Psyttoma van Achterberg & Li gen. n. Figures 1 13

Etymology.

The name is a combination of the generic names Psyttalia Walker and Phaedrotoma Foerster, 1862, because it combines features of both genera. Gender: feminine.

Type species.

Opius latilabris Chen & Weng, 2005.

Diagnosis.

Hypopygium of female distinctly acute apically and about 0.3 times as long as metasoma; labrum slanted backwards, leaving a large space below clypeus ( Fig. 9 ); veins 2-SR+R and SC+R1 of hind wing of male strongly widened ( Fig. 13 ); precoxal sulcus smooth; hind femur 2-3 times as long as wide ( Fig. 11 ); hind tibia without carinula basally; scutellum convex medially and depressed medio-posteriorly, distinctly protruding above level of mesoscutum ( Fig. 5 ); propodeum without median carina or areola; second metasomal segment 1.2 times longer than third tergite ( Fig. 4 ); spiracle of second tergite distinctly removed from apex of first tergite ( Fig. 4 ).

Notes.

The genus will run in the key to world genera of Opiinae by Wharton (1997) to the genera Psyttalia Walker and Opius Wesmael (part with normal mandible; = Phaedrotoma ). Because of the sharp pointed hypopygium it seems closer to Psyttalia , but it does not fit in any one of the genera and differs in having a medio-posterior depression of the mesoscutum, the second metasomal tergite longer than the third tergite, the precoxal sulcus smooth, the scutellum protruding dorsally, the hind wing narrowed and vein m-cu of the hind wing present as a faintly pigmented trace. The new genus can be separated from both genera as follows:

1	Scutellum distinctly protruding above level of mesoscutum ( Fig. 5 ); hypopygium of ♀ distinctly acute apically and about 0.3 times as long as metasoma ( Fig. 7 ) and hind wing comparatively narrow ( Figs 12, 13 ); hind femur very robust, 2-3 times as long as wide ( Fig. 11 ); labrum slanted backwards, leaving a large space below clypeus ( Fig. 9 ); medio-anterior veins of hind wing of male strongly widened ( Fig. 13 )	Psyttoma gen. n.
-	Scutellum at level of mesoscutum; hypopygium of ♀ variable, if distinctly acute apically and about 0.3 times as long as metasoma then hind wing moderately wide and hind femur slender, 4-5 times as long as wide; labrum normal, without large space below clypeus; medio-anterior veins of hind wing of male narrow	Psyttalia Walker and Phaedrotoma Foerster
