Short Description
Original diagnosis of CORDOVA & EBERT, 2021 [29831]: A new species in spongiceps subgroup of Apristurus, as defined by Nakaya & Sato (1999), distinguished from all congeners by a combination of characteristics: an overall uniformly whitish “porcelain” colored body with lighter colored anal and caudal-fin margins and a distinct white spot on tail tip vs. a uniform dark brown to grayish, or blackish, body coloration, variably with blotches, flecks, spots, or squiggles, in all other spongiceps subgroup species (except A. albisoma and A. aphyodes with similar light coloration, but subtle differences); clasper hooks present vs. absent; oral papillae absent or sparsely covering oral cavity roof vs. distinct and densely covering oral cavity roof; dorsal caudal margin with widely spaced, non-overlapping dermal denticles vs. closely spaced, overlapping denticles; lower tooth counts, i.e. 46–57 in upper jaw and 44–50 in lower jaw vs. 56–71 and 49–70 respectively.

Dentition
Teeth numerous and large; similar in upper and lower jaw; upper anteriors with long, robust, central cusp, flanked by one or two acutely pointed lateral cusps on each side, less than one-half height of central cusp; upper laterals with long central cusp flanked by two successively smaller cusps on each side, about one-half or less than height of preceding cusp; lower teeth similar to uppers, with central cusp of anteriors having one or two lateral cusps on each side, and laterals flanked by two lateral cusps on each side. Sexual dimorphism apparent: adult male jaws more pronounced than adult females, very strongly arched, adult female jaws more weakly arched. Tooth counts in first row of upper jaw 51 (46–57) and in first row of lower jaw 49 (44–50). [29831]
