SPECIMENS EXAMINED. Russia: Far East: Primorsky Terr., Anisimovka,

17.VII 1974, 1 ♀ ( AL); same locality , 7.VII 1975, 1 ♀ (Sysoeva); 50 km N Ol’ga ,

30.VII 1979, 1 ♀ (SB) [IBSS].

DISTRIBUTION. * Russia (Primorsky Territory); India (Assam).

REMARKS. This is one of the most noticeable and unexpected new records for

Russia. Elampus assamensis (Mocsáry, 1911) was previously known only from

India (Assam). The Russian specimens were collected in the broad-leaved forest on the south of Primorsky Territory, where recently another Hymenoptera from the family Mymaridae ( Camptoptera matcheta Subba Rao, 1989 ) was discovered with a similar distribution (Triapitsyn, 2017). Both cases support the hypothesis about the conservation of the relict (Tertiary) fauna in the south of the Russian Far East and its connection with the Oriental region.

Elampus assamensis is one of the most noticeable Elampus because of several primitive features, unusual for the genus Elampus and more similar to some Philoctetes species, namely metascutellum with short, stout lamella; T3 apical margin not produced in a horseshoe-shaped or falcate rim or any other typical shaped truncation of the genus Elampus , but simply with a small apical notch; moreover, the female is without row of setae beneath genae (genal fringe), as females in the genus Philoctetes .
