A new species of Martarega white, 1879 from South America (Hemiptera: Heteroptera: Notonectidae), with an identification key to all described species of the genus

Martarega guarani sp. n. is described and illustrated from north-eastern Argentina (Misiones Province), based on brachypterous forms of both sexes and macropterous females. Comparisons with its close relative M. uruguayensis are included. The hind femur with a basal notch extending some distance bey...
