Amputoearinus erudio Lindsay and Sharkey sp.n. ( Fig. 2 c)

Diagnosis: This species can be distinguished from all other species of Amputoearinus by the following character; mesopleural suture smooth, lacking transverse carinae.

Description: Holotype Ψ

Body length: 8.7 (8.8)mm. Color: body yellow except black and brown as follows: antenna, head, propleuron, forecoxa, forefemur ventrally, midcoxa, midfemur, all black; midtibia brown apically, midtarsomeres brown; hind coxa black; hind femur black ventrally, brown dorsally, hind tibia, last tergite of metasoma; ovipositor sheaths black; forewing banded from base yellow, infuscate, yellow, infuscate; foremargin yellow throughout. Head: antenna with 45 (40) flagellomeres. Mesosoma: scutellar sulcus lacking longitudinal carina (cf. Fig. 6 d); projection of propleuron acute, lacking ridges (cf. Fig. 6 e); median areola of mesosoma not depressed medially, lacking sharp carinae laterally and posteriorly (cf. Fig. 7 d); propodeum completely smooth (cf. Fig. 5 d); margin between metepimeron and metepisternum smooth, lacking transverse carinae (cf. Fig. 7 b); mesopleural suture smooth, lacking transverse carinae; carina bordering subpronope posteriorly, not extending to anterior margin of pronotum (cf. Fig. 6 b); length of midtibial spur 0.6mm; length of midbasitarsomere 0.9mm; midtibia with 3–5 pegs at midlength, lacking pegs apically; hind tibia with 2–5 pegs apically; forewing length 8.7mm. Metasoma: median syntergite 2+3 length 1.6mm, width 1.6mm.

Variation: the lone male specimen of this species differs in the following coloration: body yellow except melanic as follows: head, antenna, propleuron, forefemur ventrally, midfemur; midtibia distally, hind femur black with yellow patch basally; hind tibia and tarsus, metasoma dark brown to black throughout with posterior tip of metasoma black; apex of forewing infuscate.

Etymology: the Latin erudio , for smooth, because the propodeum of this species is smooth, without sculpture.
