In females of both species the propodonotal shield is entire and in males the hysteronotal shield is entire. This new species differs from R. toxostomaas follows: in females of R.  dendrocolaptesi  sp. nov., the pygidial shield is densely punctuate on whole surface; a pair of small hysteronotal shields is present and bearing bases of setae d1; genital setae g1are situated outside the genital plate; lengths of setae siand f2are 75–80 and 100–135, respectively; in males, the aggenital plate is well developed. In females of R. toxostoma, the pygidial shield is apunctuate; the hysteronotal shields are absent; genital setae g1are situated on the genital plate; lengths of setae siand f2are 150–155 and 70–80, respectively; in males, the aggenital plate is absent.
