Relevant Information:

Description: This species is distinguished from P. moolenburghae in having fewer anal-fin rays 37-41 (vs.42-49); fewer rakers on the first gill arch 33-35 (vs. 43-45); a wider head 10.5-11.0% SL (vs. 8.5-9.9% SL); differs from P. brachypopterus in having more anal-fin rays 37-41 (vs. 31-35); shorter (23.1-24.3% SL vs. 27.0-30.6) and narrower (10.5-11.0% SL vs. 11.7-14.0) head; differs from P. mitchelli in having more anal-fin rays 37-41 (vs. 35-37); longer nasal, maxillary and mandibular barbels, reaching to at least anal-fin origin (vs. not reaching beyond pelvic-fin base). Habitat: The species was recently described from peat swamp forest in Narathiwat Province, southern Thailand. Its full distribution is uncertain, however there are possible records of the species from associated drainages as far north as the Isthmus of Kra within peninsular Thailand, and the species should be looked for in suitable habitat in northeastern Peninsular Malaysia. Aquarium Care: Quite a shy fish so would need a planted tank to make them feel safe in their surroundings. Have at least 6 to form a group. Diet: Feeds on insect larvae and small invertebrates. Etymology: The specific name indigens: Latin for indigent, i.e., in need of or wanting, referring to lower number of anal-fin rays and gill rakers compared with the similar P. moolenburghae.

IUCN Red List

Recent survey and monitoring data are lacking, and the species' ecology is poorly known. Whilst its restricted distribution and declining habitat might qualify it for a threatened category (Vulnerable D2), it is assessed as Data Deficient at present. However, it should be reassessed when further data become available (IUCN 2019).
