DISTRIBUTION. Known from the Russian Far East (Amur, Khabarovsk, Primorsky and Sakhalin regions), Japan (type locality) and East China. This Eastern Palaearctic species 25 years ago was unexpectedly found in Europe in Czechia ( Gregor et al. 2002). Our series of M. angustifrons from Mordovian Nature Reserve is the second European record. The record from Altai is based on a single female but it is the first Siberian finding of this species. So, the distribution of M. angustifrons needs further study and clarification.

REMARKS. Specimens M. angustifrons collected in Khabarovsk region in 2022 showed interesting seasonal variability. Females collected from 5th to 19th of June have entirely yellow palpi and partly yellow antenna (apex of pedicel and basal third of postpedicel) ( Fig. 10 View Figs ). Males and a single female collected from 22 nd to 30th of June have palpi entirely or mostly black, antenna almost indistinctly yellow at border between pedicel and postpedicel) ( Fig. 11 View Figs ).

Examination of other material confirmed that freshly emerged specimens of M. angustifrons have dark palpi and antenna, while in aged specimens palpi and antenna become entirely or partly yellow, respectively.
