Morphological variation and worldwide distribution of the lightfish genus Woodsia Grey, 1959 (Teleostei: Stomiiformes: Phosichthyidae).

Morphological variation in the poorly known lightfish genus Woodsia Grey, 1959 is evaluated by examination of 13 specimens of Woodsia nonsuchae and 28 specimens of Woodsia meyerwaardeni from all oceans. Morphological data for both species are documented for the first time from the Indian Ocean. The geographic distribution of Woodsia species is reviewed based on new data as well as from literature records and museum databases. .
