Oodera Westwood, 1874

Diagnosis.

Both sexes. Comparatively large-bodied (3.6-17 mm). Parascrobal area of head raised and with crest-like structure (= corona) (Fig. 1 View Figure 1 ). Pronotum long and in dorsal view separated from mesothorax by distinct constriction, semicircularly strigulate (Figs 11 View Figure 11 - 13 View Figure 13 ). Mesonotum with mesoscutum and mesoscutellar-axillar complex fused, without flexible, transverse transscutal articulation; mesoscutum with notauli V-like sulcate and extending to base of mesoscutellum; axillae strongly advanced laterally (Figs 11 View Figure 11 - 13 View Figure 13 ). Mesothorax ventrally with membranous region anterior to each mesocoxa, enabling mesocoxae to rotate anteriorly. Profemur enlarged (Figs 2 View Figure 2 - 4 View Figure 4 ) and ventrally with comb of small teeth and strong black bristles.

Female. Always with exserted part of ovipositor visible in dorsal view (Figs 2 View Figure 2 - 4 View Figure 4 ).

Description.

For a detailed description of the genus see Gibson (2003). Only few characters given there need to be redescribed based on the material examined in this study:

Mesosoma. Pronotum in dorsal view appearing somewhat pentagonal or almost circular. Mesoscutellum sculpture variable dorsally, always with longitudinally strigose parts, with smoother, coriaceous apical rim distinguished by furrow or carina.

Wings. Postmarginal vein slightly shorter to slightly longer than marginal vein.

Metasoma. Length of ovipositor sheaths varying from less than 10% of metasoma length to 110% of metasoma length.

Note that some of the characters given by Gibson (2003) were not studied for all species because they were not visible in some specimens, including types, specifically ventral views of mesosoma.

Key to Oodera species

Note: If combinations of characters are given, connected with and and separated by comma (not semicolon), then all characters have to be present; in the alternative path at least one of the characters has to be different.
