Amputoearinus niger Lindsay and Sharkey sp.n. ( Figs. 3 c, 5a, 5h, 6a)

Diagnosis: This species can be distinguished from all other species of Amputoearinus by the following character; median areola of propodeum complete.

Description: Holotype Ψ

Body length: 7.0 (6.2–9.6) mm. Color: body black except: propodeum, metasoma yellow, foretarsus off-white, first tarsal segment of midleg white, posterior surface of hind coxa orange, hind tibia orange medially; forewing weakly infuscate basally, deeply infuscate apically ( Fig. 5 a). Head: antenna with 41 (40–43) flagellomeres. Mesosoma: longitudinal carina of scutellar sulcus present (cf. Fig. 6 c); projection of propleuron acute (cf. Fig. 6 e); median areola of mesosoma well defined with sharp carinae laterally and posteriorly (cf. Fig. 7 c); median areola of propodeum rugulose and complete ( Fig. 5 h); mesopleural suture with transverse carinae throughout its length; margin between metepimeron and metepisternum with transverse carinae (cf. Fig. 7a ); carina bordering subpronope posteriorly, extending to anterior margin of pronotum (cf. Fig. 6a ); length of midtibial spur 0.6mm, length of midbasitarsomere 0.6mm; midtibia with 0–1 peg(s) at midlength, 0–1 peg apically; hind tibia with 2–3 pegs apically; forewing length 5.8 (5.6–7.8)mm. Metasoma: median syntergite 2+3, length 1.2mm, width 1.4mm.

Variation: Three paratypes differ considerably; female from Estación Cacao in Costa Rica: body color black except for: hind femur, hind tibia orange, black apically; propodeum and metasoma orange. Female from Venezuela: body black except: forefemur and midfemur brown dorsally, black ventrally; foretarsus brown; apex of first midtarsomere off-white; hind femur orange, hind tibia orange basally, black apically; median area of propodeum orange, first three metasomal terga dark orange, fourth to sixth terga orange, posterior two terga black. Male from Costa Rica: body color black except; foretarsus off white, basal midtarsomere off-white basally; hind femur orange, hind tibia orange, black distally, hind tarsomeres black; propodeum orange, metasoma orange.

Etymology: from the Latin niger , meaning black, dark, because of the mostly black bodies of this species.
