Redescription
Female.
Length, 2.0 mm. Body dark brown to black; head with bluish shine, face above with a violet cross-band; inter-torular area up to mouth margin purple; malar space bluish in upper half, violet in lower half. Antenna with scape and pedicel dark brown; F1–4 yellow, F1 with slightly pale brown infuscation basally (in cleared and slidemounted antenna, F1–4 appear white); clava with first and third segments pale brown, second segment brownish yellow. Mesosoma with pronotum with bluish shine; mesoscutum purple, anteriorly and laterally with some greenish shine, but in some lights appears largely greenish blue; axillae dull bronzy with bluish green shine; scutellum mainly purple, with sides and apex bluish; tegula dark brown; metanotum and propodeum black; prepectus purple, posteriorly white; mesopleuron dark brown. Fore wing with hyaline and infuscated areas as in
Fig. 2
. Hind wing hyaline. Fore leg: coxa dark brown in basal half, white in apical half; trochanter white; femur yellow with a pale brown streak along ventral margin; tibia yellow with a narrow brown streak along ventral margin, tarsus brownish yellow. Mid leg: coxa dark brown; trochanter brownish yellow; femur brownish yellow with a dark brown streak along ventral margin (one-third the width of femur); tibia white with a brown streak in basal half of ventral margin; spur and tarsal segments 1–4 white, 5th segment pale brown. Hind leg: coxa nearly black; trochanter pale brown, femur black except base narrowly pale brown; tibia black except white apical fifth; tarsal segments 1–4 white, 5th brown. Gaster with T1 bluish, other tergites dark brown with at most dark violet shine; exserted part of ovipositor sheath dark brown.
Head. Frontovertex width 0.3× head width; posterior ocellus very close to eye margin; POL slightly less than OCL (7.5:8); frontovertex with raised reticulate sculpture, setae small and silvery white, those on upper part of occiput brown [The pair of long, scale-like setae at vertexo-occipital margin lost]. Antenna (
Fig. 1
) with scape 4.15× as long as broad; pedicel longer than F1; F1–3 each slightly longer than broad, F4 quadrate; clava shorter than funicle.
Mesosoma with pronotum triangular, nearly as long as mesoscutum, and 2× as broad as long; mesoscutum 2× as broad as long; scutellum 1.35× as broad as long; pronotum with slightly raised, irregular reticulations; mesoscutum with shallow reticulations; scutellum with raised reticulations, the cells very small, with sides and apex smooth [Scutellum with the sub-apical pair of long, scale-like setae lost.]; setae sparse, silvery white. Fore wing 2.75× as long as broad; width of ray II broader than width of hyaline window between ray II and ray III; rays III and IV not distinctly separated by a hyaline window, but appear as a single large apical infuscation; ray V as broad as ray II (
Fig. 2
).

Comments.
The above redescription is largely based on the original description and figures given by
Hayat & Veenakumari (2014)
, and study of the slide-mounted antenna and fore wing of the
holotype
. The only character in which this species is similar to
C. shikokuensis
(
Tachikawa, 1956
)
and
C. sudhiri
is in having the fore wing clearly less than 3× as long as broad and apically broadly rounded. Otherwise,
C. albifuniculata
differs from both species by the characters given in the key.
