Ecsenius opsifrontalis Chapman & Schultz ,

USNM 377567, male, 35.8 mm SL, Majuro, Marshall Islands.

This specimen has an unusually well-developed dusky to almost black color pattern, which is most similar to that of one of the males illustrated by Springer (1988:figure 50d) from Rotuma , but the pattern of the Majuro specimen is even more striking. An underwater color photograph taken by Satoshi Yoshii of another specimen at Majuro exhibits the orangish stripes and bars on the body typical of E. opsifrontalis .
