FIGURE 2 in African weakly electric fishes of the genus Petrocephalus (Osteoglossomorpha: Mormyridae) of Odzala National Park, Republic of the Congo (Lékoli River, Congo River basin) with description of five new species

FIGURE 2. Knollenorgan rosettes depicted on a schematic drawing of the head of a specimen of Petrocephalus pulsivertens n. sp. Dense clusters of Knollenorgan electroreceptors on the heads of this and several other Petrocephalus species were described by Harder (1968) as the "Augenrosette," "Nackenrosette" and "Kehlrosette," depending on their position on the head. Each black point represents a single Knollenorgan electroreceptor. Several isolated Knollenorgans occur outside these three rosettes (in this individual of P. pulsivertens), but they are not indicated in the drawing for clarity.
