Family CICHLIDAE Cichlids (part 5 of 7)

Subfamily PSEUDOCRENILABRINAE African Cichlids (Palaeoplex through Yssichromis)

Palaeoplex Schedel, Kupriyanov, Katongo & Schliewen 2020    palaeoplex, a key concept in geoecodynamics representing the total genomic variation of a given species in a given landscape, the analysis of which theoretically allows for the reconstruction of that species’ history; since the distribution of P. palimpsest is tied to an ancient landscape (upper Congo River drainage, Zambia), the name refers to its potential to elucidate the complex landscape evolution of that region via its palaeoplex

Palaeoplex palimpsest Schedel, Kupriyanov, Katongo & Schliewen 2020    named for how its palaeoplex (see genus) is like a palimpsest (a parchment manuscript page, common in medieval times that has been overwritten after layers of old handwritten letters had been scraped off, in which the old letters are often still visible), revealing how changes in its landscape and/or ecological conditions affected gene flow and left genetic signatures by overwriting the genome several times, whereas remnants of more ancient genomic signatures still persist in the background; this has led to contrasting hypotheses regarding this cichlid’s phylogenetic position

Pallidochromis Turner 1994    pallidus, pale, referring to pale coloration of all specimens observed at the time; chromis, a name dating to Aristotle, possibly derived from chroemo (to neigh), referring to a drum (Sciaenidae) and its ability to make noise, later expanded to embrace cichlids, damselfishes, dottybacks and wrasses (all perch-like fishes once thought to be related), often used in the names of African cichlid genera following Chromis (now Oreochromis) mossambicus Peters 1852

So they woke the little serving maid who was from the next village and had a perfectly symmetrical mouth, and she put out the candle – with her little slipper”; allusion not explained, perhaps referring to its symmetrical or nearly symmetrical jaws and/or distinctive dentition of the genus (very broad bands of minute, bristle-like, movable teeth with recurved tricuspid crowns) compared to other cichlids with much narrower tooth bands and fewer tooth rows, thereby making Petrochromis among other cichlids like the serving maid among the crooked-mouthed villagers (Max E.
