Generic diagnosis.
In apterae, body round, flat, and strongly sclerotized. Prosoma consisting of fused head, thorax, and abdominal segment I; abdominal segments
II-VII
fused and distinctly separated from prosoma; abdominal segment VIII free. Dorsum of prosoma with scattered oval or irregular-shaped pustules and numerous fine setae; abdominal tergites
II-VII
with scattered shorter setae; each tergite with a pair of submarginal setae, setae on tergites V and VI shorter than setae on the other tergites; tergites II and VII each with a pair of spinal setae; abdominal tergite VIII with 4-8 setae. Eyes with 3 facets in apterae and compound in alatae. Antennae in apterae indis
tinctly
3-segmented, with primary rhinaria placed wide apart on the terminal segment, in alatae 5-segmented with annular secondary rhinaria. Rostrum short and thick. Ultimate rostral segment blunt wedge-shaped, with 2 pairs of primary setae and a pair of secondary setae. Legs normal, tibial setae long and fine, hind tibiae with several short peg-like setae on distal part; tarsi 2-segmented, claws normal, first tarsal chaetotaxy in apterae: 2, 2, 2. Abdomen with many long dorsal setae and 4 pairs of spiracles in alatae. Siphunculi in apterae small, pore-like, in alatae low but much expanded basally, with distinct minute papillae around the pore. Cauda knobbed and constricted at base. Anal plate bilobed. Wings dusky and reticulated; fore wings with pterostigma dark and broadly rounded at hind margin, media once branched; hind wings with 2 obliques.

Comments.
This genus is related to
Nipponaphis
Pergande, sharing several characters such as body of apterae aleyrodiform, flattened dorsoventrally, consisting of three parts - prosoma, fused abdominal segments
II-VII
, and separate abdominal segment VIII; dorsum of prosoma with scattered pustules; abdominal tergites
II-VII
with 6 pairs of submarginal setae and a pair of posteromesial setae on abdominal tergite VII; siphunculi pore-like; tarsi normal, 2-segmented, with normal claws; abdomen of alatae with 4 pairs of spiracles, and median vein of fore wings once branched.
Neonipponaphis
is distinguished by abdominal tergites
II-VII
distinctly separated from prosoma and the presence of numerous fine setae on the dorsum of prosoma and abdominal tergites II-VII in apterae.
