Reported to be quite rare
in Thailand due to lost habitats and over fishing.
This species was previously misidentified as Ceratoglanis
scleronema from the Chao Phraya drainage. Description:
Dorsal spines (total): 0; Dorsal soft rays (total):
0 - 0; Anal soft rays: 90 - 101; Vertebrae: 63 - 64.
Snout with a gently sloping ventral profile (ventral
angle of snout 40°-42°), relatively fewer
anal-fin rays (90-101), and larger eyes (eye diameter
13.0-16.4% HL) set closer together (interorbital distance
33.7-36.6% HL). Absence of dorsal fin; short stiff
hooked maxillary barbels; posterior nostril above
front margin eye. Sexual Differences:
Mature males have membranous extensions on both the
anterior and posterior edges of the maxillary barbel.
Pectoral spine and articulated segments sexually dimorphic
in mature individuals. Males with spine broad and
somewhat flattened dorsoventrally, with 10 distinct
posterior serrate, increasing in size distally; proximal
articulated segments with 17 well-developed posterior
serrae; distal-most segments have smaller serrae.
Females or juveniles with spine slender and without
serrae; proximal articulated segments with 6 minute
posterior serrae; distal segments with 5 minute serrae.
Habitat: Inhabits mainstream river.
Diet: Carnivorous, feeding on insects
and benthic fauna. Remarks:
The specific name comes from the thicker barbels of
this species compared to its only congener, C.
scleronema. Not an aquarium fish as they are
reported to be very hard to keep and will die soon
after capture, as they are a deep water living fish
in their natural habitat.
Asia: Chao Phraya and Mekong River basins. Type
locality: Prachinburi Market, Thailand.
