Description of Two New Species of Baeocera Erichson (Coleoptera: Staphylinidae: Scaphidiinae) from México Author López, Hugo Eduardo Fierros- text Journal Of The Kansas Entomological Society 2010 2010-09-30 83 3 201 207 journal article 10.2317/JKES0905.18.1 667e411c-326a-43ca-82ab-ae8c13780339 3483766 Baeocera gutierrezberaudi 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 L 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 L 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 Ganoderma australe and unidentified species of Poria and Trichia ; other scaphidiinae beetles associated with this species were Baeocera pulchella , Scaphisoma opochtli Fierros- López, and one undetermined species of Toxidium . 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.
