Abstract

NOGUERA, Felipe A. et al. Cerambycids (Coleoptera: Cerambycidae) from a tropical dry forest in Santiago Dominguillo, Oaxaca, México. Rev. Mex. Biodiv. [online]. 2012, vol.83, n.3, pp.611-622. ISSN 2007-8706.  https://doi.org/10.7550/rmb.25088.

The results of a study of the fauna of cerambycids of the tropical dry forest of Santiago Dominguillo, Oaxaca, México are presented. The study was carried out between November, 1997 and October, 1998. Collections were carried out during 5 days of every month and the collection methods included light trapping, Malaise trapping and direct collecting. A total of 97 species, 64 genera, 32 tribes and 4 subfamilies were recorded. The subfamily with the greatest number of species was Cerambycinae with 59, followed by Lamiinae with 36 and Lepturinae y Prioninae with 1 respectively. The tribes with the largest number of genera and species were Elaphidiini with 9 and 17, Acanthocinini with 8 and 12, and Trachyderini with 7 and 9 respectively. The genera with most species were Rhopalophora with 6 y Eburia, Aneflomorpha, Stenosphenus and Estoloides with 4. Richness value using a non-parametric estimator was 134 species. Species abundance pattern show a few very abundant species and many with few individuals. The diversity index was H= 3.59. Species richness and abundance were variable: highest values were recorded in the rainy season and the lowest values in the dry season. The faunal compositions include 46% species endemic to Mexico.

Keywords : richness; abundance; phenology; endemism.
