Diagnosis.

The two known species of the genus are very similar morphologically. J. jamesi is a larger species (usually its body length is at least 0.5 mm larger than J. sydneyae ) and T2 is comparatively less broad apically (T2 width at posterior margin 1.8 -2.3 × width at anterior margin, whereas J. sydneyae has T2 width at posterior margin 3.0 × width at anterior margin). The known geographical distribution of the two species is also different, with J. jamesi found at lower altitudes in southern Thai land and Vietnam (75-100 m), whereas all known specimens of J. sydneyae have been collected at higher altitudes (273-924 m). DNA barcodes of the two species also have more than 2% of base pair differences.

Description.

Female. Body mostly yellow to yellow-white, with only antennae brown (light brown ventrally, dark brown dorsally), posterior 0.2 of metatibia and metatarsus dark brown to black; base of mandible slightly discolored (with paler spot); wings hyaline, veins dark brown. Body mostly smooth, with very shallow and sparse punctures in some areas. Flagellomeres with placodes arranged in three rows. Head posteriorly with a deep depression, behind occiput. Hypostomal carina with projecting flange. Mesosoma mostly smooth. Scutoscutellar sulcus with some 6 strong crenulae. Propodeum entirely smooth, without any carina. Metatrochantellus with unique shape (better illustrated in Fig. 23I ), anteriorly with rounded projections. Relatively very large (0.8 × as long as first segment of metatarsus) and thick inner spur in hind leg. Fore wing with large areolet. Hind wing with vannal lobe fully setose. Metasoma mostly smooth. Ovipositor extremely short, almost invisible externally. Body measurements (mm). F2 L: 0.33 (0.29-0.33); F3 L: 0.33 (0.29-0.33); F14 L: 0.29 (0.25-0.29); F15 L: 0.27 (0.23-0.27); Malar sulcus L: 0.10 (0.09-0.10); Mandible W: 0.13 (0.11-0.13); T1 L: 0.53 (0.52-0.54); T1 W at posterior margin: 0.18 (0.13-0.15); T1 maximum W: 0.27 (0.22-0.26); T2 W at anterior margin: 0.15 (0.15-0.18); T2 W at posterior margin: 0.33 (0.30-0.37); T2 L: 0.33 (0.29-0.38); Metafemur L: 1.44 (1.29-1.45); Metafemur W: 0.42 (0.38-0.42); Metatibia L: 1.57 (1.44-1.63); Inner spur L: 0.75 (0.68-0.78); Outer spur L: 0.39 (0.34-0.40); First segment of Metatarsus L: 1.00 (0.91-1.00); Ovipositor sheaths L: 0.08 (0.05-0.07); Body L: 3.84 (3.66-3.92); Fore wing L: 4.08 (3.64-4.08). Maximum W of T1 is taken at anterior margin of T1 for all specimens. T1 L is approximate for 3 specimens and impossible to measure for 2 specimens. Fore wing L is approximate for 2 specimens.

Biology.

Host unknown.

Distribution.

Thailand, Vietnam.

Molecular data.

The holotype and 9 paratype sequences all belong to BIN BOLD:AAH1239, which is 1.5 % different from the closest Microgastrinae in BOLD (specimens of an undescribed species of Jimwhitfieldius ).

Etymology.

Named after James B. Whitfield in appreciation of the many things the first author has learned from him.
