186 NATURA SOMOGYIENSIS Genitalia: Male. In lateral view (Fig. 11 A), tergite 9 sub-rhomboid-shaped, yellow with short sparse white hairs. Ectoproct wide oval with black hairs on distal and ventrocaudal margins. Sternite 9 elongate with at least 3x longer caudal hairs than those on ectoproct. Gonarcus, parameres and mediuncus as in Fig. 11. B and C. Paratypes $ Forewing: 29-30 mm long, 7.5 mm wide. Hind wing: 26-27 mm long, 6.5 mm wide; abdomen 22 mm long. Female genitalia in ventral view as in Fig. 11 D. Myrmeleon alternans Brullé in Webb & Berthelot, 1839 is an endemic species of Azores Archipelago. The closely related species, Myrmeleon fasciatus (Navás, 1912) (Fig. 8) is spreading from West Sahara to Arabian Peninsula. The new species is not conspecific with Myrmeleon alternans Brullé in Webb & Berthelot, 1839 which is mentioned from Socotra by KIMMINS (1960) and WHITTINGTON (2002). Based on male genitalia, the new species belongs to the fasciatus-group (M alternans Brullé in Webb & Berthelot, 1839, M. fasciatus Navás, 1912, M. pseudofasciatus Holzel, 1980) with uniform and unseparable male genitalia ( H OLZEL 1980). General colour of Myrmeleon fasciatus is reddish brown and smaller than the new species. Pattern on pronotum is rather indistinct and different from that of the new species (Figs. 9 and 10). Dashes on longitudinal veins are very short but they are approximately equal and yellow and brown dashes alternate each other on wing of Myrmeleon saldaitisi sp.n. Anal area of fore wing of the new species with 4-5 cells in two rows between A 1 and anal margin. In M. fasciatus, there are only 2-3 cells in two rows. Most of the Myrmeleon without any Banksian-lines but in the new species, posterior Banksianline or its trace is clearly noticeable. Type material of Nemeyus sanaanus Navás, 1929 from Yemen lost ( A SPÖCK et al. 2001). Based on Navás's description, it is combined to Myrmeleon sanaanus (Navás, 1929) by S TANGE (2004). The proposal combination is confirmed by base of fore wing and pillula axillary of hind wing ( N AVÁS 1929 in Fig. 6). In both species, patterns of pronotum and vertex are different from that of the new species. Etymology: the new species is dedicated to Dr. Aidas Saldaitis (Lithuanian entomologist). Myrmeleon hyalinus isolatus ssp. n. WHITTINGTON 2002 as Myrmeleon sp. near hyalinus Olivier, 1871 Material examined: 1$ Island W. Sokotra, Shuab loc., coast line mangroves 24. 03. 2009. Leg. Saldaitis. The holotype is deposited in the entomological collection of Somogy County Museum. Frons with small shinning dark brown spot. Clypeus with two indistinct, rounded, light brown spots. (Fig. 12 A). Pronotum with narrow brown central strip and dark brown lateral spots (Fig. 12 B). Fore wing: 19 mm, hind wing: 17 mm long. Venation yellow with tiny dark brown spots, basal half of Sc and R, M with dark brown dashes at cross-veins. In apical part of fore wing, end parts of radial veins dominantly dark brown (Fig. 13). Myrmeleon hyalinus is a widespread species in the Saharan and Sub-Saharan zones. It is not uniform species morphologically within distribution area, divided four subspecies by H OLZEL (1986). The locus typicus of M. hyalinus hyalinus Olivier, 1811 can be found in the Arabian Peninsula. The new subspecies come from the island of Socotra is distinguished by smaller size and especially tiny dark brown spotted veins of wings and isolated population.
