Remarks. In addition to the specimens collected in this study, we also examined 3 paratypes of this species from Álvaro de Carvalho, São Paulo, Brazil, several other specimens identified as N. idaeus  from different parts of Brazil and one specimen from Paraguay. The females collected in this study and the paratype females all have a lightly sclerotized posterior margin of the sternal shield. Additionally, all of these specimens have st 3 inserted off the sternal shield. The position of st 3 was not mentioned in the text of the original description of N. idaeus  , but in the original illustration st 3 is shown inserted on the sternal shield. This led Ueckermann, Moraes and Zannou (in Zannou et al. 2006) to describe Neoseiulus tridenticus  from Kenya as a new species, due to st 3 being inserted off the sternal shield. Considering the great similarity between these two nominal species and the fact that N. idaeus  was released in large numbers in Kenya in 1985 and 1989 (Yaninek et al. 1993) for the control of the cassava green mite, Mononychellus tanajoa (Bondar)  , we conclude that N. tridenticus  is a junior synonym of N. idaeus  .
