Comments.
The
holotype
of
A. cristiani
came from a series of Berlese samples from the Tatamá elevational transect studied by van der Hammen
et al
. (van der
Hammen & Ward 2005
). I examined three additional workers provided by P. S. Ward. Two were from two additional sites on the Tatamá transect (TATA206 and TATA212, at
1540 m
and
1950 m
elevation, respectively), and one was from a wet forest site in Pichincha Province,
Ecuador
, at
1500 m
(PSW11503.9). The specimens showed discordant character variation. The
Ecuador
and TAT
212 specimens
have similar mandibular dentition: there are three main apical teeth, two or three small denticles, and a broad triangular tooth that is near the basal tooth. Thus, these specimens exhibit the character of the Central American species
A. dentivagans
,
A. mackayi
,
A. nortenyo
, and
A. quetzal
. The mandibles on TAT206 are difficult to observe, but one partially open mandible appears to have a more typical dentition, lacking the large triangular tooth on the basal margin. The
Ecuador
and TAT
206 specimens
have the petiolar node smooth and shiny; the TAT
212 specimen
has the node irregularly rugose.
