“…The Serra dos Toledos reserve is situated in the municipality of Itajubá, Minas Gerais state in the Mantiqueira mountain range. It comprises an area of 10.7 km 2 with altitudes ranging from 1,100 to 1,800 m. The reserve was originally covered by dense ombrophilous and Araucaria forests, but nowadays it includes secondary forests and suffers from the deforestation caused by the surrounding agricultural and livestock activities 52 . The Serra dos Órgãos National Park is situated in the municipality of Teresópolis, Rio de Janeiro state in the Serra do Mar mountain range.…”

Beetles are the most species-rich animal radiation and are among the historically most intensively studied insect groups. consequently, the vast majority of their higher-level taxa had already been described about a century ago. In the 21st century, thus far, only three beetle families have been described de novo based on newly collected material. Here, we report the discovery of a completely new lineage of soft-bodied neotenic beetles from the Brazilian Atlantic rainforest, which is one of the most diverse and also most endangered biomes on the planet. We identified three species in two genera, which differ in morphology of all life stages and exhibit different degrees of neoteny in females. We provide a formal description of this lineage for which we propose the new family Jurasaidae. Molecular phylogeny recovered Jurasaidae within the basal grade in elateroidea, sister to the well-sclerotized rare click beetles, cerophytidae. this placement is supported by several larval characters including the modified mouthparts. The discovery of a new beetle family, which is due to the limited dispersal capability and cryptic lifestyle of its wingless females bound to long-term stable habitats, highlights the importance of the Brazilian Atlantic rainforest as a top priority area for nature conservation.Coleoptera (beetles) is by far the largest insect order by number of described species. Approximately 400,000 species have been described, and many new ones are still frequently being discovered even in regions with historically high collecting activity 1 . Because this group has been intensively studied since the age of early systematists, and most of the major higher-level taxa had already been described by about a century ago, discoveries of new beetle families are nowadays a rare occurrence. The vast majority of recent family descriptions is based on the already known taxa for which a new systematic placement was recovered by the use of phylogenetic analyses 2-5 . Thus, only three beetle families have been erected de novo in the 21st century based on newly collected material. Firstly, Aspidytidae were described based on two species from South Africa and China, which currently represent monotypic genera 6,7 . Secondly, the monotypic family Meruidae was created for a hitherto undescribed lineage from Venezuela 8 . Finally, the new monogeneric family Iberobaeniidae was described based on three species from the southern part of the Iberian Peninsula 9,10 . Whereas both Aspidytidae and Meruidae represent semiaquatic families within the suborder Adephaga, Iberobaeniidae were recovered as a deep branch in the polyphagan superfamily Elateroidea 9 .Elateroidea (the click-beetles, soldier-beetles, fireflies and relatives), the largest superfamily of the series Elateriformia, form one of the major and oldest polyphagan lineages 11,12 . Currently, they contain approximately 25,000 described species classified into 13 families [13][14][15][16] . The elateroid beetles exhibit extraordinary morphological diversity. Some lineages contai...
