            <p> Etymology. From the Greek palaios for ‘old’, in reference to this being an early member of the family  Synaxidae . </p>
            <p>Diagnosis. Carapace small, oval, tubular; cervical groove V-shaped centrally; carapace densely covered with coarse, blunt, forwardly directed tubercles, most robust on two postrostral ridges on anterior part.</p>

            <p>Diagnosis. As for genus.</p>
            <p> Repository of the type specimen. MAB -  Oertijdmuseum , Boxtel, The Netherlands. </p>
            <p> Type material.   The holotype MAB13942, and sole specimen known to date, is an incomplete carapace with a maximum preserved length of 9.5 mm and a maximum preserved width of 6.0 mm, collected in June 2013 by one of us (À.O.) during a field trip to the 5th  Symposium on Mesozoic and  Cenozoic Decapod Crustaceans , Kraków (Poland).  Etymology. Dedicated to Montserrat Batet, partner of one of us (À.O.), as a token of thanks for her support and understanding. </p>
            <p> Locality and stratigraphy. A road cutting on a small hill close to the village of Szklary, southern Poland, exposing upper middle Oxfordian (  Gregoryceras transversarium ammonite Zone) reefal strata (Figures 1, 2). </p>
            <p>Description. Carapace small, oval, tubular, convex in transverse section; base of rostrum broad, tuberculate and concave; cervical groove Vshaped centrally, obscure laterally; carapace densely covered with coarse, blunt, forwardly directed tubercles, most robust on two postrostral ridges on anterior part; another less pronounced ridge of tubercles extending centrally on mesogastric with double circular tubercle arrangement forming a figure 8 on mesogastric area; cervical groove forming wide V in central third of carapace and extending obliquely (c. 45 degrees) toward anterolateral border; posterior part of carapace densely covered with coarse, blunt, forwardly directed tubercles, largest around cervical groove; maximum length of preserved posterior part about 35 per cent of total preserved carapace length.</p>
            <p> Remarks. The type of ornament, general shape of the anterior carapace and length of the posterior portion, rules out assignment to the families  Palinuridae ,  Cancrinidae , or  Scyllaridae and places the present Late Jurassic taxon in the  Synaxidae . The two postrostral ridges of larger tubercles on the anterior carapace of  Palaeosynaxes nov. gen. could be taken as a prelude of the postfrontal horns of members of the  Palinuridae . These two rows of forwardly directed tubercles and the subcircular tubercular arrangements on the central gastric area make  Palaeosynaxes nov. gen. easily differentiated from all other known synaxids. </p>
            <p> The Middle Triassic  Yunnanopalinura schrami Feldmann, Schweitzer, and Zhang in Feldmann, et al., 2012 shows some similarities to synaxids according to Feldmann et al. (2012), but a more detailed comparison is impossible because the Chinese taxon is based on two specimens in which preservation of parts of the cephalothorax is too poor (Fraaije et al., 2020). </p>
