Remarks

• Systematics: http://zoobank.org/B7FD9835-4FAE-4CE0-8B8A-1E11DB6A4705 GenBank accession number KY218988.1; EF-1α, MH915713.1 and KY221285.1; COIII, MH916221.1 and KY220694.1; 16S of primary endosymbiont (Uzinura diaspidicola), KY220094.1 In typical Clavaspis species, the paraphyses are swollen at the anterior end and directed toward the midline of the body or they have a detached knob giving them a mushroom-like appearance. In C. patagonensis, the paraphyses are slightly swollen at the anterior end but they are pointing away from the midline, similar in appearance to those found in species of Diaspidiotus and other near relatives, Recent molecular-phylogenetic studies have shown that Diaspidiotus is radically non-monophyletic and that the true affinities of this species lie with the genus Clavaspis (Schneider et al. 2018). Adult females of C. patagonensis are nearly identical in appearance to C. covilleae (Ferris), but the species are separated on the phylogeny by several other members of Clavaspis. The two can be distinguished based on the shape of paraphyses arising from the lateral angles of median lobes and the distribution of macroducts. Clavaspis patagonensis has fairly narrow paraphyses and possesses one or two dorsal submarginal macroducts on abdominal segment IV. Clavaspis covilleae has broadly swollen paraphyses, typical of Clavaspis, and lacks any submarginal macroducts on abdominal segment IV. The new species could also be easily confused with Diaspidiotus osborni (Newell & Cockerell). In this case, C. patagonensis can be distinguished by possessing submarginal macroducts on IV, having more than one marginal macroduct on at least one pre-pygidial segment, lacking dorsal submarginal microducts on pre-pygidial segments, and having a prosoma that remains membranous in mature adult females. In contrast, D. osborni lacks submarginal macroducts on IV, typically has one marginalmacroduct per pre-pygidial segment, has small groups of dorsal submarginal microducts on pre-pygidial segments, and the prosoma becomes sclerotized in mature adult females. (Schneider, et al., 2020)
• Structure: Adult female presumed to secrete scale cover, not pupillarial. Appearance in life not recorded. Slide-mounted adult female 850–1240 (holotype 1240) μm long, 780–1000 (holotype 1000) μm wide; broadest near mesothorax. Body outline turbinate. Derm membranous throughout at maturity except for light pygidial sclerotization. Antennae simple, each with one spine-like seta.(Schneider, et al., 2020)
• General Remarks: Detailed description and illustration in Schneider, et al., 2020.
