Type material. Holotype male from BRAZIL, São Paulo: Ilha da Vitória, 16-27.III.1964, Expediç „o Departamento de Zoologia leg. ( MZSP 52546 ).

Etymology. The epithet is a reference to the Brazilian state of S„o Paulo, where the holotype was collected.

Remarks. Pseudosparna paulista sp. nov. is similar to P. boliviana Monné & Monné, 2011 (see photographs in original description and on Bezark 2023), but differs as follows: elytral apex obliquely truncate, with sutural angle not projected; the longitudinal light band on the elytra is sinuous, narrowed on its anterior third, and inclined toward epipleural margin on its posterior region, not reaching elytral apex. In P. boliviana , the elytral apex is concave centrally, making the sutural angle projected, and the light band on the elytra is straight and reaches the elytral apex. The new species differs from P. luteolineata Mermudes & Monné, 2009 (see photographs in original description and on Bezark 2023) by the dark pubescent area on the pronotum distinctly wider, about 0.7 times width of anterior margin of the prothorax (narrower, at most half of width of anterior margin of the prothorax in P. luteolineata ), and the light pubescent band sinuous and projected toward epipleural margin on its posterior region (straight and only dorsal posteriorly in P. luteolineata ).

According to Barbo et al. (2012), who described a new species of Bothrops Wagler, 1824 ( Reptilia, Viperidae , Crotalinae ) from Vitória island: “The new species is known only from the type locality, Vitoria Island (23º44’44” to 23º45’00”S and 45º01’01” to 45º00’27”W), Ilhabela Archipelago, Brazil. In this archipelago, Vitória is the easternmost island, located ca. 23 km east of S„o Sebasti„o Island, and ca. 30 km southeast of Ubatuba, northern coast of S„o Paulo, southeastern Brazil. Vitoria Island has about 220 ha, with a maximum elevation of ca. 200 m above sea level and with the predominant vegetation being Atlantic forest.”
