A species of Helcogramma (sensu Hansen, 1986) with 1-2 symphysial mandibular sensory pores, second dorsal fin spines XIII (two of 26 specimens with XIV), third dorsal fin segmented rays 10-12, last ribs on vertebral centrum 11, vertebrae modally 11+26=37 (value range: 11+25 to 27=36 to 38), pored lateral line scales modally 25 (value range: 23-29), nape scales absent, males with dorsal, caudal and anal fins dark.
一個 Helcogramma( sensu 漢森,1986) 的種有 1-2 個 symphysial 顎骨感覺小孔，第二背鰭鰭棘 XIII(26 中的二標本用 XIV),第三個背鰭分段的鰭條 10-12,在椎骨的椎體 11 上持續肋骨, 脊椎骨典型地 11+26=37(價值範圍: 11+25 到 27=36 到 38), 有細孔的側線鱗片典型地 25(價值範圍: 23-29), 後頸鱗片不存在, 雄性有背鰭、尾鰭與臀鰭深色的。
Adults inhabit exposed rocky and coralline boulders of coasts (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). Minimum depth from Ref. 58018.
