Remarks

• Systematics: Green (1934) states that this species is "very similar, in general appearance, to Fiorinia pygosema, but differing in the presence of perivulvar pores and the smaller number of pygidial processes." According to Takagi (2002) the long processes of F. pygosema are gland spines or modified plates, whereas the long processes of M. quadrispinosa are probably modified lobes. He therefore did not agree with Green that the species are congeneric.
• Structure: Adult female scale cover long and narrow, covered with a greyish secretion; exuviae brown. Male scale cover white and narrow. Slide-mounted adult female elongate oval. Antennae each with 3−5 long setae. Anterior spiracles each associated with 2 disc pores and a cluster of 10−12 duct tubercles, situated laterally to spiracle. Posterior spiracles without associated disc pores or duct tubercles. Pygidium without lobes or plates, but with 4 long caudal processes, each slender and tapering; median processes each with 1 minute dorsal duct basally, and outer processes each with 2 such ducts. Pygidial dorsum with about 7 sclerotized patches. Dorsal and ventral ducts absent from pygidium and prepygidium. Perivulvar pores present in 5 groups.(Moghaddam & Watson, 2021)
