Just, Jean & Wilson, George D. F., 2007, Revision of Austrosignum Hodgson and Munnogonium George & Strömberg (Paramunnidae) with descriptions of eight new genera and two new species, (Crustacea: Isopoda: Asellota), Zootaxa 1515, pp. 1-29 : 22

Quetzogonium gen. nov.

Type species. Austrosignum dentatum Winkler, 1994 . — Here designated.

Species included. Quetzogonium dentatum ( Winkler, 1994) , comb. nov.

Diagnosis. Body ovate. Head front margin concave in middle. Pereonites dorsally smooth. Pleotelson lateral margins with a few denticles level with uropods. Eyestalks robust, rounded, pointing laterad, approximately as long as wide. Antennula article 1 shorter than eyestalk. Antenna article 3 with spines on lateral margin. Mandible palp present. Pereopod I carpus triangular, with 2 straight robust setae posteriorly; propodus with 2 robust setae on posterior margin. Pereopod II carpus and propodus posterior margin with a few short robust setae. Uropod endopod straight, apex truncate.

Etymology. The genus name is comprised of an arbitrary combination of letters and the traditional paramunnid ending – gonium.

Remarks. We have not seen Winkler’s (1994) material. Our analysis of the species is based on description and illustrations in Winkler (1994: 284, figs 34–37).

Quetzogonium differs from the other genera treated here by the combination of a concave front margin of the head, the presence of a mandibular palp, and denticulate margins of the pleotelson.

Distribution. Magellan Strait, Chile. 12– 40 m.
