Amputoearinus surinen Lindsay and Sharkey sp.n. ( Fig. 4 c)

Diagnosis: This species can be distinguished from all other species of Amputoearinus by the following characters; scutellar sulcus lacking longitudinal carina, projection of propleuron blunt, median areola of mesosoma not depressed medially and lacking sharp carinae laterally and posteriorly, propodeum completely smooth, lacking carinae.

Description: Holotype Ψ

Body length: 6.6 (6.3) mm. Color: orange except melanic as follows: scape, pedicel, antenna with light brown tips, head posteriorly, propleuron, midtibia apically, hind coxa apically, hind femur, hind tibia basally and apically, hind tarsus; metasoma light brown except for posterior three terga black; forewing infuscate with yellow patch in first quarter and yellow band in apical 3rd quarter (cf. Fig. 4 e). Head: antenna with 36 (40) flagellomeres. Mesosoma: scutellar sulcus lacking longitudinal carina (cf. Fig. 6 d); projection of propleuron blunt (cf. Fig. 6 f); median areola of mesosoma not depressed medially and lacking sharp carinae laterally and posteriorly (cf. Fig. 7 d); propodeal sculpture completely smooth without carinae (cf. Fig. 5 d); mesopleural suture with transverse carinae along its length; margin between metepimeron and metepisternum smooth, lacking transverse carinae (cf. Fig. 7 b); 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 4 pegs at midlength, lacking pegs apically; hind tibia with 5–6 pegs apically; forewing length 6.6 (6.2)mm. Metasoma: median syntergite 2+3 length 1.4mm, width 1.2mm.

Male: Unknown

Variation: paratype female orange except as follows: black patch laterally on scape and pedicel, antenna with light brown tips, midtarsus brown, hindtibia black apically, hind tarsomeres black, metasoma darker orange than mesosoma.

Etymology: named after the Surinen Indians, the earliest known inhabitants of Suriname.
