  Laing (1929) was hesitant to describe this as a new species because it was so close to Chionaspis striata. Adult females of P. callitris can be distinguished from other species of Poliaspis on the basis of (1) setae between median lobes absent (also absent in P. araucariae and P. nitens); and (2) the relatively large number of pores near anterior spiracle (9-15) and no pores near posterior spiracle (other species of Poliaspis having many pores near anterior spiracle have at least a few near posterior spiracle). It shares having only 1 small gland spine on the margin of abdominal segments 6 and 7 with P. ceraflora, but that species has non-zygotic median lobes. (Hardy & Henderson, 2011)

• Structure: Adult female snowy white, exuviae very pale stramineous, 2.2 mm long (Laing, 1929). Slide-mounted adult female body outline fusiform, without distinct thoracic and abdominal lobes. Pygidium with 2 pairs of lobes; median lobes zygotic, much smaller than medial lobule of second lobe, each lobe with pointed apex; margin between median lobes not incised; second lobe bi-lobed, lateral lobule minute in some specimens (including holotype), medial lobule with strong basal sclerosis. (Hardy & Henderson, 2011)
