Philinopsis reticulata (NSSI 2nd ed, page 369)

The genus Philinopsis is a member of the family Aglajidae Pilsbry, 1895. Aglajids are often distinguished from other cephalaspideans by having a broad headshield with clusters of elongate sensory cilia, used for tracking prey. The posterior end of the body has a pair of blunt or elongate "tails" that generally provide protection for the posteriorly situated gill. The shell is internal and is wholly or partially calcified. Members of this family are carnivorous and generally lack a radula.

Philinopsis reticulata is white with brown markings and some blue on the headshield and tail; specimens with black reticulations have been identified as Philinopsis sp. 1. NSSI treats it as a separate Pacific species due to the width of the reticulations and internal differences.

This species, which reaches 30 mm in length, and resides in the Indian Ocean, and possibly the Western Pacific.
