Description

Nototriton barbouri display a snout truncate that is broadly rounded in the dorsal aspect, and a lateral profile that is truncate to mostly rounded. The nostril openings are small and when viewed from below, the protuberant eyes are narrowly visible beyond the margin of the jaw. Males exhibit well developed labial protuberances, while it is weakly developed in females of this species. In breeding condition, males may display an oval-shaped mental gland cluster. A shallow postorbital grove extends posteriorly from the eye, and connects to the gular fold. Another sharp ventral groove is present just posterior to the lower jaw. Males possess marginally larger numbers of maxillary and volmerine teeth while females display slightly more premaxillary teeth than males. The tail is slightly constricted at the base. The anterior cross section is nearly rectangular, and the distal one-third of the tail becomes ovoid. N. barbouri exhibit slender, and short limbs. The tips of the toes display well developed subdigital pads and are bluntly rounded.

This species may be differentiated from Cryptotriton nasalis and Dendrotriton sanctibarbarus by its relatively small nostril openings and undersized limbs. N. barbouri is larger than N. lignicola and possesses a longer tail. It is also distinguished from N. limnospectator by having relatively larger nostril openings and a wider head. The relatively narrow feet and characteristic sublingual fold help recognize N. barbouri from the remaining Honduran salamander in the same genus.

In alcohol, the dorsal and lateral surfaces may be observed to be pale to dark brown to black. The ventral surfaces may be slightly more pale brown than the dorsal surfaces. Cream flecking may or may not be present.
