Notes on the morphology of two species of Limnocoris St?l (Heteroptera: Naucoridae) from South America

In the present study, new distribution records and notes on the wing polymorphism of Limnocoris pallescens (Stal, 1861), a species distributed in Colombia and Venezuela, are presented. Also, after the discovery of two female paralectotypes of L. pectoralis Montandon, 1897 deposited at the Natural History Museum in London, ongoing uncertainty about the shape of the diagnostic mediosternite VII (subgenital plate) of this species has been resolved.
