Abstract
Suckermouth catfishes of the genus Chiloglanis are found throughout tropical Africa. Recent studies highlighted the diversity within this genus remains incompletely documented and nearly 20 new species have been described in the past ten years. Here we describe two new species of Chiloglanis from streams in the Upper Guinean Forest. , new species, is only known from one specimen collected in the St. John River drainage in Liberia and is readily distinguished from other species of Chiloglanis by the number of mandibular teeth and the length of the barbels associated with the oral disc. , new species, from the upper Niger River was previously considered to be a disjunct population of C. micropogon. A combination of several characters diagnoses C. frodobagginsi, new species, from topotypic C. micropogon in the Lualaba River (Congo River basin) and from Central African populations of Chiloglanis cf. micropogon in the Benue, Ndian, and Cross River drainages. The biogeographical implications of the recognition of C. frodobagginsi, new species, the likelihood of finding additional diversity in the streams of the Upper Guinean Forests, and the taxonomy of C. micropogon and C. batesii are also discussed.
