Copidognathus magnipalpus ( Police, 1909)

Material examined

One male (FDHAL-21/6), one female and one deutonymph, El Pris (sand, 8 m); one male, La Barranquera (sand, mediolittoral zone).

Diagnosis

Lengths of males were 325 and 365 µm, of a female 297 µm and 325 µm in a deutonymph ( Fig. 3F ). Porose areolae of all dorsal plates with canaliculi arranged within polygons. Setae ds-1 on AD, ds-2 within striated integument between AD and OC, ds-3 to ds-5 on PD. Copidognathus magnipalpus is close to C. loricifer . Both species have “Y” shaped areolae on AD. They can be easily distinguished by the type of areolae on AD (ovate porose polygonal areolae in C. magnipalpus , in C. loricifer with rosetta pores) ( Bartsch 1979; 2001).

Remarks

Copidognathus magnipalpus was described from the Mediterranean Sea (Tyrrhenian Sea, Italy) by Police (1909). Afterwards the species was reported several times from the Black Sea ( Viets 1928; Konnerth-Ionescu 1971; Bartsch 2001, 2004) and Mediterranean Sea ( Bartsch 1975; Mari and Morselli 1990; Morselli and Mari 1993; Durucan 2019b). The morphological characteristics and habitat preferences of the specimens from Tenerife are in accordance with previous reports of the species from Türkiye ( Bartsch 2001; Durucan 2019b). The female specimen with ciliated by “ Praethecacineta halacari (Schulz, 1933) ” ( Figs. 4H, I ), which has been recorded from various halacarid mite species and different areas worldwide ( Bartsch 2001; Chatterjee et al. 2018; Durucan and Boyaci 2019; Durucan and Dovgal 2022). The record of ciliate species “ P. halacari ” is also the first one from the Canaries.
