Biology. Living singly beneath leaf sheath, usually on twigs, sometimes on stem.
Remarks. Tang (1977) established a new genus Longicoccus with the type species Longicoccous elongatus. This was based on specimens collected from Hangzhou city, Zhejiang province but, although his syntypes can be recognised, no holotype was designated, and no date or collector was given. Kozár and Walter (1985) transferred L. elongatus to Tangicoccu s because Longicoccus was preoccupied by Longicoccus Danzig (1975), also in the family Pseudococcidae. Later, Tang (1992) designated slide-mounted specimens as lectotype and paralectotypes as follows: lectotype Ƥ, collected from Hangzhou city of Zhejiang province on Bambusa sp., 2 April 1969; paralectotypes: 3ƤƤ, same data as lectotype, although incorrectly labelled as holotype and paratypes. Tang (1992) also included two other samples, i.e., 1Ƥ, Shuze county of Fujian province on Bambusa sp., 9 Sept. 1977, and 1Ƥ, Jiansha county of Fujian province on Bambusa sp., 4 Sept. 1977 as paralectotypes, but this designation is erroneous according to the International Code of Zoological Nomenclature because those two samples were not mentioned in Tang’s (1977) original paper.
This species was described by Tang (1977) and redescribed by Tang (1992) and Hendricks and Kosztarab (1999). The differences between these description are: Tang (1977) described the anal ring as lacking pores but with 2 setae, and the posterior 4 abdominal segments as having multilocular disc pores ventrally; Tang (1992) stated that the anal ring had neither pores nor setae and that multilocular disc pore were entirely absent, whereas Hendricks and Kosztarab (1999) considered that the anal ring had pores and 6 short setae and that multilocular disc pores were entirely absent. We also found that the anal ring did have pores and 6 short setae and that there were no multilocular disc pores.
