A survey of Pireneitega from Tajikistan (Agelenidae, Coelotinae)

Five new species of Pireneitega species from Tajikistan are described: P. zonsteini sp. n. (male female), P. muratovi sp. n. (female), P. tyurai sp. n. (female), P. ramitensis sp. n. (female) and P. kovblyuki sp. n. (male). Pireneitega major (Kroneberg, 1875) is redescribed for the first time based on the lectotype designated here. DNA barcodes for the five new species are documented for future use and as proof of molecular differences between these species

Who is Eresus tristis Kroneberg, 1875 (Aranei: Eresidae)?

The male palp of the holotype of Eresus tristis Kroneberg, 1875, a species considered a junior synonym of E. kollari Rossi, 1846, is illustrated. A comparison with the palp of E. kollari reveals clear differences, and therefore E. tristis is revalidated. The previously unknown type locality is recognized as southernmost Kazakhstan. All literature records of E. tristis are surveyed, and it seems that records from Eastern Kazakhstan and Xinjiang (China) refer to an undescribed species

A new Gongylidioides Oi, 1960 from Taiwan (Aranei: Linyphiidae)

A new species, Gongylidioides protegulus sp.n., is described from Chiayi and Pingtung counties of Taiwan. The new species differs from the known congeners by the structure of the copulatory organs, mainly by the long, thin, looped embolus and conically protruded, membraneous protegulum, as well as by the shape of the epigynal ventral plate

Redescription of two poorly known Arctic Hilaira species (Aranei: Linyphiidae) with notes on species grouping

Two poorly known Hilaira species, H. incondita (L. Koch, 1879) and H. proletaria (L. Koch, 1879) are redescribed and their copulatory organs are illustrated in detail by means of digital and SEM photographs. Maps of the known records of two species are provided as well. Species grouping in the genus are briefly discussed

Descriptions of the two-eyed African spider genera Chedimanops gen. n. and Hybosidella gen. n. (Araneae, Palpimanidae, Chediminae)

Two new genera of chedimine palpimanids are described. Chedimanops gen. n. includes the type species, C. eskovi sp. n. (male female), and C. rwenzorensis sp. n. (male female), both from the far eastern part of the Democratic Republic of Congo (Rwenzori Mts.). The monotypic Hybosidella gen. n. is based on H. etinde sp. n. (male) from Cameroon. The new genera differ from all other Palpimanidae by possessing only the anterior median eyes (all other eyes are lost). These new genera can be distinguished from one another by the shape of the thoracic fovea (a narrow bracket-shaped pit vs. a longitudinal groove, respectively), as well as by the structure of the abdominal scuta and the male copulatory organ, peculiarities of coloration, amongst other characters. The taxonomic position and relationships of the newly described taxa are briefly discussed. The distinctive characters and a key to both species of Chedimanops gen. n. are also provided

New species and records of Filistatidae (Arachnida: Aranei) from Iran

Three new species of Filistatidae are described from Iran: Microfilistata magalhaesi sp.n. (male, Isfahan Province, central Iran), Zaitunia darreshurii sp.n. (female, Lorestan Province, southwestern Iran) and Z zagrosica sp.n. (female, Kohgiluyeh & Boyer-Alunad Province, southwestern Iran). Microfilistata Zonstein, 1990 is recorded from Iran for the first time, and its record lies at the southwesternmost limits of the generic range. Hitherto, the genus included two species described from Uzbekistan and Turkmenistan. New records are provided for Filistata lehtineni Marusik et Zonstein, 2014 and Zaitunia akhanii Marusik et Zamani, 2015, representing the southernmost localities of the species ranges. Collecting localities of Microfilistata and all the Filistatidae occurring in Iran are mapped

On the northernmost record of Pritha (Aranei: Filistatidae) in the Caucasus and entire Asia with notes on Filistatidae from Caucasus

Pritha pallida Kulczynski, 1897, a species previously known from Madeira to Western Greece, has been found in Georgia. This species is illustrated, and its distribution is commented and mapped. The distribution and taxonomic status of all Filistatidae species known from the Caucasus are briefly discussed

A survey of East Palaearctic Gnaphosidae (Aranei). 9. New data on the Parasyrisca potanini-group from Central Asia

Both sexes of three new species of Parasyriscaare described from Eastern Kazakhstan and Western Mongolia: P. kosachevi sp.n., P. sulaki sp.n., and P. tronovorum sp.n. All new species were collected in highlands at elevations from 2700 to 3700 m. The female of P. volynkini Fomichev, 2016 from the Altai Mountains (South Siberia, Russia) is described for the first time. Descriptions, differential diagnoses, illustrations, and maps of distribution records are provided. The distribution and species composition of the all four Parasyrisca groups (potanini, vinosa, guzeripli, and breviceps) are discussed

On the synonymy of two Acantholycosa species (Araneae, Lycosidae) from the Altai

Two species previously known from East Kazakhstan, Acantholycosa katunensis Marusik, Azarkina & Koponen, 2004, known from the holotype male, and A. kurchumensis Marusik, Azarkina & Koponen, 2004, syn. n. known from females, are synonymized, and priority is given to A. katunensis. Acantholycosa katunensis is reported for the first time in the Russian Altai. Both sexes of this species are illustrated, and a distribution map is provided.</p

New data on Hahnia CL Koch, 1841 from Crimea (Aranei: Hahniidae)

Four species of Hahnia are recorded from Crimea: H. helveola Simon, 1875; H. nava (Blackwall, 1841); H. ononidum Simon, 1875; and H. pusilla C. L. Koch, 1841. Two species, namely H. ononidum and H. pusilla, are recorded from Crimea for the first time. Crimea is the easternmost point of the known range for H. helveola. Illustrations, diagnoses, distribution data, habitats, and seasonal dynamics of activity are presented
