Diagnosis. Ipsiura myops most closely resembles I. spiculella Bohart and I. tropicalis Bohart. It can be readily distinguished from these and other Ipsiura species by the following combination of characters: T3 with four obtuse distal teeth, without basolateral whitish spot (whitish spot present in I. spiculella and I. tropicalis), neither prepit swelling (sloping gently in I. tropicalis); large S2 spots (medium-sized in I. tropicalis). Additionally, the shape of aedeagus lobes is diagnostic for I. myops .

Female description. Body (Fig. 129). Length: 6.8 mm. Coloration: head green blue; F1 brownish green; mesosoma metallic green, with purple blue highlights on dorsum, particularly on pronotum and mesoscutum; metasoma metallic green, with purplish blue transverse stripes on dorsum of T1 and T2; T3 without lateral whitish spot; wing membrane light brown, with brown veins; femora and tibiae greenish; tarsi brown, hind basitarsus green. Head: TFC forming an incomplete arc, widely interrupted medially (Fig. 130); F1 longer than broad, 1.2× as long as F2; scapal basin covered with silvery pubescence. Mesosoma: fore femur without flattened area or ventral tooth-like projection on outer surface of distal margin, diameter of distal area about one-half diameter of proximal area; fore wing with short M distal to discoidal cell, R1 shorter than stigma (as in Fig. 190); dorsal surface of pronotum wider than head; lower lateral pronotal surface irregularly punctate anteriorly, with indistinct posterior area delimited by faint transverse ridge; metanotum rounded, without differentiated surface; mesopleural lower posterior margin carinate, with small indistinc tooth-like projections. Metasoma: T3 with four obtuse distal teeth (Fig. 131), pit row with large and deep foveae, prepit swelling absent; S2 spots large, nearly reaching each other medially (Fig. 132). Punctation: definite punctation at all body; tiny punctures on outer surface of fore femur; dorsum of T3 with definite, deep punctures; largest punctures on dorsum of T1 and metanotum.

Male. Same as female, except for the characteristic shape of S2 spots as shown in Fig. 132. Genital capsule (Fig. 133): aedeagus longer than gonostylus and cuspis; gonostylus longer than cuspis; digitus length subequal to cuspis, strongly clavate apically; gonostylus and cuspis setose apically.

Variation. Body length 6.2–7.1 mm.

Hosts. Specimens reared from nests of Ancistrocerus flavomarginatus (Brèthes), Trypoxylon agamemnon (Richards) and T. lactitarse (Saussure), (Tayane Buggenhagen, personal communication).

Distribution. Argentina (Corrientes, Jujuy, Salta, Tucumán); Brazil (MG, PR, SC, SP); Uruguay (Tacuarembó) (Fig. 134).
