Munnogonium George & Strömberg Munnogonium George & Strömberg, 1968: 15. Type species. Munnogonium waldronense George & Strömberg, 1968. — Original designation. Species included. Munnogonium erratum (Schultz, 1964), M . falklandicum (Nordenstam, 1933), comb. nov., M . globifrons (Menzies, 1962), M. tillerae (Menzies & Barnard, 1959), M . waldronense George & Strömberg, 1968. Diagnosis . Body ovate. Head front margin not projecting. Pereonites dorsally smooth. Pleotelson lateral margins smooth. Eyestalks vestigial, not longer than wide, downward pointed. Antennula article 1 at least twice length of eyestalk. Mandible palp absent. Pereopod I carpus triangular, with 3 straight, subequal robust setae on posterior margin; propodus with simple setae only on posterior margin. Pereopod II carpus and propodus posterior margin with several long, very slender robust setae on posterior margin. Uropod endopod straight, apex truncate. Remarks . The type material of Munnogonium waldronense was not examined and we have not had access to topotypic material. We have, however, examined the type material of M. globifrons and Austrosignum falklandicum (here transferred to Munnogonium ), and topotypic material of M. tillerae . The diagnosis of Munnogonium presented above is based on George & Strömberg’s (1968) description and illustrations. The diagnosis fits the other species here referred to Munnogonium . We do not follow Bowman & Schultz (1974) in synonymising Munnogonium waldronense under the name M. tillerae . George & Strömberg’s description and illustrations of M. waldronense from the San Juan Archipelago, Washington, (1968, figs 1–2) differ from the holotype of M. tillerae from southern California illustrated by Menzies & Barnard (1959, fig 1) and paratypes illustrated by Bowman & Schultz (1974: figs 21–31) in the shape of the front margin of the head (straight to slightly concave in M. waldronense , broadly convex in M. tillerae ) and in M. waldronense having an elongate proximal neck on the male pleotelson, which is not found in M. tillerae. We have confirmed this on topotypic material of M. tillerae . : Published as part of Just, Jean & Wilson, George D.
