[sə′laf·ə‚dē]
(invertebrate zoology)
The ant-loving beetles, a large family of coleopteran insects in the superfamily Staphylinoidea.

Pselaphidae

 

a family of polyphagous beetles. The body, which is 3–5 mm long, ranges in color from yellow to brown. The antennae are long and clavate, and the elytra are shortened. The legs are three-jointed and have a single claw. There are two subfamilies, embracing approximately 4,000 species. Ninety species are found in the USSR. Beetles of the subfamily Pselaphinae have eyes and highly developed palpi on the lower jaws; they feed on decomposing matter. Beetles of the subfamily Clavigerinae have no eyes, and their palpi are incompletely developed. They live in anthills, where the ants feed them and then collect secretions from the abdominal glands of the beetles.

Para el caso de la subfamilia Aleocharinae y algunas morfoespecies de Pselaphinae y Paederinae estas fueron determinadas a nivel de subfamilia y tribu respectivamente, debido a la dificultad taxonomica de estos grupos.
Las subfamilias mas representativas en cuanto a riqueza de especies fueron Aleocharinae (25,3%), Pselaphinae (17,7%), Staphylininae (15,2%), Paederinae (12,6%), Oxytelinae (10,1%), Osoriinae (8,9%), Tachyporinae (7,6%) y Euasthetinae (1,3%).
De este modo, Aleocharinae, Pselaphinae, Staphylininae y Paederinae, que en orden son las subfamilias con mayor numero de especies descritas mundialmente (NAVARRETE-HEREDIA et al.
Se observaron especies dominantes de las subfamilias Tachyporinae (Copropoms spl), Osoriinae (Aneucamptus spl, Holotrocluis spl), Oxytelinae (Anotylus spl) y Pselaphinae (Jubini sp7).
Scolytinae, Platypodinae, Pselaphinae and Scaphidiinae).
Three families (Cerambycidae, Cleridae and Coccinellidae) were both more abundant and species rich in the canopy than near the ground, and four other groups (Carabidae, Pselaphinae (Staphylinidae), Scolytinae (Curculionidae) and other Staphylinidae) were both more abundant and species rich near the ground than in the canopy (Tables 4, 5).
The error rate in species sorting was estimated by a comparison of species sorting of Pselaphinae (Staphylinidae) by the authors with a check by a specialist in this group.
Dominant beetle families in the assemblage were Staphylinidae (particularly the subfamilies Pselaphinae, Aleocharinae, Paederinae, and Osoriinae), Scydmaenidae, Ptiliidae, and Curculionidae (particularly Scolytinae and Curculioninae), with 50-150 species each (Appendix A).
This genus is named for a world-renown beetle specialist and one of the most influential specialists of Pselaphinae during modern time, Donald S.
Las subfamilias mas abundantes fueron Aleocharinae (69,6%), Staphylininae (15,3%), Pselaphinae (4,7%), Osoriinae (3,6%) y Tachyporinae (3,1%); aunque estos porcentajes cambian cuando se observa la riqueza de especies en las subfamilias, siendo Aleocharinae (33,6%) la mas rica, seguida de Staphylininae (21,3%), Pselaphinae (14,7%) y Paederinae (13,1%).
De manera similar, los resultados obtenidos en el estudio de Gutierrez-Chacon y Ulloa-Chacon (2006), en tres localidades de la cordillera occidental, se registraron 11 subfamilias y 293 morfoespecies encontrandose una proporcion similar, pero en este ultimo caso la subfamilia Pselaphinae estuvo en segundo lugar de riqueza debido al tipo de muestreo (sacos Winkler), con los cuales se recolecta una mayor proporcion de artropodos de hojarasca (Olson 1994).
