Abstract

A 2015 trawl survey along the coast of Myanmar provided an opportunity to assess species of the triglid genus Lepidotrigla occurring in the country. Three species, L. longipinnis Alcock, 1890, L. omanensis Regan, 1905, and an undescribed species, were identified among the 15 voucher specimens retained. A formal description of the unnamed species, as well as descriptive accounts of the other two are provided. Lepidotrigla psolokerkos, new species, based on two specimens, resembles L. alcocki Regan, 1908 described from the Saya de Malho Bank in the central Indian Ocean, differing from it in having fewer oblique scale rows between the anal fin origin and the lateral line and broader covering of dark pigmentation on the inner surface of the pectoral fin. The known geographical ranges of L. longipinnis, reported in the literature as L. riggsi Richards & Saksena, 1977, and L. omanensis are extended to the Andaman Sea off south-eastern Myanmar. A key is provided for the three species occurring in the survey area.
