Lobellina gladius sp. nov. can be recognized by mandible with six teeth, cephalic chaeta O present and included in tubercle Fr, non-cross type chaetotaxy on cephalic posterior area, cephalic lateral tubercle Dl, L and So independent, Ant. I with 9 chaetae, Th. I with 4+4 tubercles, VT with 6-8 (usually 7) chaetae. New localities of Crossodonthina choui Jiang Zhang, 2012 and Lobellina yinae Jiang, Huang Luan, 2018 are also provided.
