背面の脊椎 (合計) : 17 - 18; 背鰭 (合計) : 10 - 13; 肛門の骨: 1; 臀鰭: 19 - 22; 脊つい: 37 - 39. A species of Helcogramma (sensu Hansen, 1986) with 1-2 symphisial mandibular sensory pores, second dorsal fin spines XIV-XV (typically XIV), last ribs modally on vertebral centrum 12, vertebrae modally 11+27=38, 23-29 pored lateral line scales, nape without scales, and males with anal fin red in life becoming translucent in preservative.
Body shape (shape guide): elongated.
Female members of the Tripterygiidae have eggs that 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).
