Abstract
The Andean caddisfly genus, Eosericostoma Schmid, 1955, was previously known from two species endemic to Chile and Argentina. In this study, a new species of Eosericostoma was discovered six decades after the last description of a species in the genus. Eosericostoma opposita Desidério, Sganga & Hamada, sp. nov. is described and illustrated based on a single specimen collected close to the Lake Nahuel Huapi, Río Negro Province, in the Valdivian Forest of Argentine Andes. It can be recognised on a combination of abdominal characters, mainly in the tergum X and the inferior appendage. Additionally, a key to identify males of the three species in the genus is provided. Finally, a brief discussion of the biogeography of Eosericostoma is presented.
期刊介绍：
Austral Entomology is a scientific journal of entomology for the Southern Hemisphere. It publishes Original Articles that are peer-reviewed research papers from the study of the behaviour, biology, biosystematics, conservation biology, ecology, evolution, forensic and medical entomology, molecular biology, public health, urban entomology, physiology and the use and control of insects, arachnids and myriapods. The journal also publishes Reviews on research and theory or commentaries on current areas of research, innovation or rapid development likely to be of broad interest – these may be submitted or invited. Book Reviews will also be considered provided the works are of global significance. Manuscripts from authors in the Northern Hemisphere are encouraged provided that the research has relevance to or broad readership within the Southern Hemisphere. All submissions are peer-reviewed by at least two referees expert in the field of the submitted paper. Special issues are encouraged; please contact the Chief Editor for further information.
