleaural line; mesosternum sparsely punctured; metasternum laterally widened near apex, surface with few punctures bearing decumbent setae; ventral area ornamented with punctures and setae; metepisternon wide, slightly widened at apex. Legs: long, slender; first three protarsomeres slightly expanded laterally, with abundant setae on ventral surface; mesotarsus with ventral setae. Abdomen: conical, with scattered punctures and few setae; microsculpture not evident; first visible ventrite with basal pits rounded, not expanded laterally. Aedeagus (Figs. 4–6): length 0.49mm, symmetric, basal area bulbous, subequal in length to apical, apex of median lobe pointed, upright curved; internal sac with basal oval sclerite, flagellum with laminar ornamentation; parameres elongated, wider at apex, shorter than median lobe. ETYMOLOGY: The specific epithet name derives from the Latin word <i>pulchella</i> meaning ‘‘beautiful’’ and little, in reference to small size and showy coloration of this species. TYPE LOCALITY: El Floripondio, Municipality San Gabriel, Jalisco. DISTRIBUTION: Known only from Jalisco, México BIONOMICS: This species was collected in a fir-oak forest and cloud forest, by fogging rotten logs with sporophores of <i>Trichia</i> and <i>Poria</i>; other scaphidiinae beetles associated were <i>Baeocera gutierrezberaudi</i>, <i>Scaphisoma opochtli</i> Fierros-López and one unidentified species of <i>Toxidium</i>. VARIATION: (7 males, 1 female). — length: male 1.7–1.92 mm, average (avg.) 1.8 mm, standar devation (stdv) ± 0.1 mm, female 1.86 mm; pronotum: male 0.62–0.7 mm, avg. 0.7 mm ± stdv. 0., female 0.68 mm; elytra: male 1.12–1.3 mm, avg. 1.2 mm, stdv ± 0.1 mm, female 1.18 mm. Elytral maculation varied in intensity and shape, from a wide transverse fascia to a small spot on the disc.
