Etymology: Pseudobarbus: Greek, pseudes = false + Latin, barbus = barbel (Ref. 45335); senticeps: The species name senticeps refers to the thorny or prickly appearance of the head (sentis, a thorn, bramble, and ceps, head) of sexually mature males due to the development of distinctly pointed tubercles on the snout, along the inner edges of the nares and orbits and head dorsum (Ref. 114782).

Các tia vây lưng cứng (tổng cộng) : 0; Các vây lưng mềm (tổng cộng) : 10 - 11; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 8; Động vật có xương sống: 35 - 38. Diagnosis: The possession of a single pair of oral barbels separates Pseudobarbus senticeps from P. skeltoni, P. verloreni, P. burgi and P. burchelli (Ref. 114782). The possession of fewer and larger scales, 25-30 scale rows along the lateral line, separates P. senticeps from P. quathlambae, P. asper, P. swartzi and P. tenuis, which have respectively more than 60, 35-45, 34-37 and 32-37 scale rows along the lateral line; there is overlap in lateral line scales series between P. senticeps, P. afer and P. phlegethon, which have respectively 25-30, 29-35 and 29-37 lateral line scales series (Ref. 114782). A lateral stripe which terminates in a triangular blotch at the base of the caudal fin and longer barbels, reaching or surpassing vertical through the posterior edge of the eye, further separate P. senticeps from P. afer, which barbels do not surpass vertical through the centre of the eye (Ref. 114782). Body colour pattern distinguishes P. senticeps from P. phlegethon, which is characterised by prominent black spots and patches on the body, which are lacking in P. senticeps (Ref. 114782).
This species inhabits perennial mountain streams with clear to peat stained water, cobble and pebble substrates (Ref. 114782).
