Paraterpnistria Piza, 1980 syn. nov. of Callinsara Rehn, 1913

As the genus name indicates, Piza compared his male specimen from northeastern Brazil only to the African genus Terpnistria , whose type species T. zebrata actually looks a little bit similar. The specimen also resembles the female type of Sictuna strigata Walker, 1896 from Venezuela (two small photos of dorsal views in OSF), which has similarly coloured and shaped tegmina, and very similar dark fringes at the rear margin of the pronotal metazona. But the metazona is much broader in Piza’s specimen, and its fastigium is more acuminate. According to Bruner’s (1916) key in Sictuna the auditory openings in the foretibia are linear, while they are fairly broad and oval in Piza’s specimen. This specimen is also quite similar to the male holotype of Callinsara clupeipennis Rehn, 1913 from northeastern Argentina (the type species of that genus, that includes a second species from Bolivia), which also has translucent fringes along the transversal veins of the tegmina. Also the shapes of pronotum and stridulatory area are fairly similar. Since Piza’s specimen fits very well into Rehn’s (1913) diagnosis of Callinsara , we move it there. However, upon closer examination of specimens it might turn out that Callinsara is in fact identical with the monospecific genus Sictuna .
