Abstract. We report on the carnivorous rathouisiid slugs in Myanmar, including one new record, Atopos laidlawi Collinge, 1902, from Tanintharyi Region, and describe one new species, Atopos transversus, new species, from Shan State. Previously, only Atopos gravelyi Ghosh, 1915 from Kayin State had been documented from Myanmar. Detailed descriptions along with illustrations of the external morphology and genital characters are provided herein. Among the distinguishing features, A. transversus, new species, has a Simroth gland with the evaginable part slightly shorter than the penis length, a short-interconnected duct, and a cylindrical secretory part, whereas A. laidlawi possesses a Simroth gland in which the evaginable part is similar in length to the penis, has a long-interconnected duct, and a bulbous secretory part.
