Remarks.
Mistshenko (1951b: 739)
included this species within the genus
Saxetania
Mistshenko
because of its frontal ridge, the vertex not strongly vertical as in
Tropidauchen
and the hind femur. Dirsh (1952) synonymizing the genus
Saxetania
transferred it to
Tropidauchen
, but all subsequent authors followed
Mistshenko (1951b)
up to the present date. I have separated both genera mainly by the male genitalia. The male genitalia of this species undoubtedly agree with that of
Tropidauchen
.
Mistshenko (1951b)
gave
T. escalerai
and
T. marginatum
in different genera, but Dirsh (1952) distinguished them only by the narrow or wide undulation of the ventral margin of hind femur. The coloration of hind legs and the ventral margin of hind femur are variable even in specimens collected from the same place. Both species
T. escalerai
and
T. marginatum
were identified from the same locality, but I cannot see any important difference between those specimens. Therefore I consider that they are synonyms. On the other hand according to
Uvarov (1922: 364)
“This species differs from
T. securicollis
Sauss.
by unimportant characters and is, probably, only a geographical form of the latter species”. As I stated in the Remarks section of
T. securicolle
above, I also think that this species may be a synonym of
T. securicolle
.
In the NMW, specimens were labelled as paratypes, but they cannot possibly be paratypes, and are syntypes.
