Etymology: Pseudolithoxus: Greek, pseudes = false + Greek, lithos = stone + Greek, oxys = sharp; kelsorum: Named in honor of George and Carolyn Kelso whose generous contribution to Texas A&M University
and to the Winemiller Aquatic Ecology Lab has facilitated important ichthyological discoveries, including this new species (Ref. 87302).
Eponymy: Dr George Leslie Kelso (1929–2015) and Carolyn Kelso née Wierichs (1934–2008). [...] (Ref. 128868), visit book page.
