Four new species of Ischnodemus (Hemiptera, Heteroptera, Blissidae) and additional records from Argentina

Abstract

Four new species of the genus Ischnodemus Fieber, 1837 (Hemiptera, Heteroptera, Blissidae) are described from Argentina: I. nigromaculatoides sp. nov., I. formosus sp. nov., I. infernalis sp. nov. and I. correntinus sp. nov. The known distribution is extended for three previously recorded species in the country. The species Ischnodemus brusai Dellapé & Montemayor, 2009 from Peru is transferred to Patritiodemus Slater & Ahmad, 1971. Dorsal habitus photographs and detailed images of the pygophore and right paramere of the new species and a key to the Argentinean species of Ischnodemus are given.
