line with 12 pored scales and 21-22 notched scales, notched segment starting second scale row below end of pored segment, overlapping by one scale. Total lateral scales 32; transverse scales 1/4. Vertebrae 10+22. Mandibular pores 2+1/2+2. Head 3.2-3.5, body depth 5.1-5.3 in SL; eye 3.1-3.7 in head length; maxilla 2.6-2.9 in head length. Small fish, less than 20 mm SL. Body slender; scales large; nape scaled; belly with smaller, thin cycloid scales. Pelvic fins slender, rays united by a thin, fragile membrane for about one third length of shorter ray. First dorsal fin slightly higher than second, second 75-90% of body depth. Longest pectoral-fin ray reaches nearly to base of first ray of third dorsal fin. Supratemporal sensory
canal crescent-shaped. Mouth oblique, reaching vertical through anterior margin of pupil; interorbital concave and broad, about equal to pupil diameter; orbital cirrus a simple rounded flap and about half pupil diameter in length (Ref. 57774).

具有 12個有細孔的鱗片與 21-22個有凹槽的鱗片線,在有細孔片段的末端之下凹槽了分段的出發第二個鱗片列, 部分重疊的一個鱗片。 總計的側面鱗片 32; 橫跨的鱗片 1/4. Vertebrae 10+22. 顎骨孔 2+1/2+2. 頭部 3.2-3.5, 體高 5.1-5.3 分之一標準體長; 眼 3.1-3.7 分之一頭長; 顎骨 2.6-2.9 分之一頭長。 小魚, 少於 20 mm SL 。 身體細長的; 鱗片大的; 後頸覆有鱗片的; 腹面有比較小的, 細的圓形鱗片。 腹鰭細長的, 鰭條為較短的鰭條的大約三分之一長度藉著一個細又纖細薄膜聯合了。 第一背鰭些微地比第二個更高, 第二個 75-90% 的體高。 長的胸鰭鰭條幾乎對第三個背鰭的第一鰭條的基底達到。 上顳骨知覺的
管新月形的。 嘴斜角, 達到垂直的經過瞳孔的前緣; 眼間骨凹曲與寬的, 大約等於瞳孔直徑; 眼窩的卷鬚一個單一的圓蓋大約一半的瞳孔直徑長.(參考文獻 57774)
Collected from a flat reef (Ref. 57774). 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).
