Contribution to the Knowledge of the Genus Linda Thomson, 1864 (Part I), with the Description of Linda (Linda) subatricornis n. sp. from China (Coleoptera, Cerambycidae, Lamiinae)
Linda (Linda) subatricornis n. sp is described from Sichuan (holotype locality), Fujian, Shaanxi, Hebei, Ningxia of China. It is separated from the most similar species L. atricornis Pic by differences in genitalia and antennal insertions. Detailed descriptions, photographs of habitus and genitalia, distribution of the two sibling species and short discussion on the related species are presented. 1. Introduction Linda Thomson, 1864 [1], includes two subgenera, Linda and Dasylinda, mostly confined to China [2]. While studying more than 150 specimens of Linda (Linda) atricornis Pic from different localities, we were surprised to observe two very different kinds of male genitalia. We concluded that two superficially similar species have been historically misidentified as one species. We had examined the types of L. atricornis, L. gracilicornis, L. major (the three known species of subgenus Linda with elytra and antennae all black), and most of the other species of this genus. After careful observation and dissection, we separate L. subatricornis n. sp. and herein describe it as new to science. 2. Materials and Methods Types and other material studied are deposited in the following institutions or private collections.CCH: Collection of Dr. Carolus Holzschuh, Villach, Austria.CPS: Collection of Dr. Carlo Pesarini and Dr. Andrea Sabbadini, Milano, Italy.HBU: Museum of Hebei University, Hebei, China.IRSNB: Institut royal des Sciences naturelles de Belgique, Bruxelles, Belgique.IZAS: Institute of Zoology, Chinese Academy of Sciences, Beijing, China.MHNG: Muséum d’Histoire Naturelle de Genève, Switzerland.MNHN: Muséum National d’Histoire Naturelle, Paris, France.SYSU: Sun-Yatsen University, Guangzhou, China. 3.
