<p>An unusual yellow-striped deepwater hemerocoetine fish trawled up from 70 m depth in the Lakshadweep Sea (Laccadive Sea) off Kerala, southern India is described here as the new species <em>Pteropsaron indicum</em>, based on two male specimens measuring 82 and 84 mm SL. The new species of signalfish is notable among the grouping of three genera sharing crowded dorsal-fin spines and a maxillary spine (<em>Acanthaphritis</em>, <em>Osopsaron</em>, and <em>Pteropsaron</em>) in having only three dorsal-fin spines, greatly extended dorsal-fin soft rays in addition to the greatly extended dorsal-fin spines, high counts of rays in the dorsal and anal fins (D- III,27 and A- 29), a high number of vertebrae (38), and a large body size. <em>Pteropsaron indicum</em> possesses the distinctive arrangement of the spinous-dorsal-fin-pterygiophore complex found in this subset of trichonotid fishes. In <em>P. indicum</em>, the complex is placed between the fourth and fifth neural spines. The micro-computed tomography technique (micro-CT) is used to illustrate that osteological peculiarity in fine detail.</p>
