Revision of Limnocoris Stål (Heteroptera: Nepomorpha: Naucoridae) of the tropical Andes.

The species of Limnocoris of the tropical Andes of South America are revised, including the descriptions of eight new species: L. chrysosetosus n. sp. from Ecuador; L. elongatus n. sp. and L. emboliatus n. sp. from Colombia; L. molanoi n. sp. from Colombia and Ecuador; L. luisae n. sp. from Colombia and Venezuela; L. longirostris n. sp. from Venezuela; L. nieseri n. sp. from Colombia, Ecuador, and Panama; and L. reynosoi n. sp. from Brazil, Colombia, and Venezuela. Further, supplemental descriptions are provided for the previously described species. The following taxa are resurrected from synonymy and their species status are restored: Limnocoris peruvianus Melin stat. restit. from synonymy with L. pectoralis Montandon, and L. stali Montandon stat. restit. from synonymy with L. borellii Montandon. The following synonymies are proposed, with junior synonyms in brackets: L. borellii Montandon [L. horvathi Montandon n. syn.], L. dubiosus Montandon [L. aymarana Poisson n. syn.], L. malkini La Rivers [L. pulchellus n. syn.], L. obscurus Montandon [L. trilobatus Nieser, González, Eichelkraut, n. syn.], L. ochraceus Montandon [L. maculatus De Carlo n. syn.], L. pallescens (Stål) [L. bergrothi Montandon n. syn.], L. pectoralis Montandon [L. rivalis Melin n. syn.], L. peruvianus Melin [L. calii Nieser, González Eichelkraut n. syn.] and L. stali Montandon [L. robustus Roback Nieser n. syn., L. carcharus La Rivers n. syn.]. Lectotypes are designated for five species: L. aymarana, L. bergrothi, L. borellii, L. dubiosus, and L. stali. An illustrated taxonomic key and distribution maps also are presented.
