Discussion
Remarks This species can be distinguished from other known Saigona species by its cephalic process being bulbous apically, with 3 pairs of knoblike protuberance on lateral region; and male pygofer with a sharp, dorsoposteriorly directed process on the posterior margin near the apex. Based on dictyopharid material deposited in the Musée Heude, Shanghai, China, Lallemand (1942) described Piela singularis from Mt. Tianmu in Zhejiang Province in southeastern China; however, he did not provide any information about the type specimens he studied, including the number and sex of the type specimens. This species was neglected by Metcalf and it was not included in Metcalf’s (1942) catalogue of the world Dictyopharidae. Most specimens of Musée Heude, Shanghai, are now housed in the IZCAS, Beijing, China. In the IZCAS, we found one female specimen bearing a type label and a determination label with the name P. singularis Lallemand in Lallemand’s handwriting. We believe that the female specimen is the holotype of Piela singularis that Lallemand (1942) studied, because morphologically it matches Lallemand’s (1942) original description very well. Our careful examination of the female holotype shows that it is a synonym of S. fulgoroides (Walker, 1858).
Distribution
Distribution China (Fujian, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangxi, Sichuan, Taiwan, Zhejiang), Sumatra, Borneo. It is necessary to note that Walker (1858) reported fulgoroides from “n. China ” and he frequently referred to “North China ” in his publications on Chinese Homoptera (e.g. Walker, 1858: 67, 171). However, the ‘North China ” sensu Walker is actually southern China.
