Amputoearinus variegatus Lindsay and Sharkey sp.n. ( Figs. 4 d, 6a)

Diagnosis: This species can be distinguished from all other species of Amputoearinus by the following characters; forewing yellow with infuscate band apically; margin between metepimeron and metepisternum with transverse carinae; carina bordering subpronope posteriorly, extending to anterior margin of pronotum.

Description: Holotype Ψ

Body length: 7.7 (6.3–8.1) mm. Color: body yellow except melanic as follows: head, antenna, propleuron, forecoxa, forefemur, foretibia, foretarsus, midcoxa distally, midfemur distally, midtibia, midtarsus, hind coxa anterodistally, hind trochanter, hind tibia with patch distally, hind tarsus; forewing yellow with infuscate band apically (cf. Fig. 4 f). Head: antenna with 43 (40–44) flagellomeres. Mesosoma: scutellar sulcus lacking longitudinal carina (cf. Fig. 6 d); projection of propleuron blunt and lacking ridges (cf. Fig. 6 f); median areola of mesosoma slightly depressed medially with sharp carinae laterally and posteriorly (cf. Fig. 7 c); propodeal sculpture reduced to small protuberance anteromedially (cf. Fig. 5 f); mesopleural suture with transverse carinae along its length; margin between metepimeron and metepisternum with 4 transverse carinae (cf. Fig. 7 b); carina bordering subpronope posteriorly, extending to anterior margin of pronotum ( Fig. 6a ); length of midtibial spur 0.6mm, length of midbasitarsomere 0.7mm; midtibia with 4 pegs at midlength, 1 peg apically; hind tibia with 6–8 pegs apically; forewing length 6.8 (5.9–7.1)mm. Metasoma: median syntergite 2+3 length 1.4mm, width 1.2mm.

Male: Unknown

Variation: Majority of paratypes with: body orange except melanic as follows: antenna, black patch posterior to eye, forefemur apically, foretibia, midfemur apically, midtibia except yellow patch distally, tarsi apically; hind trochanter, hind tibia apically, hind tarsus; ovipositor sheaths. Female paratype from Province Puntarenas differs as follows: body orange except for melanic as follows: antenna, black patch posterior to eye, foretibia, forefemur apically, midtibia, midfemur apically, hind trochanter, hind tibia apically, hind tarsus; mesopleural suture with strong transverse carinae ventrally, one strong carina medially, weak carinae dorsally.

Etymology: from the Latin variegatus meaning of different sorts, due to the color variation of this species.
