Epipleoneura angeloi Pessacq & Costa 2010: 55 View in CoL View Cited Treatment –61, figs. 1a–c, 2a–b, 3a–b, 4 (new species, description of male and probable female, illustration of cercus in dorsal and lateral view, epiproct in posterior view, genital ligula in ectal and lateral view, female pronotum in dorsal and lateral view, comparison with Epipleoneura williamsoni View in CoL , distribution map, type material at MNRJ). Pessacq et al. 2012: 5 (included in list of Brazilian Protoneuridae View in CoL ).
Specimens examined. 16 ♂, 1 ♀. Holotype ♂ and 10 paratype ♂, Brazil, Minas Gerais State, Chapada dos Guimarães, riacho da represinha (about 15°27’11”S, 55°44’19”W), leg. Santos, N.D. & A. Carvalho, 28 x 1983. 3 paratype ♂ 1 ♀, same data as previous but: Rio Coxipozinho (about 15°27'S, 55°44'W). 2 paratype ♂, Brazil, Goiás State, Riacho Jataí (17°52′51″S, 51°42′50″W), leg. N.D. Santos, L.F.R. Netto, & Dacio, 12 x 1982.
Diagnosis. Epipleoneura angeloi belongs, along with E. haroldoi Santos, 1964 , E. manauensis Santos, 1964 , E. spatulata Rácenis, 1960 , and E. williamsoni , to a group of species with a long, well-developed dorsal branch and dorso-ventrally flattened cercus (about as long as or longer than S10) parallel to main body axis, and a foliate and concave ventral branch ( Figs. 22 View FIGURES 22 – 24 c, 23c, 24c and 27c). This group also lacks the inner-basal branch or tooth and the apical hook in the cercus. As well as in E. manauensis and E. williamsoni , the genital ligula ( Fig. 45 View FIGURES 28 – 47 ) has a bilobate apex with a shallow medial cleft, each postero-lateral projection has a long peduncle and its apex is bent distally. With E. haroldoi and E. williamsoni it shares a similar epiproct morphology ( Figs. 23 View FIGURES 22 – 24 a–c) that is curved in lateral view with two relatively short and parallel branches widely separated at their bases.
This species is similar to E. williamsoni (contrasting characters given in parentheses); but in E. angeloi the ventral branch of the cercus is small and is separated by a narrow excavation from the upper branch, both are almost parallel and the apex of the paraproct does not surpass the level of the apex of the ventral branch (ventral branch larger and widely separated from dorsal branch, apex of paraproct surpasses level of the apex of the ventral branch in E. williamsoni ).
E. williamsoni and E. angeloi also share the presence of a small black spine close to cercus apex on inner margin ( Figs. 23 View FIGURES 22 – 24 a and 24a). Similarities of this species with E. manauensis are discussed under that species. The male of E. angeloi has the cercus dorsal branch flattened, dorsal and ventral branches separated by a narrow excavation and ventral branch small and rounded. The female posterior lobe of prothorax ( Fig. 53 View FIGURES 53 – 66 ) is erect, with a wide rounded posteriorly directed medial lobe visible in dorsal view, and two rounded lateral lobes visible in lateral view, which distinguishes it from females of all other known Epipleoneura species.
Distribution. Brazil, Mato Grosso (Chapada dos Guimarães) and Goiás (Jataí River) States (type locality Chapada dos Guimarães, riacho da represinha, about 15°27’11”S, 55°44’19”W).
