Abstract
Introduction: The Cyprinodontiformes are a group of secondary freshwater fishes widely distributed in El Salvador. Currently, many species of this group are usually incorrectly identified for lack of adequate tools. Additionally, their taxonomy and distribution have changed in recent years. Objective: To provide updated information about the taxonomy and distribution of El Salvador Cyprinodontiformes through identification keys, distribution notes, and general descriptions for all species. Methods: We carried out an extensive review of the literature, electronic databases, and museum specimens to generate a list of valid species present in El Salvador. Results: Eleven species in three families are confirmed: Profundulidae (two species), Anablepidae (one species), and Poeciliidae (eight species). We also include distribution data, both vertical and by main basins, and an illustrated guide. Conclusions: There are 11 species of Cyprinodontiformes in El Salvador and they can be found and identified with this article.

Records of cyprinodontiform fishes present in El Salvador were obtained from the scientific literature (Alda et al, 2013; Salgado-Maldonado et al, 2014), voucher specimens at the Museo de Historia Natural de El Salvador (MUHNES), the Instituto de Ciencias del Mar y Limnología, Universidad de El Salvador (ICMARES-UES), Museo Nacional de Ciencias Naturales, Madrid, Consejo Superior de Investigaciones Científicas (MNCN-CSIC) and electronic databases of the United States National Museum (USNM), University of Kansas (KU), Field Museum of Natural History (FMNH), Swedish Museum of Natural History (NRM), California Academy of Sciences (CAS), Tulane University (TU), Louisiana Museum of Natural Science (LSUMZ), and University of Michigan Ann Arbor (UMMZ) accessed via FishNet2
Within the family Poeciliidae, Poecilia gillii and P. butleri, as reported by McMahan et al (2013), were excluded from this revision since recent molecular evidence suggests that these species do not occur in El Salvador (Alda et al, 2013; Ho et al, 2016; Palacios et al, 2016)
Summary
Miller, 1966; Myers, 1966; Rosen, 1975; Briggs, 1984; Bussing, 1985; Iturralde-Vinent & MacPhee, 1999; Iturralde-Vinent, 2006; Hrbek, Seckinger, & Meyer, 2007; Alda, Reina, Doadrio, & Bermingham, 2013; Bagley et al, 2015; Ho, Pruett, & Lin, 2016; Palacios, Voelker, Rodriguez, Mateos, & Tobler, 2016; Amorim & Costa, 2018) In this regard, the evidence provided by several authors (Myers, 1966; Rosen, 1975; Iturralde-Vinent & MacPhee, 1999; Hrbek et al, 2007; Matamoros, McMahan, Chakrabarty, Albert, & Schaefer, 2015) suggests that Cyprinodontiforms arrived to Nuclear Central America possibly in three dispersal events. Our objectives were a) to present updated taxonomic information on cyprinodontiform fishes from El Salvador, including their geographical distribution and habitat use, and b) to provide a photographic taxonomic key to facilitate their identification
