Two Cipangopaludina snails were discovered in Harris County, Texas, USA, during routine fieldwork in October 2015. Dissection yielded one male and one female containing 52 offspring in her brood pouch. Phylogenetic analysis of the cytochrome c oxidase subunit I (COI) gene confirmed both individuals to be Cipangopaludina japonica (von Martens, 1861). This is the first distribution record of C. japonica in Texas. Non-native invasive snails, such as C. japonica, compete with native species and may serve as reservoirs for parasites, prompting the need for increased diligence in monitoring public waterways.
