Key to the species of Ceranisus , females

1 Clava 3-segmented (at least on one of the antennae, best seen in slide-mounted specimens) .......................................................................... russelli (Crawford)

– Clava 2-segmented........................................................................................... 2

2(1) Ovipositor markedly exserted beyond apex of gaster (by about 1/3 of its total length, Fig. 38 ) .................................................................. barsoomensis sp. n.

– Ovipositor not exserted or only slightly exserted ............................................ 3

3(2) Forewing disc with a distinct semi-oval bare area at posterior margin behind base of marginal vein, demarcated anteriorly by a sinuate line of setae (i.e., cubital setal line, as in Fig. 41 ) ........................................................................ 4

– Forewing disc either without such bare area or, if a narrow bare area present along posterior margin behind base of marginal vein, it is demarcated anteriorly by a more or less straight cubital setal line (as in Figs 43 , 48 ) ........................ 6

4(3) Gaster completely dark brown or black ................................. planitianus Erdös

– At least base of gaster yellow or light brown .................................................. 5

5(4) F1 a little shorter or at most subequal to F2; postmarginal vein of forewing at most as long as stigmal vein, usually a little shorter ................ menes (Walker)

– F1 a little longer than F2; postmarginal vein of forewing much longer than stigmal vein ......................................................................................... udnamtak sp. n.

6(3) Forewing fringe very short, longest marginal setae less than 1/10 maximal width of forewing ( Fig. 43 ).................................................................. votetoda sp. n.

– Forewing fringe relatively longer, longest marginal setae at least 1/5 maximal width of forewing ............................................................................................ 7

7(6) Base of gaster yellow to light brown ............................................................... 8

– Base of gaster brown to dark brown or almost black ...................................... 9

8(7) Femora pale, yellow, or light brown ................................ americensis (Girault)

– Femora dark brown ........................................................ nigrifemora De Santis

9(7) Vertexal suture straight or a little sinuate (rounded) ...................................... 10

– Vertexal suture distinctly angulate (broadly Y-shaped) ....... femoratus (Gahan)

10(9) Basal claval segment longer than distal segment ....... antalyacus S. Triapitsyn

– Basal claval segment shorter than or at most subequal to distal segment ..... 11

11(10) Head and mesosoma dorsally notably reticulate, with well-pronounced dark green metallic luster [scape of male antenna not swollen, about 3.6 x as long as wide] .............................................................................................. lepidotus Graham

– Head and mesosoma dorsally almost smooth, at most with faint cellulate sculpturing (sometimes more obvious on mesoscutum) and slight greenish metallic luster [scape of male antenna notably swollen, less than 2.5 x as long as wide] .............................................................................................................. 12

12(11) Forewing relatively broader (length/width ratio about 2.4:1) [scape of male antenna markedly swollen, 1.8–1.9 x as long as wide] ..................................... .......................................................................... hoddlei S. Triapitsyn & Morse

– Forewing relatively narrower (length/width ratio 2.8–3.0:1) ........................ 13

13(12) Scape relatively shorter (length/width ratio 4–5:1) [scape of male antenna strongly swollen, 1.4–1.7 x as long as wide] ...................................... pacuvius (Walker)

– Scape relatively longer (length/width ratio about 7:1) [scape of male antenna moderately swollen, about 2.1 x as long as wide] ............................................. ................................................................... loomansi S. Triapitsyn & Headrick
