Análisis de la diversidad de Coleoptera en el bosque tropical caducifolio en Acahuizotla, Guerrero, México

A faunistic study of Coleoptera (Insecta) in the tropical dry forest of Acahuizotla, Guerrero, Mexico between February 2008 and October 2009 was done. Using entomological nets and light traps, 4,738 adult specimens were collected belonging to 50 families, 251 genera and 523 morphospecies. 80.5% of the specimens were collected with light traps. Diversity of order 1 (exponential of the Shannon index) reached a value of 153.32 effective species while diversity of order 2 (inverse of the Simpson index) was 68.30 effective species. According to the Chao1 and ACE estimates, the expected richness is 903 and 844 morphospecies, respectively (our sampling representing between 57.9% and 61.9%). The similarity between the sites was higher in those where light traps were used, because these insects were attracted by the artificial light.
