Remarks. Along with Pseudaplatopterus and Kolibaceum, the genus Helcophorus has both fossil and modern representatives. However, unlike in Pseudaplatopterus and Kolibaceum, whose living species are referred to separate subgenera ( Eropterus Green, 1951, a subgenus of Pseudaplatopterus, and Laterialis Kazantsev, 1990 and Tricostaeptera Kazantsev, 1997, subgenera of Kolibaceum), both extinct and extant species have been discovered in both subgenera of Helcophorus (Kazantsev, 2015; 2020).

Distribution. Southeast of Palaearctic and north of Oriental realms. Fossil taxa known from Baltic and Rovno amber (Fig. 5).
