Kamitani, Satoshi, Higuchi, Toshiyuki & Okudera, Shigeru, 2012, Taxonomic study of the protecta - group in the genus Pagaronia Ball (Hemiptera, Cicadellidae, Evacanthinae) from Japan, Zootaxa 3343, pp. 1-15 : 11

Pagaronia lanceolata sp. nov.

( Figs. 3 , 4 , 7 , 44–54 )

Description. Coloration & external morphology. Head and thorax ochraceous with fuscous markings; frontoclypeus with 3 small black spots on dorsal angle (central spot often slightly larger); fore wing pale ochraceous, widely infuscate at apical and posterior margins. Head swollen anteriad, 2.2 times as wide as long; pronotum weakly obscured near posterior margin, 1.2 times as long as head; female 7th abdominal sternum pentagonal, 0.9 times as long as wide, with caudal margin produced posteriad and slightly emarginate at middle.

Male genitalia. Pygofer lobe slender, furnished with about 10 short setae near caudal margin, narrowed near base and weakly sinuate at ventral margin, with inner process not forked; inner process long and robust, almost straight but bent at apical 1/6, parallel to ventral margin of pygofer lobe, protruding beyond caudal margin. Subgenital plate oblong, 4.2 times as long as wide, bearing many macrosetae on distal 2/3. Style slightly bent dorsad near apex, with tip slightly hooked ventrad; apex of style reaching about half length of subgenital plate. Aedeagus robust; dorsal apodeme very small; shaft slightly widened at apex in lateral view, with widened ventral projection and pair of apical processes; ventral projection tectiform, as long as shaft, distinctly wider than shaft and 3 times as wide as shaft; apical process very short; gonopore apical on ventral surface.

Body length. ď, 9.0 mm; Ψ, 9.6 mm.

Type material. Holotype: ď (SUU), Dôdaira, Tennoji-one, Tanzawa Mts., Kanagawa Pref., Honshu, Japan, 17. VII. 1993, K. Takahashi. Paratype: [Kanagawa Pref.] 1Ψ (SUU), Mt. Ôyama, Tanzawa Mts., 14. VII. 1980, M. Hayashi. The holotype is deposited in the Department of Biology, Faculty of Education, Saitama University, Saitama, Japan.

Distribution. Japan (central Honshu: Kanagawa Prefecture).

Remarks. This species is similar to Pagaronia conformata in habitus, but differs in the shape of the inner pygofer process and ventral projection of the aedeagus. Furthermore, it is also somewhat similar to P. s p i n o s a in the sinuation of the inner pygofer process, but differs in having the inner pygofer process wider, the dorsal apodeme of aedeagus very small, and the ventral projection of the aedeagus short and much widened. This condition of the aedeagus is unique within the protecta -group.
