In addition, previously published rpb2 sequences were used to provide the phylogenetic position of species in subgenus Telamonia. Based on these results the new section Disjungendi, subgenus Telamonia is proposed. Six species belong to this section: C. claroplaniusculus, C. disjungendus, C. disjungendulus, C. olididisjungendus, C. orasericeus, and C. piceidisjungendus. Of these, C. disjungendus, C. disjungendulus, and C. claroplaniusculus are to date only known from Europe whereas the others occur both in North America and Europe. Based on ITS sequences, three of the six species had taxonomic synonyms: C. claroplaniusculus (synonym C. hymenoluctus and C. planodepressus), C. disjungendus (synonyms C. remauxii, C. conicosordescens, and C. solivagus), and C. orasericeus (synonym C. brunneofulvus f. myrtillophilus). This study demonstrates how difficult it can be to identify species only on the basis of morphology and emphasizes the importance of molecular studies of type and other specimens particularly in groups with cryptic taxa.} }
