COMMENTS:
Tychus meybohmi
sp. n.
is very similar to
Tychus viti
Besuchet, 2011
from which it can be distinguished by its smaller size (
1.35 mm
T. meybohmi
,
1.60-1.65 mm
T. viti
), by the antennal shape with segments V longer than wide (slightly wider than long in
T. viti
), and by the different shape of the ventral portion and dorsal apophysis of the aedeagal median lobe.
