Notes. The series of Nearctic specimens of Spilogona brevicornis View in CoL and European specimens of Spilogona scutulata View in CoL were examined. The descriptions of both species and the male terminalia are the same. These species are very distinctive in both sexes, with strong presutural acr setae in 2 even rows which are strikingly stronger than the ground hairs ( Figs 5K, L View FIGURE 5 ), and hind femur without pv setae; males with rather broad fronto-orbital plates, which touch and are very silvery, shining; very light grey scutum with a brown spot between post dc; light abdomen with small spots, and a brown dusted scutellum; sternite 5 with with a broad median notch and a pointed caudal margins ( Fig. 5M View FIGURE 5 ).

I therefore conclude that Tetramerinx brevicornis Malloch, 1917 is a new junior synonym of Limnophora (Spilogona) scutulata Schnabl, 1911 .
