Crossodonthina acuminata sp. nov. can be recognized by 3 black eyes per side on head; mandible with 3 basal teeth and 8 rami; all cephalic tubercles independent, chaeta O on tubercle Fr present; cephalic tubercle Di, De on posterior area of head with 2 chaetae each, intermediate between cross and non-cross type chaetotaxy; tubercle De of Th.
