Paratype , 1 ♀ : Croatia , Sniježnica Mts., Glogova jama pit, 24.08.2005 , B. Jalžić lgt., ( CDC ). Remarks: Blattochaeta marianii with its subspecies is recorded e.g., Pretner (1977) , Polak & Jalžić (2009) and were collected with additional recent finds in many caves and pits, approximately more than twenty speleological localities in Orjen Mts. and Krivošije Mts. in southwestern Montenegro and several localities in southeastern Bosnia and Herzegovina , except only B. marianii kusijanovici which is currently known only from its type locality in Croatia . Specimens are deposited in different museums and private collections. The type locality of some Blattochaeta marianii ssps., and of Blattochaeta matchai Jeannel, 1924 are not exact, since the collectors, for example Leo Weirather, for unknown personal reasons, in the past often did not provide to the species authors the correct and real names of type localities (caves and pits). This has already been mentioned by Pretner (1977) and Polak & Jalžić (2009) . Based on the above, it would be necessary to collect as much fresh material as possible from most localities from Orjen and Krivošije Mts., for detailed study of all morphological external and internal characters of species to resolve the status and variability of these taxa. Currently, due to the lack of sufficient quantity of material we are not able to resolve here this taxonomic problem.
