| Diagnosis: |
This species is similar to A. commbrae in having a dark tail spot which includes the last vertical bar on the body and a caudal spot. The species' lateral band ends in the sixth vertical bar rather than in the tail spot; abdominal stripes appear as traces or are absent, rather than as conspicuous spots along the abdominal sides or short vertical stripes below the anterior part of the lateral band; specimens examined have 15 rather than 16 dorsal spines; posteromedial teeth on the lower pharyngeal tooth-plate bear two small projections on the rostral edge (Ref. 86502). |
| Biology: |
Maximum length is 7.0 cm TL (Ref. 12251). This fish is a cave spawner in which the male has a harem (Ref. 12251). Female clutch tender, but male often takes part in caring for eggs and larvae (Ref. 47893). |
