Female imago and nymph. Unknown. Etymology. The name botafora is a reference to the type locality, the Bota Fora waterfall. Noun in apposition. Distribution. Brazil: Piauí State. Type material. Holotype: Ô imago Brazil, Piauí State, Piripiri municipality, Cachoeira do Bota Fora, S4°12′51.1′′, W41°40′01.7′′, 162m, 14.x.2017, Lima, R. C.L. col. (UFVB). Comments. Miroculis (Miroculis) botafora sp. nov. is morphologically similar to Miroculis fazzariensis Costa & Mariano 2013, mainly because both have a longitudinal groove connecting to the opening of gonopore. In M. (M.) botafora sp. nov., the gonopore groove is present from the apical half of each lobe, while in M. fazzariensis it is restricted to the apex of the penes. Besides, the penes length of the new species is 1.8× the forceps segment I, opposed 0.8 to 1.0× in M. fazzariensis.

Life cycle association. Rearing. Biology. The nymphs were collected inhabiting leaves in a stream with about 6 m wide, moderate flow, and under an open canopy. Etymology. In Brazil, quilombolas are communities of descendants of enslaved Africans who have maintained cultural, religious and subsistence traditions for a few centuries. The new species was found in a stream from the quilombola community S„o Benedito dos Colocados. Noun in apposition. Distribution. Brazil: Maranh„o State. Type material. Holotype: Ô imago (reared, exuviae and male imago preserved in alcohol), Brazil, Maranhão State, Codó municipality, Rio Saco, S4°31″53.9″, W43°54′49.5″, 52m, 22.viii.2020, Nascimento, S.R.S. col. (INPAEPH000037). Paratypes: one Ô imago, same data as holotype (INPA-EPH000038); three Ô nymph, same data as holotype (INPA-EPH000039). Comments. Male imagos of Miroculis (Miroculis) quilombola sp. nov. are morphologically similar to M. (M.) fittkaui, by sharing similar posteromedian margin of styliger plate expanded with a shallow medial excavation, inner basal margin of forceps segment I corrugated, length and apex excavated of penes (or hooked). However, the male imago of the new species differs by having a forewing less wide basally and with membrane hyaline; penes with ten irregular spines basally in lateral view (Fig. 10C), opposed to basally with shallow crenulation in M. (M.) fittkaui (Fig. 58 in Savage 1983); and having the inner margin of forceps segment I without distomedial projection (Fig. 9D). Nymphs of M. (M.) quilombola sp. nov. resemble those of M. (M.) azevedoi sp. nov. because of tarsal claws with subapical denticle larger than the remaining denticles and anterior margin of labrum angular. However, M. (M.) quilombola sp. nov. has the color pattern of the abdomen without marks along the posterior margin on terga and gills with trachea unbranched (Fig. 11D), opposed to M. (M.) azevedoi sp. nov. that presents dark brown marks on abdominal terga I–VIII and gills with trachea branched., Published as part of Rodrigues, Jackson A. O., Nascimento, Stênio R.

Life cycle association. Rearing. Biology. The nymphs were collected inhabiting leaves in a shallow stream with moderate flow and about 1 m wide. Etymology. We name this species in honor of Carlos Augusto Silva de Azevêdo for his friendship and important contribution to the knowledge about aquatic insects in Maranh„o State. Distribution. Brazil: Maranh„o State. Type Material. Holotype: Ô imago (reared, exuviae and male imago preserved in alcohol), Brazil, Maranhão State, Caxias municipality, Riacho Planaçucar, S4°54′24.8′′, W43°21′45.2′′, 71m, 25.x.2019, Nascimento, S.R.S. col. (INPA-EPH000034). Paratypes: two Ô subimagos, same data as holotype (INPA-EPH000036); one Ô nymph, same data as holotype (INPA-EPH000035). Comments. Miroculis (Miroculis) azevedoi sp. nov. is morphologically similar to Miroculis (Miroculis) botafora sp. nov. by sharing penes long and wider at base and by having a styliger plate expanded, with posterior margin concave. However, the male imago of M. (M.) azevedoi sp. nov. differs by having a penes apically flattened and rounded in lateral view, with a minute spine medially in ventral view, opposed to the penes presenting a gonopore almost completely fused, with ventral sulcus in the apical half of each lobe and apically curved upward in M. (M.) botafora sp. nov. Besides, in M. (M.) azevedoi sp. nov. the forceps segment I present a constriction at apex and there is no subdistomedial projection on the inner margin. Nymphs of M. (M.) azevedoi sp. nov. resemble those of M. (Atroari) nebulosus Savage, 1987 and M. yulieae Raimundi & Salles, 2017 because of the similarity of their branched gills and tarsal claws with subapical denticle larger than the remaining denticles. However, they differ from each other especially by the color pattern of abdomen and shape of anterolateral margin of labrum: angular in M. (M.) azevedoi sp. nov., rounded in M. nebulosus, and slightly angular in M. yulieae.

The males imagos sampled in Piau�� State (Fig. 11A���D) were caught up in the evening at the riparian environment under a dense canopy cover. Instead of a well-developed bridge between the stalks of the compound eyes, as reported in the literature or based on examined material from Bahia state (Fig. 11E) and Colombia (Fig. 11F), some of these imagos from Piaui state (n = 4) present only a small protuberance. According to Peters & Dom��nguez (2001), the presence of these protuberances is a subimaginal character, which in imagos develop to the bridge characteristic of the species. In order to complement the description of the species, herein we report the absence of this bridge in some of the examined imagos (Fig. 11C���D). Distribution.

Remarks. Pigments in forewings are usual in Hagenulopsis species and it may occur on cross veins, longitudinal veins, on the membrane or surrounding longitudinal and cross vein (Fig. 4). The males of H. perere sp. nov. are somewhat similar to males of H. diptera sharing with them the general color, the upper portion of compound eye meeting dorsally, and the brown bands on middle and apex of hind femur. However, the males of H. perere sp. nov. can be differentiated from the males of H. diptera by the remarkable brown clouds surrounding the cross veins located between longitudinal veins C to RP 1 and by a brown spot at the midlength on the outer surface of the middle femur. In addition, mature nymphs and females of H. perere sp. nov. can also be distinguished from all other species by the presence of clouds surrounding the cross veins between longitudinal veins C and RP 1., Published as part of Campos, Rog��rio, Rodrigues, Jackson A.

BRAZIL, Espírito Santo, Santa Teresa, Reserva Biológica Augusto Ruschi, Córrego Bragacho, (19°52′2.53″S, 40°33′34.27″W; 830 m a.s.l), 19.xii.2017, D-net Salles FF & Costa V. leg., 3 N, 2 ♀♀ (UFVB); same data as for preceding except for: 30.ix.2017, 3 ♂♂ (INPA); Minas Gerais, Araponga, Serra do Brigadeiro, Vale das Luas (20°39′37″S, 42°26′55″W; 990 m a.s.l), 24.i.2014, Entomological net, Salles FF. leg., 2 ♂♂ (MZUSP). Remarks. Pigments in forewings are usual in Hagenulopsis species and it may occur on cross veins, longitudinal veins, on the membrane or surrounding longitudinal and cross vein (Fig. 4). The males of H. perere sp. nov. are somewhat similar to males of H. diptera sharing with them the general color, the upper portion of compound eye meeting dorsally, and the brown bands on middle and apex of hind femur. However, the males of H. perere sp. nov. can be differentiated from the males of H. diptera by the remarkable brown clouds surrounding the cross veins located between longitudinal veins C to RP 1 and by a brown spot at the midlength on the outer surface of the middle femur. In addition, mature nymphs and females of H. perere sp. nov. can also be distinguished from all other species by the presence of clouds surrounding the cross veins between longitudinal veins C and RP 1.

- Abstract
Caenidae is a globally widespread family, inhabiting a variety of aquatic habitats. In South America, only 35 species are recognized, maybe as a consequence of the few studies until the first decade of the 21st century. Despite recent advances, large portions of Brazil, such as Rondnia State, are still characterized by Linnean and Wallacean shortfalls. Rondnia is an area predicted to have high mayfly richness, but with no record of Caenidae. From this perspective, the objective of this study is to provide the first access to primary biodiversity data of Caenidae (Ephemeroptera) from Rondnia. As result, we report five species (Brasilocaenis elidioi, Brasilocaenis irmleri, Caenis chamie, Caenis fittkaui, Latineosus sigillatus) and describe a new species based on all life stages (Caenis urupa sp. nov.).
