We consider a sequence of independent and identicaly distributed (iid) random variables with absolutely continuous distribution function F(x) and probability density function (pdf) f(x). Let Rnl be the largest observation after observing nth record and R(ns) be the smallest observation after observing the nth record. Then we say Wnr = Rnl− R(ns), n > 1, as the nth record range. We will c...

In the Japanese typhlocybine fauna, three already known and three newly recorded species of the genera Anufrievia, Empoascanara, and Anzygina are redescribed and reported with brief notes on their taxonomy and biology: A. akazu (Matsumura), A. ciconia Dworakowska, E. bisignatella (Matsumura) comb. nov., new record, E. kotoshonis (Matsumura) new record, E. sonani (Matsumura) and A. honiloa (Kirk...
