enry Weed Fowler was an eminent Ichthyologist who
was one of the founder members of the American Society
of Ichthyologists and Herpetologists and later briefly
served as the society's president (1927-1928). He
traveled to the interior of Bolivia, alongside collogues
in 1936-1937. As an aside, William C. Morrow took
an expedition of his own to the Ucayali River basin
of Peru in 1937 and collected this species which he
deposited in the Academy of Natural Sciences of Philadelphia.
Fowler wrote an article named "A Collection of
Fishes obtained by William C Morrow in the Ucayali
River basin in Peru" and named three species
of Rineloricaria, one to Morrow and the other
two who accompanied him on the trip, Thomas W. Wolfe
(Rineloricaria wolfei), and Robert T. Petley
(Rineloricaria petleyi) which was removed
from synonymy with Limatulichthys griseus
by Isbrücker in 2001 and is now Limatulichthys
petleyi (Fowler, 1940).

The Rineloricaria genus is part of a group
alongside the Dasyloricaria genera known
as the Rineloricaria group. The Dasyloricaria
genera have sexual dimorphism similar to that of Rineloricaria,
including hypertrophied odontodes forming brushes
on the lateral surfaces of the head in mature males.
The Rineloricaria genus, is by far the most
speciose in Loricariinae, and is widely distributed
on nearly the entire subcontinent, from Costa Rica
to Argentina, on both slopes of the Andes. The species
inhabit an extremely diverse array of environments.
The 64 described species of Rineloricaria
(as of 2024) are not the easiest to identify as location
helps and also markings go a long way to identify
any chosen species.
