(Figs. 1, 4, 5, 16–27)
Description. Coloration & external morphology. Body pale yellow; head with 3 round black spots on dorsal angle of frontoclypeus (central spot situated slightly anterior) and without black spot at tip; fore wing pale with anterior and posterior margins narrowly infuscate; legs and abdominal sterna entirely pale yellow except for tip of tarsi infuscate. Head weakly swollen anteriad, with width 2.5 times as wide as long; pronotum 1.2 times as long as head, with posterior margin weakly concave at middle; female 7th abdominal sternum rectangular, 1.1 times as long as wide, with caudal margin produced posteriad and slightly emarginate at middle; female pygofer (9th tergum) setose along caudal and ventral margins; 3rd valvula (ovipositor) furnished with minute hairs in apical 1/3 and fairly exceeding caudad 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 apical 2/3 and bifurcated at apical half; branches of inner process almost straight, parallel, as long as each other and immediately tapered at apex; ventral branch protruding beyond center of ventral margin of pygofer lobe. Subgenital plate slender, 4.4 times as long as wide, bearing 3 rows of many macrosetae on distal 2/3. Style almost straight,long, with apex reaching apical 1/3 of subgenital plate. Aedeagus robust with dorsal apodeme large; shaft weakly recurved dorsad, slightly narrowed at middle and widened near base in lateral view, with large ventral projection and pair of apical processes; ventral projection tectiform, twice as wide as base of projection, slightly longer and wider than shaft, parallel to shaft; apical process short, directed ventrad; gonopore apical on ventral surface.
Body length (mean). ď, 8.0– 8.9 mm (8.5 mm); Ψ, 8.7–9.6 mm (9.2 mm).
Type material. Holotype: ď (ELKU No. 3317), Shimonagao, Kawane-honchô, Shizuoka Pref., Honshu, Japan, 27. V. 2009, S. Okudera. Paratypes: [Shizuoka Pref.] 12ď 6Ψ (ELKU), Sakurachô-ôi, Tenryû-ku, Hamamatsu, 27. V. 2009, S. Okudera; 13ď 8Ψ (SUU), Harunochô-toyooka, Tenryû-ku, Hamamatsu, 30. V. 2006, S. Okudera; 9ď 11Ψ (SUU), Mt. Ôfuda, Kawane-honchô, 13. VII. 2004, S. Okudera; 9ď 6Ψ (ELKU), same date as holotype; 2ď 1Ψ (ELKU), Mikura, Mori, 11. VI. 2008, 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 probably a close ally to P. protecta in having the bifurcated inner pygofer process and large ventral projection. But it can be easily distinguished by the following morphological features: apex of style reaching distal 1/3 of subgenital plate; ventral margin of pygofer roundly sinuate; aedeagal shaft weakly recurved dorsad and widened near base. In many localities including the type locality, the pygofer process of the male genitalia is usually slender (Fig. 19), but it is somewhat broadened in the specimens from Sakurachô-ôi, Hamamatsu City (Fig. 20). The species name is based on the ancient district name around the type locality, “Tô-tou-mi”.
