B0254349F221FFFAFF60C29BFC47D345.taxon	etymology	Etymology. The specific name atuberculatus refers to the absence of tubercles on dorsal shield.	en	Narita, João Paulo Z., De Moraes, Gilberto J.

B0254349F221FFFAFF60C29BFC47D345.taxon	discussion	Remarks. Females and males of E. atuberculatus differ from all other Epicriopsis species in the following way: absence of tubercles on dorsal shield; presence of rows of spine-like structures in the central region of the dorsal shield; adult females with 25 pairs and adult males with 27 pairs of dorsal shield setae (21 pairs in males of E. mirabilis Willmann, 1956 and 19 pairs in males of E. palustris Karg, 1971 a and E. rivus Karg, 1971 b). This is the first species of this genus described from the American continent. Cheliceral membranous lobes have been shown in the description of most Epicriopsis species. In addition to the new species here described, cheliceral lobes have been shown in the original descriptions (Karg, 1971 a, Karg, 1971 b; Ishikawa, 1972; Livshitz & Mitrofanov, 1975; Kandil, 1978; Halliday, 1997; Ma, 2002) or redescriptions (Bregetova, 1977) of E. baloghi Kandil, E. horridus (Kramer, 1876), E. hungarica Kandil, E. jilinensis Ma, E. langei Livshitz & Mitrofanov, E. palustris Karg, 1971 a, E. stellata Ishikawa, E. suedus Karg, 1971 b and E. walteri Halliday. Nothing was mentioned in this regard in the description or redescriptions of E. mirabilis Willmann, 1956 and E. rivus Karg, 1971 b. However, differences concerning the cheliceral digit to which these structures are attached seem to occur, according to the literature. In E. walteri, a membranous lobe is shown attached to the fixed digit; in E. baloghi, E. hungarica, E. jilinensis and E. suedus it is shown attached to the movable digit, while in E. atuberculatus n. sp., E. langei and E. stellata (apparently also in E. horridus and E. palustris) membranous lobes are shown attached to both cheliceral digits. It is not known whether the lobes on the distinct digits are homologous. The rounded lobes of the new species here described seem different in shape from those in most other Epicriopsis species – distally pointed or slightly rounded. Variation in lobe shape have also been observed among species of other ameroseiid genera, including the pollen feeding Afrocypholaelaps, Hattena and Neocypholaelaps (Elsen, 1972 a; Elsen 1972 b; Halliday, 1997; Narita et al., 2011; Narita et al., 2013 a). In part, the difference could be due to the fact that the lobes are not sclerotised (Narita et al., 2013 a). Evans (1963) suggested the Epicriopsis species to be fungivorous. The presence of spores of undetermined fungi adherent to the idiosoma of the new species here described supports that assumption. A correlation between the presence or absence of cheliceral lobes, and their shape, with feeding habits does not seem straightforward, as discussed by Narita et al. (2013 a). Lobes attached to both digits apparently have not been mentioned or illustrated in other ameroseiid genera; in those, lobes have apparently not been reported attached to the movable digit.	en	Narita, João Paulo Z., De Moraes, Gilberto J.
