| Summary: | Progonus muelleri (Levinsen, 1881) and Derogenes varicus sensu lato The monotypic genus Progonus was erected by Looss [38] for P. muelleri, first described from waters off Greenland [35]. The two genera Derogenes and Progonus are very similar with the only difference being the presence of a cyclocoel in P. muelleri vs. blindly ending caeca in species of Derogenes [19, 35, 49]. We examined body sections of representatives of both genera, mainly D. varicus s. s. from Limanda limanda (Fig. 5C) and P. muelleri from M. scorpius and the two species can also be readily distinguished by the seminal vesicle, located in the anterior third of the midbody of D. varicus s. s. vs. in the posterior third of the midbody in P. muelleri. Additionally, the pars prostatica is far shorter in P. muelleri (see Fig. 5). We examined additional specimens of Derogenes spp. from T. Odhner’ s collections at the Invertebrates collection in the SMNH (Figs. 9 and 10), all identified and labelled as D. varicus, which we consider herein as ... : Published as part of Bouguerche, Chahinez, Huston, Daniel C., Karlsbakk, Egil, Ahmed, Mohammed & Holovachov, Oleksandr, 2024, Untangling the Derogenes varicus species complex in Scandinavian waters and the Arctic: description of Derogenes abba n. sp.
