Lasioglossum leptocephalum ( Blüthgen, 1923) View in CoL

Halictus leptocephalus BLÜTHGEN, 1923: 245 View in CoL . Lectotype ♀: Tunisia, Nefta , 14.V.1913 (coll. Blüthgen, MNHUB).

= Lasioglossum sinaiticum BYTINSKI-SALZ & EBMER, 1974: 195 . Holotype ♀: Sinai, Nahal Yam (lagoon of Bardawil ), 1.II.1973, leg. A. Freidberg (coll. Ebmer, in Linz) (not examined).

Paratypes: 3♀, idem ( Linz and col. Bytinsky-Salz) ( 2♀ examined in SMNHTAU), syn. nov .

=? Halictus krugeri BLÜTHGEN, 1930: 222 . Holotype ♂: Libya, Agedabia (SW Tripoli), 20.V.1925, leg. Krüger (MNHUB) (examined). Paratypes: 4♂, idem (MNHUB and R. U. Agrario Bengasi) (examined in MNHUB).

NOTE. WARNCKE (1982: 69) erroneously considered L. leptocephalum as a subspecies of L. albovirens (Pérez, 1895) with a more elongated head and L. sinaiticum as a simple form of L. albovirens leptocephalum . He also placed L. krügeri in synonymy with L. albovirens leptocephalum . The synonymy of L. krugeri remains doubtful and should be confirmed by the discovery of the two sexes in a same locality; it is mentioned here with a "?".

DISTRIBUTION AND ECOLOGY. Lasioglossum leptocephalum occurs in coastal dunes from Tunisia to Israel in the east. The locality in Holot Shunera is a partially stabilized sand dune ecosystem in the Western Negev (Gideon Pisanty, personal communication). In Libya, it has been collected in stabilised sands of the green belt.
