Identification & Distribution

Adult apterae of Cinara pinihabitans (see pictures below of oviparae) have the abdomen wax powdered. On the dorsum there is a transverse dull brown to black marking between the siphuncular cones, sometimes extending forwards along the spinal and pleural areas, and a broken cross bar on tergite VIII. The apical segment(s) of the rostrum (RIV+V) is about 0.8 times as long as the second hind tarsal segment, and has 4-5 accessory hairs. Hairs on the appendages and body are denser and longer than in most pine-feeding Cinara species. Hence the longest hairs on antennal segment III of Cinara pinihabitans are 110-150 μm long (cf. Cinara nuda & Cinara pini, which both have longest hairs on antennal segment III at 25-10 μm). The longest hairs on the hind tibiae are 170-190 μm (cf. Cinara nuda & Cinara pini, which both have longest hairs on the hind tibiae at 40-130 μm). There are 40-50 hairs on the abdominal tergite between the siphuncular cones, with the longest 140-180 μm (cf. Cinara nuda & Cinara pini, which both have 3-44 hairs between the siphunculi, with the longest 5-140 μm). The siphuncular cones are rather low and inconspicuous (cf. Cinara pini, which has black and prominent siphuncular cones). The body length of Cinara pinihabitans adult aptera is 3.1-4.6 mm.

The alate Cinara pinihabitans has the posterior part of the body sometimes covered with white wax; more frequently with waxy transverse intersegmental stripes as on the anterior part of the body.

Cinara pinihabitans is monoecious on pine (Pinus species), especially Pinus sylvestris and Pinus mugo, forming colonies on old branches (see Stroyan, 1973). There is no host alternation. Sexuales occur in October, the oviparae having a very distinct pericaudal wax ring. The oviparae lays their eggs on the upper sides of the branches. The species is found over much of northern and eastern Europe and Asia.

We have made provisional identifications from high resolution photos of living specimens, along with host plant identity. In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens. We have used the keys and species accounts of Blackman & Eastop (1994) and Blackman & Eastop (2006) supplemented with Blackman (1974), Stroyan (1977), Stroyan (1984), Blackman & Eastop (1984), Heie (1980-1995), Dixon & Thieme (2007) and Blackman (2010). We fully acknowledge these authors as the source for the (summarized) taxonomic information we have presented. Any errors in identification or information are ours alone, and we would be very grateful for any corrections. For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006).
