A new species of Parotocinclus from the upper
Rio Paraguaçu, Bahia, Brazil, is described.
The new species is distinguished from all congeners
by its unique colour pattern, with irregular dark
blotches resulting in a somewhat marble-spotted pattern
on head and trunk of most specimens and dorsum of
head with a conspicuous V-shaped light mark from tip
of snout to nares. The new species is also distinguished
from congeners by having the lower lip elongated posteriorly
and reaching or surpassing the anterior margin of
cleithrum on the pectoral girdle, the canal cheek
plate on the ventral surface of the head reduced and
with a slightly concave margin, and abdomen covered
by small embedded platelets, without contact with
each other and not arranged in a line between the
pectoral-fin axilla and pelvic-fin origin. The presence
of a thick and rough skin in the interradial membrane
of pelvic fin exclusively in the females of P.
nandae is reported by the first time to occurs
in Siluriformes. Aquarium Care: This
is a dwarf species which can be problematic to keep
as it will need to be kept by their own or at least
with other dwarf species as they will find it difficult
to compete for food in the hurly burly of a community
tank. Diet: Artemia naupli
and vegetable matter. Etymology:
The specific name nandae honours Maria Fernanda Boaz
Lehmann, daughter of the first author of this paper
and affectionately known as “Nanda”. A
noun in genitive.
Parotocinclus nandae is known from two localities
in the upper portion of the Rio Paraguaçu basin,
Chapada Diamantina domain, Bahia State, Brazil.
