Possible junctions or synapses between bristle cells and adjacent
lamellate body cells, nervous elements, or other types of cells in the epithelial floor need to be identified and mapped.
33 x projecting posteriad with apex conical but it can easily be separated from the same latter being larger species, lateral margins of pronotum of much prominently curvate and narrowly
lamellate and sides of venter strongly coarsely punctate.
Telopodite long, with
lamellate femoral process curved through about 300[degrees] (Fig.
tonnaichanus Muramoto, known from temperate eastern Asia (Yasunaga, 2001; Yasunaga and Vinokurov, 2000), but it can be distinguished from the latter Psallus members by the short, apically darkened antennal segments II and III, the paler apical part of each femur, and the
lamellate, semicircular parempodia.
The pretarsus is also distinctive, with the distally angulate claws (11-1), greatly expanded
lamellate parempodia (12-1), and greatly enlarged pulvilli (13-1).
These cells apparently secrete the pharyngeal cuticular intima, consisting of three layers: the
lamellate endocuticle, the exocuticle with trabeculae-bound spaces and the thin epicuticle lining the luminal surface.
Urodidae can be characterized by 5 possible autapomorphies: the
lamellate male antennae, a hair-pencil on the base of the male hindwing costa; the larval prothorax without seta MXD1; the larval abdominal segment VIII with L3 ventroanterior to L1 and L2 and SV1 almost as high as L3; the larval prolegs elongate, medially constricted, with mesoseries of crochets (Kyrki 1988; Dugdale et al.
5 whorls; sculpture strongly cancellate; first whorl initially sculptured only with widely spaced, rib-like, axial pliculae (ca 15), but 3 spiral cords develop soon thereafter, one forming shoulder, another level with the abapical suture and the third between these at whorl periphery; cords persist and become progressively stronger with growth; an additional (fourth) subsutural cord may or may not develop on the shoulder during the last or penultimate whorl; no intermediary spiral cords; intervals between cords wider than cords themselves; last adult whorl with 20-30 axial pliculae; pliculae narrower than cords and somewhat
lamellate, sometimes raised into squamose nodules where they cross cords; interstices obliquely quadrate.
Profemora triangular in cross-section, with anterodorsal carina raised and posterodorsal carina considerably lowered; medioventral carina distinct,
lamellate and more or less conspicuously displaced towards anteroventral carina.
5 whorls; initial whorls rounded, becoming more flat-sided with growth; suture narrowly indented; sculpture of spiral cords and
lamellate axial pliculae; first whorl sculptured only by relatively widely spaced axial pliculae (13), second whorl with 16 axial pliculae and 2 developing spiral cords; third whorl with 17 axial pliculae and a third spiral cord developing at shoulder; fourth and fifth whorls with 3 strong spiral cords and 18 and 19 axial pliculae respectively; cords and pliculae subequal in strength, their intersections produced into scale-like nodules, those on shoulder cord somewhat more rounded; suture level with subperipheral cord; cord intervals wider than cords themselves, that between peripheral and subperipheral cord deep.
Ventral margin of anal segment incised medially; genital styles short,
lamellate B.
Among the more conspicuous and unique differences between the new species and previously described congeners are the foreshortened adult antennae, the bowed instead of bent tarsal claws, the short empodia, the broad and completely setulose gonostylus, and the
lamellate terminal segment of the larva.
