The larval stages of Andogyrus seriatopunctatus Régimbart are described and illustrated, including morphometric andchaetotaxic characters. A larval ground pattern for the chaetotaxic characters is presented; it is based on first instar larvaeof A. seriatopunctatus. Unidentified larvae of Dineutus MacLeay and a third instar larva of Gyrinus argentinus Steinheilwere also inspected. For chaetotaxic homologization comparisons with other adephagan families were performed,mainly with Carabidae and Dytiscidae. The ground pattern is considered provisional due to the lack of previous studiesin this family. Larvae of A. seriatopunctatus are briefly compared to those of A. buqueti (Aubé). Notes on the biology ofA. seriatopunctatus are also included.
