Revision of Chlorionidea Löw (Hemiptera: Delphacidae) with the description of two new species from Italy, and comments on anti-symmetry in male genitalia of Delphacidae Author Guglielmino, Adalgisa Author Bückle, Christoph text Journal of Natural History 2010 2010-11-05 44 45 - 46 2737 2759 http://dx.doi.org/10.1080/00222933.2010.512399 journal article 10.1080/00222933.2010.512399 1464-5262 5212071 Chlorionidea bromi Emeljanov Redescription Very similar to C. flava in shape, proportions, size, colour and markings. Head shape similar to that of C. sibillinica (see below). The differences from that species comprise mainly characters of male and female genitalia. In the material examined only brachypterous specimens were present. Male genitalia ( Figure 2B ). Pygofer ( Figure 4C,G ) smaller than in C. flava . In lateral view with upper part of hind margin slightly oblique in anterior direction, forming in this way a distinctly protruding angle above inferior third of hind margin; in posterior view without sclerotized thickening on ventral margin of aedeagus opening, but with distinct, in its ventral part more elevated, median carina between the two foramina; styles opening small, its width at most a third of width of pygofer. Anal tube ( Figure 5C,H ) normally simple [only in one of two males from Crimea ( Figure 5D,I ), however, with pair of short, straight, ventrally directed spines], its ventrocaudal margin profoundly excavated. Styles ( Figure 6D ) slender, without darker or scabrous inner basal margin, apical part narrow, not broadened at tip. Suspensorium shorter and more robust than in C. flava , its caudal margin prolonged in short lamella with concave margin. Aedeagus ( Figure 8E–G ) relatively short, curved in dorsal direction, dorsoventrally depressed, dorsally concave, on its left margin with row of dorsally directed teeth along apical half of aedeagus, on its right margin another group of teeth in two rows in subapical position, phallotreme in ventral position. Remarks Anti-symmetry in the aedeagus is observed: Some specimens have the subapical group of teeth on left side. Female genitalia. Without sclerotized genital scale. Gonocoxae VIII ( Figure 9D ) distinctly excavated on their basal inner margin, caudally broadened. Measurements Males (brachypterous). Total length: 3.3–3.4 mm ; width at level of wings: 1.2– 1.26 mm ; width of head including eyes: 0.74–0.81 mm ; length of vertex: 0.34–0.42 mm ; width of vertex at base: 0.28–0.33 mm ; length of pronotum: 0.22–0.25 mm ; length of mesonotum from hind margin of pronotum to tip of scutellum: 0.47–0.54 mm ; length of forewing: 1.28–1.5 mm ; width of forewing: 0.77–0.82 mm ; length of hind tibia: 0.85–0.9 mm ; length of aedeagus: 0.45–0.48 mm . Females (brachypterous). Total length: 3.8 mm ; width at level of the wings: 1.32– 1.4 mm ; width of head including eyes: 0.81–0.83 mm ; length of vertex: 0.38–0.43 mm ; width of vertex at base: 0.33–0.36 mm ; length of pronotum: 0.24–0.25 mm ; length of mesonotum from hind margin of pronotum to tip of scutellum: 0.52–0.55 mm ; length of forewing: 1.4–1.58 mm ; width of forewing: 0.8–0.9 mm ; length of hind tibia: 0.93–0.95 mm .
