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
