Holotype: apterous viviparous female, CHINA: Tibet (Yadong County, Xiayadong Town), 25.vi.2016, No. 37412-1-6-2, on Acer palmatum Thunb., coll. FF Niu (NZMC). Paratypes: 7 apterous viviparous females, 1 alate viviparous female, 1 fourth instar nymph and 1 young nymph (first or second instar nymph, with the same collection data as holotype (NZMC); 2 apterous viviparous females, No. 37412-1-4, with the same collection data as holotype (NHM).</p> <p>Distribution. China (Tibet).</p> <p>Host plant. Acer palmatum Thunb.</p> <p>Biology. The aphids were found feeding in small numbers on the basal parts of the samaras of Acer palmatum Thunb. But, the life-cycle is unknown (Figs 46–51).</p> <p>Comments. The new genus is unique in Chaitophorini by having apterae with a conspicuous median dorsal ridge, by the wart-like sculpturing of the entire dorsal cuticle, and by the siphunculi with spinulose striae. The apterae share several characters with Trichaitophorus and Yamatochaitophorus, such as head and prothorax fused, eyes with approx. 25 facets or less, abdominal tergites I-VII completely fused, inner and outer setae on distal half of tibiae distinctly differentiated, flattened empodial setae, siphunculi short and truncated, and anal plate entire and broadly rounded. However, the new genus differs from them as follows: except for the long frontal setae and dorsal setae on abdominal tergites VII-VIII, the dorsal setae of Glyphochaitophorus are hardly discernible, whereas in Trichaitophorus there are short and long, thick or dilated marginal setae at least on the thorax and abdominal tergites I-VI, and Yamatochaitophorus has long thick spinal, pleural and marginal setae with knobbed or blunt apices on all body segments. Tibial setae of Glyphochaitophorus are mainly distributed over distal two-thirds of tibia, and show considerable differences in size and form, with the most distal setae longest, and the outer setae expanded apically and arising from basal tubercles. In Trichaitophorus and Yamatochaitophorus setae are distributed over the whole length of the tibiae, all the outer setae being long thick and pointed. Other differences are the siphunculi with spinulose striae (in Trichaitophorus they are corrugated or striate but without any spinules, and in Yamatochaitophorus they have only with weak transverse imbrications); the distinctly knobbed cauda (in the other two genera the cauda is rounded).</p> <p>Besides the new genus, there are three other genera of Chaitophorini associated with Acer; Periphyllus, Trichaitophorus and Yamatochaitophorus. These four genera are differentiated by the key that follows:</p> </div>	http://treatment.plazi.org/id/474B87E2FFBBE72CA1E2E87954C8F8C4	Public Domain	No known copyright restrictions apply.
