Short description
Identification keys | Morphology | Morphometrics
This species is distinguished from its congeners by the following set of characters: dorsal coloration of the disc is brown with numerous small, dark brown spots in axon or vermiculated formats spread throughout the disc, not very conspicous and lacking withish withish spots; small and quadrangular spiracle with a mean spiracle length of 4.6% DW (3.6-5.8% DW), with a reduced, rounded spiracular process that covers only a small part of the posterior portion of the spiracular aperture; dermal denticles on the central disc with a crown that possesses a central coronal plate and lateral coronal ridges in a leaf shape, with the lateral coronal ridges smaller and ranging from two; and the propterygium is arched and stout, with the posterior portion thicker than the anterior (Ref. 138774).
Body shape (shape guide): other (see remarks); Cross section: flattened.
