Typophyllum inflatum Vignon 1925

T. gibbosum Vignon 1925 syn. nov.

http://lsid.speciesfile.org/urn:lsid: Orthoptera .speciesfile.org:TaxonName:5502 T. inflatum: Vignon 1925b: 446 , Vignon 1931: 129, Beier 1960: 362; T. gibbosum: Vignon 1925b: 448 , Vignon 1931: 130, Beier 1960: 262.

First group according to Vignon (1925a). T. inflatum is described from a female holotype, along with a male holotype as variation minor, that subsequently became syntype or allotype of inflatum ( Vignon 1931) . T. gibbosum is known from a unique female. All three specimens (photos in OSF) are from Chiquitos in eastern Bolivia (Departamento Santa Cruz). The only difference between the female types is the dimension of the postmedian dilatation of the costal margin of the tegmina. In gibbosum it is more pronounced. However, the degree to which the costal margin is dilated is variable, as shown by 12 female specimens from Iguazú National Park in northeast Argentina, where T. inflatum has recently been found (Braun in prep.). T. abruptum Brunner von Wattenwyl 1895, described from a slightly smaller female from Bolivia, is also very similar (photos in OSF). It has tegmina with a distally undulated anal margin, a condition not found among the Iguazú specimens. So it seems advisable to wait with a possible synonymization until more specimens from Bolivia become available.
