New records of Sciarosoma nigriclava (Strobl, 1898) are presented from Engerdal in Hedmark and Gargialia outside Alta in Finnmark. This unique species, belonging to the enigmatic Heterotricha-group still unplaced in family, has not been recorded in Norway since the genus and species was described under the name Sciarosoma borealis Chandler, 2002; at the time only a single male from Østmarka Nature Reserve in Akershus was reported. All four specimens of our new material were successfully DNA barcoded and aligned with a single additional sequence of the species available on The Barcode of Life Data System (BOLD), mined from GenBank. The assigned Barcode Index Number (BIN) for the species displays a considerable distance of some 15% to any other Diptera on BOLD, underscoring the isolated phylogenetic position of the species among the Sciaroidea. Both the new collecting sites are situated within or nearby old-growth pine and spruce forests, supporting the view that the species may serve as an indicator of pristine coniferous forest in the boreal Taiga.
