Remarks

• Systematics: Within the C. tachardiaformis-group, C. tachardiaformis differs from C. delottoi in having fewer than 20 stigmatic setae in each cleft, from C. elytropappi in having ventral tubular ducts in the cephalic region; and from C. paucispinus in lacking a tibio-tarsal articulatory sclerosis (present and distinct in C. paucispinus), much shorter dorsal setae, and loculate microducts with only 1 or 2 satellite loculi (up to 4 in C. paucispinus). (Hodgson & Peronti, 2012)
• Structure: Unmounted material. "Adult female tests aggregated in huge masses on stems of the host plant, often completely covering the stems for a distance of several inches. Female test Tachardia-like, globular, slightly flattened above, hard, thin, brittle, almost transparent resinous brown, due to the colour of the insect inside; without protuberances but with a slight apical depression containing the opaque white larval exuvia. Adult female denuded of wax moderately dense, globular, smooth and shiny. Caudal protuberance short, very dense, surrounded by a coarsely perforated plate." (Brain, 1920a). Specimens collected by Gullan had dark purple-red wax with distinct white stigmatic bands, whereas those from Vermont on Metalasia had soft white wax. (Hodgson & Peronti, 2012) Mounted material. Young adults broadly oval, without lateral or dorsal protuberances (cephalic and anterior lateral processes well developed; median and posterior lateral ones fused together, forming a single large, broadly rounded process). Stigmatic clefts quite deep. Caudal process conical, pointing dorso-posteriorly. Length about 0.5.?3.0+ (1.0) mm, width 0.5.?2.5+ (0.8) mm. (Hodgson & Peronti, 2012)
