New records of 19 species of myrmeleontoid lacewings (Neuroptera: Myrmeleontidae, Ascalaphidae, Nemopteridae) of Armenian fauna are presented. In comparison with adjacent Caucasian countries Armenian fauna of antlions, spoonwings and owlflies could be characterized as manifold, organized under the influence of Anatolian faunistic center. Distoleon laticollis (Navás, 1913), Delfimeus irroratus iranensis (Hölzel, 1972), D. irroratus morgani (Navás, 1913), Neuroleon tenellus (Klug in Ehrenberg, 1834), Creoleon griseus (Klug in Ehrenberg, 1834), Libelloides macaronius kolyvanensis morpha alba Krivokhatsky, Bagaturov et Prokopov, 2018 are reported for Armenia for the first time. Here we proposed a new status for three taxa, which are interpreted as subspecies of Delfimeus irroratus (Olivier, 1811): D. irroratus morgani stat. n., D. irroratus iranensis stat. n. and D. irroratus friedeli (Hölzel, 1972), stat. n. All four taxa (including the nominotypical subspecies) differ in the pronotum pattern and the color of wings and have a partially sympatric distribution. The largest representatives (forewing 25 mm) nominotypical subspecies and a small subspecies D. irroratus friedeli with dense venation were not found in Armenia.

Since the first information at the end of the 19th Century and up to the present time, the only species of the family Ascalaphidae has been registered in Crimea: Libelloides macaronius (Scopoli, 1763) with two subspecies, L. macaronius kolyvanensis (Laxmann, 1770) (= Ascalaphus longicornis dubius Eversmann, 1850, syn. n.) and L. macaronius pupillatus (Rambur, 1842). Each listed subspecies has two colour morphs. Yellow (morpha typica) and white (morpha alba n.) morphs of the subspecies L. macaronius kolyvanensis (Laxmann, 1770) сan be found together in south-east part of Crimea. The second subspecies with two colour morphs, L. macaronius pupillatus (Rambur, 1842) morpha typica and morpha intermedia (Menétriés, 1849), is definitely extinct in Crimea and occurs now in the Kuban and the Volga regions. Subspecific and infrasubspecific structure of Libelloides macaronius is discussed. The key to all subspecies from the Ancient Mediterranean zoogeographical region is given. Information about their bionomics, distribution and occurrence in Crimea over the past 100 years are added. Brief diagnoses of taxa and descriptions of L. macaronius kolyvanensis alba, morpha n. is given. The rank of two species is changed: Libelloides macaronius tajikus Luppova, 1973, stat. n. and L. macaronius oculatus (Brullé, 1832), stat. n. = Ascalaphus kolyvanensis var. ponticus McLachlan, 1876, syn. n. Two subspecies are reduced to morphs: Libelloides longicornis (Linnaeus, 1764), morpha leucocelia Costa, 1855; Libelloides macaronius pupillatus (Rambur, 1842) morpha intermedia Ménétriés, 1849. Some ascalaphid taxa from the Central Palaearctic are interpreted as subspecies of Libelloides macaronius described on the base of typical yellow morphs: L. macaronius turсestanicus (Weele, 1909) and L. macaronius trimaculatus (Weele, 1909). In addition, two white morphs, L. macaronius turcestanicus doboszi morpha n. and L. macaronius trimaculatus letardii morpha n., are described. White morpha was not found for L. macaronius tajikus Luppova, 1973, stat. n. Among Asian taxa, the specimen described by L. Navás as variation, transferred here to the rank aberration Libelloides macaronius kolyvanensis ab. fumata (Navás, 1929), which does not form the biological taxon.

Faunistic data on eight species of Chrysopidae (Neuroptera) from Republic of Sakha (Yakutia) and Magadan Region are reported. Chrysopa dasyptera McLachlan, 1872 is newly recorded from these regions, and Ch. abbreviata Curtis, 1834 from Yakutia. The northern limit of the range of Chrysopidae is discussed. It is noted that this limit is shifted much further south in Asia (especially in the northeast) than in Europe and North America.

Nohoveus gnezdilovi Krivokhatsky, sp. n. and Subgulina vanharteni Krivokhatsky, sp. n. from Sharjah Desert Park of United Arab Emirates are described. The generic affiliation for Myrmecaelurus laetus (Klug, 1834), Myrmecaelurus persicus (Navás, 1929) and Nohoveus fidelis Hölzel, 1968 were established on the base of male gonarcus description

The distribution of antlions on larval and pupal stages with water streams in Turan and Baikal Region is discussed. Pupae in cocoons and larvae have some morphological adaptations for survival in water conditions during settling. The radiation with using of wind and water stream is proposed to name feng-shui type of settling (wind-stream). This model of settling has been helpful for an explanation of recolonization of Myrmeleon frontalis Burmeister, 1839 onto oceanic islands after tsunami on the example of volcanic explosion on Krakatau

Fauna of Neuroptera, Myrmeleontidae of Daghestan includes 17 species. The distribution of species among landscapes is discussed
