Tettigidea cuspidata, Scudder, 1875

Silva, Daniela Santos Martins, Cadena-Castañeda, Oscar J. & Pereira, Marcelo Ribeiro, 2021, Batrachideinae (Orthoptera: Caelifera: Tetrigidae): an overview of the most diverse tetrigids of the Neotropical region, Zootaxa 4946 (1), pp. 1-84 : 49

Tettigidea cuspidata species group

Diagnosis: Body robust. Facial carinae and frontal costa notoriously thickened, in lateral view moderately prolonged and rounded fastigium. All known species brachypronotal. Spine of anterior edge of pronotum sharp, prominent and projecting moderately overhead. Posterior edge of pronotum not surpassing the apex of the abdomen. Median carina of the pronotal disc slightly elevated. Hind wings undeveloped.

Species included: T. cuspidata Scudder, 1875 ; T. glabrata Bruner, 1920 ; T. angustihumeralis Podgornaya, 1999 , and T. parradae Cadena-Castañeda & Cardona, 2015 .

Distribution: South America: Andean foothills of Colombia, Peru (Upper Amazon, without exact location), Brazil, Paraguay, and Andes of Argentina and Bolivia ( Fig. 39 ).

Comments: The male of T. parradae has the terminalia globose and conspicuous, since the males of the other species are known and if they have similar terminalia, this could be a diagnostic character, since this characteristic is not present in the males of the other known species. Then as indicated by Grant (1962), T. corrugata and T. multicostata shared morphological similarities that justify the formation of synonyms. On the other hand, when comparing with type specimens, it was found that both species are also synonymous with T. cuspidata , a name that prevails as it is the oldest. Thus, new synonymy is established here: Tettigidea cuspidata Scudder, 1875 = Tettigidea corrugata Bruner, 1910 syn. nov.; Tettigidea cuspidata Scudder, 1875 = Tettigidea multicostata Bolívar, 1887 syn. nov.

According to the original description of T. angustihumeralis , the author mentioned that the hind wings were developed, but when observing the type specimens, only the tegmina had fully developed, but the hind wings are not visible. Thus, adjusting to the diagnosis of this group of species and the correction of what is mentioned in the original description by Podgornaya (1999) was made.
