An individual Coronida glasselli was collected by scuba diving in 10 November 2014 in shallow waters of Punta Ulloa, Isla del Coco (5°33’23.13” N - 87°02’51.84” W), at 6 to 12 m deep. This species was associated with coarse sand substrate in a coral reef environment. The organism was deposited in the carcinological collection of the Museo de Zoología (UCR 3378-01), Universidad de Costa Rica.

The present report of C. glasselli Manning, 1976 is the first record of this species on Isla del Coco. Coronida glasselli is a small species that has a total length of 3.60 cm, with the sixth abdominal somite and the telson being covered by grouped thorns and less than 10 thorns in the basal segment of the uropodal exopod (Fig. 1) (Manning, 1976; Salgado-Barragán, & Hendrickx, 2010). Coronida glasselli has been reported previously from Isla Gorgona, Colombia, between 10 and 13 m depth (Manning, 1976; Salgado-Barragán, & Hendrickx, 2010). In addition, specimens from Isla Uva, Panama, found in sandy-bottoms, and coral substrates at 25 m, are deposited in the National Museum of Natural History, Washington, DC, but is unpublished (NMHH 2015).

RESUMEN

Presencia del crustáceo Coronida glasselli (Stomatopoda: Coronidae) en el Parque Nacional Isla del Coco, Pacífico Tropical Oriental, Costa Rica. El orden Stomatopoda es un pequeño grupo de crustáceos marinos y estuarinos que habitan en una amplia diversidad de sustratos. En el Parque Nacional Isla del Coco se han hallado seis especies pertenecientes a cinco familias. El presente trabajo reporta a Coronida glasselli, el cual anteriormente solo se había reportado para Isla Gorgona, Colombia y en el Museo Nacional de Historia Natural, Washington, DC, se encuentran depositados individuos de Isla Uva, Panamá.

Palabras clave: Arrecife, invertebrados bentónicos, estomatópodos, diversidad, Isla del Coco.
