Figs 23–24 , 27 Diagnosis . Males are similar to those of C. armasi by having a moderately long embolus and a median apophysis with a small tooth on the concave mesal margin, but can be distinguished by lacking a retrobasal cymbial horn and the smaller RTA ( Figs 23C–E , 24B–D ) (with retrobasal horn and shorter median apophysis in C. armasi , Fig. 20D–F ). Types . Male holotype from Parque Nacional de Itatiaia ( 22°22′31″S , 44°39′44″W ) [-22.37528, -44.66222], Itatiaia , Rio de Janeiro , Brazil , I–III.2015 , L. Vieira & J. Louzada coll., deposited in IBSP 258687 . Etymology . The specific name is a noun in apposition taken from the type locality. Description . Male ( holotype ). Carapace orange to reddish brown.
