This study provides new records of two genera in China, as well as the description of two new species. These findings are important for further biological and morphological studies, as well as molecular data support. Additionally, a new record of Melanotrichia attia is documented for the Chinese caddisfly fauna.
Simple Summary The small family Xiphocentronidae Ross 1949 (186 species and 7 genera) has a wide distribution and high diversity in the Oriental region. Despite the rich biodiversity of Trichoptera in eastern China, only one xiphocentronid genus (Melanotrichia), with three species, is recognized. The status of Xiphocentronidae as an evolutionary lineage distinct from Psychomyiidae has been subject to debate in the past. The specimens in this study provide additional records on the distribution of two genera in China, which are conducive to biological and morphological studies and can also provide molecular data support for further studies. The genera Abaria Mosely 1948 and Drepanocentron Schmid 1982 are recorded in China for the first time. In this study, two new species, Abaria herringbona sp. nov., from Guang-xi, and Drepanocentron fuxiensis sp. nov., from An-hui, are described and illustrated. Male genitalia of these two new species is distinguishable from those of other Abaria and Drepanocentron species. In addition, Melanotrichia attia Malicky & Chantaramongkol 1992 is a new record for the Chinese caddisfly fauna.
