Hind wing: vein 1M 1.06–1.26× length of vein cu-a; vein 1M 0.72–0.94× length of vein r-m; propleuron and metapleuron rugulose; propodeum rugose; T1 costate, with costae slightly convergent; ovipositor 1.62–1.82× first tergite length.

Males. Similar to females except: body length 3.38–3.84 mm; head width 1.17–1.31× head height; head height 1.60–1.70× eye height; face maximum width 1.16–1.24× its minimum width; face minimum width 1.00–1.04× clypeus width; ocellar-ocular distance 1.25× ocellar diameter. Fore wing: vein r 0.41–0.57× length of vein 3 Rsa. Hind wing: vein 1M 0.95–0.97× length of vein r-m; scape and pedicel dark brow infused with yellow.

Comments. This species is most similar to M. laphygmae Viereck with a complete occipital carina, antenna with at least 27 flagellomeres, notauli not distinct, dorsope absent, borders of T1 joined along half of the segment, and tarsal claw with a large lobe. Meteorus strigatus can be distinguished by having ocellar-ocular distance 1.33– 1.58× ocellar diameter, mesonotal lobes and most of mesopleuron black and metasoma with black patches.

In the key to Neotropical species of Meteorus ( Aguirre et al. 2015) , M. strigatus will key to couplet 27 near M. luteus Jones , but can be distinguished by having mesopleuron black with a yellow spot near precoxal sulcus, malar space length 0.40–0.55× mandible width basally, and metasoma with black markings on T2 and T3.

Distribution. Meteorus strigatus occurs in Ribeirão Grande and Salesópolis in the state of São Paulo, Itamonte in the state of Minas Gerais, and Itatiaia in the state of Rio de Janeiro, Brazil ( Fig. 41 ).

Etymology. This species is named in reference to the strigate sculpturing present on its face and hind coxa.
