Lepadichthys coccinotaenia Regan 1921 (Gobiesocidae: Diademichthyinae) is redescribed on the basis of 60 specimens, including the holotype, and a new species of Lepadichthys, previously misidentified as L. coccinotaenia, described from Japan. Lepadichthys trishula sp. nov. is characterized by the following combination of characters: 10–12 (modally 11) dorsal-fin rays; 9–11 (10) anal-fin rays; 23–26 (23) pectoral-fin rays; upper end of gill membrane level with base of 8th to 10th (usually 10th) pectoral-fin ray in lateral view; 6–8 (7) gill rakers on each arch; 32 or 33 (32) vertebrae; snout somewhat short and slender, its length and depth 7.4–9.4 (mean 8.4) and 4.0–6.5 (5.1) % SL, respectively; upper jaw not sharply pointed or projected, its length 5.5–7.7 (6.5) % SL; side of lower-jaw teeth with hook-like tips; head depth 7.2–10.4 (8.5) % SL; disc size moderate, its length 14.0–18.2 (16.8) % SL; dorsal and anal fins with weak membranous connections to caudal fin; head sensory canal pores well developed, including 2 nasal, lacrimal and postorbital, and 3 preopercular pores; and three narrow white stripes from snout to vertical through posterior margin of disc, including two lateral and one on the dorsal midline. The new species is currently known only from Japan, whereas L. coccinotaenia occurs only in the southwestern Indian Ocean.

Lepadichthys coccinotaenia Regan 1921（Gobiesocidae：Diademichthyinae）在 60 个标本的基础上重新描述，包括正模标本和 Lepadichthys 的一个新物种，以前被误认为是 L. coccinotaenia，来自日本。Lepadichthys trishula sp. 十一月 具有以下特征组合：10-12（模态11）背鳍条；9-11 (10) 条臀鳍鱼；23-26 (23) 条胸鳍条；鳃膜上端与第 8 至第 10（通常是第 10）胸鳍鳍条基部在侧视图上平；每个拱形上有 6-8 (7) 个鳃耙；32 或 33 (32) 节椎骨；吻有点短和细长，其长度和深度分别为 7.4-9.4（平均 8.4）和 4.0-6.5（5.1）% SL；上颌不尖锐或突出，其长度为 5.5–7.7 (6.5) % SL；具有钩状尖端的下颌牙齿的一侧；头部深度 7.2–10.4 (8.5) % SL；圆盘大小适中，其长度为 14.0–18.2 (16.8) % SL；背鳍和臀鳍与尾鳍的膜质连接较弱；头部感觉管孔发育良好，包括2个鼻、泪、眶后孔，3个前鳃盖孔；和从吻部到垂直穿过椎间盘后缘的三条窄的白色条纹，包括两条横向和一条在背中线。该新种目前仅在日本已知，而 L. coccinotaenia 仅出现在印度洋西南部。包括两个侧面和一个在背中线。该新种目前仅在日本已知，而 L. coccinotaenia 仅出现在印度洋西南部。包括两个侧面和一个在背中线。该新种目前仅在日本已知，而 L. coccinotaenia 仅出现在印度洋西南部。
