Other characters, however, suggest that it is more closely allied to geographically close species of the subgenus  Sipalotricha, suggesting that the presence of a tubercle on the male tergite VII is an autapomorphy rather than a synapomorphy shared with  Geostibaleonhardi(BERNHAUER, 1908) from Italy, the typespecies of Chondridiosipalia. This conclusion is also supported by the observation that there is no other species of Chondridiosipaliain the West Palaearctic east of Italy. 2609440635 2018-05-28 R, V Brachat & Meybohm Georgia 1720 42.683334 Shovi 1148 43.7 19 1052 5 4 1 2609440616 2018-05-28 V Brachat & Meybohm Georgia 1570 42.7 Shovi 1148 43.683334 19 1052 1 1 2609440609 2018-05-28 V Brachat & Meybohm Georgia 1170 42.7 Glola 1148 43.6 19 1052 2 2 2609440617 2018-05-29 V Brachat & Meybohm Georgia 1310 42.75 Ghebi 1147 43.533333 19 1052 1 1
