This research records the species of semi-aquatic bugs (Hemiptera: Gerromorpha) from the coastal strip of the Utría National Natural Park (Chocó, Colombia). During a field trip in February 2019, individuals were collected in different habitat types: cove, mangrove, beach and stream. In each habitat, collections were made using aquatic entomological nets, with a sampling effort of two hours/man. A total of 192 individuals were collected, where 93% were determined to species and 7% to genus. Thus, 11 species and two morphospecies were recorded, four species for the Gerridae family and seven for the Veliidae family. The morphospecies belong to the genera Rhagovelia and Microvelia (Veliidae). Four species endemic to the biogeographic Chocó that have been recently described are highlighted: Rhagovelia molanoi, Rhagovelia nuqui, Rhagovelia utria and Stridulivelia chocoana. The results of this project were within the framework of the taxonomic revision of the family Hydrometridae for Colombia.
