Whole-Genome Sequencing of two <i>Listrura</i> and five <i>Microcambeva</i> Species (Trichomycteridae, Siluriformes), Rare and Threatened catfishes from the Atlantic Forest
<i>Listrura</i> and <i>Microcambeva</i> are two genera of small, rare and elusive catfishes of the Trichomycteridae family, endemic to the Atlantic Forest coastal drainages in Brazil. <i>Listrura</i> comprises 13 species with slender bodies, absent pelvic fins, and a distinct caudal-fin and caudal-peduncle morphology, while <i>Microcambeva</i> includes eight species with translucent bodies, typically buried in sandy substrates with exposed nasal barbels. The two genera inhabit fragile environments that are undergoing accelerated degradation, with <i>Listrura camposae</i> and <i>L. nematopteryx</i> classified as "Critically Endangered" (CR), and <i>L. picinguabae</i> as "Near Threatened" (NT). <i>Microcambeva</i> species face similar threats, with <i>M. bendego</i> proposed as CR and <i>M. draco</i> as "Endangered" (EN). Over the past two decades, collection efforts and taxonomic descriptions have expanded the diversity of these two genera, with descriptions of 11 species of <i>Listrura</i> and seven of <i>Microcambeva</i> species in that period. To address gaps in genetic data for those taxa, we herein present draft version of whole-genome sequences for two <i>Listrura</i> species - <i>L. nematopteryx</i> and <i>L. boticario</i> - and five <i>Microcambeva</i> species - <i>M. barbata</i>, <i>M. watu</i>, <i>M. jucuensis</i>, <i>M. bendego</i>, and <i>M. ribeirae</i>. These genomic data are critical for future studies on the evolutionary history and systematics of these unique catfishes, contributing to foundational knowledge of their biodiversity.
