  The almost unknown scorpion fauna (Arachnida: Scorpiones) of El Salvador, Central America Abstract (EN) The scorpions from Republic of El Salvador, Central America, have been poorly studied. The present work confirms the presence of at least six species in this country: Didymocentrus krausi Francke, 1978 (Diplocentridae), and five species belonging to the genus Centruroides Marx, 1899 (Buthidae), including the first records for Centruroides koesteri Kraepelin, 1911, Centruroides tapachulaensis Hoffmann, 1932, and an unidentified species of the thorellii species-group. Centruroides tapachulaensis had been confused with Centruroides edwardsii (Gervais, 1843), Centruroides gracilis (Latreille, 1804) and Centruroides margaritatus (Gervais, 1841). None of five nominal identified species are Salvadoran endemism. A taxonomical key is included for the identification of these six scorpion species. Most of the new records were made based on available data on the iNaturalist citizen science...

Human activity facilitates the dispersal of spiders beyond their native ranges, often allowing populations to establish in synanthropic environments. Synanthropic spiders provide well-documented cases of arthropods adapting to human-modified habitats, with examples across multiple families (e.g. Dippenaar-Schoeman et al. 2023, Henrard 2023, Murcia-Moreno & Gálvez 2024), including corinnids such as Meriola arcifera (Simon, 1886), M. cetiformis (Strand, 1908) and Falconina gracilis (Keyserling, 1891), all confirmed as synanthropic and introduced species (Taucare-Ríos et al. 2013, Nieto-Ruiz & Maldonado-Carrizales 2024).
