Lanternflies (Hemiptera: Fulgoridae) of Taiwan.

The family Fulgoridae belongs to the order Hemiptera, superfamily Fulgoridea, with approximately 770 described species worldwide. Their extraordinary appearance attracts the attention of both entomologists and the public. In addition to the evolutionary issue of their special appearance, certain species are also considered notorious pests (e.g., Lycorma delicatula). Several issues widely exist in previous taxonomic studies of lanternflies: (1) application of uncertain morphological characters leads to synonymy or misidentification; (2) descriptions of male genitalia are incomplete; (3) information of nymphal morphology is insufficient. Therefore, this study aims to provide a comprehensive taxonomic study of Fulgoridae from Taiwan. In this study, eight species in six genera from Taiwan were reported, of which Limois westwoodii was recorded for the first time from Taiwan. Lycorma olivacea was proposed as a new junior synonym of L. meliae. The fifth-instar nymph of Saiva formosana was described for the first time. Detailed descriptions of these lanternflies and an identification key to adults of Fulgoridae from Taiwan were also included.
