Two new species of Trimma are described from Fiji. Trimma bathum n. sp. lacks scales on the cheeks, opercle and predorsal midline, has 18-19 unbranched pectoral fin rays, an unbranched 5th pelvic fin ray that is 40-56% the length of the 4th ray, 17-18 gill rakers on the outer surface of the first gill arch, a U-shaped interorbital and a narrow slit-like postorbital trench, a low, median fleshy ridge extending half-way towards the orbit from the origin of the first dorsal fin, and, when freshly collected, a pink head and body with most body scales having an orange-brown spot or short bar at their centres. The species is currently known only from off Suva Harbour, Viti Levu, Fiji. Trimma finistrinum n. sp. has a bony interorbital equal to the pupil diameter, a fully scaled nape of 12-14 scales, a second dorsal spine that may reach posteriorly to the middle of the second dorsal fin, the papillae in the longitudinal row immediately below the eye either single or with two papillae in a vertical row, unbranched pectoral fin rays, usually a branched fifth pelvic-fin ray that is about half length of the fourth ray, and a large diffuse dark blotch on the posterior part of the caudal peduncle. A colour pattern of a brownish body with most body scales having golden- to greenish-yellow (pale in preservative) centres is unique among species of the genus. The species is currently recorded only from off the north and east coasts of Viti Levu, Fiji.
斐济发现了两种新的微天竺鲷属鱼类。巴氏微天竺鲷新种脸颊、鳃盖和背鳍前中线无鳞，胸鳍有18 - 19根不分枝鳍条，第五根腹鳍不分枝鳍条长度为第四根的40 - 56%，第一鳃弓外表面有17 - 18个鳃耙，眶间呈U形，眶后沟窄且呈裂缝状，从第一背鳍起点向眼眶延伸一半距离处有一条低的、位于中线的肉质嵴，刚采集时头部和身体呈粉红色，大多数体鳞中央有一个橙褐色斑点或短条纹。该物种目前仅在斐济维提岛苏瓦港外被发现。细条纹微天竺鲷新种的眶间骨宽度等于瞳孔直径，颈背完全被鳞，有12 - 14枚鳞片，第二背棘后端可能延伸至第二背鳍中部，眼下纵列的乳突单个或垂直排列有两个乳突，胸鳍不分枝鳍条，第五根腹鳍通常分枝，长度约为第四根的一半，尾柄后部有一个大的弥散性黑斑。身体呈褐色，大多数体鳞中央为金黄至绿黄色（保存后变浅）的体色模式在该属物种中独一无二。该物种目前仅记录于斐济维提岛的北海岸和东海岸外。
