Diagnosis
.
Although
Narendran (1989)
recorded a female of this species from Philippines, no detailed description was provided. Hence the female of this species is described here in detail.
Brachymeria kamijoi
comes near
Brachymeria fiskei
Habu in the key to species by
Habu (1960)
, but differs from that species in having: 1) the hind tibia black at base except a small yellow spot before base (in
Brachymeria fiskei
hind tibia widely yellowish at base) and 2) the scutellum uniformly and densely pitted (in
Brachymeria fiskei
scutellum with a narrow impunctate smooth space medially). This species also resembles
Brachymeria nephantidis
Gahan in the general colour of the body, but differs from it in having: 1) the scutellum emarginate at its apex (in
Brachymeria nephantidis
scutellum apex evenly curved and entire); and 2) metasoma subglobose (in
Brachymeria nephantidis
metasoma ovate).
Description
(female from Chu Yang Sin N.P.). ♀, length of body 5.0-5.3 mm.
Colour. Black; eye and ocelli grayish yellow; tegula whitish yellow; all coxae black; all femora black with apices yellow; fore and mid tibiae yellow with black band at middle; hind tibia black with subbasal and apical yellow patches or spots; all tarsi whitish yellow; telotarsi dark brown. Pubescence silvery.
Head. Head densely pubescent on face and gena; scrobe separated from anterior ocellus by rugose-reticulate area; POL 2.5
x
OOL; each posterior ocellus separated from anterior ocellus by a distance shorter than OOL; pre and post-orbital carina present; MS 0.25
x
eye height in profile; eye height 1.7
x
eye length in profile; antenna with scape not reaching anterior ocellus. Relative L:W of antennal segments:scape = 13:4; pedicel = 2:4; F1 = 4:5; F2 = 3:5; F3 = 3:4; F4 = 3. 5:7; F5 = 4:6; F6 = 4:6; F7 = 4:6; clava = 8:6.
Mesosoma. Mesosoma completely pitted dorsally, interstices narrow and carinate; mesoscutum and scutellum convex; apex of scutellum distinctly emarginated with a row of dense pubescence on all around margins of scutellum.
Wings. Fore wing with relative length of veins: SMV = 45; MV = 30; PMV = 8; STV = 4.
Legs. Hind coxa without an inner basal tooth, outer ventral margin with 13 irregular sized teeth.
Metasoma. Metasoma globose or subglobose, shorter than mesosoma (25:31); T1 reaching half-length of metasoma, smooth and shiny; T2 minutely and densely punctate, punctures becoming faint near dorso-basal area; T2 with fairly dense pubescence laterally; T3 to apex of metasoma pubescent; T6 perpendicular, with 3-4 cross rows of irregular pits; epipygium in dorso-posterior view shorter than half length of T6.
Male. Similar to ♀ except for stouter antenna.
Host.
Unknown.
Distribution.
Vietnam (new record), Japan, Philippines (
Narendran 1989
