YEMEN : SOCOTRA ISLAND: 1 J, Dixam plateau, wadi Zerig, pools, Juncus marsh, 12°29.6ʹN , 53°59.5ʹE , 655 m , 13.–14.vi.2012 , J. Bezděk, J. Hájek, V. Hula, P. Kment, I. Malenovský, J. Niedobová & L. Purchart leg. ( NMPC ). Notes. Identification of this species has been verified by Olof Biström (Helsinki, Finland ). The single Socotran male slightly differs from the African specimens in shape of median lobe (O. Biström, pers. comm. 2014). However, as the variability in median lobe is known also in African population of the species (O. Biström, pers. comm. 2014), and only a single specimen is known from Socotra , we prefer to maintain the species as L. continentalis . Habitat. The single specimen recently collected in Socotra came from a large pool surrounded with Juncus sp. marsh in a wadi ( Fig. 14 ). Distribution. A species known from southern Africa, and eastern Africa north to Somalia ( GUIGNOT 1959 , OMER- COOPER 1965). First record from Yemen ( Socotra Island ).
