Unmounted material. Adult female subglobose, denuded of wax, body appears dark pink to dark purple; legs, eyes and antennae black; dorsal surface thinly covered with white mealy secretion; tufts of wax forming middorsal and marginal longitudinal rows; ventral surface covered with thin white waxy secretion, especially around marsupial opening (adapted from Cockerell, 1896b).

Slide-mounted material. Adult female elliptical, 4.2–5.7 mm long, 3.5–4.4 mm wide (lectotype of I. (Crypticerya) townsendi 5.7 mm long, 4.4 mm wide; lectotype of I. (Crypticerya) townsendi plucheae 5.5 mm long, 4.0 mm wide). Antennae 11 segmented. Eyes, mouthparts and legs as for tribe. Thoracic spiracles as for genus; derm at atrial opening with cluster of 6–8 simple multilocular pores, each with bilocular centre and 6– 10 outer loculi. Hair-like setae distributed as for genus; longest setae forming marginal clusters and between antennae. Flagellate setae distributed as for genus. Multilocular pores, each 12–13 µm in diameter, with bilocular (sometimes trilocular) centre (ventral marginal clusters with bilocular pores only) and 6–12 outer loculi, forming dorsal medial, submedial, submarginal longitudinal rows and marginal clusters and scattered across marginal to submarginal venter; similar smaller pores, each 9–11 µm in diameter, with bilocular (sometimes trilocular) centre and 6–9 outer loculi scattered over rest of derm. Marsupium present, marsupial band shaped as for genus, formed by sparse hair-like setae and simple multilocular pores, each 12–13 µm in diameter, with bilocular or trilocular centre and 6–12 outer loculi, forming band about 4–6 pores wide. Simple multilocular pores, 8–9 µm in diameter, with bilocular centre and 6–10 outer loculi and appearing slightly bluish when stained, scattered on ventromedial to submedial head and thorax; similar pores, 12–13 µm in diameter, with bilocular centre and 4–8 outer loculi, also similar to vulvar pores, scattered within marsupium. Vulvar opening surrounded by hair-like setae and typical multilocular pores, each 13–15 µm in diameter, with elongate centre and 8–12 (mostly 10) outer loculi. Cicatrices round to hourglass shaped, numbering 3, central cicatrix largest. Abdominal spiracles as for genus. Anal ring as for genus; anal opening surrounded by typical multilocular pores and robust hair-like setae.

First-instar nymph as for genus, except each dorsal abdominal segment with no submarginal pore, one submedial pore and one medial pore, and relatively short hair-like setae at abdominal apex in two pairs.

Taxonomic notes. Refer to the C. rileyi group for discussion of similar species.

Refer to Unruh & Gullan (2008: 34) for a discussion of taxonomy of this species. The other material examined has identical collection data to the lectotype and paralectotypes of I. (Crypticerya) townsendi plucheae , but are not included as type material because Cockerell (1896b: 202) stated that he did not have any immature specimens when he described the species.
