Apistogramma inconspicua sp.n. is described from the Rio Candclaria in the Rio Guaporé drainage in Bolivia, and recorded also from Cáceres on the Rio Paraguay in Brazil. The new species is closely related to the Paraguayan species A. commbrae (Regan) and an undescribed species in the Guaporé drainage system. These species share a specialized feature in the colour pattern, viz. an expanded vertical bar on the caudal peduncle which it confluent with the caudal spot. The now presumably complete record of Paraguayan Apistogramma species allows an analytical key to be given. Of the additional species, A. borellii (Regan) and A. trifasciata (Eigenmann & Kennedy) represent two distinct lineages. Apistogramma pleurotaenia (Regan) is probably a La Plata basin species, although no localities are known, and its relationship remain obscure. The assemblage of Paraguayan Apistogramma species reflects the heterogeneity of the Paraguayan cichlid fauna as a whole.
