Key to species of mycetophilus -group of Apanteles from China

1. Body stout; T1 shorter ( Fig. 5 f), broad basally and relatively dull or rugose; pterostigma white................................................................................................... A. artustigma Liu & Chen , sp. n.

- Body slender; T1 longer to very long ( Fig. 8 d), relatively narrow basally and mostly polished; pterostigma brown......... 2

2. Ovipositor sheath markedly falcate towards apex............................................ A. odites Nixon, 1965

- Ovipositor sheath narrow and of even size, not falcate......................................................... 3

3. T1 very long, almost 2× as long as its basal width; penultimate antennomere of antenna long, at least 1.6× longer than wide. 4

- T1 relatively shorter (e.g. Fig. 6 e); penultimate antennomere of antenna transverse to subcubic........................ 5

4. Ocelli relatively large ( Fig. 7 a), distance between fore and hind ocelli shorter than diameter of an ocellus; head as wide as mesosoma; vein r 1.4× longer than vein 2-SR, both veins indistinctly angled at their meeting.................................................................................................... A. magnioculus Liu & Chen , sp. n.

- Ocelli relatively small ( Fig. 10 f), distance between fore and hind ocelli not shorter than diameter of an ocellus; head distinctly wider than mesosoma; vein r nearly as long as (or faintly shorter than) vein 2-SR, both veins distinctly angled at their meeting.......................................................................... A. thoracartus Liu & Chen , sp. n.

5. Legs bright reddish brown; scape, pedicel yellow; T3 1.6× as long as T2; T2 straight apically................................................................................................... A. hainanensis Liu & Chen , sp. n.

- Legs dark brown; scape, pedicel brown; T3 2.3× as long as T2; T2 curved into T3........... A. sparsus Liu & Chen , sp. n.
