Revision of the American genus Steinovelia Polhemus amp; Polhemus, 1993 (Heteroptera: Gerromorpha: Veliidae).

ABSTRACT

The genus Steinovelia Polhemus Polhemus, 1993 is distributed from southeastern Canada to northeastern Argentina and has been considered to contain five valid species S. permista (Drake, 1951a), S. placida (Drake, 1951a), S. stagnalis (Burmeister, 1835), S. vinnula (Drake, 1951b) and S. virgata (White, 1879a). We present here a revision of the genus with redescriptions of S. permista, S. stagnalis, S. vinnula, and S. virgata, the synonymy of S. placida with S. virgata, a key, distribution maps, and photographs of all species.
