Abstract
This paper presents a description of the hitherto unknown larva of Schizopelex huettingeri Malicky 1974 (Trichoptera: Sericostomatidae). We provide information on the morphology of the larva and figure the most important diagnostic features. Schizopelex huettingeri can be easily separated from Oecismus monedula (Hagen 1859), Sericostoma flavicorne Schneider 1845, and Sericostoma personatum (Kirby & Spence 1826) by the shape of the pronotum, the lack of a comma-like marking on the lateral protuberance, and by the number of setae on abdominal dorsum IX. With respect to distribution, S. huettingeri is an endemic of European Ecoregion 6 (= Hellenic western Balkan region), inhabiting the mountains of Central Greece. Ecological characteristics of the species are briefly discussed, and a preliminary key to the hitherto known Sericostomatidae larvae of European Ecoregion 6 is included.
