Summary: | Stromboceros koebelei Rohwer, 1910 (Tenthredinidae, Selandriinae) Fig. 39 Notes. Finland: Regio kuusamoensis, Kuusamo Uopajanpuro, YKJ grid coordinates: 7363:3613 [66.342°N, 29.534°E]: 1♂, 2♀, 13.06.2018, leg. Marko Mutanen. 4♂, 17.06.2019, leg. Iina Eskelinen and Riikka Jarkko. 15♂ [approximately], 1♀, 20.06.2020, leg. Marko Mutanen. All specimens in ZMUO. The only previous records in the West Palaearctic were from Russia: Zhelochovtsev (1951) mentioned Archangelsk oblast, “Molotowsk” [since 1956 Severodvinsk], and Ermolenko (1975) wrote [translated] "distributed from Perm and the Urals to Sakhalin and Japan". Zhelochovtsev and Zinovjev (1996) mentioned only “Ural” as the area of occurrence within European Russia. Without locating voucher specimens, it is therefore impossible to decide whether the published distributional information for European Russia is accurate. Stromboceros koebelei occurs in the Russian Far East and Amur Region, but records are lacking from more western parts of the Russian East Palaearctic territories (Zhelochovtsev and Zinovjev 1996). It is also widespread in Japan, and occurs on the Korean Peninsula (Yoshida 2017). In Japan, species of Athyrium (Isaka et al. 2015), Dryopteris, and Polystichum (Naito 1979) have been recorded as host plants. The only known Finnish site for the species is a shady creek valley with mixed trees and rich vegetation. All specimens were swept from Dryopteris expansa (C. Presl) Fraser-Jenk. and Jermy, which is almost certainly the food plant at this site. Other fern species present on the site, including Matteucia struthiopteris, did not yield any adults. It is noticeable that all specimens from several other localities in the same region have turned out to represent the common S. delicatulus, suggesting that S. koebelei is very local and possibly has a narrow host range.
