Members of the genus Pseudolaguvia are small
erethistid catfishes inhabiting hill streams and large
rivers in the area bordered by the Ganges River drainage
(northern India) to the west and the Sittang River
drainage (east-central Myanmar) to the east.Description:
Pseudolaguvia ferruginea is from the Brahmaputra
River drainage in India and is distinguished from
other members of the genus in having a combination
of a more slender, elongate body (manifested as a
smaller body depth at anus: 10.5-12.4% standard length),
length of dorsal-fin base 14.9-17.3% standard length,
length of dorsal spine 13.0-16.6% standard length,
length of pectoral spine 16.3-18.8% standard length,
dorsal to adipose distance 14.2-17.3% standard length,
caudal peduncle depth 2.4-2.8 times in its length,
head width 20.1-22.2% standard length, a smooth front
edge of the dorsal spine, and the thoracic adhesive
apparatus reaching to midway between the bases of
the last pectoral-fin ray and the first pelvic-fin
Ferraris (2007) stated that the Erethistidae
be moved back into the Sisoridae family and depending
on what literature you have accessed, be it books
or the internet, there are conflicting views on what
family it belongs to, Erethistidae or Sisoridae. In
Eschmeyer's Catalog of Fishes the current name is
valid and it is placed in the Sisoridae family.
