First description of the male and redescription of the female of <Emphasis Type="Italic">Ixodes tapirus</Emphasis> Kohls, 1956 (Acari: Ixodidae), a parasite of tapirs (Perissodactyla: Tapiridae) from the mountains of Colombia,Costa Rica and Panama

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.     

New species of the Lithobiid genus <Emphasis Type="Italic">Hessebius</Emphasis> Verhoeff, 1941 (Lithobiomorpha,Lithobiidae) from Eastern Kazakhstan

Two new species, Hessebius golovatchi Farzalieva, sp. n. and Hessebius zalesskajae Farzalieva, sp. n., are described based on material from the Dzungarian Alatau Mountains, Eastern Kazakhstan. The female of H. golovatchi sp. n. differs from all the previously known species of the genus in the presence of 3 + 3 spurs on the gonopod, while H. zalesskajae sp. n. is similar to H. perelae Zalesskaja, 1978 but differs in some structural details of the male and female gonopods.     

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.     

Phylogenetic reconstructions in the genus <Emphasis Type="Italic">Capra</Emphasis> (Bovidae,Artiodactyla) based on the mitochondrial DNA analysis

Mitochondrial genome fragments were examined in all species of the genus Capra (Bovidae, Artiodactyla). Phylogenetic analysis was carried out using 59 cytochrome b gene sequences (392 bp), and 22 sequences of the mtDNA variable fragment (402 bp). In the control region, two unique deletions were revealed. One of the deletions was found only in Capra cylindricornis (17 bp), while another one grouped C. caucasica with C. aegagrus (1 bp). The group of Caucasian wild goats splits into two clades, and furthermore, the sequences of C. caucasica demonstrate remarkable similarity to the sequences of C. aegagrus, while C. cylindricornis seems to have evolved independently for a long period of time. It was demonstrated that C. pyrenaica and C. ibex were extremely close to one another. Capra sibirica formed an outer group relative to the other species, and according to our data, was the most ancient species of the genus. On the contrary, genetic distance separating C. falconeri (the most independent species of the genus related to its morphology) from the other species is small.     

Descriptions of eight new species of <Emphasis Type="Italic">Ligophorus</Emphasis> Euzet &; Suriano, 1977 (Monogenea: Ancyrocephalidae) from Red Sea mullets

Eight new species of Ligophorus Euzet &; Suriano, 1977 (Monogenea: Ancyrocephalidae) are described from two species of mullets from the Red Sea. Ligophorus bykhowskyi n. sp. and L. zhangi n. sp. from Crenimugil crenilabris (Forsskål) differ from other species of the genus in the structure of the male copulatory organ, which has a simple accessory piece and a wide copulatory tube that arises from a large, single-chambered, expanded base. Ligophorus simpliciformis n. sp., L. bipartitus n. sp., L. campanulatus n. sp., L. mamaevi n. sp., L. lebedevi n. sp. and L. surianoae n. sp. from Liza carinata (Valenciennes) are differentiated on the basis of the morphometrics of the hard parts of the haptor and male copulatory organ. The eight species represent the first records of species directly attributed to Ligophorus from the Red Sea. Measurements of the haptoral hard-parts and the male copulatory organ of the new species are analysed with the aid of Principal Component Analysis. Three morphological types of male copulatory organ, five types of anchor, and two types of ventral and three types of dorsal bars were distinguished among these species. L. bykhowskyi and L. zhangi from C. crenilabris have the same type of male copulatory organ and anchors. Those species from Liza carinata have only one common morphological character, a thick copulatory tube, but have two types of accessory piece, four types of anchors and three types of bars. All species of Ligophorus found on mullets in the Red Sea have an accessory piece without a distal bifurcation and thus differ from most species of this genus from other regions of the world’s oceans.     

Phylogenetic Systematics of Peccaries (Tayassuidae: Artiodactyla) and a Classification of South American Tayassuids

Tayassuidae is a family of pig-like Artiodactyla restricted to the New World. Despite its rich fossil history, they have received less attention from a taxonomic and phylogenetic perspective when compared to the Old World pigs, Suidae. In this study, we performed a computer assisted phylogenetic analysis using morphological and molecular data including fossil and extant Tayassuidae, using parsimony and Bayesian approaches. We recovered the monophyly of the family Tayassuidae, confirming previous proposals, as well as the monophyly of the subfamilies Hesperhyinae and Tayassuinae, and the genus Platygonus, which we placed in a new taxon of tribe level. The three living peccaries and a number of fossil species belong to a new, tribe level, monophyletic group. The genus Catagonus comes out as paraphyletic, leading us to propose to restrict the generic name to the type species, C. metropolitanus, and a new taxonomic arrangement for the remaining species previously included in it, revalidating the genera Brasiliochoerus and Parachoerus, and describing a new genus, Protherohyus, gen. nov.     

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.     

Ichneumon flies of the genus <Emphasis Type="Italic">Trieces</Emphasis> (Hymenoptera,Ichneumonidae, Metopiinae) from Peru

Trieces peruanus sp. n. from Peru is described, Trieces riodinis Gauld et al. is recorded from this country for the first time. Trieces peruanus belongs to the T. dentatus species-group, it is similar to Trieces dentatus H. Townes et M. Townes, according to the degree of development of the prepectal keel and lateral keels of the scutum, as well as to the presence of hairs along the upper margin of the metapleura. The new species differs from T. dentatus in the entirely black metasoma, black hind leg with the yellow apex of the femur and base of the tibia, and darkened upper margin of the clypeus.     

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)

Ixodes goliath n. sp. (Acari: Ixodidae), is described based on females collected from the eastern hyomys, Hyomys goliath (Milne-Edwards) (Rodentia: Muridae) from Papua New Guinea. Females of I. goliath n. sp. are similar to those of I. priscicollaris Schulze, 1932 but can be distinguished by the overall size, porose areas sculpture and shape of palpal segment I ventrally. For comparative purposes, the female of I. priscicollaris is redescribed. Studied females of I. priscicollaris were found on murid rodents and Phascogale sp. (Dasyuromorphia: Dasyuridae) from Indonesia (Papua Province) and Papua New Guinea.     

A new species,a new synonym,and new records of the hover-fly genus <Emphasis Type="Italic">Cheilosia</Emphasis> Meigen (Diptera,Syrphidae)

A new species, Cheilosia richterae sp. n., is described in the nominotypical subgenus, being most closely related there to Ch. annulifemur Stackelberg, 1930. Two species, Ch. sootryeni Nielsen, 1970 and Ch. rufimana (Becker, 1984), are recorded from Russia for the first time. Ch. kuznetzovae Skufjin, 1977 is recorded for the first time from the Urals and western Siberia. The subgenus Nephocheila Barkalov, 2002 is synonymized with Nephomyia Matsumura, 1916. Figures of the male and female heads and the male genitalia are given for all the species.     

Caprinae (Bovidae,Artiodactyla, Mammalia) from the Neogene of Mongolia

Gobiocerus mongolicus Sokolov, 1952, Turcocerus kekemaidengensis Ye Jie et al., 1999; and Hypsodontus sp. were recorded in Miocene deposits of the Valley of Lakes (MN4-MN8) and Oioceros atropatenes (Rodler et Weithofer, 1890) occurred in the Mio-Pliocene (MN11-MN20) of northwestern Mongolia. Gobiocerus, Turcocerus, and Hypsodontus represent the same evolutionary lineage. Thus, Caprinae existed in Central Asia in the Early Miocene. They diverged from the Bovidae at the Oligocene-Miocene boundary. The presence of early bovids in this region suggests that this group could have appeared in Central Asia.     

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.     

Palaearctic species of the <Emphasis Type="Italic">Microchelonus retusus</Emphasis> group (Hymenoptera,Braconidae, Cheloninae)

Microchelonus species of the M. retusus group differ from the other members of the subgenus Microchelonus s. str. (characterized primarily by the 16-segmented female antennae and deepened apical abdominal opening of the male) in their elongate carapace of female abdomen more strongly narrowed apically than toward base. The first key to 45 species of this group, including 7 new species, is given: M. alexeevi Tobias, 1986 (apicalis Alexeev, 1971); M. angustiventris Tobias, 1986; M. apicalis Papp, 1971; M. arnoldii (Tobias, 1964); M. artus Tobias, 1986; M. cisapicalis Tobias, 1989; M. crassitarsus Tobias, 1989; M. dolosus Tobias, 1989; M. elenae Tobias, 1995; M. erosus Herrich-Schaeffer, 1838 (analipennis Fahringer, 1934; hungaricus Szépligeti, 1896; frivalaldszkyi Shenefelt, 1973); M. heraticus Tobias, 1985; M. hofferi Tobias et Lozan, 2006; M. jonaitisi Tobias, 2000; M. justus Tobias, 1989; M. kievorum sp. n.

Uncovered Diversity of a Predominantly Andean Butterfly Clade in the Brazilian Atlantic Forest: a Revision of the Genus <Emphasis Type="Italic">Praepedaliodes</Emphasis> Forster (Lepidoptera: Nymphalidae,Satyrinae, Satyrini)

The genus Praepedaliodes Forster, 1964, the only representative of the mega-diverse mostly Andean Pedaliodes complex lineage in the Brazilian Atlantic Forest, is revised. Prior to this study, four species were known, P. phanias (Hewitson, 1862), P. granulata (Butler, 1868), P. amussis (Thieme, 1905) and P. exul (Thieme, 1905). Here, a further six are described, all from SE Brazil, expanding to 10 the number of species in this genus. Lectotypes are designated for P. phanias, P. granulata and P. amussis. The genus is most diverse in the Serra da Mantiqueira (São Paulo, Rio de Janeiro, Minas Gerais) and in the Serra Geral (Paraná, Santa Catarina) with seven species occurring in both ranges. Praepedaliodes phanias is the most widespread species and the only one found in the western part of the Atlantic Forest; only this species and P. duartei Dias, Dolibaina & Pyrcz n. sp. occurring to near sea level. Other species, P. zaccae Dolibaina, Dias & Pyrcz n. sp., P. francinii Freitas & Pyrcz n. sp., P. sequeirae Pyrcz, Dias & Dolbaina n. sp., P. landryi Pyrcz & Freitas n. sp. and P. pawlaki Pyrcz & Boyer n. sp. are strictly montane and the highest species richness is reached at 1400–1800 m. One species, P. sequeirae n. sp., is a narrow endemic found only at timberline in the Agulhas Negras massif above 2300 m. Immature stages are described for two species, P. phanias and P. landryi n. sp. Molecular data (barcode region of cytochrome oxidase, subunit I) and adult morphology, including male and female genitalia, support the genus as monophyletic, belonging to a predominantly Andean clade of the Pedaliodes Butler, 1867 complex. Morphological evidences, in particular female genitalia comparative analysis, indicate the genera Physcopedaliodes Forster, 1964 and Panyapedaliodes Forster, 1964 as possibly the closest relatives to Praepedaliodes. Molecular data are inconclusive in this respect.     

From Eastern Arc Mountains to extreme sexual dimorphism: systematics of the enigmatic assassin bug genus <Emphasis Type="Italic">Xenocaucus</Emphasis> (Hemiptera: Reduviidae: Tribelocephalinae)

The Eastern Arc Mountains (EAM) have long been recognized as an area of extraordinary endemic biodiversity but have remained understudied compared to other biodiversity hotspots. The tribelocephaline assassin bug genus Xenocaucus China & Usinger, 1949, currently comprises two species known from the Uluguru Mountains of the EAM and Bioko Island in the Gulf of Guinea. Both species are based on single apterous and apparently eyeless female specimens. Based on collections resulting from extensive leaf litter sampling in Tanzania and Ethiopia, we here describe six new species, five based on females (Xenocaucus chomensis, n. sp., Xenocaucus kimbozensis, n. sp., Xenocaucus nguru, n. sp., Xenocaucus rubeho, n. sp., and Xenocaucus uluguru, n. sp.) and Xenocaucus ethiopiensis, n. sp., for which we discovered a macropterous male with well-developed eyes in addition to the apterous females. Molecular phylogenetic analyses indicate that Xenocaucus ethiopiensis, n. sp., is the sister taxon to the Tanzanian clade and support morphology-based species concepts. Divergence dating shows that diversification in the Tanzanian clade started ～15 mya, with the youngest species-level split occurring ～8 mya. Three species occur across multiple mountain ranges in the EAM or occur also on Mt. Hanang, and biogeographic analyses suggest a complex history of Xenocaucus in East Africa.     

New and little known orthopteroid insects (Polyneoptera) from fossil resins: Communication 3

New taxa of Orthoptera Ensifera are described in the families Mogoplistidae [Protomogoplistes asquamosus gen. et sp. nov. (Upper Cretaceous) in the subfamily Protomogoplistinae subfam. nov. and Archornebius balticus gen. et sp. nov. (Eocene), Pseudarachnocephalus gen. nov., P. dominicanus sp. nov., and P. latiusculus sp. nov. (all Miocene) in Mogoplistinae] and Gryllidae [Eopentacentrus borealis gen. et sp. nov. (Eocene), ?Grossoxipha feminea sp. nov. (Miocene), and Apentacentrus copalicus sp. nov. in the subfamily Pentacentrinae, ?Cyrtoxipha electrina sp. nov. and ?Cyrtoxipha illegibilis sp. nov. (both Miocene) in Trigonidiinae, and Baltonemobius fossilis gen. et sp. nov. (Eocene) in Nemobiinae]. The Miocene genera Proanaxipha Vickery et Poinar and Grossoxipha Vickery et Poinar are transferred from the subfamily Trigonidiinae to Pentacentrinae. P. latoca Vickery et Poinar and Abanaxipha longispina Vickery et Poinar are redescribed; the male of the latter species is described for the first time.     

Two new species of <Emphasis Type="Italic">Trouessartia</Emphasis> Canestrini, 1899 (Astigmata: Trouessartiidae) from passeriform birds in Brazil

Two new feather mite species of the genus Trouessartia Canestrini, 1899 (Analgoidea: Trouessartiidae) are described from passerines (Aves: Passeriformes) in Brazil: T. calcealgiana n. sp. from Philydor atricapillus (Wied) (Furnariidae), and T. gigaphallus n. sp. from Tyrannus melancholicus Vieillot (Tyrannidae). Both species have unique features, such as the large hook-like seta sR on trochanters III in T. calcealgiana, and the large male genitalia in T. gigaphallus, which are at least twice as long as normally found in most species of Trouessartia.
