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.
