Amputoearinus fernandezi Sharkey ( Fig. 2 d)

Diagnosis: This species can be distinguished from all other species of Amputoearinus by the following characters; forewing infuscate with yellow patch in basal quarter and yellow band in apical 3rd quarter; propodeum with distinct carinae.

Description: Holotype Ψ

Body length: 6.0 (5.8–6.1) mm. Color: body yellow except melanic as follows: flagellomeres, pedicel, scape laterally, mid and hind tibia distally, midtarsus distally, hind tarsus, ovipositor sheaths; posterior three terga with black patches laterally; forewing infuscate with yellow patch in basal quarter and yellow band in apical 3rd quarter (cf. Fig. 4 e). Head: antenna with 37 (37–40) flagellomeres Mesosoma: scutellar sulcus lacking longitudinal carina (cf. Fig. 6 d); projection of propleuron blunt, not dorsoventrally flattened, and without ridges (cf. Fig. 6 f); median areola of mesosoma well defined with sharp carinae laterally and posteriorly (cf. Fig. 7 c); propodeum mostly smooth with pair of short carinae fused anteriorly to appear as an inverted v-shape (cf. Fig. 5 g); margin between metepimeron and metepisternum smooth, lacking transverse carinae (cf. Fig. 7 b); mesopleural suture with transverse carinae; carina bordering subpronope posteriorly, extending to anterior margin of pronotum (cf. Fig. 6a ); length of midtibial spur 0.4mm; length of midbasitarsomere 0.5mm; midtibia with 3–4 pegs at midlength, lacking pegs apically; hind tibia with 5 pegs apically; forewing length 6.0mm Metasoma: median syntergite 2+3 length 1.4mm, width 1.2mm.

Variation: Most specimens have a smooth propodeum with sculpture reduced to a small protuberance anteromedially.
