Additional material examined: BRAZIL, Bahia, Abaíra, Cachoeira da Samambaia, Rio Catolés, Distrito de Catolés, 13º18’21,6”S, 41º51’16”W, 1♀, 4/XI/2013, L.S. Carvalho & M.B. da Silva (UFMG 15071).

Diagnosis. Males of E. mauru sp. nov. are easily recognized by their tibia to possess a black dorsal retrolateral basal apophysis with constriction at the base and prolaterally directed tip and short RTA in waveform directed retrolaterally. Females have very conspicuous reniform spermathecae ventrally, vulva with three visible chambers within each of them (Figs 36, 37)

Etymology. The specific epithet is a noun taken in apposition and is in reference to Mauru, a fictional character in Waku Waku Seven, game from SUNSOFT for Neo Geo, which is the non-threatening guardian of Lost Forest. The shape of spermathecae looks like his eye pupils.
