Amputoearinus matamata Sharkey ( Fig. 3 b, 5g)

Diagnosis: This species can be distinguished from all other species of Amputoearinus by the following characters; median areola of mesosoma depressed medially with sharp carinae laterally and posteriorly.

Description: Holotype Ψ

Body length: 7.1 (7.1–7.4) mm. Color: body black except: fore and midlegs pale yellow except apical tarsomeres black; hind femur and basal hind tibia orange, propodeum orange, metasoma orange except for posterior four segments; forewing banded from base, yellow, black, yellow, black; foremargin yellow (cf. Fig. 5 b) Head: antenna with 43 (43–45) flagellomeres. Mesosoma: scutellar sulcus lacking longitudinal carinae (cf. Fig. 6 d); projection of propleuron acute, dorsoventrally flattened, with weak smooth ridges ventrolaterally (cf. Fig. 6 e); median areola of mesosoma well defined with sharp carinae laterally and posteriorly (cf. Fig. 7 c); propodeum with pair of short carinae fused anteriorly to appear as an inverted v-shape ( Fig. 5 g); mesopleural suture with transverse carinae throughout its length; margin between metepimeron and metepisternum smooth with very reduced transverse carinae (cf. Fig. 7 b); length of midtibial spur, 0.6mm, length of midbasitarsomere, 0.6mm; midtibia lacking pegs at midlength, 1 peg apically; hind tibia with 3 pegs apically; forewing length 7.5mm. Metasoma: median syntergite 2+3, length 1.6mm, width 1.2mm.

Variation: Paratype male from Brazil has ventral portions of the mesopleuron and hind coxa yellow; propodeal sculpture greatly reduced. Female paratypes from Colombia have propodeal sculpture greatly reduced.
