ETYMOLOGY: The specific name, a noun, refers to the armament of its chelicerae.
DIAGNOSIS: The species is characterised by the shape of the embolic division and by a very long median membrane.
DESCRIPTION: Male paratype. Total length 1.51 (holotype 1.68). Carapace unmodified, 0.75 long, 0.58 wide, brownish yellow. Chelicerae 0.38 long, with a toothlike process as in Fig. 70. Maxillae each with a stout tooth anteriorly. Legs yellow. Leg I 2.19 long (0.63+0.18+0.55+0.48+0.35), IV 2.10 long (0.60+0.18+0.57+0.45+0.30). Chaetotaxy: 2.2.1.1, length of spines about one or two diameters of segment. TmI 0.35. Metatarsus IV without trichobothrium. Palp (Figs 71-74): Tibia unmodified. Protegulum membraneous, almost transparent. Distal suprategular apophysis sharpened distally. Median membrane like a long, narrow, almost transparent band, scarcely visible. Embolic division complex, with a large pointed anterior radical process and several small outgrowths. Embolus proper short and hook-shaped. Abdomen 0.75 long, 0.50 wide, pale grey.
Female. Total length 1.55. Carapace 0.75 long, 0.50 wide. Chelicerae 0.28 long, unmodified. Maxillae without a stout tooth. Leg I 1.99 long (0.60+0.20+0.53+0.43+ 0.23), IV 2.11 long (0.63+0.18+0.55+0.45+0.30). TmI 0.35. Abdomen 0.82 long, 0.50 wide. Epigyne and vulva as in Figs 75 & 76. Body and leg coloration, as well as chaetotaxy, as in male.
TAXONOMIC REMARKS: The new species differs clearly from the single known congener, J. falconeri (Jackson, 1908), by the presence of a stout tooth on the maxillae, by a well-developed distal suprategular apophysis, by a bigger and more complex embolic division, as well as by the shape of the epigyne.
DISTRIBUTION: Known from the islands of Cyprus and Samos only.
