Description:
Glyptothorax is distinguished from all other
sisorid genera by having an adhesive apparatus on
the thorax with with grooves parallel or oblique to
the longitudinal axis of the body (vs. thoracic adhesive
grooves transverse to the longitudinal axis of the
body in Pseudecheneis, and thoracic adhesive
apparatus absent in all other genera). Etymology:
The specific name dorsalis: Latin for of
the back, referring to elevated dorsal fin, its height
greater than height of body. Remarks:
This species has been considered a synonym of G.
platypogonoides by many authors. We consider
this species (Thomson & Page 2006) valid and tentatively
consider all records of G. platypogonoides
from India and Myanmar to be based on G. dorsalis.

IUCN
Red List
Glyptothorax
dorsalis is known from the Salween and Irrawaddy
river drainages in Myanmar. Although it has been reported
from the Salween River drainage in China (Chu and Mo
1999), this record is questionable as it likely refers
to G. ngapang and requires verification. Although
the current population and its trends are not well known,
current indications from field surveys are that this
species is still relatively widespread and abundant.
Therefore, this species is assessed as Least
Concern here, but needs updating, (IUCN
2010).
