ABSTRACT. The genus Chaetocladius (Chaetocladius), laminatus-group (male adults and pupal exuviae) is reviewed and diagnosed based on material composed of male pharate adults, male adults and pupal exuviae recently collected in some glacial springs and small streams located in both France (Pyrenees) and Slovakia (Tatra mountains). Taxonomic notes provided in this paper include a supplemented diagnosis of the laminatus-gr. based on some relevant characters found in the male adult of some sibling species. Description of C. guisseti sp.n. as male adult and male pupal exuvia, short redescription of C. laminatus Brundin, 1947 and additional short descriptions and illustrations of four undescribed species (C. sp.A, as male adult; C. sp.B, as male adult and pupa; C. sp.1 and C. sp.2 as pupa) are adduced. Remarks, taxonomic position, ecology and geographical distribution of the new described species are given.
KEY WORDS: Diptera, Chironomidae, Chaetocladius genus (laminatus-group), new species, Eastern Pyrenees.
