Remarks. Individuals of Indiani gaspar sp. nov. were collected in limestone caves and has some typical troglomorphic traits of troglobite species, such as loss or reduction of eyes and weak pigmentation (Christiansen 2012). However, as observed by Rodrigues et al. (2018), these characteristics also are observed in epigean species of prodidominae and only the appendage elongation seems to be an important morphological indicative to determine species troglobites in subfamily. In addition, the lack of samplings in epigean habitats does not allow us to determine of the troglobitic status in I. gaspar sp.nov.
Type Material. Male holotype from Brazil, Minas Gerais, Prados, Cave HOL_0020 (44°03’59”W 21°11’06”S), 13–16 March 2017, Eq. Spelayon leg., deposited in IBSP 201864. Paratypes: Brazil, Minas Gerais, Prados, Cave HOL_0001 (44°03’52”W 21°10’57”S), 17–19 November 2014, Eq. Spelayon leg., 1 female (IBSP 201863).
Etymology. The specific name is a noun in apposition referring to character “Casper, the friendly ghost” that in Portuguese is known as “Gasparzinho”, once the species has weak pigmentation like a ghost.
