Remarks

• Systematics: Ferris & Rao (1947) state that Chionaspis minor was erroneously placed in Pinnaspis, but that its generic status was uncertain. The error arose from Maskell himself, who misidentified specimens sent to him from the West Indies by Cockerell. Upon the basis of this misidentification the name minor was used by Cooley, who placed Chionaspis albizziae Green as a synonym of it and since that time the name has been widely used. Actually, as it has been used it has certainly involved at least two species and very probably more. Therefore, none of the published records which have appeared under the name minor can be definitely assigned to any species until the specimens upon which they were based have been re-examined; although it is probable that most of them refer to Pinnaspis strachani. For a more recent discussion of this confusion, see Henderson (2001a). Henderson (2011) examined specimens collected by Maskell to synonymize Trullifiorinia minima, Pinnaspis dysoxyli, and Chionaspis minor to resolve the situation by creating a new genus, Serenaspis. The specimens that she used were as follows: Fiorinia minima Maskell. LECTOTYPE female, NEW ZEALAND, on an original slide labelled "Fiorinia minima, from ‘Panax’ [=Pseudopanax], female in puparium, Dec. 1882, W.M.M.", [1]: 1 F, pharate and with 1st-exuvium attached, good, cleared, unstained. Barcode NZAC02008427 (NZAC). Chionaspis dysoxyli Maskell. LECTOTYPE female, subsequent designation by Deitz & Tocker (1980: 36): NEW ZEALAND, on an original slide labelled: "Chionaspis dysoxyli, puparium and females, from Dysoxylum, Aug. 1884, W.M.M.", [1]: 1 F, the smaller and clearer of 2 adult females on the slide. Barcode NZAC02008424 )NZAC). Paralectotype: the 2nd female on the above lectotype slide [1]: 1 F (NZAC). Chionaspis minor Maskell. LECTOTYPE female, subsequent designation by Henderson (2001: 89): NEW ZEALAND, on an original slide labelled: "Chionaspis minor, adult female, from Parsonsia, Dec. 1884, W.M.M.", [1]: F. Barcode NZAC02008421 (NZAC).
• Structure: Female scale flat, elongated, oval; 1st exuviae comparatively large, yellow. Male scale rather longer than that of female, but much narrower, carinated. Adult female elongated, segmented, pink. Abdominal segment with edge broken by a number of deepish curvilinear serrations and ending in two inconspicuous median lobes with 3 other smaller lobes on each side (Maskell, 1884).Female puparium thin, flattish, pyriform, white with a faint pink tinge when the egg-mass beneath shows through. 2nd exuviae is comparatively large. Male puparium white, narrow, carinated. Adult female not very deeply corrugated; yellowish red. Abdomen ending in a broken curve with many curvilinear incisions. There are 14 lobes, of which the 2 median are the largest; separated from them by a spine on each side are two others rather smaller; then another spine and a short open space; and then 3 smaller lobes and another spine; another space and then a single small lobe followed by a spine. 5 groups of spinnerets: lowest pair with 12-14 orifices; upper pair with 7-10; uppermost group, 4-6. A few spiny hairs are on the edge of the abdomen (Maskell, 1885a).
• Biology: Most commonly on underside of leaves and often in preference along veins. (Henderson, 2011)
• Economic Importance: Despite this species having been recorded on sugarcane from Colombia, there are good reasons to believe these records were misidentifications. (Caballero, et al., 2017)
• General Remarks: Best description by Maskell (1887a).Best description and illustration by Maskell (1885a).
