A review of Problepsis Lederer, 1853 (Lepidoptera: Geometridae) from China, with description of two new species

摘要

The Chinese species of the genus Problepsis Lederer, 1853 are reviewed: 18 species are reported from China. Two new species, P stueningi sp. nov. and P batangnensis sp. nov. are described. One new combination is established: Problepsis transvehens (Prout, 1918) comb. nov. Two new synonyms are established: P. conjunctiva conjunctiva Warren, 1893 (= P conjunctiva subjunctiva Prout, 1917 syn. n.), Problepsis discophora Fixsen, 1887 (= P. changmei Yang, 1978 syn. n.). Two species, P plagiata (Butler, 1881) and P apollinaria (Guenee, 1858), and one subspecies, P discophora kardakoffi Prout, 1938, are newly recorded for China. Diagnoses for all discussed Chinese species are provided. External features and genitalia are depicted.
