A single specimen collected in 1924 from Port Said harbour, Egypt, was hitherto the only record of the species in the Mediterranean Sea. The cluster of specimens documented herein suggests the species has recently established a population along the southern Levantine coast. Key words: Lucifer hanseni, Decapoda, Erythrean alien, Mediterranean, Israel Introduction Material and methods The Levantine littoral biota has an ever The GOC Several samples were collected in increasing component of Erythrean aliens (Galil 2008–2011 along the Mediterranean coastline of 2009). Many of these have spread westwards, Israel: off Herzlia, 2.05.2011, depth 11–13 m, 9 some reaching the western Mediterranean specimens (2♀, 3♂, OUMNH.ZC.2012. 04.0001, (Sánchez-Tocino et al. 2007; Daniel et al. 2009). remainder in RE collection); off Maagan A considerable proportion of these are Michael, 14.04.2011, depth 5 m, 1 specimen (RE crustaceans, with Galil (2011) listing 106 alien collection); northeast of Ashdod, 31°56.389N species in the Mediterranean. Four fifths of these 34°41.76E, 09.09.2008, depth 10.8 m, 1 ♀ (TAU are derived from the Indo-Pacific, 64 of which AR 29049); northeast of Ashdod, 31°51.028N 34°39.026E, 04.09.2011, depth 9 m, 4 ♀, 3 ♂ can be directly traced as having invaded the (TAU AR 29053); northeast of Asdod, Mediterranean through the Suez Canal. 31°57.586N 34°42.322E, 09.09.2008, depth 10.5 Decapoda are particularly well represented m, 1 ♀ (TAU AR 29050); northeast of Ashdod, with 70 species (Galil 2011), although not all 31°58.110N 34°40.369E, 07.09.2011, depth 35 have established viable populations in the m, 1 ♀ (TAU AR 29051); northeast of Ashdod eastern Mediterranean and some are only known 31°55.747N 34°39.118E, 07.09.2011, depth 35 from a single record. One such species is Lucifer m, 1 ♀ (TAU AR 29052). Specimens are hanseni Nobili, 1905 (Balss 1927).

Discussion Prior to the present records, the only record of Lucifer hanseni in the Mediterranean is by Balss (1927) who recorded the species from Port Said, based on material collected during the Figure 1.

This record has been variously treated in C, uropods. subsequent literature: Galil et al. (2002) consi- dered it as having “only a single reliable record”. Similarly, Zenetos et al. (2005) considered it as a Results “casual” species, i.e., presumed not to be established. However, Holthuis and Gottlieb Family Luciferidae De Haan, 1849 (1958) state that the identification of this Lucifer hanseni Nobili, 1905 (Figure 1) material is not certain, referring back to Balss Lucifer hanseni Nobili, 1905: 395; 1906: 25-27; (1927).

Males of Gurney (1927b), who himself took part in the both species can be easily separated on account Cambridge Expedition, when discussing the of the larger, recurved anterior process on the larval development of the species, mentions that sixth abdominal segment in L. typus (vs. smaller, the doubt expressed in Balss (1927) stems from non-recurved in L. hanseni) as well as the the fact that the males sent to Balss were comparatively much longer eyestalks in L. typus apparently lost in the post. Gurney (1927b) also (Petit 1973). As females lack the processes on states that males were rare in the plankton the sixth abdominal segment, identification is samples collected during the expedition, but that more difficult, although the comparative length the two available adult males and two nearly of the eyestalk can be used. Further details to adult males match the description in Hansen separate both species can be found in Hansen (1919) and there can be no doubt as to their (1919), Petit (1973) and Naomi et al. (2006). identity. Evidently, more material collected 106 Records of Lucifer hanseni from the Mediterranean coast of Israel during the expedition was available to Gurney taxa, such as copepods, L. hanseni and mysids (1927a, b) and Fox (1927) than Balss (1927), are likely inactive during the day, sinking to near even if some was indeed lost in the post (see the bottom during the day and becoming active Gurney 1927b) or perhaps not all was forwarded at night, spreading throughout the entire water to be identified by Balss. The picture which column, with those emergence cycles further emerges from this historical account suggests influenced by tidal and lunar cycles. Such an that only one species of Lucifer, viz.
