Body dorsoventrally flattened, widest anterior to the siphunculi, evenly tapering towards head. Dorsal hairs on abdomen sparse and very short, mostly 0.01–0.04 mm , usually less than 10 hairs between the siphuncular sclerites. See also C. acutirostris (on Pinus nigra and P. pinea ) and C. cembrae (on P. cembra ). Ovipara (if correctly interpreted) with a large dull black transverse sclerite across segments 5 and 6, encompassing the siphunculi, but not extending forwards as in C. nigritergi . Holocyclic, monoecious on Pinus . Open forests, meadow margins, sea shores etc. Forming small colonies on young shoots, twigs and branches, viviparous colonies almost invariably attended by ants. Recorded hosts Pinaceae : Pinus mugo * , sylvestris *. Records from Pinus banksiana , cembra , contorta , nigra , pinaster , pinea , sibirica , strobus etc. are to be confirmed. According to Eastop (1972) and Blackman & Eastop (2015) , records from hosts other than P. sylvestris are likely to be misidentifications or misapplications of the name pini . Recorded attendant ants Formicinae : Camponotus herculeanus * ; Formica aquilonia * , cinerea * , fusca * , lemani * , polyctena * , pratensis * , rufa * , sanguinea * , truncorum * ; Lasius niger *.
