Redescription – Measurements presented in Table 2.
Morphology and notes
Female – All dorsal and ventral plates divided by narrow bands of striated cuticle and the plates with typical rosette pores which have central ostium surrounded by canaliculi ( Figs. 3A, B View Figure 3 ). AD longer than wide (1.15); anterior margin with small frontal lamella ( Fig. 3D View Figure 3 ).
AD with pair of rounded wide areolae; anterior areolae with 15–20 rosette pores, two middle areolae each with about 45–50 rosette pores ( Fig. 3D View Figure 3 ). Dorsal setae small. Pair of ds-1 on AD posterior to pair of glp-1; ds- 2 in anteromedial margin of OC. Posterior end of OC rounded and extending to level of leg III. Raised areolae with 20–25 typical rosette pores. OC with two corneae. Gland pores small. Pore canaliculus slightly posterior to gland pore. ( Fig. 3E View Figure 3 ); ds-3 near anterior margin of PD ( Fig. 3F View Figure 3 ), ds-4 and ds-5 at 0.32 and 0.61 of its total length, respectively. Pair of ds-6 on anal cone. PD have two pair of costae which are prominent, but not join anteriorly. Each medial costae with 5-7 and each lateral costae 3–4 rosette pores wide. Panels between two raised costae are very week, cannot seen clearly. Gland pores inconspicuous.
AE with typical rosette pores ( Fig. 3H View Figure 3 ) but posterior middle part has no porose areas ( Fig. 3B View Figure 3 ). AE with three pairs of ventral setae and a pair of epimeral pores. Epimeral pores 5–7 wide (see Fig. 3B View Figure 3 ). Epimeral processes I and II are large and lamellar ( Fig. 3H View Figure 3 ). Posterior margin of AE and anterior margin of GA truncate. PE anteriad extending to the level of epimeral gland pores, posteriad almost to the level of posterior margin of GO. PE with one dorsolateral and three ventral setae, porose areolae typical rosette pores.
GA mostly with typical rosette pores but some area without pores as shown in Figure 3B View Figure 3 . Distance from anterior pgs to GO equalling 0.72 the GO's length. Ovipositor extending beyond GO but not reaching pgs-1. Genital sclerites with a pair of sgs. Three pairs of pgs arranged around GO ( Fig. 3G View Figure 3 ).
Gnathosoma ( Figs. 4A–C View Figure 4 ) 0.67 times longer than wide; with a pair of basirostral setae. Gnathosomal base with pair of areolae distinctly. One pair of maxillary setae on gnathosomal base, other pair half-way along rostrum. Rostrum triangular, reaching end of P2. Tectum triangular almost reaching end of P-1, Rostrum as long as 0.44 of gnathosoma length. Rostral sulcus long, reaching up to 0.60 of rostral length. Palps are slender and consist of four segments. P1 to P4 lengths 10, 40, 10, 37 respectively. P1 and P3 without setae, P2 with single seta, P4 with three setae at basal whorl. P4 shorter than P2.
All legs ( Figs. 4D–G View Figure 4 ) slender and long but shorter than idiosoma. Telofemora, genua and tibiae with articular membranes; those of tibiae distinctly triangular and pointed. On the surface of telofemora, genua and tibiae I and II foveate. Leg chaetotaxy from trochanter to tarsus (bipectinated setae between parentheses, parambulacral setae and solenidia excluded): leg I: 1, 2, 5, 4, 7(2), 65; leg II: 1, 2, 5, 4, 7(2), 3; leg III: 1, 2, 2, 3, 5(1), 4; leg IV: 0, 2, 2, 3, 5(1), 3. Telofemura I to IV 1.35, 1.56, 1.53 and 1.86 times longer than high, respectively. Tibiae I to IV with 2, 2, 1, 1 bipectinate setae. Tarsi I to IV with 3, 3, 4, 3 dorsal setae and 3, 0, 0, 0 ventral setae. All legs with two lateral claws with accessory process but delicate pectines (except for leg I) (oil immersion) and a small bidentate median claw. Fossa membrane present but small.
Male – Male is similar to female except for the genital plate ( Fig. 3C View Figure 3 ). GO surrounded by 31–33 pgs. Genital sclerites with five pairs of sgs; anterior pairs hair-like, posterior ones spur-like ( Fig. 3J View Figure 3 ). GO 42 long, 30 wide. Distance between edges of GA and GO 85, equalling 0.48 of GO length. Spermatopositor large (109) but not extending anterior margin of GA ( Fig. 3I View Figure 3 ).
Juvenile – Unknown
Remarks
This species was described by Bartsch (1976) based on specimens collected from the upper littoral zone among sediments in the Bay of Arcachon, France. Specimens from France exhibit a sharper posterior margin on the ocular plate. In this study, the species is reported for the first time from Fethiye , Muğla, Türkiye (Levantine Sea, Mediterranean), far from its type locality .
