Fig. 116

Diagnosis

Similar to C. juniperi and sometimes difficult to distinguish. Aptera 2.7–3.2 mm. C. mordvilkoi is slightly larger and its wax dusting is thinner and more evenly distributed, posterior part of abdomen often more or less shiny. Colour in both adults and juveniles – at least in Finnish material – greyish olive without reddish tinge. Spinopleural sclerites present on thorax but absent or strongly reduced on abdomen.

Durak (2011) made a DNA study combined with morphological analyses of the two species, confirmed their distinctness, and found some statistically significant distinguishing characters (all apparently related to size): see Table 1 .

Holocyclic, monoecious on Juniperus communis . In spring on thin twigs, in summer moving to roots and stems at ground level. Recorded hosts
