Description

(N = 11). Adult female presumed to secrete scale cover, not pupillarial. Appearance in life not recorded. Slide-mounted adult female 730-1110 (holotype 860, median 860) μm long, 590-800 (holotype 680, median 680) μm wide; broadest near mesothorax and metathorax. Body outline nearly oval. Derm membranous except for pygidium. Antennae simple, each with one thick, flagellate seta; distance between antennae 120-150 (median 130) μm. Without disc pores near anterior or posterior spiracles. Lobes: Pygidium with 2 pairs of well-developed sclerotized lobes extending from pygidial margin. Median lobes (L1) prominent and broad, roughly rectangular in shape with ragged edges; each lobe with basal scleroses nearly equal in length to L1, broad basally and tapering anteriorly; L1 separated by interlobular space about 1/4 width of L1; second lobes (L2) about 1/2 width of L1, smoothly rounded apically, without notches, L3 and L4 absent. Paraphyses: Absent. Plates: 1 pair of simple plates between L1, with shallow bifurcations, not deeply fringed, slightly longer than L1; 2 plates present in first space between L1 and L2, the plate immediately anterior to L1 simple and roughly triangular, the other roughly rectangular and apically fringed, both longer than L1; 2 plates anterior to L2, variously fringed, ranging from simple to fimbriate; plates absent beyond setae marking position of L3. Ducts: Dorsal pygidial macroducts of 1-barred type, long and slender, duct filaments about 6-8 times as long as width of orifices; 1 macroduct between L1 (rarely absent), extending beyond posterior margin of anal opening, 40-51 (median 45) μm in length; 5-9 clustered macroducts arising from first space between L1 and L2, 14-27 on abdominal segment VI, in elongate cluster arising from second space and widening anteriorly; 18-38 ducts on abdominal segment V, in irregular, elongate cluster arising from third space and widening anteriorly; 38-66 (median 48.5) macroducts on each side of pygidium in total. Submarginal cluster of 4-17 (median 11) macroducts present on abdominal segment IV; few marginal macroducts present on each of abdominal segments I-III and metathorax. Dorsal submedial groups of microducts present on each of abdominal segments I-III. Small clusters of ventral submarginal microducts present on abdominal segments II-VI. Anal opening: Small and slightly oval, 11-17 (median 14) μm in diameter, positioned 2.2-3.3 (median 2.3) anal lengths from base of L1, located in posterior third of pygidium. Perivulvar pores : Absent.

DNA sequences.

Several DNA sequences of Chortinaspis jujuyensis sp. nov. have been published, including fragments of 4 loci. None are from the holotype or paratypes, but all are from specimens collected in the same collecting event with the same data. Specimen D0265A was ground to powder during DNA preparation. Specimens D0265E and D0265F are mounted on microscope slides but are in poor condition; they are identifiable as C. jujuyensis sp. nov. but were not suitable for reliable measurements and therefore were not designated as paratypes. The sequenced loci and corresponding GenBank accession numbers are: the large ribosomal subunit (28S; D0265A, DQ145314.2; D0265F, MH933984.1), elongation factor 1-alpha (EF-1α; D0265A, DQ145426.1; D0265E, MH915708.1; D0265F, MH915709.1), carbamoylphosphate synthetase (CAD; D0265E, MH915983.1; D0265F, MH915984.1), and cytochrome oxidase I and II (COI-II; D0265, GQ424990.1; D0265E, MH916219.1 & MH916391.1; D0265F, MH916220.1 & MH916392.1). The small ribosomal subunit (16S) sequences of the primary bacterial endosymbiont, Uzinura diaspidicola , of C. jujuyensis sp. nov. has also been published: GQ424853.1.

Informal synonyms.

Specimens of C. jujuyensis sp. nov. have appeared in several published phylogenetic trees, and have been referred to variously as " Diaspidiotus sp undesc #2" ( Morse and Normark 2006; Rugman-Jones et al. 2010), " Diaspidiotus sp. undesc." ( Gruwell et al. 2009), " Diaspidiotus sp" ( Andersen et al. 2010), and " Chortinaspis ud0265" ( Schneider et al. 2018; Normark et al. 2019).

Remarks.

Chortinaspis jujuyensis sp. nov. shares similarities with C. graminella (Cockerell) and C. frankliniana Ferris. The median lobes of C. jujuyensis sp. nov. are apically truncate or nearly rectangular in shape like those of C. graminella and have rough apical edges like those of C. frankliniana . But C. jujuyensis sp. nov. can be distinguished from both species by its narrow, smooth second lobes, in contrast to the broadly truncate and notched second lobes seen in the other two species. It differs from C. chortina (Ferris) in that it lacks any plates anterior to the position of the third lobes.

Host plant.

Not recorded.

Etymology.

The specific epithet is an adjective formed from the name Jujuy, the province in which it was found + the suffix - ensis, meaning of or from a place.

Distribution.

Argentina (Jujuy).
