Oodera regiae Yang, 1996: 98, 310.

Diagnosis.

FEMALE (N = 1). Small-sized (6.25 mm). Head and mesosoma dark green to green. Fore wing hyaline. Body robust (mesonotum 1.25 × as long as wide). Head oval (1.58 × as high as long). Eyes large (0.69 × as high as head) (Fig. 10g View Figure 10 ). Corona very short (0.45 × as long as eye height), thick (4.0 × as long as wide), structure continuous (Fig. 7g View Figure 7 ). Pronotum pentagonal with posterior part distinctly narrowing towards mesoscutum, with broadest part at midlength (Fig. 13g View Figure 13 ). Mesoscutellum normal (0.63 × as long as wide), anterior margin hardly convex (part anterior to imaginary transverse line connecting posterior margins of axillae less than 1/3 of mesoscutellum length; 0.26), mesoscutellum densely lineate in anterior half, rugulose in posterior half (Fig. 16g View Figure 16 ). Propodeum large (0.18 × as long as mesoscutum) (Fig. 16g View Figure 16 ). Profemur elongated (2.25 × as long as wide). Marginal vein long (1.19 × as long as postmarginal vein). Metasoma medium (0.49 × as long as body). Ovipositor rather long (0.16 × as long as metasoma) (Fig. 4g View Figure 4 ).

Redescription.

FEMALE. Colour (Figs 4g View Figure 4 , 7g View Figure 7 , 10g View Figure 10 , 13g View Figure 13 , 16g View Figure 16 ). Scape yellow, darkening apically, rest of antenna dark brown. Procoxa and profemur dark green, all other parts of legs dark brown with yellow joints and tarsi. Metasoma dark brown.

Head (Figs 7g View Figure 7 , 10g View Figure 10 ). Face completely reticulate. Head 1.58 × as wide as long. Head width 3.55 × eye distance. Malar space 0.31 × head height. Corona 0.45 × as long as eye height. POL 1.20 × OOL. Scape 2.41 × as long as pedicel. Clava 0.16 × as long as funicle. Flagellum 1.31 × as long as head width.

Mesosoma (Figs 13g View Figure 13 , 16g View Figure 16 ). Pronotum 0.95 × as long as wide. Pronotum 0.54 × as long as mesonotum. Mesonotum 1.38 × as long as mesoscutum. Mesoscutum 0.91 × as long as wide. Mesoscutellum 0.38 × as long as mesoscutum. Profemur 1.31 × as long as protibia.

Wings (Fig. 4g View Figure 4 ). Fore wing 2.65 × as long as wide. Costal cell 0.37 × as long as fore wing. Marginal vein 0.21 × as long as fore wing. Marginal vein 3.17 × as long as stigmal vein. Postmarginal vein 2.67 × as long as stigmal vein.

MALE. Unknown.

Material examined.

ASIA. China: female paratype Oodera regiae , 12.1994, det. Z.Q. Yang 1995, rest of labels in Chinese ( CNC) (ORe01) .

Biology.

Parasitic on the larvae of Xyeloborus sp. ( Curculionidae ) and Agrilus sp. ( Buprestidae ) on a walnut ( Juglans regiae ) tree (Yang, 1996).

Distribution.

China (Province: Shaanxi; Palaearctic part of China) ( Yang 1996).

Taxonomic remarks.

The species is characterised by a very short corona (measured as corona length to eye height). In all other species the corona is distinctly longer, with no diagnostically useful differences among them.

We were unable to examine the holotype. Given that the paratype we examined is from the same series as the holotype and that it perfectly matches the (short) description, we decided to include the species in our revision, diagnoses and key without examination of the primary type.

The description of O. regiae Yang, 1996 lists four characters to distinguish this species from O. formosa . First, O. regiae does not have dense hairs on the basal tergite (interpreted as the first gastral tergite), arranged circularly, while O. formosa does. This was not confirmed. The distribution of gastral hairs is identical between the examined O. regiae and specimens of O. formosa . Second, O. regiae is described to have "eyes having sparse pubescence" ( Yang 1996). However, this character is shared among all examined Oodera species. Third, O. regiae should have "not radiately striated crests on propodeum" ( Yang 1996), implying that O. formosa has radiately striated crests on the propodeum. We found the propodeal structures to be rather variable intraspecifically and decided not to use them as diagnostic characters. Fourth, "notauli not touch each other posteriorly" in O. regiae (Yang, 1996), implying that they do in O. formosa . In fact, the notauli never touch in Oodera species. In summary, the diagnostic characters for O. regiae listed in the description by Yang (1996) are not useful. However, we found other characters to differentiate the two species (see diagnoses and key).
