The present paper is the 9th in series of cataloguing the aphids belonging to subfamily Hormaphidinae (Aphididae: Hemiptera). In preparing of this checklist, recent world literatures (published up to January, 2018) were scrutinised for synonymy of the aphid species as well as their host plants available at websites: http://Aphid.SpeciesFile.org (version 5.0/5.0) for aphids, and http://www.ars-grin.gov and http://www.theplantlist.org (version 1.1) for plants accessed on January, 2018. Hormaphidinae includes three tribes: Hormaphidini, Nipponaphidini and Cerataphidini. From India, total 57 species of Hormaphidinae were recorded under 23 genera, of which 35 species are endemic. Cerataphidini includes 34 aphid species that feed on 46 species of host plants belonging to 15 families. The host plant association demonstrated that out of 34 species of cerataphidini, 19 are monophagous and mostly feeding on bamboo; 11 are oligophagous (2-5 plant species) and only 4 species are polyphagous (6-7 plant species). Of 34 species, 23 feeds on bamboo or other grasses. Hormaphidini includes only 2 monophagous aphid species that feed on 3 species of host plants belonging to 2 families. Nipponaphidini includes 21 aphid species that feed on 17 species of host plants belonging to 9 families. Of 21 species of Nipponaphidini, 14 species are monophagous and mostly feeding on Fagaceae and the rest 7 species are oligophagous. Most of them feed on plants belonging to Fagaceae and Lauraceae.
