From latin cultella , knife, referring to the shape of the ventral phallomere. DNA barcode. Two Norwegian Psychoda cultella sp. n. specimens (GenBank accession numbers JQ 349633 and JQ 349634), have been sequenced for their COI – 5 P barcoding region (658 bp). Kimura parameter 2 (K 2 P) distance between these specimens was small, only 0.46 %, i.e. three nucleotides between the sequences were different in the following sites: 118 (C/T), 256 (A/C), 616 (C/T). These differences have no effect in the coding of amino acids. Compared to some Fennoscandian Psychoda species, P. cultella sp. n. seems to have rather isolated position: its pair-wise K 2 P distances between P. s a tc h el li Quate, P. grisescens Tonnoir, P. phalaenoides Linnaeus and P. lobata Tonnoir are each about 10 % (G.M.
