Lutosa brasiliensis ( Brunner von Wattenwyl, 1888)

http://lsid.speciesfile.org/urn:lsid: Orthoptera .speciesfile.org:TaxonName:20080

Comments. This species was originally described as Pherterus brasiliensis Brunner von Wattenwyl, 1888 . Its description was based on a male and a female from Theresopolis, Santa Catharina, Brazil. This locality was a colony of German immigrants located at the banks of Cubatão River (and not the city of Teresópolis, Rio de Janeiro), near the capital of the state, Florianópolis. Currently, this locality is a district of the municipality of Águas Mornas ( Map 1 ). Unfortunately, the two specimens used for the original description are lost (H. Braun comm. pers.), three specimens deposited in Vienna, identified as L. brasiliensis (two females and one male) do not belong to the specimens originally studied by Brunner von Wattenwyl (1888), they were actually later determined by Karny (1930).

The brief original description indicates that the fore tibia has two spines on the outer dorsal margin and the hind tibia is curved. Specimens currently identified as L. brasiliensis in Vienna do not meet these characteristics, and for us is a misidentification. With this scenario, the type specimens are lost and providing a redescription and reliable identification is not possible at this time. Therefore, it is necessary to designate a neotype, preferably from the type locality and that fits the morphological characteristics originally described, it is not recommended to make specimens from other localities, even if the localities are close, since this is a specious genus (although many of its species are still not formally described).
