Copidognathus lamelloides Bartsch, 2000

Material examined One male (FDHAL-21/5), El Pris ( Corallina ferreyrae , 1–2 m).

Diagnosis

Idiosoma of only one male was 262 µm long and 187 µm wide. AD with 3 round raised areolae with rosette pores. OC almost as long as AD. Glp-1 is in margins of porose areolae. Telofemora I and II with small ventral lamellae. Tibia IV has bipectinate setae ( Fig. 3E ). According to Bartsch (2001), C. lamelloides resembles to C. brevipes . Distinguishing characters are: position of glp-1 (in margins of porose areolae vs near lateral margin of AD), ds-2 (within striated integument vs on OC), length:height ratio of telofemur I (1.7–2.1 vs 1.5–1.6) and shape of ventromedial seta on tibia IV (bipectinate vs smooth).

Remarks

This species was originally described by Bartsch (2000) from Atlantic France (Baie de Morlaix). It is present in the north eastern Atlantic, Mediterranean Sea and Black Sea ( Bartsch 2009). The morphological characteristics of the specimen from Tenerife agree with the previous reports of the species from Crimea (Black Sea) ( Bartsch 2001) and Türkiye (Levantine Sea) ( Durucan 2019b).
