Holotype: BRAZIL ♂; ROraima,AltO AlEgrE, FlOrEsta NaciOnal DE ROraima, RiO Mucajaí; 02°56´18.05″N / 61°37´27.28″ W; 20.XII.2017 – 05.I.2018, MalaisE trap., BOlDrini, R. cOl. Paratype: ♂, SamE Data as holotype. Discussion. Simothraulopsis rainori sp. nov. has morphological similarities with S. demerara and S. sabalo, sharing characteristics such as the shape of the penis lobes and having a mid-sized, spine-like telopenis on penis lobes. Imagos of S. rainori sp. nov., however, can be distinguished from them by the abdominal terga color (terga II–VII with anterior and anterolateral margins whitish in S. pacaraima, and terga II–V with anterior and anterolateral margins whitish S. inequalis), and by the spine-like telopenis being ventrally directed with apex bent outward (anteriorly projected in other two species), ventral region of penis lobes with a well-marked sclerotized region and laterally swollen and protruding on the inner margin.Published as part of Boldrini, Rafael, Lima, Lucas Ramos Costa, Oliveira, Ismael Barreto De, Boldrini, Bianca Maira De Paiva Ottoni & Salles, Frederico Falcão, 2022, Two new species of Simothraulopsis Demoulin, 1966 (Ephemeroptera: Leptophlebiidae) from Roraima State, northern Brazil, pp. 279-286 in Zootaxa 5213 (3) on pages 281-285, DOI: 10.11646/zootaxa.5213.3.5, http://zenodo.org/record/735998

Holotype: Female nymph (antennae broken), BRAZIL, Rondônia, Ribeirão, Rio Madeira, 10 ° 13 ' 54.5 "S / 65 ° 17 '08"W, 6.vi. 2004, Hamada, N. leg (INPA). Paratype: One male imature nymph mounted on slides, BRAZIL, Rondônia, Iata, Rio Madeira, 10 ° 35 ' 46.58 ''S / 65 ° 23 '00.96''W, 22.viii. 2012, Boldrini, R., Fernandes, A.S. leg (PPGBT). Comments. Corinnella thomasi sp. nov. is easily distinguished from C. eximia by the shape of the labrum, with the distomedial emargination clearly discernible in C. eximia versus shallow in C. thomasi sp. nov.; by the shape of tarsal claws, with only the first denticle distinctly longer in C. eximia versus the first and last denticles distinctly longer in C. thomasi sp. nov.; by the shape of spines on the posterior margins of terga, being pointed in C. eximia and rounded in C. thomasi sp. nov. The rounded spines found on the posterior margins of terga can be visualized using a microscope with phase contrast.When Dominique et al. (2005) described the genus Corinnella (as Corinna), they stated that the tarsal claws were unique among Baetidae. Later, Nieto (2010), while performing a phylogenetic analysis of South American Baetidae, considered that the tarsal claws of Corinnella were spatulate, such as in the genus Camelobaetidius. Based on the new species, we agree with Nieto (2010) regarding the type of tarsal claws. Despite this similarity, Corinnella presents a series of characteristics that distinguishes it from the genus Camelobaetidius, such as: absence of the dorsal arc of setae on the labrum; presence of many long, fine, simple setae on outer margin of labial palp; and presence of a row of few spine-like setae along patella-tibial suture.Published as part of Boldrini, R., Salles, F.

Fries (1908: 57) and to P. dusenii Krapovickas (1977: 313); specimens from different herbaria were sometimes identified as the first and sometimes as the later. The mericarps of P. salmonea are usually muticous (apiculate in a few specimens), somewhat smaller than those of P. guerkeana, usually without acute tubercles on each side of the median nerve, which is wide, compressed and rugose. The mericarps of P. guerkeana are always apiculate, with lateral acute tubercles and a narrow and smooth median nerve. Conversely, the mericarps of P. dusenii are strongly tuberculate and the median nerve is little prominent. Concerning the indumentum of the leaf blades, the stellate trichomes of P. salmonea are larger and denser than those of P. guerkeana. On the other hand, in P. dusenii the trichomes of the leaf blades are shorter than those of P. salmonea and P. guerkeana, and the indumentum is tomentose. The color of the corolla also differs, all three species having petals with wine-colored veins and claw, but in P. salmonea the ground-color of the petals is salmon-pink, in P. guerkeana white to pale-pink, and in P. dusenii rose-pink.Published as part of Grings, Martin & Boldrini, Ilsi Iob, 2012, Two new species of Pavonia section Lebretonia subsection Hastifoliae (Malvaceae: Malvoideae) from southern Brazil, pp. 38-46 in Phytotaxa 39 on pages 39-41, DOI: 10.11646/phytotaxa.39.1.3, http://zenodo.org/record/489472
