• WilliaWa1988: pp.80 ( ) [Key to species of Chionaspis of the Tropical South Pacific Region] Key as: Chionaspis rhaphidophorae

Remarks

• Systematics: When compared with the species from the South Pacific area, the species known as Chionaspis rhaphidophorae has a superficial resemblance to two turbinate species of Pseudaulacaspis. It does not possess setae between the median lobes, however, and is therefore excluded from Pseudaulacaspis. Among the Holarctic species of Chionaspis that have median lobes almost fused throughout their length, or close together are C. lumbiniana, C. caryae and C. ortholobis, but these species are fusiform, whereas C. rhaphidophorae is broadly oval or even turbinate. The extremely slender thoracic gland spines, which are sclerotized and blunt, are characters that separate this species from any other in the Pacific area (Williams & Watson, 1988). Serenaspis rhaphidophorae (Williams & Watson) is very close to S. minima (Maskell), currently only known from New Zealand, sharing the presence of: (i) duct tubercles as far forward as at least the mesothorax, (ii) spiracular disc-pores associated with both anterior and posterior spiracles. and (iii) median lobes close together, with inner margins more or less parallel along most of their length and lacking a strong yoke linking the lobes together. On this basis, C. rhaphidophorae was transferred to Serenaspis.by Lagowska & Hodgson, 2012.
• General Remarks: Best description and illustration by Williams & Watson (1988).
