38 Bulletin of Zoological Nomenclature 60( 1 ) March 2003 Case 3225 Phymaturus Gravenhorst, 1837 and Lacerta palluma Molina, 1782 (currently Phymaturus palluma; Reptilia, Sauria): proposed conservation of usage of the names by designation of a neotype for Lacerta palluma Molina, 1782 Richard Etheridge and Jay M. Savage Department of Biology, Son Diego State University. San Diego. California, 92182-4614 U.S.A. (e-mail: [email protected]) Abstract. The purpose of this appHcation, under Article 75.6 of the Code, is to conserve the widespread existing usage of the generic name Phymaturus Gravenhorst, 1837 and the specific name P. palluma (Molina, 1782) for a genus and a species of lizard (family liolaemidae) from South America by designating the holotype of Cemrura flagellifer Bell, 1843 as the neotype of Lacerta palluma Molina, 1782. Phymaturus and P. palluma have been used in this sense since the name L. palluma was first misapplied by Gravenhorst in 1837. In this application it is accepted that the valid name for Molina's lizard species will be Callopistes maculatus Gravenhorst, 1837. Keywords. Nomenclature; taxonomy; Reptilia; liolaemidae; teiidae; Callopistes: Phymaturus; Callopistes maculatus; Phymaturus palluma; lizard; South America. 1. Molina (1782, p. 217) described a species of lizard (family teiidae) from Chile and named it Lucerta palluma after an Araucanian Indian name; palluma is a noun in apposition. In the same work (1782, p. 345) and in its second edition (Molina, 1810, p. 189), Molina then used a different spelling for the generic name, referring to the taxon as Lacerta palluma. In so doing he acted as the First Reviser and selected Lacerta palluma as the valid spelling (see Article 24 of the Code). 2. Gravenhorst (1837, p. 749, pi. 55, fig. 2) placed what he thought was the nominal species Lacerta palluma Molina, 1782 in a new genus which he named (p. 749) Phymaturus. Lacerta palluma Molina, 1782 is thus the name of the type species by monotypy of Phymaturus. He illustrated a dorsal view of the lizard's head, but had misidentified Molina's taxon. Gravenhorst's lizard belongs to the family LIOLAEMIDAE, whcrcas Molina's lizard belongs to the family teiidae. Molina's specific name palluma has been mistakenly applied to Gravenhorst's taxon for over 100 years. 3. Bell (1843, p. 25, pi. 14, fig. 2) described a new genus and species of lizard with the name Centrura flagellifer (family liolaemidae). His illustration of the holotype (which is held in The Natural History Museum, London, with accession number BMNH 1922.214.171.124 and examined by R.E. in 1968) is clearly that of the species referred to as Phymaturus palluma by Gravenhorst (1837). Boulenger (1885, p. 184) synonymized Cemrura flagellifer with Phymaturus palluma sensu Gravenhorst, 1837.
