Gary & Kathy,

A. nijsseni and A. hippolytae are about as distantly related as any two apisto
species can get.
A. nijsseni is an advanced species with reduced cephalic pores. It appears to be
part of the pertensis lineage (pertensis/iniridae-, gibbiceps/brevis-,
agassizii/candidi-, trifasciata-, and cacatuoides/nijsseni-groups). A. hippolytae
is from the most primitive lineage, the steindachneri-lineage (steindachneri/Rio
Preto do Candeias-group). These species have more in common with the closely
related genus Gymnogeophagus than do other apistos. They have a full set of
cephalic pores, narrow lateral band, humeral (flank) patch, and scales with light
central areas. We are just looking at "evolutionary convergence" like dolphins,
sharks, and ichthyosaurs.
