Pantanodon Status Raised
Pantandon has recently been raised to family status by Hober and Meinema. Included in the paper on Huber’s Killi-Data, was the creation of 2 new genera and 3 new species.

Pantanodontinae described by Myers (1955) with monotypic genus (Pantanodon) and species (podoxys) have recently been elevated to family level in Cyprinodontiformes following molecular evidence, and parallelly fossil European cyprinodonts, previously placed in †Paralebias Gaudant 2013, were recently reassigned to the extant East African genus Pantanodon Myers 1955, as the only genus in Pantanodontidae, with all extant and fossil species sharing the laterally placed pelvic girdle and the adaptation of the pelvic fins in males. In this study the status and biogeographical distribution of all species (and all known institutional records) within Pantanodontidae is reviewed. Pantanodon is shown to be a diversified group of related species, recent, extant or fossil. Based on new data, on reassessments of old data and on new diagnoses, a division of Pantanodontidae into four genera is proposed: Pantanodon (nominotypical Tanzanian genus), Malagodon nov.gen. (Malagasy genus), Aliteranodon nov.gen. (Kenyan genus), three genera including (recent) East African species, and †Paralebias which includes all fossil Pantanodontidae European species. Pantanodon podoxys Myers, 1955 is revalidated as a distinct species and a closely related species from Tanga (Tanzania) is described as P. propinquus n.sp. Within Aliteranodon nov.gen., a recently collected species from Koreni (Kenya) is herein described as A. ndoano n.sp. and designated as its type species. Several more species are assigned to this new genus: Haplochilichthys stuhlmanni Ahl, 1924 with which Pantanodon podoxys was previously synonymized is revalidated with a new combination and its type locality is proposed as Pangani, in north-eastern Tanzania, after a detailed review of Stuhlmann’s collecting trips between 1894 and 1901; a misidentified species from Ngomeni (Kenya) is formally described as A. rostratus n.sp. and two misidentified miniature species from Tanzania are formally described as A. bucinus n.sp., from Zanzibar Island, and A. filimbi n.sp., from Bagamoyo mainland. Oryzias madagascariensis Arnoult, 1963 is designated as type species of Malagodon nov.gen.; Haplochilichthys jeanneli Pellegrin, 1935 is reviewed and a lectotype is designated following suspicions it may be placed in Pantanodontidae. Based on five significant osteological differences between recent and fossil species reestablishment of the fossil genus †Paralebias is proposed with a subdivision into three species-groups. For the first time the unique larval stage of A. stuhlmanni and A. ndoano n.sp. is disclosed.
