Remarks

• Systematics: P. xanthorrhoeae as understood in Takagi, 2016, does not agree at least in three points with the concept of Poliaspis presented Hardy and Henderson (2011). First, this species has no extra abdominal disc pores, whereas all the species examined by them are provided with extra 'perivulvar' disc pores. Secondly, this species has the median trullae apparetnly not confluent basally, whereas according to them, the members of the genus except P. ceraflora have 'zygotic' median trullae. Thirdly, this species possesses a pair of small slender spinous processes on the mesal bases of the median trullae, whereas the presence of such processes is not clearly mentioned in all the species examined by them. However, Takagi concludes that these differences do not exclude this species from Poliaspis.
• Structure: Female scale shiny, white, pyriform, exuviae light yellow. Adult female yellow. Male puparium elongate, convex sides parallel, not carinated. Last segment of female depressed along the median (Fuller, 1899b).
• Biology: Its biology is unknown but all developmental stages were observed in Britain during May, and it may therefore have overlapping generations, and breed continuously if conditions allow. (Malumphy & Halstead, 2012)
• General Remarks: The original description is almost limited to the pygidium and especially to the marginal features on the sixth and succeeding abdominal segments. (Takagi, 2016) The type series is presumed to have been lost (Miller and Gimpel, 2009).
