Female holotypefrom Blumenau, Santa Catarina, Brazil,  MNRJ1366, not located. World Spider Catalog, 2016.  Note.  Hermacha iricolor Mello-Leitão, 1923is here transferred to  Rachiasas the original description mentions the following features: almost glabrous carapace; labium almost as long as wide; maxillae with small area of few basal cuspules, with long and curved setae on ventral side that covering the cuspules ( Mello-Leitão, 1923). These features agree those of  Rachias, as proposed by Goloboff (1995). The holotypeof  R. iricolor( Mello-Leitão, 1923)  comb. nov.has not been located, and no specimens were found in zoological collections. Three expeditions were carried out by the first author in different altitudinal gradients ( 150–936 masl) at the typelocality and also by other researchers with pitfall traps (see Lucas et al., 2006: 52). However, no specimens have been collected. 1457229110 MNRJ Brazil Blumenau 16 451 MNRJ 1366 1 Santa Catarina holotype
