DeLONG, Department of Entomology, Ohio State University, Columbus, OH 43210OHIO J. SCI. 82(3): 140, 1982A green gyponine leafhopper, P. sinverdan. sp. from Peru, which is intermediate inform between Gypona and Hecalapona andwhich apparently should not be placed ineither genus, is described and placed in anew genus, Platypona.Platypona new genusHead narrower than pronotum; crownthin, flat, foliaceous and produced as inHecalapona, but more triangular, withrounded apex, like Gypona in being shorterthan basal width between eyes. The malegenital styles are elongate, thread-like andthe aedaegus bears slender processes thatarise at base of shaft, extend along and arecontiguous with shaft, to its apex. Thepygofer bears a long spine-like processwhich extends along inner margin, eachside, from the median dorsal margin tonear apex of pygofer. Type-species Platy-pona sinverda n. sp.Platypona sindveda (Fig. 1.)Length of male 8.2 mm, female un-known. Crown produced, flat, foliaeceous,XA wider at base between eyes than medianlength. Color dull green. Crown with areddish brown elongate marginal spot,each side, half way between eye and apex.Scutellum with brown basal angles;median portion pale brown. Forewingsgreen anterior to a diagonal brown line ornarrow band extending from tip of clavusto 2A length of costa, apical portion ofwing beyond brown coloration, whitishhyaline with red veins.Male genitalia with plates 41/2 times aslong as median width, apex narrowed,bluntly pointed. Style elongate, slender,rod-like, apical portion tapered to a fila-mentous tip and bearing a short, slenderthorn-like spine on dorsal margin at 4/5 itslength. Aedeagal shaft slender at base, inventral view, broadened medially, slightlynarrowed at apex that is broad and blunt,bearing a short curved hook each side, ex-tending laterally. A pair of slender rod-likeprocesses arise at base of shaft and extendproximal to it, on ventral margin, to apex,where each is bent basolaterally, formingslender crossed apices, one-fifth length ofshaft. Pygofer with a broad process arisingdorsally inside pygofer wall and extendingventrocaudally, narrowed at 2A its length,forming a slender curved apex.Holotypemale, Sinchona, Peru, Novem-ber 1943, J.
