Herpetology Notes, volume 12: 663-666 (2019) (published online on 28 June 2019) First records of Eryx jaculus (Linnaeus, 1758) from Euboea Island, Greece (Squamata: Boidae) Apostolos Christopoulos1,*, Antonios-Georgios Verikokakis2, Vassilis Detsis3, Iraklis Nikolaides4, Leonidas Tsiokos1, Panayiotis Pafilis1,5, and Grigoris Kapsalas1 The genus Eryx Daudin, 1803 (Squamata: Boidae) km2) with a wide variety of habitats ranging from comprises 12 species of sand boas that occur in Africa, dunes to alpine ecosystems. The island became isolated Asia and Europe (Uetz, et al.). The javelin sand boa from the neighbouring central Greece 5,500 years ago Eryx jaculus (Linnaeus, 1758) has a wide distribution (Mariolakos and Bantekas, 2002) from which it is that ranges from North Africa to the Middle East, nowadays separated by a channel (shortest distance: including southeast Europe and the Caucasus region 29.3 m). The herpetofauna of the island comprises a (Teynié, 1997). In Greece, the species can be found total of 30 amphibians and reptiles (Valakos et al., 2008). throughout the mainland, including the Peloponnese, on Surprisingly, the javelin sand boa was not included in many Aegean Islands and on Corfu in the Ionian Sea this list until today. Although Euboea is located very (Lymberakis et al., 2018). The javelin sand boa may close to the mainland and the Cyclades (Fig. 1), both live from the sea level up to 1,500 m (Chondropoulos, hosting populations of E. jaculus, the species has never 1989; Valakos et al., 2008). It prefers dry habitats (rocky been recorded on the island (Boettger, 1891; Werner or sandy hills), semi-desert coastal areas, dunes, light 1938; Chondropoulos, 1989; Valakos et al., 2008). Here, Mediterranean forests, low vegetation shrublands and we report for the first time the occurrence of E. jaculus meadows, cultivated fields and olive groves (Valakos on Euboea, from six different locations. et al., 2008). Though quite common, E. jaculus is hard We deliberately did not include the exact coordinates to detect because of its cryptic lifestyle: it spends most of each record to prevent incidents of illegal collection of its life foraging underground or in burrows and is and trade. The javelin sand boa is one of the very rarely exposed to the ground surface, except during the few European reptiles listed in the Appendix II of breeding season or during dawn and dusk on warmer CITES catalogues that protect species which become periods (Valakos et al., 2008; Speybroeck et al., 2016). endangered or extinct because of international trade. Euboea is the second-largest island of Greece (3,655 On 21 June 2014, an adult individual was observed by LT in south Euboea at the Platanistos area of Ochi Mountain (altitude 436 m). The snake was photographed after dusk while moving through low Mediterranean shrubland (Fig. 2A).

The habitat comprised olive groves and maquis insularity and focused largely on islands (Bedriaga, 1883; shrubland (dominated by Quercus coccifera), Platanus Werner, 1894, 1930; von Wettstein, 1931). Contrary to orientalis clusters, small reedbeds, garrigue and few the insular Greece, the mainland herpetofauna remains almond and walnut trees. The specimens were collected understudied, broad areas have never been surveyed and and deposited at the Natural History Museum of Crete the presence or absence of numerous species therein (NHMC 80.3.114.19, total length: 264 mm; NHMC is merely speculative (Pafilis and Maragou, 2013). 80.3.114.20, total length: 249).
