 Diagnosis:  Dorsal soft rays (total): 17-20. Holotype from 'reef', a brooding male lacks dorsal and pectoral fins, while those fins present in its pouch-larvae. Planktonic specimens at similar size of adults have dorsal fin and pectoral fins. The female looks much like female Acentronura, but have a moderately large caudal fin. The pouch of the male holotype is sac-like, also similar to Acentronura (Ref. 48635). Description: Characterized by generally whitish color; pair of dark bands below eye; pectoral fin membranous, in pouch larvae and planktonic specimens, absent in adult; absence of anal fin; 10 caudal rays; rings 11 + 35 - 38; continuous superior trunk and tail ridges; end of inferior trunk ridge near anal ring; lateral trunk ridge confluent with inferior tail ridge; closed male brood pouch, sac-like, opening through anteromesial pore (Ref. 90102).
 Biology:  Specimens taken at the surface with nightlight and dipnet. May also be found on shallow mudflats with sparse seagrasses. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Found in association with Briareum soft corals (Ref 90102).
