Two genera are recognized in the family Monocentridae . Monocentris differs from Cleidopus De Vis, 1882 , in having a broad (deep) suborbital space (> 8.2 % SL); a large mouth with upper jaw straight; relatively long snout, subequal to eye diameter; a black light organ at tip of lower jaw; toothless vomer; and relatively smaller maximum size (usually less than 15 cm SL), whereas Cleidopus has a very narrow suborbital space with lower margin of eye almost adjacent the upper jaw (2.9–3.2 % SL); small with S-shaped upper jaw; snout clearly shorter than eye diameter; an orange light organ on each side of lower jaw under eye; vomer with teeth; and a relatively larger maximum size (up to 26 cm).

According to Paxton (1999), the lateral line is absent in monocentrids, however, our specimens possess a small canal through each scale in a row where a lateral line is commonly found in beryciform fishes (LLS in Fig. 1 View FIGURE 1 ). Thus, we recognized this row of scales as lateral-line scales.

Previously, the genus has comprised two species: M. japonica in the Indo-West Pacific and M. reedi in the southeastern Pacific. A third species similar to M. japonica is described below.
