description: 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
