description: Icerya sumatrana Rao   
 Icerya sumatrana Rao, 1951b: 137.   
 Unmounted material. Body of adult female dark brown, covered by thick cream-yellowish waxy secretion; ovisac fluted, nearly as long as body, projecting from posterior end of body (Rao, 1951b).   
 Slide-mounted material. Adult female oval, 3.6–4.8 mm long, 2.3–3.5 mm wide (holotype 3.9 mm long, 3.2 mm wide). Antennae 11 segmented (one paratype with 9-segmented antennae). Eyes, mouthparts and legs as for tribe. Thoracic spiracles as for genus. Hair-like setae scattered across derm, longest around margin, between antennae and in vague transverse rows on dorsal surface. Flagellate setae as for genus. Open-centre pores, each 15–16 µm in diameter, 17–18 µm long, with 7 or 8 outer loculi, in clusters of 1–4 around margin. Simple multilocular pores, each 12–14 µm in diameter, with bilocular centre and 6–8 outer loculi, associated with open-centre pores. Simple multilocular pores, each 10–12 µm in diameter, with bilocular centre and 6–8 outer loculi, covering dorsal surface. Simple multilocular pores, appearing slightly bluish when stained, each 7–8 µm in diameter, with bilocular or trilocular centre and 5–8 outer loculi, forming submarginal longitudinal row on ventral surface. Ovisac band made of simple multilocular pores of two types: (i) pores forming inner ovisac band 5 or 6 pores wide, each pore 8–9 µm in diameter, with bilocular centre and 6–8 outer loculi, and (ii) pores, appearing slightly bluish when stained, forming outer band 5–7 pores wide, each pore 7–8 µm in diameter with bilocular or trilocular centre and 5–8 slightly reniform outer loculi. Simple multilocular pores, each 9–10 µm in diameter, with bilocular centre (appearing reniform) and 4 or 5 outer loculi, forming transverse rows on ventromedial abdomen and scattered on ventromedial head and thorax. Vulvar opening as for genus. Cicatrices oval to round, numbering 3, central cicatrix slightly larger than lateral cicatrices. Abdominal spiracles in 2 pairs. Anal tube as for genus; anal opening as for genus, surrounded by robust hair-like setae and typical multilocular pores with trilocular centre and 10–14 outer loculi.

 Taxonomic notes. Refer to “ Pericerya ” group for a discussion of similar species.   
The World Catalogue listed only the holotype collection information (Ben-Dov, 2005: 225). Rao (1951b: 139) described this species from several slides and dry specimens present in the USNM collection, but we did not find any dry material in the collection. Presumably, the dry material has since been slide-mounted. Complete type collection data are provided above.
