“…Despite its harsh living conditions, Movile Cave ecosystem is known to harbor a diverse and unique fauna. The cave hosts 51 invertebrate species, of which 34 species are endemic ( Sarbu et al 2019 ). Among these species, some present a number of unique adaptations to a troglobitic life in caves, such as the troglobiont water scorpion Nepa anophthalma Decu, Gruia, Keffer & Sarbu, 1994 ( Hexapoda , Hemiptera , Nepidae ); the nesticid and liocranid spiders Kryptonesticus georgescuae Nae, Serban & Weiss, 2018 ( Araneae : Nesticidae ) and Agraecina cristiani (Georgescu, 1989) ( Araneae , Liocranidae ); the cave leech Haemopis caeca Manoleli, Klemm & Sarbu, 1998 ( Annelida , Hirudinea , Haemopidae ) and the isopod Armadillidium tabacarui Gruia, Iavorschi & Sarbu, 1994 ( Crustacea , Isopoda , Armadillidiidae ) ( Sarbu et al 2019 ).…”
