Diagnosis. Female (length about 1.0– 1.3 mm) ( Figs 14–15 View Figs 11–15. 11–12 ). Head ( Fig. 13 View Figs 11–15. 11–12 ) and mesosoma brown with golden green to coppery metallic reflections; antennae generally dirty yellow; not all funicle segments longer than wide; pedicel 1.8× as long as wide and 2.4× as long as F1; legs generally yellow, only mid and hind coxae, last tarsal segment, hind femur and fourth hind tarsal segment brown; wings hyaline; scape about 3.9× as long as wide; F



Ps. higashiurai   sp. nov. Ps. colposceniae  

FV almost 0.5× as wide as HW. FV 0.33× or slightly less as wide as HW.

Ocelli in slightly obtuse triangle. Ocelli in slightly acute triangle.

Clava almost as long as flagellar segments combined. Clava shorter than flagellar segments combined.

quadrate 1× as long as wide; F –F transverse, F 1.1× as long as wide; all funicular segments 2 5 6

with two lines of longitudinal sensilla ( Fig. 45 View Figs ); frontovertex about 0.33× as wide as head; fore wing ( Fig. 48 View Figs ) about 2.7× as long as wide; middle tibial spur as in Fig. 46 View Figs ; exserted part of ovipositor ( Fig. 47 View Figs ) 0.16× as long as gaster including exserted part.

Male. Unknown.

Description. Female. Holotype 1.2 mm, including exserted part of ovipositor.

Head metallic green with golden reflections and translucent white setae; front above torulli and in front of anterior ocellus with brown band without metallic reflection; genae with goldengreenish reflection. Malar sulcus prominent. Antenna with scape almost yellowish, funicular segments yellow; clava with C2–C3 dirty yellow. Palpi light yellow. Pronotum with at least some kind of coppery with golden green reflections; mesoscutum and axillae golden-green with very reduced coppery reflections; scutellum with golden-green reflections; mesopleuron with coppery golden reflections, with coppery reflection more intensive; tegula brown, with golden metallic reflections; metanotum and propodeum with copperygolden reflections; gaster dorsal side with first tergite coppery golden, remaining tergites with coppery silver reflections; ventral surface with golden-green to coppery reflections; visible parts of gonostyli brown.

Head in frontal view 1.3× as wide as high; almost 3× as wide as FV; head on frontovertex with fine, raised, regular, coriaceous-granular sculpture, cells smaller 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 structure, however mesoscutum with sculpture deeper, which makes it different from that of scutellum; distance between toruli almost 1.56× as long as distance between toruli and clypeal margin and 1.08× as long as distance from torulus to eye; sensilla visible only on F6; mandible with one tooth and truncation; head and mesosoma almost 1.7× as long as gaster; middle tibial spur as long as basitarsus ( Fig. 46 View Figs ); hypopygium extending to almost basal half; ovipositor exserted; ovipositor as in Fig. 48 View Figs . Relative measurements: HW 44, FV 20, FVL 22, OD 3, OOL 2, OCL 4, AOL 7, POL 10, SL 20, SW 5, MS 14, EL 13, EW 19, ScL 24, WS 12.

Differential diagnosis. The overall morphology of this new species is very close to Ps. syntomozae   and Ps. colposceniae Trjapitzin, 1969   , but differs in the character given in the Table 8.

Etymology. Named after Japanese biologist and biocontrol specialist working on Encyrtidae, Yoshimitsu Higashiura.  

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