背棘 (總數) : 2; 背的軟條 (總數) : 7; 臀棘: 1; 臀鰭軟條: 4. Distinguishes from its congeners by having dark vermiculations on the abdomen (vs. spots, long, fairly straight, wide lines, or plain); also from all congeners except Peckoltia bachi by having the dorsal and lateral surface of the body mottled (vs. with spots or saddles); and from P. bachi by having the spots on the head small (vs. large) and generally forming vermiculations (vs. separate), the pelvic spines narrow (vs. wide), and the eye high on the head (vs. low) (Ref. 77026).
Facultative air-breathing in the genus (Ref. 126274); Inhabits slow-flowing muddy streams. Also encountered inside submerged, hollow logs during the day (Ref. 77026).
