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 View 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 View Figure 6 (e)); notauli shallowly to distinctly impressed anteriorly ( Figure 4 View Figure 4 (e)); scutellar sulcus indistinct to distinct, with ( Figure 6 View Figure 6 (g)) or without ( Figure 2 View Figure 2 (e)) crenulation; scutellum smooth to weakly punctate, posterior depressions often medium-sized to large ( Figure 4 View Figure 4 (g)), rarely obsolescent, touching ( Figure 7 View Figure 7 (e)) to widely removed from each other ( Figure 6 View Figure 6 (g)); propodeum with a strong median carina ( Figure 2 View Figure 2 (f)), if rarely largely absent then antero-medially rugose; vein r obsolescent to distinct ( Figure 1 View Figure 1 (g)); vein 1-R1 absent or distinctly vein-like or triangular ( Figure 2 View Figure 2 (g)), short of reaching the length of pterostigma ( Figure 3 View 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 View Figure 1 (k)); T2 short ( Figure 1 View Figure 1 (k)) to very long at base ( Figure 2 View Figure 2 (k)); T3 often entirely longitudinally striate ( Figure 1 View 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 View 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.
