"Pseudolaguvia" is a genus of catfishes (order Siluriformes) in the family Erethistidae.

Distribution

"Pseudolaguvia" is not a diverse group, and this diversity is confined to a small area. "Pseudolaguvia" species are distributed in the Ganges and Brahmaputra drainages, India, Nepal, Bangladesh, and east and south to the Sittang drainage, Myanmar. "P. ferula" inhabits the Brahmaputra drainage, northeast India.cite journal|url=http://www.mapress.com/zootaxa/2006f/zt01229p068.pdf|title="Pseudolaguvia ferula", a new species of sisoroid catfish (Teleostei: Erethistidae) from India|first=Heok Hee|last=Ng|journal=Zootaxa|volume=1229|pages=59–68|year=2006|format=PDF] "P. foveolata" originates from the Tista River, Brahamputra River basin, India.cite journal|title="Pseudolaguvia foveolata", a new catfish (Teleostei: Erethistidae) from northeast India|first=Heok Hee|last=Ng|journal=Ichthyol.

"P. kapuri" is from the Padhoi River and Dhamola River, Saharanpur, Uttar Pradesh. "P. muricata" inhabits the Brahmaputra River basin, Bangladesh. "P. ribeiroi" is distributed in the Teesta River system, north Bengal, the Kosi River system Behar, the Rihand River system, Uttar Pradesh, and rivers of Nepal. "R. shawi" originates from North Bengal, India, and Bangladesh and the Brahmaputra River basin, Assam, India. "P. tenebricosa" is presently only known from a fast-flowing hill stream called Pathe Chaung, near Taungoo in southern Myanmar.cite journal|url=http://www.mapress.com/zootaxa/2003f/zt00388.pdf|title=A new species of the Asian catfish genus "Pseudolaguvia" from Myanmar (Teleostei: Ostariophysi: Siluriformes: Erethistidae)|first=Ralf|last=Britz|coauthors=Ferraris, Carl J., Jr.|journal=Zootaxa|volume=388|pages=1–8|year=2003|format=PDF] "P. tuberculata" is from the Myitkyina District, Kachin State, Myanmar.cite journal|url=http://silurus.acnatsci.org/ACSI/library/biblios/2007_Ferraris_Catfish_Checklist.pdf|title=Checklist of catfishes, recent and fossil (Osteichthyes: Siluriformes), and catalogue of siluriform primary types|first=Carl J., Jr.|last=Ferraris|journal=Zootaxa|volume=1418|pages=1–628|year=2007|format=PDF]

Description

Externally, these fish resemble members of the sisorid catfish genus "Glyptothorax".cite journal|url=http://www.mapress.com/zootaxa/2005f/zt01044p047.pdf|title=Two new species of "Pseudolaguvia" (Teleostei: Erethistidae) from Bangladesh|first=Heok Hee|last=Ng|journal=Zootaxa|volume=1044|pages=35–47|year=2005|format=PDF] "Pseudolaguvia" is diagnosed by the presence of a short thoracic adhesive apparatus with median depression; wide gill openings nearly meeting one another on the underside of the body; serrations on anterior margin of pectoral fin spine pointing toward tip; smooth to granulate anterior margin on the dorsal fin spine; slender body; papillate upper lip; and 8–10 anal fin rays.cite journal|url=http://www.mapress.com/zootaxa/2006f/zt01345p096.pdf|title=Genera of the Asian Catfish Families Sisoridae and Erethistidae (Teleostei: Siluriformes)|first=Alfred W.|last=Thomson|coauthors=Page, Lawrence M.|journal=Zootaxa|volume=1345|pages=1–96|year=2006|format=PDF] Both the dorsal fin and pectoral fin have strong spines. The head and body are slightly depressed. The eyes are small, dorsal, and located in the middle of the head. The barbels are annulated with black rings.

Ecology

"Pseudolaguvia" species inhabit hill streams and large rivers. "P. tenebricosa" is found in fast running, clear water; the river has a sandy bottom and numerous rocks and boulders, and aquatic vegetation is absent. "P. inornata" is from clear, shallow, moderately flowing streams with a predominantly sandy bottom. "P. muricata" is found in clear, shallow, slow-flowing streams with a mixed substrate of sand and detritusl; these fish are found amongst detritus in areas with current. "P. ferula" is also found in swift flowing waters with a mixed rocky/sandy bottom.
