Diagnosis:
Meteorus artocercus
can be distinguished from similar species by its longer flagellomeres, the colour of the pterostigma and the length of the ovipositor sheaths. In Huddleston’s key
M. artocercus
runs to
M. cinctellus
but
M. artocercus
has longer antennal articles than
M. cinctellus
, the ovipositor is shorter (1.6–2.0 times petiolar tergum in the former, and 2.5–3.0 times in the latter), and the pterostigma is pale (dark brown except for the basal third in the latter).
M. tenellus
is another similar species but this species has a longer ovipositor (2.0–4.0 times petiolar tergum) and a postfurcal m-cu vein of the forewing (antefurcal in
M. artocercus
).
