JIMENEZ-SANCHEZ, Esteban; ZARAGOZA-CABALLERO, Santiago  and  NOGUERA, Felipe A.. Temporal variation of the diversity of nocturnal staphylinids (Coleoptera: Staphylinidae) in a tropical dry forest in Mexico. Rev. Mex. Biodiv. [online]. 2009, vol.80, n.1, pp.157-168. ISSN 2007-8706.

A study of the temporal variation of the nocturnal staphylinids from Sierra de Huautla, Morelos, Mexico is presented. The fieldwork was carried out between November 1995 and October 1996, with monthly light trap samplings used as collection method. A total of 14 886 individuals were collected, belonging to 91 species, 49 genera, 15 tribes and 9 subfamilies. The subfamilies with the greatest number of individuals and species were Paederinae, Aleocharinae and Oxytelinae. The distribution of individuals per species was heterogeneous, with few species very abundant and many with only a few individuals. There were seasonal differences in richness and abundance and the highest number of species and individuals were recorded during the rainy season. The abundance and richness were related with precipitation, but not with temperature.
