Mahatvaraj (1) Adrian
Dorsal soft rays (total): 5; Anal soft rays: 10 -
11; Vertebrae: 28 - 30. Differs from its congeners
by having elongate dorsal (21.2-26.7% SL) and pectoral
(26.8-35.7% SL) spines. Differs from Pseudolaguvia
foveolata in having a thoracic adhesive apparatus
reaching beyond the base of the last pectoral-fin
ray, a shorter caudal peduncle (12.6-15.7% SL vs.
20.7) and fewer vertebrae (28-30 vs. 33); from P.
kapuri in having a shorter adipose-fin base (12.3-16.1%
SL vs. 17.1-18.8); from P.
ribeiroi in having a shorter caudal
peduncle (12.6-15.7% SL vs. 16.4-18.2); and from P.
inornata in having (vs. lacking) light brown
patches on the body and a shorter caudal peduncle
(12.6-15.7% SL vs. 16.3-19.0). Further differs from
in lacking a colour pattern of strongly contrasting
brown and yellow bands and in having a larger interorbital
distance (31.4-36.7% HL vs. 23.4-29.6); from P.
tenebricosa in having a shorter caudal peduncle
(12.6-15.7% vs. 16.9-18.9); and from P. tuberculata
in having a shorter adipose-fin base (12.3-16.1% SL
vs. 16.8-22.7) and caudal peduncle (12.6-15.7% SL
vs. 16.2-20.1). Habitat: This small
species is found in clear, shallow, slow-flowing stream
with a mixed substrate of sand and detritus.
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.
