New records of Odonata from central and Pacific Mexico

Abstract

In this paper, we provide updates on Odonata collected in Mexico. During the last several years, a number of Odonata have been collected from the central and Pacifi c regions of Mexico that represent new state records. Additionally, we provide locality data for species collected from South Coronado Island from Baja California state. While these species have been recorded for the state, they have not been recorded for the Island. Many of these species have also been reported for the nearby states of California, U.S.A. and Baja California Sur, Mexico (Needham et al. 2000, Manolis 2003, Paulson & González-Soriano 2020). Paulson & González-Soriano (2020) reported 365 species of Odonata in Mexico. Our knowledge about the geographic distributions of some Odonata species of Mexico has been advancing during the last 40 years with the identifi cation of species with wide geographical ranges and some with more limited geographical distributions (González-Soriano & Novelo-Gutiérrez 2014). However, in some species, aspects such as altitudinal distribution, biogeographic affi nities, seasonal occurrence, and distribution with precise localities data are still unknown (Escoto-Moreno et al. 2020). In Mexico, there are still a number of states for which our knowledge of Odonata is poor. A clear example is Zacatecas state, which only has one study that includes southwestern locations (Escoto-Moreno et al. 2015). The islands of Mexico and the Pacifi c, many of which are small but located near the mainland, have not had formal studies of Odonata, and it is necessary to carry out explorations in those areas because some species migrate across the ocean and inhabit these islands (Behrstock 2008, Bérmudez & López-Victoria 2009, Paulson 2019). The information presented here supplements the survey of species of Odonata from Mexico made available online (Paulson & González-Soriano 2020). First records for the states of Aguascalientes, Colima, Zacatecas and the South Coronado Island of Baja California, are the result of occasional collecting by the authors, colleagues, and students who deposited material in the Zoological Collection of the Universidad Autónoma de Aguascalientes (CZ-UAA). Classifi cation follows Dijkstra et al. (2013), and maps are included to graphically illustrate these new records.
