Two new species of a new genus, Tortomon puer n. gen. n. sp. and T. gejiu
n. gen. n. sp. are described from southern Yunnan, southwestern China,
based on the morphology and mitochondrial 16S rDNA sequences. The new
genus resembles Tenuipotamon Dai, 1990 and Parvuspotamon Dai & Bo, 1994, but can be separated by characters of the male thoracic sternum, male pleon, male first gonopod, and
especially the coiled tip of the male second gonopod. The latter character easily separates Tortomon n. gen. from known potamid genera. Notes on the general biology of the two new species are also included.
