ABSTRACT Here we describe a dataset of freely available, readily processed, whole-body μ CT-scans 56 species (116 specimens) Lake Malawi cichlid fishes that captures considerable majority the morphological variation present in this remarkable adaptive radiation. We contextualise scanned specimens within discussion their respective ecomorphological groupings and suggest possible macroevolutionary studies could be conducted with these data. also methodology to efficiently CT-scan (on average) 23 per hour, limiting scanning time alleviating financial cost whilst maintaining high resolution. demonstrate utility method by reconstructing 3D models multiple bones from dataset. hope will enable further study fascinating system permit wider-scale comparisons other radiations.

A new species of cichlid fish, Lethrinops atrilabris is described from specimens collected by trawling at a depth around 90 m off Monkey Bay, southern Lake Malawi. It assigned to the genus on basis its vertical flank barring, lack enlarged cephalic lateral line canal pores and form lower jaw dental arcade. can be distinguished congeneric male breeding dress contrasting barring dark ventral surface, most strikingly lips, throat chest, relatively small known maximum size [<75 mm standard length (SL)], large eyes (38%-41% head length), laterally compressed body (depth 2.5-2.7 times max width) gill raker count (13-14).

A new species of cichlid fish, Lethrinops chilingali is described from specimens collected Lake Chilingali, near Nkhotakota, Malawi. It assigned to the genus based on form lower jaw dental arcade and by absence traits diagnostic phenotypically similar Ctenopharynx, Taeniolethrinops Tramitichromis. also lacks enlarged cephalic lateral line canal pores found in Alticorpus Aulonocara. The presence a broken horizontal stripe flanks females immature/non-territorial males distinguishes them all congeners, including lethrinus, which typically continuous. has relatively shorter snout, lachrymal bone less ventrally positioned mouth than lethrinus. appears likely that now extinct wild, as this narrow endemic not been positively recorded natural environment since 2009. Breeding populations remain captivity.
