Relevant Information:

Description: Dorsal spines (total): 1; Dorsal soft rays (total): 7. . Differs from P. heokhuii in having a shorter adipose-fin base (14.2-17.7% SL vs. 18.2-22.8), more slender caudal peduncle (7.3-8.9% SL vs.8.8-10.5), wider head (24.4-26.2% SL vs. 21.7-23.8) and larger eye (11.2-14.7% HL vs. 8.5-10.7) and a slightly convex (vs. evenly sloping or slightly concave) predorsal profile. Colouration: Distinguished from congeners except for Pseudomystus heokkuii (from Sumatra) in having a colour pattern consisting of a pale midlateral stripe and two pale oblique bands on the sides of the body. Etymology: The genus name Pseudomystus: Greek, pseudes = false + Greek, mystax = whiskered, used by Belon in 1553 to describe all fishes with whiskers. The specific name funebris: somewhat greater, referring to the relatively larger adipose-fin base and pectoral and dorsal fins when compared to B. macracanthus, its closest congener.

IUCN Red List

This species is known only from the Kahayan River drainage in southern Borneo. It has an extent of occurrence (EOO) of 10,300 km2 and an area of occupancy (AOO) of 3,270 km2. The habitat of this species (blackwater peat swamp and heath forests) has undergone large scale destruction and degradation due to logging, plantation agriculture (primarily oil palm plantation), and channelisation. Given the scope of land conversion for use in plantation agriculture, the number of locations is likely not more than five. Additionally, these threats are severe, widespread and capable of driving this species to extinction within a short time period. Therefore, Pseudomystus funebris is assessed as Vulnerable under criteria B1ab(i,ii,iii) and D2 (IUCN 2020).
