Etymology: Peckoltia: Because of Gustavo Peckolt,member of the Natural History Commission of Rondon (Ref. 45335); cavatica: Derived from Latin cavaticus meaning born or living in caves, in reference to the fact that most of the specimens were captured from holes in lateritic rocks and the fact that is likely that such holes are where this species breeds.
Eponymy: Gustavo Peckolt (1861–1923) was a Brazilian-born German botanist and pharmacist. [...] (Ref. 128868), visit book page.
