A new spider species, Pardosa temreshevi sp. n., collected among screes on elevation over 3600 m, is described from southern Kazakhstan based on females. The new species has increased number of ventral spines on tibiae I. Pardosa temreshevi sp. n. is distantly similar to P. zhangi Song & Haupt 1995 from the highlands of Xinjiang Province (China) and distinctly differs from it by conformation of the epigyne.
A new pill millipede species, Hyleoglomeris magy sp. nov., is described from Okinawa and adjacent islands, Ryukyu Archipelago, Japan. The new species is mainly characterized by its large body (maximum length: 12.1mm) and general light yellowish-brown coloration marked with pairs of blackish spots. The general appearance of the new species resembles that of Hyleoglomeris hongkhraiensis Golovatch & Panha 2015, but can be distinguished from this species by the number of striae on the thoracic shield (typically 8–10, with 3 or 4 crossing the dorsum, vs 7 or 8 in total with 4 or 5 crossing the dorsum) and the shape of the telopod (femur strongly bulged distally, vs not bulged). An identification key to all five species of Hyleoglomeris known to occur in the Ryukyu Archipelago is also provided.
The types of four Oxyopes species kept in the British Musuem (Natural History), London and the National Zoological collection, Zoological Survey of India (Kolkata) are reexamined. Three new synonyms are recognized: Oxyopes nilgiricus Sherriffs 1955 syn. nov., O. pankaji Gajbe & Gajbe 2000 syn. nov. and O. ratnae Tikader 1970 syn. nov. with O. hindostanicus Pocock 1901. The updated distribution of O. hindostanicus is mapped with records from several new localities from India and Sri Lanka.
A new species from the spider genus Philoponella Mello-Leitão 1917 – Philoponella rostralis n. sp. (♂♀) is diagnosed and described from the Kottapara Hills, Western Ghats, Kerala, India. A detailed description of its morphology, diagnostic features, photographs and the depictions of the copulatory organs of both sexes are given.
Spiders of the genus Cybaeus are diverse in Japan and exhibit extensive morphological variation of their genitalia among species. Among Japanese Cybaeus, several species possess an elongated embolus in males and elongated spermathecae in females. Here, we describe Cybaeus iharai sp. nov. from Nagano Prefecture, central Honshu, Japan, which possesses a short embolus in males and short copulatory ducts in females. In addition, DNA sequences of the new species were obtained for future phylogenetic analyses.
Three new species of Pseudopoda, P. tatsumii n. sp. (♂♀), P. kenmun n. sp. (♂♀), and P. tokunoshimana n. sp. (♂♀), are described from Amami-oshima Is. and Tokunoshima Is., Japan, and a synopsis of Japanese species of the genus is provided. Four of the Japanese species cannot be distinguished based solely on general appearance, although can be separated by male palpal morphology, particularly the embolus. The epigynes are somewhat variable and insufficiently distinct to enable reliable species discrimination. The three species on Amami-oshima Island are parapatric, with unexpectedly narrow distribution ranges.
Araneus mayumiae (Araneae: Araneidae) is newly recorded as a prey of Eopompilus internalis (Hymenoptera: Pompilidae). In the laboratory, the spider was alive in approximately two months after being stung by the wasp.
Sphecotypus taprobanicus Simon 1897 is redescribed on the basis of the holotype female. Although the specimen is at a subadult stage, the shape of the carapace distinguishes S. taprobanicus from other Asian Sphecotypus species.
The species Masirana glabra (Komatsu 1957) is redescribed based on fresh specimens collected in the type locality, 65 years after its original description. The female is recorded and described for the first time. Habitus and genitalia of both sexes are illustrated in detail and the DNA barcode of the species is provided. Additional notes on the ecology of the species are reported. Our morphological and ecological observations further support M. glabra as a true troglobiont.
This paper describes field-based observations of male-male agonistic behavior in a longlegged sac spider Cheiracanthium eutittha (Araneae: Cheiracanthidae). Males of the species exhibited a characteristic agonistic behavior, where two males hung from leaves with a dragline, with all of their long legs entangled with each other and pushed each other’s body aggressively. To the best of my knowledge, this is the first video-based report of male-male agonistic behavior associated with usage of elongated legs in this spider family.
