Abstract (English): Introduction: Ophiocomella alexandri is a conspicuous species in the Eastern Tropical Pacific. The diagnosis is based on adult specimens and there are not documented variations. The inclusion of internal microstructures to the descriptions will allow intraspecific and interspecific comparisons in taxa with taxonomic problems. Objective: To describe the external morphology and internal microstructures of O. alexandri, including variation. Methods: We reviewed O. alexandri type material and general material deposited in three scientific collections. We examined the internal microstructures of the arm and jaw with a scanning electron microscope. Results: The external and internal morphology were described showing the morphological variations according to size. Conclusions: The variations in the internal morphology of O. alexandri show that this type of analysis is necessary, and even more important than the external morphology. It is recommended to carry out more taxonomic work that includes other species of the genus to clarify its taxonomic status. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): Introducción: Ophiocomella alexandri es una especie conspicua del Pacífico Tropical Oriental. La diagnosis esta basada en especimenes adultos y no existen variaciones documentadas. La inclusión de microestructuras internas a las descripciones permitirá hacer comparaciones intraespecíficas e interespecíficas en taxones con problemas taxonómicos. Objetivo: Describir la morfología externa y las microestructuras internas de O. alexandri, incluida la variación. Métodos: Revisamos el material tipo de O. alexandri y el material en general depositado en tres colecciones científicas. Examinamos las microestructuras internas del brazo y la mandíbula con un microscopio electrónico de barrido. Resultados: Se describió detalladamente la morfología externa e interna mostrando las variaciones morfológicas de acuerdo al tamaño. Conclusiones: Las variaciones de la morfología interna de O. alexandri muestran que es necesario este tipo de análisis, y más importante aún que la morfología externa. Se recomienda realizar mas trabajos taxonómicos que incluyan a otras especies del género para esclarecer su estado taxonómico. [ABSTRACT FROM AUTHOR]
