|Cat-eLog Data Sheet|
|Scientific Name||Pseudolaguvia austrina Radhakrishnan, Sureshkumar & Ng, 2011|
|Type Locality||Kunthi River, tributary of Bharathapuzha River, at Mannarkkad, 11°21'N, 76°53'E, Kerala, India.|
|Pronunciation||sue doh lah GOO vee ah - aus tree na|
|Etymology||The specific epithet comes from the Latin adjective austrinus, meaning southern, in reference to the distribution of this species (Western Ghats), which is the southernmost in the Indian subcontinent.|
|Identification||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. They can be distinguished from other sisorids by their small size,a combination of a thoracic adhesive apparatus with a median depression and prominent postcoracoid processes.
Pseudolaguvia austrina is diagnosed from congeners in having a color pattern consisting largely of uniform pale brown body ( vs. color pattern of mottled brown body or brown body with a pattern of pale patches or transversebands), a strongly projecting snout in which the premaxillary teeth are almost entirely exposed (vs. barely exposed) when the mouth is closed , and a shorter (8.8-14.7 % SL vs. 13.9-25.6) and deeper caudal peduncle (10.3-14.7 % SL, vs.5.0-9.0). The field of the thoracic adhesive apparatus of P. austrina is also more rhomboidal, which differs from the more elongate, elliptical shape seen in all congeners except P. foveolata.
|General Remarks||It is very likely that this species has not been exported for the trade as yet but general care will be very similar to that of other Pseudolaguvia species. This is the first record of this genus in peninsular India.|
|Distribution||Known from Kunthi River, a principal tributary of Bharathapuzha River, Kerala, Peninsular India.

|IUCN Red List Status||Data Deficient|
|Other Parameters||The water should be cool and heavily oxygenated with a good flow as these fish occur in hill streams. Anything above 25 C will hamper long term survival as these fish tend to burn away at higher temperatures. Pseudolaguvia austrina was collected from the small crevices of a sand barrier built across the river with a moderate water depth (ca.15 cm) and current velocity (0.25-0.40 m · s–1). The habitat was riffle-pool type. The water was well oxygenated with dissolved oxygen 7-8 ppm and a pH of 7.5-8.0. Some of the specimens were also collected from the adjoining clayey area with clumps of leaf litter. Samplings were carried out during the hot and dry fortnight periods in premonsoon season, during March, when water was clear and atmospheric temperature 32-35 °C.|
|Feeding||Known to take only live food like blood worms, frozen brine shrimp etc. Spot feeding will help in case tank mates are voracious feeders.|
|Furniture||Fine sand for the bottom and smooth pebbles / rocks.|
|Compatibility||A peaceful species suitable for a hillstream biotope. Extreme care should be taken while choosing their tankmates as these fish are extremely poor at competing for food.|
|Suggested Tankmates||Cyprinids like Barilius and Danios and Balitorine loaches like Homaloptera species. Other species collected along with P.austrina include Glyptothorax madraspatanum (Sisoridae), Lepidocephalichthys thermalis (Cobitidae) and Glossogobius giuris (Gobiidae).|
