Comparing Arachnids in Rovno Amber with the Baltic and Bitterfeld Deposits

Аннотация

So far 107 families of chelicerates are known from the Rovno amber, which is comparable with those known from the Baltic amber (144 families) and three times more than in Bitterfeld amber; 19 families of arachnids reported from Rovno amber are not known in Baltic amber deposits. The tropical mite family Eupalopsellidae is excluded from the Rovno amber fauna. The mite family Autognetidae and spider genus Orchestina Simon, 1882 (Oonopidae) are reported from Rovno amber for the first time.
