Parakysis genus of catfishes (order Siluriformes) of the family Akysidae . It includes six species .[1]
Distribution
[ edit ]
Parakysis species are found in small forest streams of Sundaic Southeast Asia .[2] P. anomalopteryx originates from the Kapuas River basin in western Borneo. P. grandis inhabits the Kapuas and Kuching River basins in Borneo and Deli , Indragiri , and Batang Hari basins in Sumatra . P. longirostris is distributed in Singapore , peninsular Malaysia , and the Riau Archipelago . P. verrucosus is known from Peninsular Malaysia and the Riau Archipelago.[3] P. notialis in 2003 expanded the known range of Parakysis species to the Barito River basin in southern Borneo.[2]
Description
[ edit ]
They are cryptically colored fishes that have a highly rugose skin with tubercles all over the body, branched mandibular barbels , a long, low adipose ridge , and a forked caudal fin .[2] Parakysis species characteristically have pigmented tubercles and lateral lobes of the lower lip. They are also distinguished from Akysis palatine , non-serrated pectoral and dorsal spines , and the apparent absent of the lateral line .[4] in ) SL [5] [6] [7] [8] [9]
Ecology
[ edit ]
P. anomalopteryx is found in small forest streams.[5] P. longirostris is nocturnal and occurs in clumps of vegetation in streams with flowing waters. It is sympatric with P. verrucosus. [7] P. verrucosus is found in primary peat streams with dense litter falls.[9]
