Abstract

FERNANDEZ-AZUARA, Geovany De Jesús et al. Diversity of Tettigoniidae (Orthoptera: Ensifera) in the Huasteca Region, Hidalgo, Mexico. Acta Zool. Mex [online]. 2018, vol.34, e3412136.  Epub Nov 16, 2018. ISSN 2448-8445.  https://doi.org/10.21829/azm.2018.3412136.

Four subfamilies, 17 genera and 22 species of Tettigoniidae are reported; of these, 11 are new records for the state of Hidalgo. The Shannon index showed that the study area presents a high and uniform diversity: Oak Forest (BE) H'= 2.78, Rain Forest (SM) H'= 2.23 and Mountain Cloud Forest (BMM) H'= 2.13. The subfamily Phaneropterinae showed the highest abundance (N) with 103 individuals, representing 53% of the total collected specimens (195). This subfamily also showed the highest richness (S) with 67% (14 taxa) of the total species (22) collected. The Sorensen index, modified by Bray Curtis showed that similarity in the faunal composition between the ecosystems is as follows: BE-SM (0.36), SM-BMM (0.49) and BMM-BE (0.33). The Morisita-Horn Index resulted in a similarity of 77% between BE-SM, 62% between SM-BMM and 76% between BE-BMM. Both, N and S showed a negative relationship in reference to the elevational gradient, which occurs in other insect groups.

Keywords : Katydids; abundance; species richness; elevational gradient.
