According to
Alexander
et al.
(2001)
,
Trichomyia pedicillata
Satchell
, known only from the
type
locality in
Panama
, also has three pairs of long, hooked bristles on tergum 7, although the authors did not provide a formal description of this character nor of the material studied. This character was not included in the original description by
Satchell (1956)
. We did not have access to the
type
material of
T. pedicillata
, and until new observations can be made, this species is not included in
Septemtrichomyia
.
Diagnosis.
Head subcircular. Antenna with 13 pyriform and slightly asymmetrical flagellomeres. Maxillary palpus 3-segmented, first palp segment with inner sensorial pit; medial fork at the approximate center of the wing. Tergum 7 with pair of lateral lobes, each one with 3–5 elongate bristles on tergum 7, sometimes fused (as a single bristle). Hypandrium fused with gonocoxites. Gonocoxite with one posterior arm convergent to the midline, usually with rod-like setae on the inner margin. Gonostylus unsclerotized, ventrally articulated to the gonocoxite near the apex.
Comments.
Bravo (1999)
proposed that the gonostylus of the subgenus
Septemtrichomyia
has two distal arms, one dorsal arm and one ventral. However, based on a reexamination of the
type
specimens of
T. bou
,
T. cauga
and
T. mishi
and studies of new material, it is clear that there is only one arm (
i.e.
the second arm is actually the gonocoxite projected posteriorly).
Bravo (1999)
misinterpreted the gonostylus, which is ventral and articulated near the apex in all of the species of this subgenus.
