One of the smallest Australian leatherjackets. Males are identified by the black stripes in front of the eyes, blue spots on the sides of the body, and a black crescent-shaped marking near the edge of the tail. Females and juveniles have a mottled-brown pattern and are difficult to distinguish from juvenile toothbrush leatherjackets. These two species are best separated by the presence of numerous black spots on the sides of the body in bridled leatherjackets, whereas juvenile toothbrush leatherjackets have a pattern of small white blotches.

• IUCN Threat Status: Not Evaluated
• Occurrence: Infrequent (8% of sites)
  Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
• Abundance: Several (5 per transect)
  Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
