Previous records. Argentina, Brazil, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, Montenegro, Nicaragua, Paraguay, Portugal, Trinidad and Venezuela.

Remarks. Euseius concordis is morphologically very similar to E. caseariae ( De Leon). Based on the redescription of the former species by McMurtry (1983) and on the original description of the latter, the major difference between them refers to the longer z 4 in the former. However, in specimens of E. concordis collected from areas next to its type locality in northern Argentina (our unpublished observations), from Guatemala (McMurtry 1983) and Brazil ( Noronha & Moraes 2002) the length of z4 is quite variable. For this reason, we suspect that E. caseariae is a junior synonym of E. concordis . In some of the specimens collected in Quillabamba — Macamango and in Amayabamba, the length of seta s4 is intermediate between that of the holotypes of E. concordis and E. caseariae ; in others, length of s4 is similar to that of the holotype of E. concordis . In this work, we considered all o those specimens to be E. concordis .

Lambayeque: Chiclayo — Callanca (06°50'51''S, 79°48'57''W), 6-VIII-2006, on Cestrum auriculatum (2Ψ, 2 immatures), on Val le s ia glabra (Apocynaceae) (5Ψ), on Solanum melongena (2Ψ), on C. auriculatum (3Ψ); Chiclayo — Mochumi (06°32'23''S, 79°51'29''W), 6-VIII-2006, on R. communis (10Ψ, 5ɗ).

Previous records. Peru — Lima ( El-Banhawy 1979).

Remarks. The position of seta R1 varies in this species. After observing 75 specimens, it was noticed that in 36% of them both setae R1 are inserted on the dorsal shield; in 40% of specimens, seta R1 of one side is inserted off the dorsal shield; in the remaining 24% of specimens, both setae R1 are inserted off the dorsal shield. The paratype collected on C. papaya has the seta R1 of one side inserted off the dorsal shield, the other paratype collected on Acalypha sp. has both setae R1 inserted on the dorsal shield. This species is similar to E. concordis , but differs by the shorter macroseta of tarsus IV and by having, in most cases, at least one seta R1 inserted on the dorsal shield, because of the lateral expansion of the dorsal shield posterior to base of s4. This species further differs from E. concordis by having margin of dorsal shield in this region with distinct angle.
