Description of a new subgenus and a new species of Thamnocephalus (Crustacea: Branchiopoda, Anostraca) from the Salinas Grandes Basin, Córdoba Province, Argentina

At present, the American genus Thamnocephalus has three species, recorded from several states of U.S.A., México and Venezuela: Thamnocephalus platyurus Packard, T. mexicanus Linder and T. venezuelensis Belk & Pereira. The new species Thamnocephalus salinarum, from a turbid saline temporary pond...

The new species Thamnocephalus salinarum, from a turbid saline temporary pond inside the Salinas Grandes of Córdoba, Argentina is described here. The new species differs from all other congeners by the presence in the male, of an unbranched frontal appendage and a pair of soft cordiform parapenial lobes; also, by the sexually dimorphic caudal fin-like lobe. This new species may represent a new genus, however since only five specimens were collected it was not possible to observe if the penial ornamentation conforms to the Thamnocephalus type. Therefore, a conservative position is taken until new material allows proper analysis, by keeping the new species in the genus Thamnocephalus under the new subgenus Simplicephalus. 2002 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00188158_v486_n_p91_Cohen http://hdl.handle.net/20.500.12110/paper_00188158_v486_n_p91_Cohen
