This species was originally described based on a single specimen from Veracruz, Mexico (see photograph of the holotype at Bezark 2019a). Breuning (1949) synonymized Paratucumaniella with Cacostola , and P. mexicana with Cacostola simplex . Marinoni and Martins (1982), revalidated the species (translated): “ C. mexicana Breuning is equally distinct from C. volvula by having the light pubescence of the distal half of the elytra forming irregular bands, but distinct, strongly contrasting with the dark pubescence around it.” The authors compared Paratucumaniella mexicana with Cacostola volvula , because in the same work they revalidated C. simplex . Breuning (1959) had synonymized C. simplex with C. volvula and, accordingly, P. mexicana with C. volvula , too.

We know that Marinoni and Martins (1982) based this decision on a photograph taken by Jesus Santiago Moure in the 1970s at USNM ( Fig. 43 ). Apparently, the specimen photographed has a “cotypus” label. However, since the species was described based on a single specimen: “Länge 13 mm, Breite 3 mm. Typ von Mexico: Jalapa in Museum von Hamburg” it cannot be a type (although it does appear to be a specimen of C. mexicana ).

According to Monné (2018) the species remains known only from Mexico.
