Idiococcus maanshanensis Tang & Wu, in Tang, 1984: 101; 1984a: 395; 1992: 36; Wang, 2001: 43 (synonymy by Hendricks & Kosztarab, 1999)

Distribution in China. Anhui, Zhejiang.

Host plants. Pleioblastus amarus, Indocalamus migoi .

Material examined: 19ƤƤ, ANHUI: Maanshan city, on Indocalamus migoi, 18 Aug. 1979, Coll. Shi-jun Wu; 3ƤƤ, ANHUI: Maanshan city, on Indocalamus migoi, 9 Feb. 1981, Coll. Shi-jun Wu; 6ƤƤ, ANHUI: Maanshan city, on Indocalamus migoi, 24 Feb. 1983, Coll. Shi-jun Wu; 4 ƤƤ, ZHEJIANG: Mt. Tianmushan, on Indocalamus migoi, 12 Apr. 1999, Coll. San-an Wu; 1Ƥ, ZHEJIANG: Lin’an city, on Pleioblastus amarus, 18 Apr. 1999, Coll. San-an Wu.

Biology. Living in groups on stem of the host beneath leaf sheath.

Remarks. The location of the mouthparts varies among specimens, but is usually present on the mesothoracic sternite between anterior and posterior spiracles. Tang (1984, 1984a) described the anal ring as having pores but no setae, but we found 6 short anal ring setae in teneral females. Hendricks and Kosztarab (1999) mostly examined specimens from Japan (the lectotype is from Japan) and described multilocular disc pores on the abdominal venter, but we could not find them on any of the examined Chinese specimens, even when the body was unsclerotized. Perhaps Idiococcus maanshanensis should be considered to be a valid species, not a synonym of I. bambusae as suggested by Hendricks and Kosztarab (1999).
