Copidognathus magnipalpus ( Police, 1909) ( Figs. 12A–C , Table 4)

Morphology and notes

Protonymph – Idiosomal length 237–280. Porose areolae of dorsal plates with canaliculi arranged within polygons ( Fig. 12A ). AD with an anterior and two posterior porose areola. OC with two corneae. PD anteriorly ovate. Ds-1 on anterior edge of porose areaolae on AD. Pairs of ds-2 and ds-3 on striated integument. Ds-4 and ds-5 on PD. AE with three setae and pair of epimeral pore. GP small, ovate, a pair of genital acetabula. No setae on genital plate ( Fig. 12B ). Tibia I with one smooth and one dentate seta ( Fig. 12C ). 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. Each of tibiae I to IV with one bipectinate setae. All legs with two lateral claws with accessory process but large pectines (oil immersion) and a small bidentate median claw.

Remarks

Adults of C. magnipalpus were previously reported from several locations in Antalya (Yakamoz Beach, Bilem Beach, and Finike) in macroalgae habitats at various depths (1, 2, and 6 m) ( Durucan 2019), as well as from Sinop in the Black Sea (Bartsch 2001). In this study, the protonymph stage of the species is reported and illustrated for the first time from Antalya, Türkiye . The protonymph stage, as described and illustrated by Bartsch (2001) from the Black Sea, corresponds with the specimen from the Levantine Sea, Türkiye.
