860F1679FFF88F1BFD9A55F2FB1CCC1A.taxon	materials_examined	Material examined Two females (FDHAL- 21 / 1), La Barranquera (Corallina ferreyrae, mediolittoral zone). Diagnosis The lengths of females' idiosoma were between 470 and 500 μm. Dorsal and ventral plates large. Dorsal plates and margins of idiosoma with cerotegumental lamellae. Known length range of female idiosoma is 440 – 539 µm long (Bartsch 2016). All dorsal plates bear longitudinal cerotegumental costae. Both margins of AD rounded. Wide cerotegumental lamellae on idiosoma and legs with honey comb-like ornamentation, which is the most distinctive characteristic among other very close Agaue species (A. chevreuxi and A. panopae). OC with two corneae and eye pigment. The ovipositor extends to the anterior margin of GA. Rostrum slender, slightly longer than gnathosomal basis. Both pairs of maxillary setae long. Telofemora with prominent cerotegumental cover. Claws slender, accessory processes minute, 5 – 9 tines can be seen in the basal part of the concave flank (Figs. 3 A, 5 A, B, 7 A – D). Remarks This species was described by Viets (1940) for the first time for the Mediterranean Sea (Adriatic Sea, Croatia) from a variety of habitats and depths. Afterwards the species was recorded in Italy (Mari and Morselli 1990), Cadiz (Spain) and France (Bartsch 2016). The morphological characteristics of the female specimens and idiosoma sizes from Tenerife accord with previous reports of the species from Croatia and Italy (Viets 1940; Mari and Morselli 1990).	en	Durucan, Furkan, Paz, Juan Carlos De La, Hernández-Teixidor, David (2023): Halacaridae (Acari) from Tenerife (Canary Islands).

860F1679FFF98F1BFDFB51A1FC4EC998.taxon	materials_examined	Material examined One female (FDHAL- 21 / 2) and three males, El Pris (Gelidium sp., upper mid-littoral zone); one female and one male, La Barranquera (Gelidium pusillum, upper mid-littoral zone). Diagnosis The length of females was between 400 and 460 µm, and for males, 450 µm. Idiosoma wide and heavily armed. Integument of plates brownish. Raised porose areolae of dorsal plates with canaliculi. Ostia lacking. AD with small frontal process and the plate clearly raised H-like costa. OC with two corneae, porose areola triangular in outline and rounded angles. Eye spots present beneath AD and OC. PD with pair of medial and lateral costae and the plate anteriorly rounded. Ventral plates porose and faintly reticulate. AE wide, posterior margin of AE and anterior margin of GA truncate. Gnathosoma and palps are slender. Rostrum about as long as gnathosomal base (Bartsch 1996) (Fig. 3 B). Remarks This is one of the species most encountered within a genus widely distributed and reported in the Black Sea, Mediterranean Sea and eastern Atlantic (Bartsch 2004; Durucan and Boyaci 2018; Durucan 2020, 2021). In the Atlantic Ocean, A. brevipalpus has been reported from the Azores, Canary Islands, British Isles and continental Spain (Bartsch 2015).	en	Durucan, Furkan, Paz, Juan Carlos De La, Hernández-Teixidor, David (2023): Halacaridae (Acari) from Tenerife (Canary Islands).

860F1679FFF98F1CFE0B557DFBEBCDC5.taxon	materials_examined	Material examined Five males (FDHAL- 21 / 3), one deutonymph, El Pris (Gelidium sp., upper-mid littoral zone); three females, six males, La Barranquera (Corallina ferreyrae, mediolittoral zone). Diagnosis Idiosoma length in females was 420 – 430 µm, in males, 360 – 430 µm and in deutonymph 350 µm. Idiosoma wide, flattened and heavily armed. AD and PD slightly raised longitudinal costae. AD areola M-shaped and the plate slightly longer than wide. OC with two corneae. The species can easily be recognized by having a ventral and two anterior spines on telofemur I, a ventral and three anterior spines on tibia I, two of which are adjacent (Fig. 3 C) (Pepato and Tiago 2003; Mytilineou et. al. 2016; Durucan 2021). Remarks This species is present, at least, in the Mediterranean Sea and eastern Atlantic Ocean (Viets 1940; Bartsch 2009). The morphological characteristics of the specimens reported here accord with records previously given by Mytilineou et al. (2016) and Durucan (2021).	en	Durucan, Furkan, Paz, Juan Carlos De La, Hernández-Teixidor, David (2023): Halacaridae (Acari) from Tenerife (Canary Islands).

860F1679FFFE8F1CFDC25087FCE1CAFC.taxon	materials_examined	Material examined One female and one male (FDHAL- 21 / 4), El Pris (Gelidium pusillum, mediolittoral zone); one male, La Barranquera. Diagnosis Length of the female was 440 µm, and 380 µm for male. Agauopsis tricuspis is characterized by having five spines on telofemur I and being spread along the eastern North Atlantic and Mediterranean Sea (Bartsch 2015) (Figs. 3 D, 5 C, D, 8 A – E). The morphological characteristics of the specimens from Tenerife agree well with the previous reports of the species from France (Roscoff) (Benard 1962) and (Bay of Arcachon) (Bartsch 1976), and Italy (Krantz 1970). Remarks It was originally described by Benard (1962) from France Atlantic (Roscoff, Bloscon) among barnacles (Chthamalus stellatus). Later, the species was reported from the Mediterranean Sea (Adriatic Sea, Venice) amongst mussel beds, by Krantz (1970), and Atlantic France (Bay of Arcachon), again by Bartsch (1976). After that, it was reported from Ireland, United Kingdom, France and Spain, according to Bartsch (1976, 2015).	en	Durucan, Furkan, Paz, Juan Carlos De La, Hernández-Teixidor, David (2023): Halacaridae (Acari) from Tenerife (Canary Islands).

860F1679FFFE8F1DFDFD5470FED9CEA0.taxon	materials_examined	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. 3 E). 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 2019 b).	en	Durucan, Furkan, Paz, Juan Carlos De La, Hernández-Teixidor, David (2023): Halacaridae (Acari) from Tenerife (Canary Islands).

860F1679FFFF8F1DFE0453AAFE54CACE.taxon	materials_examined	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. 3 F). 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).
