Description.
Female. Fore wing length 3.0 mm.
Face at level of antennal sockets as wide as high; head smooth and polished, face with punctures; eyes not setose; dorsal ridge of face in between antennal sockets without a median prominence; face in profile straight, except just before antennal sockets impressed; edge of clypeus straight, antennal sockets on a shelf; malar space with distinct subocular sulcus which is bent towards occiput; maxillary palp reaching to beyond fore coxa. In dorsal view, head posteriorly concave; temples short; lateral ocellus separated from eye by a distance 1.3 times longer than its maximum diameter; POL 1.3 times as long as diameter of lateral ocellus, lacking ocellar-ocular grooves. Minimum distance between antennal sockets about 0.7 × diameter of socket; antenna comparatively short and thick, with 24 flagellomeres (25 in paratype) which gradually shortening apically; first flagellomere 1.5 times as long as wide and about 0.4 times as long as scape; scape nearly parallel-sided.
Mesosoma smooth and polished except postero-ventral corner of pronotum with short striae, mesoscutum with indicated notauli; in profile, scutellum weakly convex, metapleuron somewhat convex; propodeum with coriaceous microsculpture and with complete posterior transverse carina, lateromedian longitudinal carinae indistinct basally, spiracle small.
Legs all slightly flattened, broad; coxae and femora polished, tibiae and tarsi coriaceous-granulate; hind femur 3.1 times as long as high, hind tibia 3.6 times as long as apically wide; tibiae dorsally with spine-like setae; spurs curved apically.
Wings not particularly narrow, fore wing with areolet closed but 3rs-m weak, areolet longer than high, vein 2rs-m shorter than 3rs-m, 2m-cu meeting areolet at apical 0.6, vein Rs nearly straight; nervellus intercepted slightly below middle.
First tergite 2.0 times as long as posteriorly wide, in dorsal view, slightly wider at spiracles; coriaceous, with weak lateromedian longitudinal carinae, with transverse impressions originating at about middle of tergite, sloping posteriorly, not meeting centrally. Second tergite 1.2 times as long as posteriorly wide; coriaceous, with shallow transverse impressions originating at about middle of tergite, sloping anteriorly and posteriorly, not meeting clearly centrally; anterior thyridia small, contrastingly coloured. Third tergite coriaceous; remaining tergites smooth and polished; fourth tergite with coriaceous microsculpture antero-medially. Ovipositor slightly upcurved, thin, as long as hind femur, without dorsal notch; ovipositor sheath narrow, pointed, with setae longer than ovipositor sheath width and curved backwards, sparser basally.
Body setose except eyes, pronotum, mesopleuron, metapleuron; setae on propodeum, anterior tergites and posterior sides of coxae very few.
Blackish brown except mouthparts and malar space pale, antenna dull yellow ventrally, infuscate over entire dorsal side. Clypeus apically and dorsal ridge of upper face between antennae narrowly yellowish, frontal orbits with small yellowish marks close to antennal sockets; sternites creamy, fore and mid legs and hind trochanters and trochantellus yellowish. Hind coxae brown in basal 2/3, hind femur brownish, except for more light basal third. Tergites 3 and 4 with light brown apical margin.
Male. Unknown.
Biology.
Hosts unknown.
Etymology.
Named from the Latin cauda (tail) after the unusually long ovipositor as long as the hind femur.
Comparison.
This is a distinctive species on account of the very long, thin, slightly upcurved ovipositor, which is as long as the hind femur (Fig. 3A View Figure 3 ).
