Status Thelepus crassibranchiatus was synonymized by Hartman (1959) with Thelepus cincinnatus. Holthe (1986b) followed this. Nevertheless, after the revision of material of T. cincinnatus from Sweden (USNM 79669 (5) North Atlantic Ocean, Sweden, Loken, Skagerrak, 14.VI.1967; 37m. USNM 79670 (7) North Atlantic Ocean, Sweden, Smörkullen, Gullmar Fjord, 15.VI.1967; 40m), near the type locality (Greenland), there are important differences, which justify considering T. crassibranchiatus as a valid species [details]
