Female (holotype): Idiosoma elongated L/W 347/241; coxal field L/W 138/188; Cx-I separated medially; suture lines Cx-II/III and Cx-III/IV complete; posterior margin of Cx-IV without medial apodemes, lateral apodemes shortened and broad (Fig. 1A). Genital field L/W 67/34, gonopore elongated, pregenital sclerite small (W 27), postgenital sclerite bowed, with a pair of wheel-like acetabula (Fig. 1A). A pair of small platelets with coxoglandularia 4 and associated setae free in the integument posterior to postero-lateral apodemes of Cx-IV.

The new species resembles Litarachna gracilis Pešić, 2013 due to the absence of medial apodemes of Cx-IV, the presence of a ventral projection on P-2 and the peg-like seta on P-4. The latter species, described from South Korea (Pešić 2013a), is a characteristic inhabitant of marine interstitial (as indicated by the absence of eye pigment) and can be distinguished by a number of features: suture lines Cx-II/III and Cx-III/IV incomplete, gonopore more elongated, a different arrangement of wheel-like acetabula with the the anterior pair positioned on the level of postgenital sclerite, and two posterior pairs almost touching each other, and P-4 ventral setae approached to the distoventral edge of the segment (Pešić 2013a).</p><p>Litarachna enigmatica also resembles to L. smiti Pešić, Chatterjee &amp; Ahmed Abada, 2008 from the Red Sea (Pešić et al. 2008a, b), L. bartschae Smit, 2003 from Australia and Brunei (Smit 2003, Pešić et al. 2013b) and L. madagascariensis Pešić, 2013 from Madagascar (Pešić 2013b) in having a ventral projection on P-2 and the peg- like seta on P-4. However, the new species can be easily distinguished from them by the lack of a setal tubercle on P-4 and completely reduced medial apodemes of Cx-IV.</p><p>Moreover, the new species is unique within the genus Litarachna in the postgenital sclerite having a pair of wheel-like acetabula, a character found only in the females of Pontarachna . As pointed out by Cook (1996), in males of Pontarachna and both sexes of Litarachna no wheel-like acetabula are present associated with the genital sclerites. Anyhow it is worth to mention that the structure of the so-called wheel-like acetabula associated with the postgenital sclerite should be determined under scanning electron microscope (SEM). Unfortunately, with the single specimen of our study this was not possible.</p><p>Distribution.

The species is named for its presence in Antalya.</p><p>Remarks. Litarachna antalyaensis belongs to the L. duboscqi —species group (see Pešić et al. 2008c). Litarachna duboscqi is a widely distributed species in the Mediterranean Sea (Walter 1925) and can easily be distinguished from the new species in the glandularium-like structure posterior to the fourth coxal plates fused with the adjoining coxoglandularia 4 (compare Fig. 2E with Fig. 2F).</p><p>Due to the medially separated first coxal plates and the glandularium-like structure posterior to Cx-IV not fused with adjoining coxoglandularia 4, the new species resembles Litarachna hongkongensis Smit, 2002, from Starfish Bay, Hong Kong (Smit 2002), L. marshalli Wiles, Chatterjee &amp; De Troch, 2002 from the Indian Ocean (Wiles et al. 2002), L. lukai Pešić, 2013 from the marine interstice of the South Korean coast of the Yellow Sea (Pešić 2013a) and L. sagamiensis Moto &amp; Abé, 2013 from the Pacific coast of Japan (Moto &amp; Abé 2013). Litarachna sagamiensis differs from the new species in the higher mumber of perigental setae around the male genital field (49–71, data taken from Moto &amp; Abé 2013) and the glandularium-like structure and adjoining coxoglandularia 4 located posteriorly to posterolateral apodeme of Cx-IV (Moto &amp; Abé 2013). Litarachna lukai is characterized by the reduced ocular pigment and ventrodistal edge of P-2 ending in a pointed extension (Pešić 2013a). Litarachna hongkongensis is similar to the new species in having about ten pairs of perigental setae in the male but differs from the latter in a less elongated genital field in the female with the genital sclerites almost touching each other and much longer medial posterior apodemes of Cx-IV in both sexes (see Smit 2002). Litarachna marshalli can be distinguished from the new species in the male genital field having only three pairs of perigenital setae (Wiles et al. 2002).</p><p>Biology. One ovigerous female from our material contained one large egg with a maximum diameter of about 120 µm.</p><p>Distribution.
