The present paper deals with the Chinese genus Neophyllaphis Takahashi, 1920, which includes 2 species, one of them, Neophyllaphis nigrubrunnea is new to science. The key to the Chinese species of this genus is given. The specimens including the types are deposited in the Institute of Zoology, Academia Sinica, Beijing. Key to the Chinese Species of Neophy llaphis Takahashi (Alate viviparous female)1. Third antennal segment shorter than fore tibia, with 12-15 secondary sensoriaNeophyllaphis nigrobrunnea, sp. nov.Third antennal segment equal to fore tibia, with 30- 45 secondary sensoriaNeophyllaphis podacarpi Takahashi1. Neophyllaphis nigrobrunnea Zhang et Zhang, sp. nov. (Fig.1)Alate viviparous female: dark brown in life. In mounted specimen pale. 1st and 2nd antennal segments brown, dorsum of head pale brown, mesonotum brown, marginal sclerites present on abdominal tergites 1 - 7, 8th tergite with pale tranverse band, cornicles pale brown. Veins of fore wings clear. Dorsal hairs of body short, 0.005-0.010 mm. 3rd antennal segment with 1 4-16 secondary sensoria. Rostrum reaching midcoxae, ultimate rostral segment without accessory hairs. Cauda constricted at base, elongate, bearing 16 hairs. Anal plates bilobed, bearing 8-14 hairs. 4 rudimentary gonaphyses, each with 2 hairs.Measurements in mm: length of body 1.459, width 0.61 4 ;antennae 0.838, segments I - VI : 0.004, 0.044, 0.321, 0.120, 0.122, 0.124+0.063;.ultimate rostral segment 0.067; cornicles 0.021 ; cauda 0.118; hind femur 0.273, hind tibia 0.533, 2nd hind tarsal joint 0.067.Holotype: alate viviparous female, No. 7860- 1 - 1 - 4, G uangdong Province: Ledong County, 26- Ⅲ -1984, Zhong Tiesen. Paratypes: 3 alate viviparous females, the others same as above.Based on 3rd antennal segment 0.75 times as long as segments (IV+ V + VI )and secondary sensoria on 3rd segment, this species is sibling to N. araucariae, but cornicles brown (pale in latter); differs from N. totarae Cottier in arrangement of secondary sensoria on 3rd segment.Based on dorsal hairs of short, it is related to N. brimblecombei Carver, 1971, but 3rd segment 2.7 times as long as 4th one (2.9- 3.3) , 1.9 times as 6th one (3.3-3.9), 0.75 times as long as segments (IV+V+VI ) (1.06-1.17); 14-16 secondary sensoria on 3rd segment (39-58 in the latter).
