KEY TO AMERICAN GENERA OF SUBTRIBE GORYPHINA

1. First tergite without lateral triangular tooth or flange at base ................................................................................ 2

– First tergite with lateral triangular tooth or flange at base (tooth sometimes indistinct in male) .............................. 3

2. Lower tooth of mandible about half as long as upper tooth. Epomia long and strong. Fore wing with areolet small, open distally. Brachiella long, reaching almost hind wing margin. Basalpartofpropodeum(infrontofbasalcarina) verylong.— Ovipositor tip very long and slender, about 8.0 times as long as deep, its lower valve without teeth except near apex. Head usually entirely black (mandible and clypeus sometimes white). About 30 species in Neotropical region [ Scherrer, Aguiar, 2012] .................. Debilos Townes, 1966

– Lower tooth of mandible slightly shorter than upper tooth. Epomia short and weak.Areolet medium-sized, sometimes as long as portion of second recurrent vein above bulla. Brachiella sometimes absent. Basal part of propodeum (in front of basal carina) not unusually long .......................... ............................................... Hylophasma Townes, 1960

3. First tergite with spiracle near its middle ( Fig. 1 ). Clypeus with two small median teeth on lower margin ( Fig. 3 , arrow). Mesopleuron with vertical furrow extending from centre of sternaulus to mesopleural fovea ( Fig. 8 , arrow). Fore wing with areolet large, pentagonal, about 0.45 times as long as second recurrent vein and about 1.5 times as long as portion of second recurrent vein above bulla ( Fig. 10 ). Fourth tarsomeres of female ventrally slightly bilobed at apex .................................................. Tsimpision gen.n.

– First tergite with spiracle distinctly behind its middle ( Fig. 11 ). Clypeus without teeth, or with one or two small median teeth on lower margin. Mesopleuron without vertical furrow between centre of sternaulus and mesopleural fovea. Fore wing with areolet usually shorter than portion of second recurrent vein above bulla. Fourth tarsomeres of female ventrally weakly or strongly bilobed at apex ..... 4

4. Frons with median horn. — Scutellum with lateral carina present only at its basal corner. Fore wing with areolet small, about 0.7 times as long as portion of second recurrent vein above bulla. First tergite stout; its ventrolateral carinae strong and complete; median dorsal carinae absent. Second tergite with coarse punctures. Three species in Neotropical region (all records from Mexico) .............. .............................................. Listrognathus Tschek, 1870

– Frons without horn. Other characters varied ..................... 5

5. Fourth tarsomere of female deeply bilobed ventrally; front lobe at least 1.5 times as long as hind lobe. Lower margin of clypeus laterally projecting as weak or distinct triangular lobes. Apical transverse carina of propodeum without apophyses but forming sublateral weak crest. Brachiella very short or absent ..................... Loxopus Townes, 1970

– Fourth tarsomere of female weakly emarginate ventrally or with lobes subequal. Lower margin of clypeus laterally sometimes impressed but not forming triangular lobes. Apical transverse carina of propodeum often with apophyses (in female) or forming sublateral weak crest (usually in males). Brachiella short or long ..................................... 6

6. First tergite without dorsolateral and ventrolateral carinae; median dorsal carinae absent. Hind wing with brachiella present, rather long, reaching at least 0.35 distance to wing margin. Scutellum with lateral carina in its basal 0.2–0.5. Ovipositor sheath about 0.9 times as long as hind tibia ... ........................................... Diapetimorpha Viereck, 1913

– First tergite with dorsolateral carinae; ventrolateral carina strong or present at least on postpetiole. Brachiella shorter, reaching about 0.25 distance to wing margin, or entirely absent .............................................................................. 7

7. First tergite slender ( Figs 11 , 18 ), without distinct median dorsal carinae; ventrolateral carinae weak, partly obliterated. Scutellum with lateral carina at its basal 0.6–0.8. Ovipositor sheath about 0.65 times as long as hind tibia; dorsal valve at nodus not thickened, nodus very weak ( Fig. 19 ) ..................................................... Tessaloridon gen.n.

– First tergite stout, with distinct median dorsal carinae and strong ventrolateral carinae. Scutellum with lateral carina at its basal 0.2–0.6, sometimes lateral carina absent. Ovipositor sheath about as long as hind tibia; dorsal valve at nodus distinctly thickened ....... Baltazaria Townes, 1961
