Platylecanium elongatum Takahashi, 1951 b: 104 View in CoL .
Comments. Platylecanium elongatum was collected on the leaves of a palm on the Riau (Riouw) Is and does not appear to have been collected since. From Takahashi’s (1951) original description, the main character-states diagnosing this species are: (i) body elongate, about 2.3 times longer than wide (4.2‒4.7 mm long); (ii) dorsum without areolations; (iii) with 4‒7 preopercular pores present around some clear areas; (iv) anal plates together about as long as combined widths, each plate with a pointed apex and posterior margin slightly longer than anterior margin; (v) stigmatic clefts each with 3 stigmatic spines; (vi) stigmatic spines longer than marginal setae, each stout and tapering, but not reaching margin; (vii) stigmatic spines subequal in length or with median spine shorter than lateral spines; (viii) margin not crenulated; (ix) marginal setae sparse, setose and short, with 14‒22 on each side between stigmatic clefts, and (x) antennae rudimentary and pointed apically.
In having: (i) an elongate body, 2.3 times longer than wide; (ii) a non-crenulate margin; (iii) only 3 stigmatic setae in each cleft; (iv) very short antennae, and (v) anal plates each with a distinctly pointed apex, P. elongatum somewhat resembles P. dendrobii (described as new above) and P. cyperi . Based on Takahashi’s description and figures, P. elongatum differs from P. dendrobii in having: (i) short stigmatic spines, which are subequal in length and do not reach the margin (those of P. dendrobii are much longer, with the median spine reaching the margin), and (ii) each side with possibly more marginal setae between the stigmatic clefts (about 14‒22 on P elongatum but only 6‒10 on P. dendrobii ). Platylecanium elongatum differs from P. cyperi in lacking dorsal areolations ( P. cyperi has a broad submarginal band of areolations).
