DNA Barcode : The DNA barcode sequences of two specimens of Ophion fossulatus are available at the BOLD systems database: sample id. NJP742/744, sequence id. LNU2578-21/2580-21. Remarks : Previously synonymized with Ophion mocsaryi Brauns, 1889 . Study of the type shows that this species belongs to the Ophion parvulus aggregate, which is characterized by the evenly curved radius and the weakly defined pleurosternal angles. Very similar to the Northern and Central European species Ophion parvulus Kriechbaumer , but with the carination of propodeum more strongly raised, usually both anterior and posterior transverse carinae and central and lateral longitudinal carinae complete, and the pleurosternal angles more prominent. The two barcoding sequences that were extracted, cluster in BOLD with O. parvulus and obviously the two species are very closely related. The minor differences in morphology motivates the treatment of O. fossulatus as a separate species, but undoubtedly the taxonomy of the aggregate would benefit from a more thorough study using integrative methods.
