Abstract

This paper reports on the Phytoseiidae from an Araucaria forest in the State of Rio Grande do Sul, describing four new species, namely Transeius kroeffis n. sp., Typhlodromalus araucariae n. sp., Typhlodromips pompeui n. sp. and Typhlodromips salvadorii n. sp.. Iphiseiodes moraesi Ferla & Silva, Neoseiulus tunus (DeLeon), Typhlodromips japi Lofego, Demite & Feres, Typhlodromips pallinii Gonçalves, Silva & Ferla, Typhloseiopsis dorsoreticulatus Lofego, Demite & Feres are reported for the first time from this type of habitat in Rio Grande do Sul state, Brazil.

The tribes Kampimodromini Kolodochka and Typhlodromipsini Chant and McMurtry (Mesostigmata: Phytoseiidae) in the Serra do Espinhaço, Brazil, with a key to the Brazilian species of Typhlodromips De Leon

“…The studied females are morphologically similar to those of the species description collected in São Paulo, and the setal measurements fit the original description and data provided later by Gonçalves et al (2015) and Rocha et al (2015) for specimens from Rio Grande do Sul.…”

“…The most similar described species is T. pompeui Gonçalves & Ferla from southern Brazil. Typhlodromips pompeui differs from the new species for having: i) a bigger size, with the dorsal shield 25% longer; ii) dorsal setae not placed on tubercles; iii) setae j3 and Z4 45% shorter; setae S5 70% shorter; setae Z5 23% longer; iv) three pairs of dorsal solenostomes instead of seven in the new species, v) seven setae on genu II instead of eight; vi) preanal pores crescentic instead of punctiform; vii) posterior metapodal shield elongated, no suboval (Gonçalves et al 2015).…”
