Diagnosis

Neosistens rather similar to those of A. pectinatae   (see above), but wax ribbons thinner and more strongly curled, and spinal and pleural sclerites on mesothorax, metathorax and abdominal tergites 1–5 separate (although sometimes touching). Older sistentes and progredientes dark grey, embedded in fine, curly wax wool. Wax pore plates on inner margins of meso- and metathoracic spinal sclerites containing numerous small, mostly rounded, pits arranged in 2–4 areas of rather rounded shape, the most central area containing 7–12 pits. Found on bark, usually on young branches and twigs, single specimens occasionally on needles (my own record). Not ant-attended.
