Revision of the Drabescus ineffectus species group with descriptions of five new species from southern China (Hemiptera, Cicadellidae, Deltocephalinae)
Year: 2026
Type: article
Abstract: Five new species of the leafhopper genus Drabescus (Hemiptera, Cicadellidae, Deltocephalinae) from southern China are described and illustrated: Drabescus denticulatus Qu, Li, Dietrich & Dai, D. digitulatus Qu, Li, Dietrich & Dai, D. guangdongensis Qu, Li, Dietrich & Dai, D. millesimus Li, Qu & Dai, and D. trigonius Qu, Li, Dietrich & Dai. These species are morphologically similar to Drabescus ineffectus (Walker, 1858) but can be distinguished by diagnostic differences in the male genitalia, particularly in the shape of the aedeagal shaft, processes, and associated structures. The D. ineffectus species group is established to accommodate these five new species and four other related species. Detailed descriptions, diagnoses, and illustrations are provided for all new taxa. An updated checklist and an identification key to males of the 41 known Chinese Drabescus species are also presented. Type specimens are deposited in the Institute of Entomology, Guizhou University (GUGC).
