Etymology: Trichonotus: Greek, thrix = hair + Greek, noton = back (Ref. 45335).

Chín muồi sinh dục: Lm ?  range ? - ? cm
Max length : 15.0 cm TL con đực/không giới tính; (Ref. 48636)
Các vây lưng mềm (tổng cộng) : 39 - 41. Trichonotus halstead is similar to T. setiger but has a beautifully colored dorsal fin (Ref. 48636). No free pterygiophores under dorsal fin (Ref 12934).
Body shape (shape guide): elongated.
Like other sand divers, it occurs on sand slopes with strong currents at times (Ref. 48636). Minimum depth reported from Ref. 26146.
