This also holds problems. According to EASIN, it is cryptogenic, according to Galil & Goren (2014) it is alien. It may presumably depend on to which species belongs Mediterranean specimens...if to 


Bregmaceros atlanticus Goode & Bean, 1886

or to:

Bregmaceros japonicus Tanaka, 1908

The origin of the Mediterranean records is unknown. Its finding in Israel does not classify it as 'alien' - see comments below
This circumtropical species has been reported from the eastern Atlantic (from Madeira to South Africa), western Atlantic (from New Jersey through the Gulf of Mexico to Guianas), Indian Ocean (South Africa and Mozambique Channel to the Arabian Sea) and from southern Japan (D’Ancona & Cavinato, 1965).
The recent finding of the specimens in relatively shallow waters off the Israeli and Turkish coasts raises the question of their origin. The antenna codlets’ presence could be accounted for by one of the following possibilities: (a) they are part of a small native population in the Mediterranean; (b) they were introduced from the Red Sea through the Suez Canal; (c) they were discharged, as larvae or post larvae, with ballast water.We deem it highly unlikely that members of a distinctive genus inhabiting shallow, heavily exploited zones had been collected only once in the western Mediterranean (D’Ancona & Cavinato, 1965), and then recurrently within a short time frame in the Levant Sea. Considering its wide distribution, we cannot exclude the possibility that B. atlanticus is present in the Red Sea, in addition to the three Bregmaceros species already reported (Goren & Dor, 1994), and may have entered the Mediterranean through the Suez Canal as so many other fish species (Goren & Galil, 2005). However, the presence of the Israeli specimens 25 km from the port of Ashdod in the direction of the prevailing coastal current, and the Turkish specimens in Antalya Bay, raises the possibility that the fish arrived in the Mediterranean with discharged ballast water.

Yes, totally agree by myself too, unknown origin and unknown status

Unknown status = questionable? cryptogenic?

It seems as cryptogenic

The status Cryptogenic will be maintained for this species in the EASIN CAtalogue.
