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 ).
