Lin leg.; sweep net ; SHOU ; BOLD specimen code: NAM 65 ; BOLD sequence ID: NAMCH 055-20 ; BOLD BIN: BOLD: ACK 4896 . Distribution. This is the first record of the species from Namibia , but numerous representatives of the same BIN were previously recorded from South Africa ( BOLD: ACK 4896 , Freeman 1956 ; Freeman and Cranston 1980 ; Curtis 1991 ; Harrison 2004 ; Ashe and O’Connor 2012 ). It is worth noting that this species is otherwise distributed in the Palaearctic ( Austria , Denmark , Finland , Germany , United Kingdom , Italy , Moldova , Mongolia , Netherlands , Norway , Portugal , Slovakia , Spain , Sweden , Switzerland ) ( Ashe and O’Connor 2012 ). It is, therefore, worth considering that the specimen that we have found belongs to a yet undescribed species of Psectrocladius related to P. schlienzi . More material is needed before we can test this hypothesis.
