Remarks.
The worker of
B. zwaluwenburgi
is easily distinguished from that of
B. cryptica
by: (1) frontal carinae inconspicuous, extending by no more than the length of frontal lobe; (2) antennal segments VIII–X each shorter than long; (3) posterolateral part of propodeum feebly produced posteriad.
Williams (1946)
described and placed this species under the subgenus
Fulakora
of the genus
Stigmatomma
. “
Fulakora
” was established by
Mann
(1919)
for
Stigmatomma celata
Mann
, 1919
(the
type
species),
S. armigerum
(Mayr, 1887)
,
S. saundersi
(Forel, 1892)
and
S. minutum
Forel, 1913
, and later synonymized with
Stigmatomma
by
Brown 1949
and then with
Amblyopone
by
Brown (1960)
. According to the original description of
S. celata
, and
type
images of
S. armigerum
(CASENT0915647 at AntWeb),
S. minutum
(CASENT0102516 and CASENT0104570 at AntWeb) and
S. saundersi
(CASENT0102518 at AntWeb), the inner margin of mandible has triangular teeth arranged in two rows, or at least a part of the inner margin of mandible has more or less bifid teeth in the worker of these species. Thus, these species do not belong to
Bannapone
.
An examination of the
holotype
and nontype images of
B. zwaluwenburgi
(CASENT0249113, CASENT0173925 and CASENT0187702 at AntWeb) has revealed that the mesosoma of CASENT0173925 in dorsal view is distinctly wider and shorter than that of the other specimens. To determine whether CASENT0173925 is an independent species or an ergatoid of
B. zwaluwenburgi
, colony series are needed.
