Bolivia : Santa Cruz : Amboro National Park , Guarda Parque Mataracu , 21-27.xi.2004 , malaise trap , leg. Robertson , Garcia , & Vidaurre ( 1 female , UMSP) . Peru : Cusco : Quispicanchi Province , streams 1 km N Quince Mil , 13°13.335'S , 70°46.035'W , 730 m , 9.i.2020 , leg. Baca. , Slow rivulets & pools w/ saturated detritus next to stream, PE20-0109-02A ( 1 female , SEMC, DNA voucher SLE2140) . Remarks. We examined two single female specimens from unique localities that we refrain from identifying or describing, due to the lack of male genitalia for comparison. The specimen from Peru likely represents an undescribed species, as suggested by its distant position in our DNA tree (Fig. 1 ). The single female from Bolivia is the first and only known record of the genus from that country.
