FIGURE 2. Map of the general area surrounding Lake Tanganyika showing the type localities of three new Chiloglanis species (white square & star) along with those of 16 additional Chiloglanis species previously described from the region (black circles). For those species displaying secondary sexual dimorphism of the caudal fin in adult males, a silhouette of the fin is illustrated.
