Scott,

Good for you, a true observer! Yes, A. Papagei, along with A. sp. Pebas, and a
couple of other unnamed forms from Peru, all show a "caudal patch" made out of
the caudal spot and a dark part of Bar 7. It is similar to that seen in the
commbrae-complex species (A. commbrae, A. inconspicua, A. linkei, & some
intermediates) from the Rio Guaporé/Paraguay systems. The former group, called
the Pebas-complex (in the regani-group) can be separated from the
commbrae-complex (also in the regani-group) by certain dark markings most easily
seen in brooding females. The females of the Pebas-complex show very few spots
(only 2 - 4) along the lateral band while in brood dress. Females of the
commbrae-complex show 6 - 7 lateral spots. Pebas-complex forms all exhibit a
series of dorsal spot similar to eunotus-complex & macmasteri-group species. The
same dorsal spots on commbrae-complex species generally have very indistinct
borders and usually form a poorly formed band of sooty gray along the back. The
Pebas-complex species are (so far) much more colorful and slightly larger forms
than those of the commbrae-complex. The commbrae-complex occurs in the Guaporé &
Paraguay drainages of Bolivia, Brazil, & Paraguay. The Pebas-complex is found in
the Amazonas drainage of northeastern Peru. The commbrae-complex is most closely
related to the resticulosa-complex while the Pebas-complex shows relationships
to the regani- & cruzi-complexes.
