Macrobiotus kazmierskii Kaczmarek & Michalczyk, 2009b [T] Macrobiotus kazmierskii sp. n. ( Kaczmarek & Michalczyk 2009b ) Terra typica : Argentina (South America ) Argentina : • 41°11.551´S , 71°49.908´W / 41°12′N , 71 ° 50′W ; 1,100 m asl [ 1,000 m asl]: Rio Negro Province, Nahul Huapi National Park, Ventisquero Negro, Nothofagus forest, moss on rocks. Kaczmarek & Michalczyk (2009b) Record numbers: Argentina : 1; total: 1. Remarks: Currently endemic to Argentina , this species belongs to the persimilis subgroup (with a smooth egg shell) within the Macrobiotus hufelandi group. The hufelandi group requires careful taxonomic analysis, including egg morphology, to differentiate the individual species (see Bertolani & Rebecchi 1993 ; and e.g. Fontoura et al. 2008 , Kaczmarek & Michalczyk 2004, 2009b, Pilato et al. 2003b , Bartels et al. 2009 , Guidetti et al. 2013 for new species within this group).
