Leptomastix teii Japoshvili , sp. nov.

( Figs 3, 5–6 , 27–30 ) Type material. HOLOTYPE: ♀, no exact location is given, ex Pseudococcus sp. on Citrus , 29.iv.1923, T. Ishii lgt. (ELKU).

Diagnosis. Female (length 1.9 mm) ( Figs 5–6 ). Head and mesosoma mostly orange with only dorsal side of mesosoma, tip of ventral side of mesosoma and small spot behind fore coxa brown. Antenna with radicle brown; scape yellow with dorsal margin brown; pedicel and flagellum generally brown, pedicel yellowish in some aspects; F 1 2× as long as pedicel and 0.75× as long as clava; F 6 about 2× as long as wide. Fore wing nearly 3× as long as wide; costal cell narrow, marginal vein longer than stigmal and postmarginal vein; postmarginal vein longer than stigmal; linea calva interrupted by 3 lines of setae. Gaster longer than mesosoma and apically pointed; ovipositor not exserted.

Male. Unknown.

Description. Female. Length 1.9 mm (holotype).

Head and mesosoma generally orange yellow; mesosoma mostly orange, but brown dorsally and immediately behind fore coxa. Antenna with radicle brown; scape yellow with dorsal margin brown; pedicel and flagellum brownish; pedicel yellow in some aspects. Legs orange- -yellow with only basal half of hind tibia a little darker. Head on FV between anterior ocellus and top of scrobes with fairly regular, hexagonal, reticulate sculpture of mesh size subequal to diameter of an eye facet; ocelli forming about a 90° angle ( Fig. 3 ); lowest margin of antennal torulus slightly bellow lowest eye margin. Antenna as in Fig. 27 . Relative measurements: HW 97, FV 40, FVL 35, OD 5, OOL 7, OCL 10, POL 13, AOL 10, MS 16, EL 40, EW 26.

Mesosoma ( Fig. 30 ) dorsally with very fine coriaceous sculpture with mesh on mesoscutum slightly smaller than that on scutellum. Linea calva interrupted by 3 line of setae; wing setation as in Fig. 28 ; marginal vein longer than postmarginal and stigmal veins combined; postmarginal vein longer than stigmal vein; metasoma 1.25× as long as mesosoma; ovipositor ( Fig. 29 ) not exserted. Relative measurements: OL 48, GL 9, MT 85.

Differential diagnosis. The new species is very close to L. tsukumiensis , but differs as shown in Table 4.

Etymology. Named after the Japanese specialist on Encyrtidae, Prof. Dr. Tei Ishii.

Distribution. Japan (new record).
