Diagnosis.
Amember of the
andinae
species-group and very close to
T. andinae
, but both sexes of
T. elegans
can be distinguished by their smaller dimensions and fewer sternal setae, and by males with a tendency to have fewer tergal setae.

Remarks.
Ranges of male chaetotaxy in specimens examined by us fall within the upper limit or slightly exceed the ranges given by
Hellenthal
et al.
(2002)
, especially for tergites III–VI. A similar pattern applies to tergites III–VIII on females. Body measurements of both sexes are also around the upper limit of the ranges given by
Hellenthal
et al.
(2002)
. However, in the remaining features, our material agrees with those described by
Hellenthal
et al.
(2002)
.
Tinamotaecola elegans
was originally described from Argentinean specimens of three subspecies of
E. elegans
, and also from
Eudromia formosa
from both
Argentina
and
Paraguay
(
Hellenthal
et al.
2002
: 139). Also,
Cicchino & Castro (1998: 121)
had previously noted the presence of this undescribed species from
Argentina
. To date, this
Tinamotaecola
species is confined to the two species of
Eudromia
. All known records of
T. elegans
from
E. elegans
are shown in
Fig. 20
