Abstract

In some prospections carried out in 2022 in the “saladars” areas of the Plana de Lleida to determine the distribution of the saltmarsh band-winged grasshopper (Mioscirtus wagneri) we discovered Heteracris adspersa for the first time in Catalonia. We present new data on the habitat where this species was found, which is mainly located on Suaeda vera. This plant provides food and shelter for this grasshopper. A key is provided to differentiate the two species of the genus Heteracris present in Catalonia: mediterranean splendid grasshopper (H. littoralis) and splendid grasshopper (H. adspersa). Llagost de ponent” is proposed as a catalan common name for the second species. For its very restricted distribution, this species is proposed to be included in the Endangered Fauna Catalog of Catalonia.
