106 NATURA SOMOGYIENSIS The new species was compared to those Neuroleon species (12) found in Arabian Peninsula ( ASPÖCK et al. 2001), it can be distinguished to each of two or more different characters, such as size, pattern and shape of pronotum, venation and pattern of wings, length of tibial spurs, pattern of abdomen, genitals. Neuroleon amseli Holzel, 1983 closely resembles N.fuscus sp. n. but frons and pronotum pattern are different and length of tibial spurs shorter than that of new species. Further 12 Neuroleon taxa (N. alexandrei (Navás, 1912), N. bronzii (Navás, 1931), N. caligatus (Navás, 1921), N. dancalica (Navás, 1931), N. pulchellus (Banks, 1911), N. punctatus (Navás, 1911), N. retialis (Navás, 1931), N. sansibaricus (Navás, 1913), N. signata (Navás, 1917), N. striatus (Navás, 1914), N. torridus (Navás, 1914), N. tristictus (Navás, 1936) from East Africa ( STANGE 2004) were compared to the new species. Based on its size, venation and pattern of wings, branches of radius sector, number of cross-veins before origin of Rs, pattern of abdomen N. bronzii (Navás, 1931), N. retialis (Navás, 1931), N. striatus (Navás, 1914) are closely related species to the new species. Pronotum pattern of N. bronzii (Navás, 1931) and N. retialis (Navás, 1931) are different from that of the new species. N. striatus (Navás, 1914) has longer wings and number of branches of radius sector more than that of the new species. Creoleon mortifer (Walker, 1853) Material examined: YEMEN Island C.

Zoogeographical remarks Socotra needs special attention in zoogeographical view, since found in transition zone between Eathiopian and Palearctic realms and separated from the African continent more than 20 million years ago. So far, 13 Myrmeleontidae and 1 Ascalaphidae and species have been found (KIMMINS 1960, WHITTINGTON 2002, ÁBRAHÁM 2010). The proportion of the endemic species is high, approximately 40%: (Echthromyrmex insularis Kimmins, 1961, Centroclisis lineata (Kirby, 1903), Myrmeleon saldaitisi Ábrahám, 2010, Neuroleon socotranus (Taschenberg, 1883), Neuroleon fuscus sp. n.). The other species are also occurring in Africa. Some of them have wide distribution or their distribution is restricted only to East-Africa. No typical Asian or Arabian species were recorded from Socotra. Although, Cueta klugi Holzel, 1982 and Myrmeleon pellucidus Holzel, 1988 species were described from the Arabian Peninsula, most likely they are also colonised Socotra from the African continent. The only known Aschalaphidae species, Ascalaphus aethiopicus (Kimmins, 1949) also confirms the African origin of the fauna of Socotra ( ÁBRAHÁM 2010).
