The Eastern Asian ectoparasitic copepod Neoergasilus japonicus (Harada, 1930) is a widely spread species with a high prevalence on many freshwater teleosts. It was recorded for the first time in Europe 45 years ago and continued its invasion to new geographic regions. Its presence in North America was first detected in 1993, followed by only two other continental records. In this work we present an illustrated record of N. japonicus from plankton samples collected during 1990 in a microreservoir of central Mexico. We confirm that this parasitic copepod was already present in continental America at least 3 years before previously known. This is the third published record of this Asian copepod in the Neotropical region. Its occurrence in Mexico is attributed to different events of introduction by human agency. This report supports the notion that N. japonicus is more widespread in Middle America than previously thought and it is intended to aid in the historical monitoring of the invasion of this species.
