Generic rediagnosis
Antenna with flagellomeres longer than wide or as long as wide, sometimes with acute tooth ventro-apically on 5 th flagellomere (Figure 1 (d)); head wider than long in dorsal view; face more or less convex medially with or without medial longitudinal carina anteriorly; frons smooth or granulate, convex medially, rarely with mid longitudinal carina; vertex smooth; mesoscutum smooth to shallowly punctate, sometimes with longitudinal carina laterally or raised carinae behind tegula (Figure 6 (e)); notauli shallowly to distinctly impressed anteriorly (Figure 4 (e)); scutellar sulcus indistinct to distinct, with (Figure 6 (g)) or without (Figure 2 (e)) crenulation; scutellum smooth to weakly punctate, posterior depressions often medium-sized to large (Figure 4 (g)), rarely obsolescent, touching (Figure 7 (e)) to widely removed from each other (Figure 6 (g)); propodeum with a strong median carina (Figure 2 (f)), if rarely largely absent then antero-medially rugose; vein r obsolescent to distinct (Figure 1 (g)); vein 1-R1 absent or distinctly vein-like or triangular (Figure 2 (g)), short of reaching the length of pterostigma (Figure 3 (f)); tarsal claw with or without basal lobe; T1 indistinctly to distinctly constricted to apex posterior to its apical widest part (Figure 1 (k)); T2 short (Figure 1 (k)) to very long at base (Figure 2 (k)); T3 often entirely longitudinally striate (Figure 1 (k)); ovipositor sheath often around (0.5 to 1.5 ×) the length of hind basitartus, with long hairs more on apical part (Figure 3 (e)).
Biology
Koinobiont endoparasitoids of Microlepidoptera (Nepticulidae, Acanthopteroctetidae, Gracillariidae, Heliozelidae, Tineidae, Cosmopterigidae, Tischeriidae, Lyonetiidae) and Diptera (Agromyzidae) (Ranjith et al. 2019).
Distribution
Afrotropical, Nearctic, Neotropical, Oceanic, Oriental and Palaearctic (Yu et al. 2016; Ghramh et al. 2019; Liu and Polaszek 2024).
Notes
Centistidea can be separated from the other two genera of Miracinae combining presence of a longitudinal carina or rugosity medially connected to more or less developed costulae on propodeum with more developed notauli for practical use.
