Entiminae diversity (Curculionidae: Coleoptera) from three localities in the Sierra de Morelos Huautlla

The Entiminae subfamily (Curculionidae: Coleoptera) has a globally diverse species of 12,200, only 372 of which have been reported for Mexico. Morelos State does not have records on this taxon, despite having a prime location between the Transverse Volcanic Belt and Balsas Basin. In the Balsas Basin in Morelos, the dry forest is preserved in the Sierra de Huautla, This vegetation type is considered the richest and most endemic of all plant communities. The purpose of this work is therefore to generate an inventory of species and to analyze the diversity of the Entiminae subfamily in Sierra de Huautla, Morelos, Mexico. Sampling was conducted monthly for a year in three locations: San Miguel de los Elotes and Huautla - Ajuchitlan, both belonging to the municipality of Tlaquiltenango and El Limón de Cuauchichinola, in the municipality of Tepalcingo. Collections were taken one day a month in each locality, for seven hours. In each sample a walk along transects of variable length was conducted. The entomological material was collected by beating umbrella. A total of 378 individuals from the three locations were recorded, of which 75 were collected in San Miguel de los Elotes, 167 in Huautla - Ajuchitlan and 136 in El Limón de Cuauchichinola. Five tribes (Eudiagogini, Naupactini, Ophryastini, Polydrusini and Tanymesini), in seven genera (Eucoleocerus, Coleocerus, Ophryastes, Megalostylus, Pandeleteius, Naupactus and Polydrusus), and 17 species (Pandeleteius sp. 1, P. sp. 2, Ophryastes sp. 1, O. sp. 2, O. sp. 3, Naupactus aff. stupidus, Megalostylus albicans, M. sp. 1, M. splendidus, Polydrosus sp. 1, P. sp. 2, P. macrocephalus, P. pallidisetis, Coleocerus setosus, C. variegatus, C. sp. 1 and Eucoleocerus sp. 1) were recorded, as preliminary results. For the diversity analysis in this paper, the authors used the concept of true diversities according to Jost (2006), whose unit of measurement is the effective number of species. In other words, it measures the diversity a community comprising equally common species would have. The results of the true alpha diversity of order 1(1Dα), were 6.62 for San Miguel Elotes, 1.76 for Huautla - Ajuchitlan and 5.17 for El Limón de Cuauchichinola. For beta diversity (replacement rate) the three communities were compared in paired and the following results were obtained: for San Miguel de los Elotes vs Huautla-Ajuchitlan 1.68; Huautla-Ajuchitlan vs El Limon de Cuauchichinola 1.58 and El Limon de Cuauchichinola vs San Miguel de los Elotes 1.39. The richest place was San Miguel de los Elotes while the greatest abundance was recorded in Huautla - Ajuchitlan.
