Six new species of Poeciloderrhis from Brazil (Blattaria: Blaberidae) with a new record and a new combination

Abstract

In this contribution six new species of Poeciloderrhis Stål, 1874 are described: P. aureolatus sp. nov. (Holotype male in MNRJ: Brazil, Rio de Janeiro State), P. mediansclerostylatus sp. nov. (Holotype male in MNRJ: Brazil, Rio de Janeiro State), P. diamantinensis sp. nov. (Holotype male in MNRJ: Brazil, Mato Grosso State), P. itatiaiensis sp. nov. (Holotype male in MNRJ: Brazil, Rio de Janeiro State), P. vanzolinii sp. nov. (Holotype male in MNRJ: Brazil, Rio de Janeiro State), and P. penduloides sp. nov. (Holotype male in MNRJ: Brazil, Rio de Janeiro State). The genus is recorded for the first time from the state of Rondônia, Brazil based on P. diamantinensis sp. nov. A new combination is proposed for Poeciloderrhis bicolorata Rocha e Silva & Lopes, 1977 that is transferred to Epilampra Burmeister, 1838. For specific delimation, the tergal modification in the abdomen, the genital plates and their respective structures were analyzed. A key for males including all species of Poeciloderrhis is also given.
