Remarks

• Systematics: According to Hodgson, 2025a, all of the available material is in very poor condition but the species is recognizable by the following combination of character-states: (i) body broadly oval; (ii) anal plates together about as long as combined width; (iii) underside of each anal plate without a deep cleft on inner margin; (iv) margin not crenulated; (v) marginal and dorsal setae very similar in size; (vi) preopercular pores fairly easily distinguishable from dorsal simple pores; (vii) preopercular pores associated with CA1 very few or absent; (viii) each stigmatic cleft with 3 or 4 long, narrow stigmatic spines; (ix) each stigmatic cleft with 1‒3 marginal setae along outer margin; (x) multilocular disc-pores restricted to abdominal segments VI and VII; (xi) legs each reduced to just a claw or absent, and (xii) antennae very reduced, consisting of a narrow scape, with all other segments fused. P. cribrigerum is closest to P. citri, and P. faveolatum. Platylecanium cribrigerum differs from P. citri in having each anal plate 145‒185 μm long and 71‒85 μm wide, whereas each anal plate of P. citri is longer and narrower - about 230 μm long and 65 μm wide (Takahashi 1942). Platylecanium cribrigerum differs from P. faveolatum in having: (i) multilocular disc-pores each with 10 loculi (only 6 or 7 loculi in P. faveolatum) and (ii) few preopercular pores, mainly associated with the posteriormost pairs of clear areas, whereas P. faveolatum has many preopercular pores associated with all four pairs of clear areas.
• Structure: “Female perfectly flat, broad oval, about 4.25 mm long and 3.55 mm broad; no glassy or waxy covering; rich red-brown” (Cockerell & Robinson 1915)
• General Remarks: Good description and illustration of adult female by Hodgson (1994a). The key in the paper, Joshi, S., & Firake, D.M. 2019 First record of Platylecanium nepalense Takagi (Hemiptera: Coccomorpha: Coccidae) from India, with redescription and a key to the species of Platylecanium Cockerell & Robinson, is for species of Platylecanium in the world, but by mistake Joshi wrote it's heading as key to the species known from India.
