Diagnosis.
Trissolcus edessae
may be distinguished from the native species of Nearctic
Trissolcus
in the
Trissolcus flavipes
group (
T. brochymenae
,
T. euschisti
, and
T. strabus
) by the abruptly bicolored female antennae. It may be separated from
T. japonicus
by the presence of 2 clypeal setae and the episternal foveae that do not form a continuous line from the postacetabular sulcus to the mesopleural pit. It may be separated from
T. cultratus
by the absence of parallel arched rugae on the frons. In
T. edessae
a median mesoscutal carina is often present, and this is absent in
T. cultratus
and
T. japonicus
.
Johnson (1984)
used the absence of a mesopleural carina in
T. edessae
as a diagnostic character. Our examination included a specimen in which the mesopleural carina is present (Fig.
58
) and thus we prefer not to use this character for identification. A result of this is that unambiguous identification of male specimens may require movement or removal of the wings to properly evaluate the surface sculpture within the axillar crescent.
