sp. n.
A. Hypopygium; B. ApeX of fore tibia.
Description
. Male.
Head.
Brown. Eye bridge 4 facets wide. Antenna brown; 4th flagellomere with l/w index of 2.0, with hairs as long as the diameter of the basal node, necks rather long, about 1/3 of the length of the basal node. Palpus 3-segmented, basal segment with one bristle.
Thorax
. Brown. Scutum with rather short hairs and some more robust lateral bristles; scutellum with 2 stronger marginal bristles. Postpronotum bare. Wing pale; R1 = 2/3 R; R5 without ventral macrotrichia; C somewhat longer than 1/2 w; y = x, without macrotrichia; posterior veins without macrotrichia. Haltere short and darkened. Legs yellowish brown; fore tibia with an irregular row of bristles at the inner apex, not distinctly bordered; middle and hind tibia with two equal spurs, much longer than the diameter of the apex. Claws toothless.
Abdomen
. Brown. Hypopygium brown, sparsely haired; gonocoxite shorter than gonostylus, with a long, strong bristle on the ventral apex, with short sparse hairs on the inner ventral margin; gonostylus slightly curved and concave on the inner side, apically narrowed and with two short bristle-like subapical spines within equally long hairs; on the inner side below the middle with a long and robust curved whiplash hair-like spine on a large base. Tegmen strongly bulging laterally. Aedeagus short. Body length:
1.5 mm
.
Comments
. The new species is characteriZed by a narrow gonostylus with 2 short rod-like apical spines within equally long hairs and the strongly curved whiplash hair-like spine on the inner side near the base.
Keilbachia adstrictatula
is very similar to
K. indigena
Mohrig, 2004
from Papua New Guinea. It differs by a narrower apex of the gonostylus with two rod-like spines within the hairs, a larger base of the whiplash hair-like spine, a longer aedeagus, a hairless space at the ventral base of the hypopygium and a more row-like arrangement of bristles on the apex of the fore tibia.
