Paecilaema batman, a new species of Brazilian troglophilous harvestman that exhibits a remarkable color patches variation (Opiliones: Cosmetidae)

Abstract

A new species of harvestman, Paecilaema batman, from Brazilian limestone caves of the state of Goiás, is described, and a remarkable intraspecific color patch variation is discussed. Paecilaema batman sp. nov. differs from other species of the genus by the following combination of features: chelicera similar in both sexes; prosoma without color patches; typical color patches on area I; and area III with two high spines. The new species is considered troglophilous.
