description: Pagaronia dichotoma sp. nov.
(Figs. 2, 4, 6, 28–39)
Description. Coloration & external morphology. Very similar to preceeding species in body hue and infuscation on fore wing. Frontoclypeus with 3 small black spots arranged on line. Head roundly swollen anteriad, 2.4 times as wide as long; pronotum 1.2 times as long as head, with posterior margin weakly concave at middle; female 7th abdominal sternum oblong, 1.2 times as long as wide, with caudal margin weakly produced posteriad and slightly emarginate at middle; female pygofer setose along caudal and ventral margins; 3rd valvula sparsely pilose in apical 2/3 and distinctly exceeding beyond pygofer.
Male genitalia. Pygofer lobe oblong, furnished with about 10 short setae near caudal margin, narrowed near base and roundly sinuate at ventral margin, with inner process bent caudad at basal 1/4 and bifurcated at apical 2/3; dorsal branch straight and longer than ventral one; ventral branch parallel to dorsal one, protruding beyond center of ventral margin of pygofer lobe. Subgenital plate elongate, 3.8 times as long as wide, bearing about 35 macrosetae on distal half. Style slightly bent dorsad near apex, with tip slightly hooked ventrad; apex of style reaching distal 1/3 of subgenital plate. Aedeagus robust; dorsal apodeme robust; shaft wide and almost straight in lateral view, with ventral projection and pair of apical processes; ventral projection tectiform, widened at apical half, shorter than shaft, almost parallel to shaft; apical process short, directed ventrolaterally; gonopore apical on ventral surface. Anal tube (10th segment) cylindrical, almost as long as pygofer lobe.
Body length (mean). ď, 7.9–9.0 mm (8.6 mm); Ψ, 8.9–9.5 mm (9.2 mm).
Type material. Holotype: ď (ELKU No. 3318), Higashi-fujikawa, Kawane-honchô, Shizuoka Pref., Honshu, Japan, 10. VI. 2010, S. Okudera. Paratypes: [Shizuoka Pref.] 15ď 18Ψ (ELKU), same date as holotype; 1ď 1Ψ (ELKU), Itchô-gôchi, Kawane-honchô, 10. VI. 2010, S. Okudera; 2ď 2Ψ (ELKU), Sasamashimo, Kawane-honchô, 11. VI. 2008, S. Okudera; 1ď 3Ψ (ELKU), Okabechô-nodasawa, Fujieda, 10. VI. 2010, S. Okudera; 1ď (ELKU), Okabechô-okabe, Fujieda, 10. VI. 2010, S. Okudera; 3ď 11Ψ (ELKU), Setonoya, Fujieda, 11. VI. 2008, S. Okudera; 2ď 1Ψ (ELKU), Sakanokami, Aoi-ku, 10. VI. 2010, S. Okudera; 4ď 1Ψ (ELKU), Mariko, Suruga-ku, Shizuoka, 10. VI. 2010, S. Okudera. The holotype is deposited in the Entomological Laboratory, Faculty of Agriculture, Kyushu University, Fukuoka, Japan.
Dsitribution. Japan (central Honshu: Shizuoka Prefecture).
Remarks. This species is similar to P. protecta and P. totoumiensis sp. nov. in general appearance and having the bifurcated inner pygofer process, but it is distinguishable from them by the shape of aedeagal shaft and relative length of the ventral projection. A male paratype from Sakanokami, Shizuoka City shows some differences in the shape of the inner pygofer process: the dorsal branch is bifurcated and not protruding beyond the caudal margin (Fig. 32).
