ABSTRACT. This contribution is devoted to descriptions of two new identifiable paradoxosomatid species from Nepal: Chondromorpha greke sp.n. and Delarthrum telnovi sp.n. This is the first formal record of the genus Chondromorpha Silvestri, 1897 from Nepal, although it is rather to be regarded as a tropical Indian faunal element, not a Himalayan one. A tabular key to all six presently known species of Chondromorpha is given. In contrast, Delarthrum telnovi sp.n. belongs to the Himalayan hingstoni-group of the very large genus Delarthrum Attems, 1936, all 55 species of which, mostly Himalayan, range from the Western Ghats in the south to the Himalayas of Pakistan, Nepal, China/Tibet, and India in the north. Even though Delarthrum telnovi sp.n. shows unexpectedly considerable variations, both morphological and geographic, it is considered as a single polymorphous species.
