Remarks

• Systematics: Marsipococcus christopheri can be easily separated from M. marsupialis by (character states of M. marsupialis given in parenthesis): absence of ventral multilocular disc pores, dorsal propercular pores and ventral tubular ducts (all three characters present). It can be distinguished from M. ulubendulensis by (character states of M. ulubendulensis given in parenthesis): marginal setae spinose (lanceolate) and ventral tubular ducts absent (present). (Joshi, 2020) The first-instar nymph of M. christopheri sp. n. is similar to that of M. ulubendulensis but differs by its smaller body size, and in having (character states ofM. ulubendulensis given in parenthesis): a sclerotized spiracular cleft (unsclerotised); dorsal surface of anal plate with an interlocking sclerotized area, forming a zigzag pattern (zigzag pattern absent); size of anterior and posterior spiracular setae similar (seta sizes different); spiracular setae with rounded apices (truncate); and claw digitules similar to each other (claw digitules different from each other). (Joshi, 2020)
• Structure: Adult female mostly flat but slightly convex in median area; pear shaped with posterior half widest; extremities rounded. Median area reddish, mottled with dark purple brown, with four paired, irregular rectangular depressions, arranged in linear fashion on either side of mid-dorsal line. Median reddish area with a diffuse yellow border that merges into the transparent submarginal and marginal area. Fine, whitish marginal setae visible to the naked eye against dark green leaf; pale yellow spiracular furrows sharply distinct from the darker marginal area. Eyes minute, black, situated in dorsal submargin. Slide-mounted adult female (Fig. 2A). Body pear-shaped, broadest at abdomen, 4.6–4.9 mm long and 3.2–3.7 mm wide. Stigmatic clefts distinct and moderately deep; anal cleft closely appressed, about 1/6th to 1/9th of total body length. (Joshi, 2020)
