Mexichromis tura
Mexichromis tura (Marcus & Marcus, 1967)
Over ten years ago, Kerstitch and Bertsch (1988) called this species "rarely observed." Since this publication, no further records of the species have been reported. Mexichromis turia is truly a hard-to-find nudibranch in the Panamic province. Specimens have been found only from 5 localities: Ft. Kobbe Beach, Panama (8 48' N; 79 55' W); Sayulita, Nayarit, Mexico ((21 15' N; 105 15' W); La Cruz, Nayarit, Mexico (21 30' N; 105 16' W); La Paz, Baja California Sur, Mexico (24 11' N; 110 23' W); and Bahía San Carlos, Sonora, Mexico (27 55' N; 111 04' W).
The mantle margin of the animal is rimmed with three encircling bands: an outermost yellow, a middle black, and an innermost powder blue. The black dorsum has numerous yellow spots; the periphery of the dorsum has larger, whitish streaks and splashes. The gills are white, with black tips. The rhinophores are completely black.
