Diagnosis. Ipsiura leucocheiloides most closely resembles I. bohartiana Lucena sp. nov. and I. nigriventer Bohart. It is readily distinguished from these and other Ipsiura species by the following combination of characters: T3 with four obtuse distal teeth (sharp in I. bohartiana and I. nigriventer ), with narrow lateral whitish spot (spot absent in I. bohartiana sp. nov.), with strongly convex prepit swelling (sloping gently in I. bohartiana and I. nigriventer ); lower posterior margin of mesopleuron with two strong close together tooth-like projections (well-separated in I. bohartiana sp. nov. and I. nigriventer ); and medium-sized S2 spots (unusual large in I. nigriventer ). Additionally, the aedeagus lobes elaborate and unusual long digitus (longer than the cuspis) are diagnostic for I. leucocheiloides ( Fig. 111 ).

Female description. Body ( Fig. 107 ). Length: 8.2 mm. Coloration: head predominantly bluish green; F1 greenish brown; mesosoma metallic bluish green, with bluish purple transverse stripe on dorsum of pronotum, mesoscutum with broad purple highlights; metasoma metallic bluish green, with distinct transverse purplish stripes on dorsum of T1 and T2; T3 with lateral whitish spot; wing membrane brown, with brown veins; femora and tibiae greenish; tarsi brown, basitarsi brownish green. Head: TFC forming an incomplete arc, somewhat interrupted medially ( Fig. 108 ); F1 longer than broad, about 1.3× as long as F2; scapal basin covered with silvery pubescence laterally, with narrow polished stripe medially. Mesosoma: fore femur with distinct flattened area on outer surface of distal margin, diameter of distal area subequal to diameter of proximal area; fore wing with short M distal to discoidal cell, R1 shorter than stigma (as in Fig. 190 ), medial cell with sparse setae only distally; dorsal surface of pronotum wider than head; lower lateral pronotal surface irregularly punctate anteriorly, with distinct posterior area delimited by faint transverse ridge; metanotum rounded, without differentiated surface; mesopleural lower posterior margin strongly carinate with two close together tooth-like projections. Metasoma: T3 with four obtuse distal teeth ( Fig. 109 ), pit row indicated by shallow, long foveae, with strongly convex prepit swelling; S2 spots medium-size to large, nearly reaching each other medially ( Fig. 110 ). Punctation: fore femur with shallow, sparse punctures on outer surface; largest punctures on T1, mesopleuron and metanotum.

Male. Same as female except for the characteristic shape of S2 spots as shown in Fig. 110 , the broad dark band occupying much of the dorsum of metasoma and mesosoma, and conspicuous long sivery setae ventrally on anterior legs, prosternum and gena. Genital capsule ( Fig. 111 ): aedeagus lobes elaborate, sinuous, acute apically, slightly longer than gonostylus and cuspis; cuspis as long as gonostylus; digitus longer than cuspis, broad apically, clavate; gonostylus and cuspis setose apically.

Variation. Body length 7.7–8.3 mm.

Hosts. Unknown.

Distribution. Bolivia (Santa Cruz); Brazil (AM, ES, PA); Peru (Madre de Dios, Maynas, Ucayali) ( Fig. 112 ).
