A) as long as wide; anterior margin between rostrum and lateral projections slightly concave; anterolateral margins sloping; posterior margin roundly truncate; dorsal surface slightly convex transversely, with several tufts of long setae arranged symmetrically; paragastric grooves obsolescent. Rostrum broadly triangular, reaching beyond level of lateral projections, with paired tufts of moderately short setae. Lateral projections obsolete, each with or without small submarginal spine. Posterior carapace (not figured) about 0.8 length of shield; carapace lateral lobe moderately narrow, well calcified; cardiac sulci subparallel, extending to midlength of posterior carapace; sulci cardiobranchiales slightly diverging posteriorly, extending to midlength of posterior carapace; median area flanked by sulci cardiobranchiales slightly calcified, with some tufts of moderately short setae arranged symmetrically; branchiostegites membranous, with scattered tufts of short to moderately long setae.

A) moderately slender, about 0.6 times as long as shield; inflated basally, basal width greater than corneal width; cornea not dilated, its width about 0.2 of peduncular length; dorsal surface with longitudinal row of tufts of short to moderately long setae mesially, but no setal tuft at base of cornea. Ocular acicles roundly subtriangular or subovate, separated basally by width of one acicle, each with small submarginal spine distally; dorsal surface nearly flat. Interocular lobe clearly visible, medially concave.

In particular, both species have relatively numerous and strong corneous spines on the dactyli and propodi of the ambulatory legs. The general coloration is strikingly similar between the two species, although living coloration is often used to differentiate morphologically similar or cryptic species in the Paguroidea (e.g.,
