……continued on the next Page ……continued on the next Page Euseius concordis .— Denmark & Muma, 1973: 264; Moraes et al., 2004: 64; Demite et al., 2015.

Euseius flechtmanni Denmark & Muma, 1970: 223 (synonymy by Moraes et al., 1982: 18).

Euseius caseariae De Leon, 1967 : 21; Moraes & Mesa, 1988: 80; McMurtry & Moraes, 1989: 186. (new synonymy).

Specimens examined. E. concordis : holotype and specimens from the type locality (previously reported by Guanilo et al., 2008b), E. flechtmanni : 20 specimens from the type locality: Universidad Nacional de Asunción - Facultad de Ciencias Agrarias on Citrus sp., collected in February, 2013.

An examination of the specimens collected in the type locality of E. concordis (already reported by Guanilo et al., 2008b) and in the type locality of E. flechtmanni , showed them to be very similar to what was reported in their original descriptions and subsequent redescriptions ( Chant & Baker, 1965; McMurtry, 1983; Moraes & McMurtry, 1983; Guanilo et al., 2008b). These observations led us to confirm the synonymy of E. concordis and E. flechtmanni proposed by Moraes et al. (1982).

McMurtry & Moraes (1989) considered E. caseariae to be distinguishable from E. concordis by having shorter j3, z4 and s4. Setal measurements of specimens identified as E. concordis , from its type locality ( Guanilo et al., 2008b) and from Brazil ( Lopes, 2015), showed a wide variation in the lengths of some setae, especially j1, j3, z2, z4, Z5 and s4. A comparison of the measurements provided by those authors with those of the original description of E. caseariae and of our measurements of a paratype of that species led to the conclusion that it is a junior synonym of E. concordis .
