Remarks

• Systematics: Duplachionaspis monodi is close to D. noaeae, but differs in having the gland spines paired on segments VII and VIII, in the shape of the median lobes which are parallel sided. D. monodi also always has some smaller dorsal ducts submedially on segment VI which according to Balachowsky (1954e) are always absent on this segment in D. noaeae. D. monodi also resembles D. humilis but can be told by having paired gland spines on segments VII and VIII in the adult instar and in the absence of submarginal dorsocephalic ducts in the first instar. Finally, D. monodi is known exclusively from grasses while D. humilis is known exclusively from members of the Liliaceae (Munting, 1969).
• Structure: Female scale elongate, broadening posteriorly, about 3 mm long, white, pale yellow exuviae. Male puparium elongate, parallel-sided, with a median carina and pale yellow exuviae; about 1.2 mm long. Adult female fusiform, membranous, about 1.8 mm long. First instar exuviae with 5-segmented antennae, terminal segment non-annulate, submarginal dorsocephalic ducts absent (Munting, 1969).
• General Remarks: Detailed description and illustration by Munting (1969).
