Spilogona lapponica

Spilogona lapponica (Ringdahl, 1932) Figs 5 B–G Limnophora (Spilogonoides) lapponica Ringdahl, 1932: 158. Type-locality: “Ich fing die Art in zwei männlichen Stücken am Strande vom Torneträsk (Regio subarkt.) in dem nördlichsten Lappland, Juli” [SWEDEN, Torne Lappmark]. Spilogona compacta Huckett, 1965: 198, 208 (key), and 214. Type locality: “ Indian House Lake, Quebec, 7.30 ... 54 [i.e. 30.vii.1954], W.R. Richards ” [CANADA, Quebec] [seen]. Syn. nov. Spilogona lapponica (Ringdahl, 1932); Tridrikh & Sorokina, 2021: 827, 830 (Magadan region). Notes. The type material of Spilogona compacta (in Canadian National Collection) and European and Asian specimens of Spilogona lapponica were examined. The descriptions of both species and the male terminalia are the same. Males of this species are very distinctive with a very broad frons; a stout thick abdomen with an unusually large sternite 5 (Fig. 5B, F); costa with a strong costal spine in both sexes (Figs 5D, E); mid tibia usually with ad setae and hind femur usually with several short pv setae. I conclude that Spilogona compacta Huckett, 1965 is a new junior synonym of Spilogona lapponica (Ringdahl, 1932). There is no description of the female of Spilogona lapponica in Hennig (1959b), but there is the description of the female of Spilogona compacta in Huckett (1965: 215). Additional material examined.
