Glp lateral to costae of PD at the level of insertion of leg IV. Ds-4 and ds-5 on PD. Ds-6 on anal cone ( Fig. 12G ). AE with three long (33) setae and pair of epimeral pore (5). GP large, almost quadrangular, a pair of genital acetabula. No setae on genital plate ( Fig. 12H ). Gnathosoma longer than wide. Tectum triangular ( Fig. 12I ). Leg I short. Telofemura I, genua I and tibia I with lamellae ( Fig. 12J ).Leg chaetotaxy from trochanter to tarsus (bipectinated setae between parentheses, parambulacral setae and solenidia excluded): leg I: 1, 2, 3, 4, 5(1), 6; leg II: 1, 2, 3, 4, 4(1), 3; leg III: 1, 1, 2, 3, 5(1), 4; leg IV: 0, 1+2 (basifemur + telofemur), 3, 5(1), 3.

Remarks

Copidognathus remipes is another species belonging to the C. gibbus species group. It was previously reported from Antalya (Yakamoz Beach) in fine sand sediment habitats at a depth of 6 m, based on adult specimens ( Durucan 2019). In this study, the protonymph stage of the species is reported and illustrated for the first time from Antalya, Türkiye .
