Remarks

• Systematics: S. intermedia is closest to S. phyllocladi, sharing slightly developed abdominal lobes, and a group of duct tubercles near each anterior spiracle, but differs in usually lacking dorsal ducts on pygidium VII, in possessing more numerous microducts, especially between the medial lobes, and its host preference for Kunzea ericoides. MacGillivray (1921) in the key to his genus Scrupulaspis on page 274 erroneously characterised Mytilaspis intermedia Maskell under "Pygidium of adult female always without plates in median incisura." By plates he meant gland spines. Because Mytilaspis intermedia does have gland spines in the medial space (although not always extending much beyond the margin on slide-mounted specimens), the conclusion here is to ignore MacGillivray’s combination of Scrupulaspis intermedia. (Hendernson, 2011)
• Structure: "Female puparium yellowish-brown, the posterior end usually exhibiting a narrow border of white. Being placed transversely on small twigs of the plant, and coiling round them, it frequently appears very convex, the two ends meeting: the proper shape would probably be flat and pyriform." ... and ... "Male puparium of similar colour to that of the female, elongated, without carinations. It also is placed on small twigs, but longitudinally so that the form is not affected:it usually is placed amongst loose bud scales which it much resembles in colour and size." (Maskell, 1891).
