Barbus arcislongae, a Lake Malawi endemic, is perhaps the least known of the lake's small barb species. It was described by Keilhack (1908) from three specimens collected at the north end of the lake, and was originally called Barbus trispilopleura arcislongae but later recognized as a full species by Boulenger. There are at least two additional specimens in Belgium's Musée royal de l'Afrique Centrale from 4 km north of "la baie de Nego, lac Nyassa," Mozambique, collected in 1979 (FishBase). (No such locality as Nego is listed for Mozambique on the GEOnet Names Server; possibly this is the same as Ngôo or Ngoo, a village on a small bay on the central Mozambique coast?)
In the Malawi barb fauna, B. arcislongae is characterized by having all of the following:
No bionomic details or even a maximum size is given in the literature available to me (including the unusually sparse species account at FishBase), and no illustration of the species is at hand.
