description: Key to Hybothoracaphis gen. nov. and allied genera (based on apterous viviparous females)
1. Antennae small, unsegmented; body with a conspicuous median dorsal ridge; central axis of dorsal prosoma with clusters of irregular-shaped pustules, located before and behind the muscle attachment plates; on Quercus (Fagaceae); China ......................................................................................... Hybothoracaphis gen. nov.
- Antennae 3- or 4-segmented; body without a conspicuous median dorsal ridge; central axis of dorsal prosoma without pustule clusters.............................................................................................. 2
2. Dorsum of prosoma divided by sutures into a large median and two lateral areas; on Lauraceae and Senecio (Compositae); China, India, Indonesia, Japan, North America. ..................................... Euthoracaphis Takahashi, 1938
- Dorsum of prosoma never divided into regions.............................................................. 3
3. Abdominal tergite VIII always with 2 setae, rarely with 4 setae; densely scattered pustules on prosoma appear double rimmed; on Distylium (Hamamelidaceae) and Fagaceae; China, India, Indonesia, Japan .......... Metanipponaphis Takahashi, 1959
- Abdominal tergite VIII usually with 4–8 setae, if sometimes with 2 setae then pustules never double rimmed.............4
4. Dorsal setae on prosoma long, rather thick and stout, arising from conspicuous bases, sometimes mixed with smaller and finer setae; on Distylium (Hamamelidaceae), Lauraceae, and Fagaceae; China, India, Indonesia, Japan, Malaysia, Nepal, Thailand ......................................................................... Schizoneuraphis van der Goot, 1917
- Dorsal setae on prosoma fine, if thick then never as above..................................................... 5
5. Prosoma completely separated from abdominal segments II–VII; dorsum of prosoma with numerous fine setae; on Castanopsis (Fagaceae); China, Japan ................................................... Neonipponaphis Takahashi, 1962
- Prosoma distinctly or indistinctly separated from abdominal segments II–VII; dorsum of prosoma not bearing so many setae as above............................................................................................... 6
6. Dorsum of prosoma almost smooth, variably corrugated, or covered with pustules; margin of prosoma sometimes radially striped, palisade-like, or with a polygonal reticulated band; abdominal tergite VIII with 2–4 setae; on Quercus (Fagaceae) and Lindera (Lauraceae); China, India, Indonesia, Japan, Malaysia, Thailand, Turkey .......... Thoracaphis van der Goot, 1917
- Dorsum of prosoma densely covered with pustules; margin of prosoma never with a striped or polygonal reticulated band; abdominal tergite VIII with 4–8 setae; on Distylium (Hamamelidaceae), Fagaceae, Lauraceae, and Moraceae; China, India, Indonesia, Japan, Korea.......................................................... Nipponaphis Pergande, 1906
