Two new species of Tydeidae (Acari: Prostigmata), records of species of this family and Triophtydeidae from Brazil

Abstract

Two new species of Tydeidae are described, Brachytydeus lorenzatus sp. nov. and Quasitydeus feresi sp. nov. Brachytydeus lorenzatus sp. nov. differs from B. aegyptiaca (Rasmy [amp]amp; El Bagoury, 1979) by having a reticulated area on the region of f1 and f2 , dorsal setae smooth, solenidion (I shorter than or equal to the width of tarsus I, most setae on dorsal shield shorter than the length between their bases and setae d forked distally. The new species is distinguished from B. scutatus Silva, Rocha [amp]amp; Ferla, 2013 by having a slightly reticulate area on the aspidosoma, near setae bo , all dorsal setae slender and club-shaped. Quasitydeus feresi sp. nov. differs from the only other species of the genus, Q. ricensis (Baker, 1970), by having all dorsal setae simple and serrated, similar in shape. Eleven tydeoid species are reported also from several plants native to the state of Rio Grande do Sul, Brazil. This is the second species of Brachytydeus Thor, 1931 described from and the second species described for Quasitydeus Ka[amp]#378;mierski, 1996.
