Tetartopeus lentus RYVKIN, 1989

( Figs 7 , 9-10 )

Material examined: Russia: 1, 1, N-Mongolia , " Shangai ", leg. Leder ( NHMW, cAss).

Comment: Tetartopeus lentus was originally described from the Transbaikal region; the aedeagus is illustrated by RYVKIN (1989). The previously unknown female secondary sexual characters are as follows:

: tergite VIII ( Fig. 9 ) transverse, with almost truncate and in the middle weakly pointed posterior margin; sternite VIII ( Fig. 7 ) much longer than tergite VIII, posteriorly produced and broadly truncate; tergite IX ( Fig. 10 ) deeply and narrow incised posteriorly.

The above specimens represent the first record from Mongolia.
