Genomic resources, such as draft genomes, are vital for biodiversity monitoring and conservation. For endangered species, they enable the development of tools like organellar genomes and molecular markers, which are crucial for population genetics. Advances in sequencing technologies now allow high-throughput genotyping with detailed amplicon sequences, enhancing genetic variation studies. The northern muriqui (), a critically endangered primate endemic to Brazil's Atlantic Forest, currently lacks both nuclear and mitochondrial genome data and species-specific microsatellite markers for population genetic studies. We assembled a 2.52 Gb draft genome for with 202,243 contigs (N50 = 29,134 bp), and BUSCO analyses indicated 52% completeness and 15.5% fragmented genes. The complete 16,635 bp mitochondrial genome retains the conserved mammalian structure with 22 tRNAs, 2 rRNAs, 13 CDS, and an origin of replication. Additionally, we designed 31 SSR primer pairs suitable for non-invasive sampling and genotyping, alongside two mtDNA and two sex-determination primers, configured into three multiplex PCR sets. These genomic resources, including the draft genome, complete mitochondrial genome, and microsatellite markers, provide essential tools for evolutionary analyses and the genetic monitoring of populations, supporting its conservation.
