description: Key to genera of Scolebythidae
Based on the key of Engel and Grimaldi (2007), we set up a new key to genera of Scolebythidae to include the new genus Mirabythus Cai, Shih et Ren, gen. nov.
1. Vein R1 of fore wing present, either fusing apically or nearly meeting Rs ......................................... 2
- Vein R1 of fore wing absent, and thereby not fusing with Rs apically............................................ 6
2. R1 and Rs fusing; pronotal collar absent.................................................................. 3
- R1 and Rs not meeting; pronotal collar present...................................... Boreobythus Engel et Grimaldi
3. Cell 1R1 not enlarged, shorter in length than cell 2R1; frons without median prominence between antennal toruli.......... 4
- Cell 1R1 elongate, longer than cell 2R1; frons with median prominence between antennal toruli............ Ycaploca Nagy
4. Crossvein r-m absent, cell 1R1 longer than cell 1M in length, Cu distad 1m-cu nebulous or absent..................... 5
- Crossvein r-m present, cell 1R1 nearly equal to cell 1M in length, Cu distad 1m-cu tubular........... Mirabythus gen. nov.
5. Occipital carina present; malar space short, less than one-half basal mandibular width; cell 2R1 apex situated along anterior wing margin; S5 without special patches of setae............................................... Scolebythus Evans
- Occipital carina absent; malar space well over one-half basal mandibular width; cell 2R1 apex arched away from anterior wing margin; S5 with two patches of appressed, dense setae...................................... Clystopsenella Kieffer
6. Apical portion of Rs tubular; fore wing with or without closed cell 1R1 .......................................... 7
- Apical portion of Rs nebulous; fore wing without closed cell 1R1 ............................................... 9
7. Fore wing without closed cell 1R1; dorsal-facing surface of pronotum greatly reduced, much smaller than mesoscutum.... 8
- Fore wing with closed cell 1R1; dorsalfacing surface of pronotum enlarged, larger than mesoscutum..................................................................................... Libanobythus Prentice et Poinar
8. Minute wasps (less than 2 mm in total length), with more typical scolebythid habitus; face without impressed medial line, without depressions lateral to antennal toruli; parapsidal lines faint but present; ocelli positioned just above upper tangent of compound eyes; one metatibial spur................................................ Uliobythus Engel et Grimaldi
- Small wasps (ca. 2.6 mm total length), with bethylid-like habitus; face with strong medial line impressed from between anten- nal toruli to upper tangent of compound eyes, with gentle depressions lateral to antennal toruli; parapsidal lines absent; ocelli positioned far behind upper tangent of compound eyes; two metatibial spurs............... Zapenesia Engel et Grimaldi
9. Frontal prominence present; occipital carina present; metafemur not flattened....................... Pristapenesia Brues
- Frontal prominence absent; occipital carina absent; metafemur flattened.......... Eobythus Lacau, Nel et Villemant, 2000
