( Figure 2 View Figure 2 )
Diagnosis
This new species and Typhloseiopsis funiculatus DeLeon, 1965 are unique in the genus by having the ventrianal shield completely formed. However, T. dorsoreticulatus differs from T. funiculatus by having the dorsal shield completely reticulated and setae Z4 and Z5 strongly serrate, whereas T. funiculatus has a smooth dorsal shield for the most part and Z4 and Z5 also smooth.
Specimens examined
Holotype female, from Piper sp. ( Piperaceae ) leaves, 24 July 2008, Serra do Japí, Jundiaí, State of São Paulo, Brazil, 23 ◦ 11 ′ S, 46 ◦ 52 ′ W, P.R. Demite and J.C. de Souza colls. Paratypes: two females and one male, from same host, date and collectors as the holotype; one female and one male, from Croton floribundus Spreng. (Euphorbiaceae) leaves, 12 September 2008, V. de O. Lima and C. Vieira colls. All paratypes from same locality as the holotype.
