Diagnosis

Neosistens 0.3–0.4 mm, shiny black with a double spinal crest and a marginal rim of more or less curly wax ribbons, and a posterior tuft of wax wool. Older sistentes and progredientes dark grey, embedded in a tuft of thick, stiff, ‘half-pipe’ shaped wax filaments. Spinal and pleural sclerites fused on all segments, and spinopleural sclerites also fused to marginal sclerites of abdominal tergites 6–8. Older sistentes and progredientes dark grey to purplish grey, richly exuding thick, curly wax filaments. Holocyclic and dioecious, alternating between spruce ( Picea   , p. 8) and fir ( Abies   ). Predominantly in parks and plantations, scattered on needles, both upper- and undersides, often in great number. Not ant-attended. Apparently predominantly anholocyclic on Abies   . Not ant-attended.
