History and Synonymy
1999
Kiel & Bandel, 1999, p. 52:
- "Apart from the type species and the two new species described below, Strombus? dallianus WHITE 1887 from Brazil might belong here."
Kiel & Bandel, 1999, p. 56:
- "Perustrombus is only known from the Maastrichtian where it reached a wide distribution ranging from southern India (P. indicus) along the Tethyan shores to Egypt (P. africanus) to the southeastern Pacific and northern Peru (P. wheeleri OLLSON 1944). It appears to have evolved from the Indian Ocean varieties of Pugnellus by total reduction of the extensions on the outer lip and seems to have preferred the warmer to temperate Tethyal realm."
