Etymology. The specific epithet refers to the Granma province; on its coasts the expedition of the "Granma Yacht" landed, bringing Fidel Castro and his guerrillas from Mexico. It also refers the National Park “Desembarco del Granma ”, one of the most highly protected preservation areas in Cuba where the species is distributed.

Diagnosis. Males of T. granmense sp. nov. resemble those of T. soroense sp. nov.; T. cubanum and T. cheguevarai sp. nov., by their rounded tegulum ( Fig. 14E–G) but differ by the STC with double row of teeth. They also differ from T. cheguevarai sp. nov. by the embolus without keels and from T. soroense sp. nov. by the long and procurved embolus in ventral view. It differs from T. baracoense sp. nov.; T. rudloffi sp. nov. by the rounded tegulum. Females can be distinguished from all other species by the shape of the spermathecae ( Fig. 15F). It resembles those of T. citma sp. nov.; but differs by the subequal spermathecal lobes.
