RESUMEN

ABSTRACT Despite the growing number of studies on mayflies (Ephemeroptera), especially in terms of description of new species and distributional records, the knowledge generated remains scattered across specialized literature. This dispersion poses a challenge for non-specialists, such as ecologists, hindering their ability to promote studies and conservation actions. In order to fill this gap, we are launching EphemBrazil: an online database focusing on the distribution of mayflies in Brazil. The main objectives of this platform are to compile a dataset of distributional information for the valid species of Ephemeroptera in Brazil, provide open access to this dataset through an interactive and easily updated website, and offer dynamic distributional maps for species, genera, and families of Brazilian mayflies. EphemBrazil aims to facilitate the retrieval and access of distributional and basic taxonomic information for the order.

RESUMEN

ABSTRACT The male and female imago stage and a new species of the Hermanella complex are described based on material from Pará State, Northern Brazil: Hydromastodon cf. mikei (Thomas & Boutonnet, 2004) and Paramaka froehlichi sp. nov. The male imago of Hydromastodon cf. mikei can be distinguished from Hydromastodon sallesi by the following combination of characters: (1) body color pattern, especially abdominal terga translucent white with terga I to IV washed with black on posterior margin; (2) compound eyes anteriorly rounded; (3) medial projection of the styliger plate short; and (4) penis lobes close to each other and with posterolateral projection as long as ½ of its length. The male imago of Paramaka froehlichi sp.nov. can be distinguished the from the other species of the genus by the following combination of characters: (1) fore and hind wings with membrane brown; (2) legs uniformly yellowish-white, without distal band; (3) abdominal terga II to VI with marks more expanded laterally, median line absent; (4) medial projection of the styliger plate broad; (5) base of telopenis arising at distal ⅔ of penis lobe; and (6): body size of 6.1 to 7.6 mm.
