Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 17 - 18; Raggi dorsali molli (totale) : 11 - 13; Spine anali: 1; Raggi anali molli: 20 - 21. A species of Helcogramma (sensu Hansen, 1986) with 2 symphisial mandibular sensory pores, second dorsal fin spines XIV (three specimens with XV), third dorsal fin segmented rays 10-11, last ribs on vertebral centrum 10-11, vertebrae modally 10+28=38, pored lateral line scales modally 22 or 23, nape scales present, males with dusky anal fin.

Adults are found at depths of 7 m and shallower, in surge channels and exposed coasts of rocky boulders (Ref. 90102). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
