Takecallis Matsumura - Cottier, 1953: 87; Hille Ris Lambers, 1965: 202; Eastop, 1966: 519; Higuchi, 1968: 25; 1972: 35; Stroyan, 1977: 71; Ghosh, 1990: 229; Tao, 1990: 134.

Type species. – Callipterus arundicolens Clarke, 1903 , by original designation.

Diagnosis. – All viviparae alatae. Head with poorly developed antennal tubercles; dorsum without any sutures; clypeus with an anteriorly directed nose-like projection with 2 hairs. Antenna 6-segmented, shorter or longer than body; processus terminalis sub-equal to the base of the segment. Rostrum hardly reaching beyond fore coxae, ultimate rostral segment very short, shorter than second hind tarsal segment, with or without accessory hairs. Abdominal tergites pale, with small wart-like paired spinal elevations, sometimes on scleroites; spinal and marginal hairs on abdominal tergites single, spinal hairs on tergite VII laterally displaced, tergite VIII with 2- 5 dorsal hairs. All dorsal hairs of body short and acute. Siphunculi short, truncate, without distinct apical flange, with or without a hair appended to the base. Cauda knobbed, with 10-16 hairs. Anal plate bilobed. Rudimentary gonapophyses two. First tarsal segments each with 5 or 6 ventral hairs and 2 dorsal hairs. Empodial hairs flattened. Wax plates minute or absent. Fore wings with media twice-branched, hind wings with both obliques.

Embryos with long capitate dorsal hairs; spinal and marginal hairs single, pleural hairs absent. Siphunculi appear ring like.

Biology. – The members of this genus are pale yellow to pale green in life and infest leaves of bamboo ( Arundinaria , Phyllostachys , Pleioblastus , Sasaella , Sasa spp.). Only alate viviparae are known, sexual forms not known. These species appear to lead anholocyclic life cycles throughout the year ( Ghosh, 1990).

Distribution. – East Asia ( China, Japan, Korea, India), Europe, North America, and New Zealand.
