Remarks

• Systematics: Slide-mounted adult female with: enlarged setae cylindrical, sides concave, apices rounded, marginal setae, medial and mediolateral line of setae on thorax and head conspicuously larger than other dorsal setae, 1 or 2 lateral setae on margin of each abdominal segment, bases of setae with several associated microtubular ducts; suranal setae spatulate; microtubular ducts elongate, without sclerotized area (Hoy, 1962). The adult females of M. maculatus are most similar to those of M. cruriamplus. Features shared between the two are: 1, macrotubular ducts absent; 2, enlarged dorsal setae few or absent; 3, distinct marginal fringe present, and 4, suranal setae approximately as long as anal lobes. The adult females of M. maculatus differ from those of M. cruriamplus by having numerous enlarged dorsal setae (all dorsal setae minute in M. cruriamplus).
• Structure: Insect occurs on the under side of host leaves. Female does not form a sac. Body is green and segmentation is indicated by color patterns (Hoy, 1962).
• General Remarks: Detailed description and illustration by Hoy (1962).
