Abstract Chromosomal inversions contribute to adaptive speciation by linking co-adapted alleles. Querying 1,375 genomes of the species-rich Malawi cichlid fish radiation, we discovered five large segregating in benthic subradiation that each suppress recombination over more than half a chromosome. Two were transferred from deepwater pelagic Diplotaxodon via admixture, while others established early deep clade. Introgression haplotypes lineages inside and outside radiation coincided with bursts species diversification. Inversions show evidence for transient sex linkage striking excess protein changing substitutions points towards selection on neuro-sensory, physiological reproductive genes. We conclude repeated interplay between depth adaptation sex-specific has been central evolution this iconic system.
