Diagnosis
Trichosiopsis subviatica subviatica is characterized by a gonostylus, which is completely rounded dorsally and mesially strictly concave. In contrast to the other subspecies it is smaller and has brighter, nearly yellow legs. The antennal flagellomeres are shorter, particularly the first two. Tr. subviatica subviatica is the only subspecies with a setose posterior pronotum.
DNA Barcoding
The COI sequence is assigned to one part of BIN BOLD:ACK0022 (n=1, K2P: 0.31%).
Discussion
This subspecies is genetically nearly identical to Trichosiopsis subviatica subelongata. However, this result needs to be interpreted with caution, because the only barcoded specimen from Munich is not available and possibly lost. As reference served another specimen from the same sample, which might be different from the original voucher. Contrary to the apparent close genetic similarity with Tr. subviatica subelongata this subspecies is morphologically the most distinctive one.
Distribution
Germany, Russia[1][3], Sweden, Switzerland.
