Trichacis tatika Szabó, 1977: 145

Type material examined. Holotype ♀, Tatika, 12 September 1952, Kaszab ( HNHM).

Molecular analysis. The ASAP analysis revealed that all 170 records from Europe were conspecific and formed a clade with high support (Supplemental File 2). These records came from Belarus, Bulgaria, England, Germany, Finland, and Norway. Worldwide DNA barcode data from BOLD and GBOL indicated the existence of 11 to 13 species of Trichacis based on partitioning. The best ASAP score indicated the presence of 11 species, while the maximum likelihood tree recovered 13 distinct clades that could be considered putative species.

Of the 13 putative species on the tree, seven species were recorded only from Canada, two species from Canada and the USA, one from Tennessee, one from Florida, and one from Honduras. Backbone support was low, although the resulting tree places Isocybus as sister to Trichacis ( Fig. 6 ).
