Trichonta comica

Material examined. U1
21.XI.05
1 ♂
(det. by O. Kurina).
Chorotype.
Type
1 [1.01 of
Vigna Taglianti
et al.
(1999)
]. Holarctic, in Europe a mainly nordic distribution but has also been recorded from the French mainland,
Switzerland
and
Montenegro
(included under the former
Yugoslavia
by
Chandler (2004a)
based on an unpublished record).
Italian distribution.
Sardinia
only.
Notes.
[O. Kurina pers. comm.] The specimen has both hind legs and one fore and mid legs lost but terminalia have survived. Using the key by
Gagné (1981)
it runs to the couplet including the rare Holarctic species
Trichonta comica
Gagné, 1981
and the Palaearctic
T. concinna
Gagné, 1981
. The lateral part of the gonostylus is identical with Gagné’s fig. 71 but tergites 9–10 are most similar to
T. concinna
(Gagné’s fig 76). Further, the aedeagal projections in this specimen are dorsoventrally hooked (visible in lateral view). Gagné used the term “twisted” (probably equivalent to hooked) for
T. concinna
and straight for
T. comica
but the specimen is more similar to
T. comica
.
