Abstract
The genus Rhopalovalva Kuznetzov, 1964 belongs to Eucosmini within the famlily Tortricidae with larvae feeding on the plants of Fagaceae, Leguminosae, Convolvulaceae and Aceraceae. In this paper, Rhopalovalva is revised from China, with two species (Rhopalovalvaspinata sp. nov. and Rhopalovalva stilliformis sp. nov.) described as new to science. Photographs of the adults and male genitalia of these two new species are given. A key to Chinese species of Rhopalovalva Kuznetzov is provided based on the characters of the male genitalia.

Tortricidae is one of the largest Microlepidopteran families, with 11,365 described species worldwide [1]
Rhopalovalva Kuznetzov, 1964 belongs to the tribe Eucosmini within the family Tortricidae, which was erected with Eudemis lascivana Christoph, 1882 as the type species [4]

Summary
Tortricidae is one of the largest Microlepidopteran families, with 11,365 described species worldwide [1]. A division into three subfamilies, Tortricinae, Chlidanotinae and Olethreutinae, has been generally accepted, though only the latter two are natural groups defined by reliable characters [2]. The majority of tortricid caterpillars are leafrollers, but internal feeding is found in all subfamilies. Rhopalovalva Kuznetzov, 1964 belongs to the tribe Eucosmini within the family Tortricidae, which was erected with Eudemis lascivana Christoph, 1882 as the type species [4]. The host plants of Rhopalovalva spp. have been little known except four species: Rhopalovalva lascivana (Christoph, 1882) feeding on Quercus mongolica Fisch. Ex Ledeb., 1850 (Fagaceae), Rhopalovalva pulchra (Butler, 1879) on Q. sp. The host plants of Rhopalovalva spp. have been little known except four species: Rhopalovalva lascivana (Christoph, 1882) feeding on Quercus mongolica Fisch. ex Ledeb., 1850 (Fagaceae), Rhopalovalva pulchra (Butler, 1879) on Q. sp. (Fagaceae) [5,6,7], Rhopalovalva grapholitana (Caradja, 1916) on Lespedeza bicolor Turcz., 1840 (Leguminosae) [8] and Ipomoea aquatica
