Niparaya
cf. regiscorona (Bertsch, 1972)
 
Niparaya cf. regiscorona
Maximum size:  4 mm.

Identification:  This small species is usually translucent brown intricately flecked with darker brown and cream. However, the color is variable, ranging from light brown with dark brown reticulation to gray with white flecks. Occasional animals may be mostly white or have pink spots on the notum. The surface is tuberculate although the tubercles vary considerably in development and there are usually a few enlarged tubercles on the posterior tip of the head shield. Most animals have rust-orange bands on the interior of the parapodia.

Natural history:  Niparaya cf. regiscorona is a moderately common species found at depths of 1-6 m (3-20 ft) in moderately protected to exposed rocky habitats. It lays a small, somewhat irregular white egg mass. Hatching occurs in about three days in the laboratory.

Distribution:  Maui, Kauai and Midway.

Taxonomic notes:  It was first recorded in Hawaii from Hekili Point, Maui by CP on June 2, 1991. The Hawaiian population is probably different from the Western Pacific and Eastern Pacific populations formerly included with it under the name Aglaja regiscorona. (Zamora-Silva & Malaquias, 2017) There's some chance that one or more of the color forms could also turn out to be different.
