Holothuria (Mertensiothuria) viridiaurantiasp. nov. is described based on specimens from rocky reefs of northern Chocó in the Colombian Pacific Ocean; however, it also occurs along the Eastern Pacific Ocean from Mexico and Panama. Although specimens from Mexico and Panama were previously identified as Holothuria (Mertensiothuria) hilla Lesson, 1830 the new species is easily distinguished morphologically and via mtDNA. In terms of morphology, the species can be identified by its olive-green background and white-orange papillae and tentacles, larger tentacles with deep indentations and also by larger buttons on the dorsal and ventral body wall, papillae and tube feet; large, thick and rough tentacle rods, and the absence of ossicles in the longitudinal muscles. The new species is included in the subgenus Mertensiothuria considering molecular evidence.

A New Species

Eusyllis Malmgren, 1867 (Annelida, Syllidae) is revised, with 7 species considered as valid (Eusyllis assimilis Marenzeller, 1875; Eusyllis blomstrandi Malmgren, 1867; Eusyllis kupfferi Langerhans, 1879; Eusyllis lamelligera Marion & Bobretzky, 1875; Eusyllis longicirrata Imajima, 1966; Eusyllis maxima (Monro, 1930); and Eusyllis nuchalata Hartmann-Schröder, 1965) plus a newly described species (Eusyllis grandmarie n. sp.) the only species of the genus recorded from a whale carcass, lying at more than 600 m deep in the eastern Pacific Ocean off the California coast. The new species is characterized by elongated compound chaetae, with blades almost unidentate, and a thin, spine-like proximal tooth. It differs from Eusyllis longicirrata Imajima, 1966, from Japan, in having shorter dorsal cirri and blades of compound chaetae. Additionally, Eusyllis nuchalata Hartmann-Schröder, 1965 is re-described. A key to the species of the genus is included.
