( Figs 9–10 View Figs 1–10. 1–2 , 11–12 View Figs 11–15. 11–12 , 38–44 View Figs View Figs ) Type material. HOLOTYPE: ♀, Ryukyus, Sueyoshi park, Naha , Okinawa Pref., 24.iii.1996, N.Takahashi   lgt. ( ELKU). PARATYPES: 6 ♀♀, 15.iii.1996, other data same as holotype   ; 6 ♀♀, 16.iii.1996, other data same as holotype   ; 1 ♀, paratype on slide, collected 15.iii.1996; 1 ♀, paratype on slide, collected 16.iii.1996 ( ELKU, 2 ♀♀ in IEAUG)   .

Diagnosis. Female (length about 1.9–2.7 mm) ( Figs 9–10 View Figs 1–10. 1–2 ). Mesosoma and head ( Figs 11–12 View Figs 11–15. 11–12 ) generally with golden-green metallic reflection; antennae generally brown; all funicle segments longer than wide; pedicel at least slightly shorter to 0.8× as long as F1; legs generally yellow, only basal half of mid coxa and hind coxa brown; wings hyaline; scape about 2× as long as wide; pedicel about 1.5–1.66× as long as wide; F1 about 2–2.45× as long as wide; F6 1.25–1.37 as long as wide; all funicular segments with two lines of longitudinal sensilla; frontovertex about 0.33× as wide as head; fore wing about 2.25× as long as wide; ovipositor not exserted in smaller individuals and in larger individuals exserted part can be 1/6 of gaster.

Male. Unknown.

Description. Female. Holotype 2.03 mm, ovipositor almost not exserted.

Head metallic green with golden reflections and translucent white setae; below toruli golden reflection is more intense; gena with coppery golden-greenish reflections. Malar sulcus prominent. Antenna scape dark brown, funicular segments somewhat lighter. Palpi light yellow colored. Pronotum with faint coppery, golden-greenish reflections; mesoscutum and axillae with green-golden reflection, with very slight coppery reflection; scutellum with golden green reflection; mesopleuron with copery golden-greenish reflections; tegula dirty yellow, with tip somewhat brownish; metanotum and propodeum with coppery-golden reflections; gaster dorsal side with coppery-golden reflections, sides and ventral side with golden-green to coppery reflections; visible parts of gonostyli yellow.

Head in frontal view ( Fig. 41 View Figs ) rounded, 1.2× as wide as high; almost 3× as wide as FV; head on frontovertex with fine, raised, regular, coriaceous-granular sculpture, cells smaller

F 1 has 2 lines of sensilla. F 1 has only the upper line of sensilla.

Dorsal surface of costal cell has two lines of setae. Dorsal surface of costal cell has one line of setae.

HW 2.8× as wide as FV, ocelli forming obtuse triangle. HW 3.4× as wide as FV, ocelli forming right triangle. Ovipositor 4.8× as long as gonostyli. Ovipositor 5.3× as long as gonostyli.

than diameter of eye facet; face and temple with similar, but more elongate and very small reticulate-imbricate sculpture; gena with similar sculpture; ocellar angle about 100°; occipital margin sharp, carinate; eye reaching occipital margin; mesoscutum and scutellum with similar, small, regular polygonal, coriaceous sculpture, however sculpture on mesoscutum deeper ( Fig. 38 View Figs ), which makes it different from that on scutellum; distance between toruli almost 1.35× as long as distance between toruli and clypeal margin and 2× as long as distance from toruli to eye; all funicle segments with longitudinal sensilla place in two rows on each segment ( Fig. 40 View Figs ); mandible as in Fig. 43 View Figs ; fore wing as in Fig. 42 View Figs ; head and mesosoma almost 1.2× as long as gaster; middle tibial spur shorter than basitarsus ( Fig. 39 View Figs ); hypopygium extending to almost basal half; ovipositor almost not exserted; ovipositor as in Fig. 44 View Figs . Relative measurements: HW 40, FV 13, FVL 16, OD 3, OOL 1, OCL 2, AOL 4, POL 7, SL 16, SW 8, MS 11, EL 22, EW 17, ScL 19, ML 22, WS 17, FWL 85, FWW 37.

Relative measurements of paratype: OL 73, GL 15, MT 37, OL 50, GL 10.5, MT 32.

Variation. There is very little variation among the examined females. Ovipositor is either not exserted (in smaller individuals) or exserted part is almost 1/6 of gaster. Antennal funicle segments in smaller individuals shorter than those of bigger individuals.

Comments. The new species is very close with its habitus and morphology to Ps. syntomozae   and Ps. garuga S. Singh, 2011   , but differes in the character given in the Tables 6–7.

Etymology. Named after the Japanese entomologist working on Hemiptera, Dr. Satoshi Kamitani.  

Distribution. Japan: Ryukyus (new record). Endemic.
