Chlorionidea flava Löw View in CoL
Redescription
General colour white or, more often, distinctly yellow. In this case a middle line from vertex until abdomen tip remains white. Wings hyaline except for their white margin. Dark brown markings only along white carinae of anterior part of vertex and of frons. Area between dark markings of frons orange.
Vertex with nearly parallel or apically slightly converging lateral margins, longer than wide, its apical margin distinctly protruding in the middle. Basal cells longer than wide at their base. Apical cell very narrow, longer than basal cells, its lateral carinae fusing at tip of vertex. Transition vertex – frons in lateral view subangular. Frons in lateral view slightly convex, lateral carina almost straight, its transition to lateral carina of vertex subacutely angular. Frons in frontal view with equally curved lateral margins, in the middle with distinct simple carina continuing on postclypeus. Antennae cylindrical, with basal segment short, broader than long, second segment about three times as long as basal segment, twice as long as broad. Pronotum about three-quarters as long as vertex, its lateral dorsal carinae distinctly diverging, directed to posterior margin without attaining it. Mesonotum in the middle line twice as long as pronotum. Wings (brachypterous) with hind margin widely rounded, without trace of angles, about 1.8 × longer than wide.
Male genitalia. Pygofer ( Figure 4A,E View Figure 4 ) in lateral view with almost straight posterior margin and slight angle above inferior third of hind margin; in posterior view somewhat higher than broad, distinctly broadened on the level of diaphragm with margins strongly protruding in caudal direction on both sides of diaphragm; diaphragm along ventral margin of aedeagus opening with Y-shaped sclerotized thickening, at the end of each of its arms with tubercle; aedeagus opening pentagonal, foramen of styles almost as broad as aedeagus opening. Anal tube ( Figure 5A,F View Figure 5 ) simple, without processes, ventrocaudal margin only slightly excavated. Styles ( Figure 6B View Figure 6 ) stout, with axe-shaped apex, mediobasal portion broadened and scabrous. Suspensorium very uniformly thin on all sides. Aedeagus ( Figure 7A–G View Figure 7 ) laterally depressed, ventrally bent, approximately uniformly wide in lateral view, apically only slightly enlarged, in most cases with phallotreme on its convex right side and curved series of about seven teeth ventrally of phallotreme. On its concave left side dorsoapically with group of about five large teeth and on ventral margin another series of teeth extending over apical half of aedeagus and directed to its left side. Length of aedeagus, shape of apex and shape and number of teeth variable.
Remarks
Anti-symmetry is observed. Some specimens have an aedeagus concave on the right side with phallotreme on the left side etc. ( Figure 7D–G View Figure 7 ). Both types may be found together in the same population (for example in our material from Berchtesgaden, Germany).
Female genitalia. Genital scale ( Figure 9A View Figure 9 ) large, longer than wide, to some degree variable in shape, approximately triangular with concave sides, and tapered, narrowly rounded, tip. Gonocoxae VIII wide, at most slightly concave on their median margin.
