Ceranisus udnamtak
sp. n.
Figs 40, 41
Etymology: The specific name is a reversed spelling of the
type
locality, Katmandu.
Diagnosis: This species is easily recognisable from all other described species of
Ceranisus
by the unique combination of the following morphological characters: F1 of female antenna much longer than broad, a little longer than F2; forewing with a very long postmarginal vein (much longer than stigmal vein) and a distinct bare area along posterior margin behind base of marginal vein, demarcated anteriorly by a sinuate row of setae; and a yellow metasoma. It is somewhat similar to female of
C. menes
with a completely yellow metasoma, from which female of
C. udnamtak
can be easily distinguished using the characters indicated in the key above.
Description: Female (
holotype
). Head and mesosoma brown, metasoma and appendages yellow or very light brown.
Antenna (
Fig. 40
) with scape slender, 5.25 x as long as wide; pedicel a little longer than F1; funicle long, F1 much longer than wide, a little longer than F2 and with 1 sensillum, F2 slightly wider than F1 and also with 1 sensillum; clava slightly longer than funicle, 2.0 x as long as wide, its distal segment about 1.5 x longer than basal claval segment, both with several sensilla.
Figs 40, 41.
Ceranisus udnamtak
sp. n.
, female (holotype): (40) antenna, (41) forewing. Scale lines = 0.1 mm.
Mesosoma almost as long as metasoma; pronotum, mesoscutum, scutellum, and axillae with faint cellulate sculpture; midlobe of mesoscutum with 2 pairs of setae. Forewing (
Fig. 41
) about 2.5 x as long as wide; longest marginal setae 1/4 maximal width of forewing; disc hyaline, with numerous, short setae, more or less uniformly setose behind and beyond base of marginal vein except for a conspicuous bare area along posterior margin behind base of marginal vein, demarcated anteriorly by a notably sinuate line of setae; postmarginal vein very long, much longer than stigmal vein. Coxae faintly sculptured.
Ovipositor occupying 0.65 length of gaster, not exserted; ovipositor length/metatibia length ratio about 1.2:1.
Measurements (n=1,
holotype
). Body: 916.Antenna: scape: 127; pedicel: 55; F1: 42; F2: 38; clava: 85. Forewing: 736/291; longest marginal seta: 70. Ovipositor: 270.
