The male of Ixodes tapirus Kohls, 1956 (Acari: Ixodidae) is described for the first time and the female is redescribed in greater detail. Adults of I. tapirus are similar to those of Ixodes guatemalensis Kohls, 1956, Ixodes lasallei Méndez & Ortiz, 1958, Ixodes montoyanus Cooley, 1944 and Ixodes venezuelensis Kohls, 1953 but can be distinguished by their overall size, the amount of sclerotisation of the conscutum and accessory plates, the shape of the scutum, the number of punctations and their pattern on the conscutum and scutum, the depth of the punctations on the basis capituli dorsally, the shape and size of the porose areas and the size and shape of the auriculae. Adults of I. tapirus were collected from tapirs and vegetation in the mountains of Colombia, Panama and recorded from Costa Rica for the first time.     

Description of a new species of <Emphasis Type="Italic">Amblyomma</Emphasis> Koch, 1844 (Acari: Ixodidae), parasite of deer (Artiodactyla: Cervidae) and wild pigs (Artiodactyla: Suidae) in the Philippines

Amblyomma anicornuta n. sp. (Acari: Ixodidae) is described based on adults and nymphs ex deer (Artiodactyla: Cervidae) and wild pigs (Artiodactyla: Suidae) from Luzon, Philippines. Adults of A. anicornuta n. sp. are similar to those of several Asian and Australasian species of Amblyomma Koch, 1844 with a 4/4 dental formula on the hypostome but can be distinguished by the colouration and pattern of punctations on the conscutum in the male and scutum in the female, the absence of a marginal groove on the conscutum in the male, the possession of long, thick, prominent setae on the alloscutum in the female, projections on anal valves and sclerotised ring around them in the male, a large median sclerite ventrally in the male, as well by the shape of the genital aperture in the female and the size and shape of spurs on coxae I–IV in both sexes. The nymph of A. anicornuta n. sp. is somewhat similar to that of A. babirussae Schulze, 1933 and A. geoemydae (Cantor, 1847) but can be distinguished by the colouration pattern on the scutum, the presence of dorsal cornua and the size of the spurs on coxae I–IV.     

Description of a new species of <Emphasis Type="Italic">Ixodes</Emphasis> Latreille, 1795 (Acari: Ixodidae) and redescription of <Emphasis Type="Italic">I. priscicollaris</Emphasis> Schulze, 1932, parasites of New Guinea rodents (Rodentia: Muridae)

A description of the larvae of <Emphasis Type="Italic">Cinygmula unicolorata</Emphasis> Tshernova, 1979 and <Emphasis Type="Italic">Cinygmula malaisei</Emphasis> (Ulmer, 1927) (Ephemeroptera,Heptageniidae) from the Russian Far East

The larvae of Cinygmula malaisei (Ulmer, 1927) and Cinygmula unicolorata Tshernova, 1979 from the Russian Far East are described and illustrated. The larva of Cinygmula unicolorata is similar to those of Cinygmula putoranica Kluge, 1980 and Cinygmula uyka Gorovaya et Tiunova, 2013 but differs from the larva of C. uyka in the absence of gill filaments and from that of C. unicolorata in the shape of the first gill (tergalia). The upper outer margin of the first gill is rounded in the larva of C. unicolorata and almost straight in C. putoranica; the gills of C. unicolorata are matte and the trachea is poorly expressed, in contrast to the distinctly brown trachea of C. putoranica. The larvae of Cinygmula malaisei are similar to those of C. irina and C. autumnalis but differ from the latter in the presence of gill filaments. The larva of C. malaise differs from that of C. irina in the rounded outer margin of the first gill, the shape of gills VI and VII, and in the size of the leg segments.     

New species of the tenebrionid genus <Emphasis Type="Italic">Menimus</Emphasis> sharp, 1876 (Coleoptera,Tenebrionidae) from southern Palaearctic

Three new species of the genus Menimus are described from Yunnan Province, China. Over 70 species of Menimus are distributed in the tropical and subtropical zones from India to Oceania and New Zealand. A new subgenus, Sinomenimus subgen. n., is erected with the type species M. kabaki sp. n. characterized by the absence of eyes and by the presence of the spermatheca and sharp depression at the posterior margin of the thoracic metasternite. The following new synonymy is established: Menimus Sharp, 1876 = Neomenimus Kaszab, 1939, syn. n., with the following new combinations resulting: Menimus clavatus (Kaszab, 1939) = Neomenimus clavatus Kaszab, 1939, comb, n.; Menimus biroi (Kaszab, 1939) = Neomenimus biroi Kaszab, 1939, comb, n.; Menimus setosus (Kaszab, 1939) = Neomenimus setosus Kaszab, 1939, comb, n.; Menimus brevissimus (Kaszab, 1939) = Neomenimus brevissimus Kaszab, 1939, comb. n.     

New species of the bristletail genus <Emphasis Type="Italic">Allopsontus</Emphasis> Silv. (Microcoryphia,Machilidae) from Southeastern Kazakhstan and Abkhazia

Two new bristletail species, Allopsontus (Anisoptinus) nigrus sp. n. from Southeastern Kazakhstan and A. (Kaplinilis) abkhazicus sp. n. from Abkhazia, are described. A. nigrus sp. n. differs from the only other known species of the subgenus Anisoptinus, A. borgustani Kaplin 2015, in a number of characters, namely, in more rounded paired ocelli, an extended apical segment of the labial palpus, a long articulated ovipositor, and in the absence of short appressed pigmented setulae on the maxillary and labial palpi in males. A. abkhazicus sp. n. can be easily distinguished from all the other known species of the subgenus Kaplinilis by the absence of short appressed pigmented setulae on the maxillary and labial palpi in the males, the absence of a projection with numerous spiniform setae on the male fore femur, and in shorter male genital appendages. The ocellus of the male and female is 2.8-2.9 times as wide as long; the length to width ratio of the eye is 0.9-1.0; the ovipositor consists of 60 divisions.     

New scarab-beetle species (Coleoptera,Scarabaeidae, Aphodiinae,Orphninae) from Central Asia and Southern Africa

Three new scarab-beetle species are described. Aphodius moronensis sp. n. (northern Mongolia) and A. kozlovi sp. n (eastern Tibet) with modified spurs on fore tibiae in males are placed in the falcispinis group of the subgenus Agolius but are similar to the grafi group of the subgenus Chilothorax in the shape of parameres and elytral pattern. The new species differ from A. falcispinis in the shape of the spur; A. moronensis sp. n. also differs in the shape of the body and parameres. Orphnus transvaalensis sp. n. is the second apterous Orphnus species found in Southern Africa. It differs from the closely related O. harrisoni in the shape of parameres, position of the hornlike clypeal process, and in a smaller body size.

New data on the taxonomy,distribution, and ecology of the weevil genus <Emphasis Type="Italic">Otiorhynchus</Emphasis> germar (Coleoptera,Curculionidae)

The subgenus Pocusogetus Rtt. of the genus Otiorhynchus Germ. is revised. The subgenus includes O. rosti Strl., O. shapovalovi Davidian et Yunakov, O. obsulcatus Strl., O. fischtensis Rtt., and O. gusakovi sp. n. closely related to O. fischtensis (both from Mt. Fisht, the Western Caucasus). O. fischtensis is transferred from the subgenus Vicoranius Rtt., its lectotype is designated. A key to species of Pocusogetus is given. The systematic position of the subgenera Pocusogetus and Vicoranius in the genus Otiorhynchus is discussed. New data on the geographical distribution and ecology of the little-known species of the subgenera Obvoderus Rtt., Pseudoprovadilus Magnano, and Clypeorhynchus Yunakov et Arzanov are given.

Description of a new species of <Emphasis Type="Italic">Ixodes</Emphasis> Latreille, 1795 (Acari: Ixodidae) and redescription of <Emphasis Type="Italic">I. lasallei</Emphasis> Méndez &amp; Ortiz, 1958, parasites of agoutis and pacas (Rodentia: Dasyproctidae,Cuniculidae) in Central and South America

Ixodes bocatorensis n. sp. (Acari: Ixodidae), is described based on adults ex agoutis (Rodentia: Dasyproctidae), pacas (Rodentia: Cuniculidae) and “tapir and sloth” (Perissodactyla: Tapiridae and Pilosa) from Colombia, Panama and Venezuela. Adults of I. bocatorensis n. sp. are similar to those of I. lasallei Méndez & Ortiz, 1958 but can be distinguished by the scutum dimensions, punctation pattern, gnathosoma and palpi measurements and their ratios, basis capituli anterior angle and shape of the spur of palpal segment I ventrally. For comparative purposes the female of I. lasallei is redescribed and the true male of this species is described for the first time. Studied adults of I. lasallei were found on agoutis, pacas and ocelot (Carnivora: Felidae) in Colombia, Peru and Venezuela.

Otiorhynchus iranensis Magnano, 2004 is transferred from the subgenus Protarammichnus Voss, 1960 to the subgenus Pseudotiorhynchus. Lectotype of O. conicirostris Stierlin, 1886 is designated. A key to 15 species of the subgenus Pseudotiorhynchus is given. The new subgenus Microhanibotus Savitsky et Davidian, subgen. n. is established for the new species O. ghilarovi Davidian et Savitsky, sp. n. from the Western Kopet Dagh in Turkmenistan. Microhanibotus subgen. n. is closely related to the subgenera Pseudotiorhynchus, Hanibotus Reitter, 1912 and Nubidanus Reitter, 1912.     

First Record of the Subgenus <Emphasis Type="Italic">Empis</Emphasis> (<Emphasis Type="Italic">Planempis</Emphasis>) (Diptera,Empididae) from Middle Asia,with Description of a New Species

A new species of the subgenus Planempis Frey, 1953 (Diptera: Empididae), Empis (Planempis) gussakovskiisp. n., is described from Tajikistan, being the first record of the subgenus from Middle Asia. The relationships of the new species within the subgenus Planempis are shortly discussed. An updated check-list of Planempis species is provided.     

Taxonomic position of Afghan vole (Subgenus <Emphasis Type="Italic">Blanfordimys</Emphasis>) by the sequence of the mitochondrial <Emphasis Type="Italic">cytb</Emphasis> gene

It is rather difficult to construct a system of gray voles of the tribe Microtini by a set of morphological and karyological characters because form generation is mosaic at these organization levels. The sequence of the mitochondrial cytochrome b gene was used to study the phylogenetic relationships and taxonomic position of the Central Asian subgenus Blanfordimys. Afghan vole Microtus (Blanfordimys) afghanus and Bucharian vole M. (Blanfordimys) bucharensis clustered with Pamir vole M. (Neodon) juldaschi, which is conventionally assigned to another subgenus. The last two species proved to be significantly closer to each other than either of them was to M. (Blanfordimys) afghanus, which disagrees with the monophyletic origin accepted for Blanfordimys. The genetic distances between the species of the subgenus Blanfordmys and M. juldaschi were comparable with the distances between the sister subgenera Microtus s. str. and Sumeriomys or Pallasiinus and Alexandromys and with the basal divergence of supraspecific clades in the subgenus Terricola. It was assumed that a special Central Asian group of species exists within the tribe Microtini and includes species of the subgenus Blanfordimys and M. juldaschi and that the subgenera Neodon and Blanfordimys should be revised.     

A new species of the genus <Emphasis Type="Italic">Nalassus</Emphasis> Mulsant (Coleoptera: Tenebrionidae: Helopini) from the Baltic amber

The first Eocene species of the tribe Helopini, Nalassus klebsi sp. nov., from the Baltic amber is described. The new species is included in the nominative subgenus and similar to the extant species N. dermestoides (Illiger) and N. laevioctostriatus (Goeze), from which it differs in the shape of eyes (eyes are considerably less transverse than in living Palearctic species of the genus Nalassus Mulsant), the shape of the pronotum with acute posterior angles (other Palearctic Nalassus have obtuse or straight pronotal angles) as well as convex elytral intervals. Species of the less specialized nominative subgenus are widespread in forests and (partly) alpine landscapes of Europe (eastwards up to the Urals) and eastern Asia.     

A new species of the genus <Emphasis Type="Italic">Chrysolina</Emphasis> Motsch. (Coleoptera,Chrysomelidae) from the mountains of Tuva and Buryatia

A new leaf-beetle species with two subspecies is described: Chrysolina (Pleurosticha) romani romani sp. et subsp. n. from southeastern Tuva and Ch. romani burjatica subsp. n. from the East Sayan in Buryatia. The habitus of the species is similar to both the representatives of the subgenus Arctolina Kont. and to Chrysolina gebleri L. Medv. from the subgenus Pleurosticha Motsch. The difference between these two closely related genera is discussed and causes to place the new species in the subgenus Pleurosticha, where it can be readily distinguished by the short and wide lentiform aedeagus.     

Poorly known stonefly species, <Emphasis Type="Italic">Isoperla pseudornata</Emphasis> and <Emphasis Type="Italic">Kaszabia nigricauda</Emphasis> (Plecoptera,Perlodidae), from the Eastern Palaearctic

The previously unknown male of Isoperla pseudornata Zhiltzova and nymph of Kaszabia nigricauda (Navás) of the family Perlodidae are described. Sternite VIII of the male of I. pseudornata has no vesicle, the posterior margin is covered medially with strong short brownish setae. Sternite IX forms a subgenital plate. The everted aedeagus is upcurved, turned towards the dorsum, with two rounded lobes and one finger-shaped apical lobe terminating with a membranous funnel depressed medially. The aedeagus membrane is covered with small fine pointed sclerotized spinules; spinules absent on the tip of the funnel. The funnel basally and the finger-shaped apical lobe ventrally are covered with fine pointed sclerotized spinules and rounded sclerotized formations. I. pseudornata differs from the other Eastern Palaearctic congeners in the shape of spots on the head, pronotum, and abdominal tergites. The head of K. nigricauda nymph bears a large brown M-shaped spot forming along the anterior margin two fine stripes widened on the frontoclypeus; the interocular area bears a small pale spot merged with the large transverse W-shaped spot on the occiput. The lacinia is narrowed to the apex, bidentate; the tip of the galea reaches the base of the subapical tooth. The pronotum bears a pale cruciform medial spot, the lateral fields are dark, the lateral margins are pale. The meso-and metanotum exhibit a pale complicated pattern widened to the base of the wing pads. The legs are pale. The abdominal tergites are brown, with a pale transverse stripe widened laterally on the last tergites. Tergite X bears a large pale heart-shaped spot medially. The cerci bear a silky hair fringe dorsally; in the apical part, the apical whorl of cerci has short setae; one ventral and one dorsal seta are longer than the others; the dorsal setae are longer than ventral ones.
