Bolitoglossa insularis is a moderately large, robust salamander (female SVL 64.7 mm). The snout is rounded dorsally, with prominent labial protuberances. The head is narrow, flat, and slightly demarcated. Eyes are moderate in size, protrude slightly, and are visible beyond the jaw margin when observed from below. This salamander has an indistinct postorbital groove, a defined subocular groove, and a distinct gular fold that extends dorsolaterally to lower level of eye, but lacks a sublingual fold. A groove located posterior to the mandible appears as a weakly defined depression anterior to the gular fold. Maxillary teeth (41) reach eye level and vomerine teeth (23) reach the choanae. Limbs are relatively slender and long; adpressed limb separation is about 3.5 costal folds. Digits of hands and feet are rounded and fully webbed but lack subdigital pads. Fingers increase in length from I

In life the dorsal surfaces of Bolitoglossa insularis are brown with dark brown spots. Two poorly defined dark brown dorsolateral markings extend from behind the forelimb insertions nearly to the groin area. Ventral surfaces of the body, limbs, and tail are light grayish brown, mottled with small dark brown spots. The ventral surface of the head is reddish brown, with a pair of thin ventrolateral stripes created by the absence of brown spots. Labial protuberances are pale brown. Hands and feet are brown ventrally (Wake et al. 2008).

The species name insularis derives from Latin and means "of islands." (Wake et al. 2008).
