Many of these also occur on other bamboo genera, and the large number recorded from Bambusa may simply be because it is the best known genus. The key is an updated and expanded version of that provided by Blackman & Eastop (1984). It includes species recorded from unidentified bamboos, possibly not of this genus. The Hormaphidinae associated with bamboos are in need of further study to determine their life cycles and clarify taxonomic relationships, and reliable identification of Astegopteryx and Ceratovacuna to species is not usually possible in the present state of knowledge. Aoki et al. (2007) provide a key to bamboo-feeding Pseudoregma. Bambusa arundinacea = B. bambos
