“…Recently, Correia et al (2018) also presented evidence that Microcaecilia is paraphyletic with respect to Brasilotyphlus . The placement of Luetkenotyphlus brasiliensis within Siphonops contrasts with results of Pyron and Wiens’ (2011) and Maciel et al's (2019) analyses that found Luetkenotyphlus and Siphonops to be sister taxa. Although analyses by San Mauro et al (2006), San Mauro et al (2014) and Correia et al (2018) also recovered Luetkenotyphlus and Siphonops as sister groups, these studies only included one species of Siphonops ( S. annulatus ).…”

A new species of the genus Caecilia (Caeciliidae) from the western foothills of the Serranía de los Yariguíes in Colombia is described. Caecilia pulchraserranasp. nov. is similar to C. degenerata and C. corpulenta but differs from these species in having fewer primary annular grooves and a shorter body length. With this new species, the currently recognized species in the genus are increased to 35. Mitochondrial DNA sequences, including newly sequenced terminals representing two additional, previously unanalyzed species, corroborate the phylogenetic position of the new species within Caecilia and the monophyly of the genus. This analysis also included newly sequenced terminals of Epicrionops aff. parkeri (Rhinatrematidae) and trans-Andean Microcaecilia nicefori (Siphonopidae). Evidence was found for the non-monophyly of the family Siphonopidae and the siphonopid genera Microcaecilia and Siphonops. The implications of these results for caecilian systematics are discussed and the status of the trans-Andean populations of Caecilia degenerata is commented upon.

“…The region currently remains in constant degradation, mostly fragmented into isolated archipelagos of small forest fragments surrounded by open-habitat www.nature.com/scientificreports www.nature.com/scientificreports/ matrices, with only less than 10% of its original coverage 25,41,42 and only about a third of its total extent preserved by conservation units 24 . Nevertheless, even those remaining forest fragments still harbor a multitude of newly discovered animal taxa including both vertebrates [43][44][45] and invertebrates [46][47][48][49][50][51] . Currently, the largest and best preserved portions of the Brazilian Atlantic rainforest are situated near the southern mountain ranges including Serras do Mar and da Mantiqueira 42 , where all Jurasaidae known thus far were collected.…”

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...

“…The Brazilian Atlantic Forest biome is one of the world's biodiversity hotspots (Myers et al 2000), although it has now been reduced to only around 12% of its original cover as a result of centuries of intense deforestation (Ribeiro et al 2011, SOS Mata Atlântica, INPE 2018. Approximately 625 amphibian species (Haddad et al 2013) and 300 reptiles (Tozetti et al 2017) are known to occur in this biome, and new species are still being steadily described (e.g., Cruz et al 2019, Maciel et al 2019, Prates et al 2019). In the state of Rio de Janeiro, 201 species of amphibian have been recorded, including 197 anurans and four caecilians (Dorigo et al 2018), together with 149 reptiles (Oliveira et al 2020).…”

Amphibians and reptiles from the Parque Nacional da Tijuca, Brazil, one of the world’s largest urban forests

The Parque Nacional da Tijuca in Rio de Janeiro, Brazil, is considered to be one of the world’s largest urban forests, however no systematic inventory of its herpetofauna is available. In the present study, we surveyed the amphibians and reptiles of this park to assess its species composition (including secondary data) and obtain estimates of species richness and abundance. We conducted active searches (460 hours) between January 2013 and December 2015. We identified the taxa endemic to either the Atlantic Forest or Rio de Janeiro state, and verified the conservation status of each species in the international, Brazilian, and state red lists. We also estimated the species richness and sampling sufficiency by rarefaction curves and Bootstrap richness estimator, and analyzed the distribution of the species abundance in Whittaker plots. We recorded 3,288 individuals over 36 months, representing 24 species of amphibians and 25 reptiles. The cumulative species curves, rarefaction, and the richness estimated indicated that sampling effort was adequate. Species abundance adjusted to the log-series model in both amphibians and reptiles. The four most abundant amphibians represented 70% of the individuals recorded in this group, while the two most abundant reptiles represented 60% of the total individuals. The inclusion of the secondary data raised the number of amphibian species to 38, and the number of reptiles to 36. Approximately 80% of the amphibian species and 28% of the reptile species recorded are endemic to the Atlantic Forest, and six of the amphibian species are endemic to Rio de Janeiro state. Six amphibian species and one reptile species are classified under some threat of extinction, and two reptile species were exotic. The considerable diversity of the herpetofauna of the Parque Nacional da Tijuca, which includes endemic and threatened species, reflects the effectiveness of the reforestation of this protected area and emphasizes the importance of its conservation.
