📖 Overview

Collected from relatively flat sandy bottoms exposed to periodic strong tidal currents in 15-24 m depth with temperature ranging from 20 to 28 °C across the year. Most individuals observed appeared to be solitary, while about 20% of burrows encountered had a pair of shrimpgobies guarding the entrance. Observations during peak tidal currents showed that nearly all shrimpgoby burrows were completely covered by shifting sands; only during slack tides would the alpheid shrimp reopen the burrow entrances. Many other species of shrimpgoby were commonly observed within 1 or 2 m of burrows of the new species, including Amblyeleotris diagonalis, A. novaecaledoniae, A. ogasawarensis, A. rubrimarginata, A. steinitzi, A. wheeleri, Ctenogobiops mitodes, C. pomastictus, and Stonogobiops xanthorhinica .
