Spanioza Enderlein, 1926 , sensu novo

Diagnosis. Adult. Head slightly narrower than mesonotum; in profile inclined at about 45° from longitudinal body axis. Vertex shiny, weakly produced anteriorly on either side of mid-line. Genal processes variable in size and shape, conical, subacute, ranging from one to two thirds vertex length. Antenna 10-segmented, segment 3 always whitish, longer than segments 4 and 5 together; segment 10 bearing one long and one very short terminal seta. Clypeus short, pyriform. Thorax weakly curved dorsally. Metacoxa without anterior lobe; with horn-shaped, subacute meracanthus; metatibia weakly widened basally and apically, with some minute basal spines and 1+3 sclerotised apical spurs. Forewing transparent, variable in size, shape and colour, elongate, strongly pointed, angular or bluntly angular apically; vein Rs short, bifurcation of vein M slightly or strongly distal to line linking apices of veins Rs and Cu la; wing membrane transparent; apart from wing base usually lacking surface spinules, with the exception of T. velutina where spinules are always present, forming more or less extended fields. Radular spinules forming narrow stripes in cells m 1, m 2, and cu 1. Hindwing membranous, about two thirds forewing length; veins R and M with short common petiole; marginal setae distal to costal break grouped. Lateral setae on abdominal tergites restricted to the first (and rearely second) visible segment. Male proctiger weakly produced or lobed posteriorly, covered in moderately long setae apically and posteriorly. Subgenital plate subglobular, with a few long setae laterally and ventrally. Paramere shorter than proctiger, massive or lamellar. Distal portion of aedeagus relatively short with large apical dilatation which varies from almost rectangular to distinctly hooked; sclerotised end tube of ductus ejaculatorius short, weakly curved. Female proctiger short with relatively large circumanal ring. Subgenital plate short.— Fifth instar immature. Body oval, bearing a single row of densely spaced, lateral truncate sectasetae. Antenna 6-segmented. Legs with short claws and small, fan-shaped tarsal arolium. Humeral lobes blunt, relatively short. Circumanal ring small, with a single row of pores.

Comments. In the «best ML tree» of Percy et al. (2018: Figure S2 ), Trioza galii Foerster, 1848 constitutes, with good support, the sister taxon to a clade comprising Dyspersa , as defined above, Hemitrioza Crawford, 1914 , and T. tatrensis Klimaszewski, 1965 . The species of this clade are only distantly related to and not congeneric with Trioza urticae ( Linnaeus, 1758) , the type species of Trioza . Trioza galii , the type species of Spanioza , and following three species constitute a likely monophyletic group which was diagnosed by Burckhardt & Lauterer (2006). Here we propose to use the name Spanioza for the species of the Trioza galii complex composed of Spanioza cocquempoti ( Burckhardt & Lauterer, 2006) , comb. nov., S. drosopouli ( Burckhardt & Lauterer, 2006) , comb. nov., S. galii ( Foerster, 1848) and S. velutina ( Foerster, 1848) . The narrow concept adopted here is in line with Burckhardt et al. (2021).
