Abstract Geolycosa vultuosa (C. L. Koch, 1838) (Lycosidae) is a large, deeply burrowing spider, occurring from south-eastern Europe to Central Asia. This species is found in a mountain pasture on Dajti Mountain in the Tirana district. The structure of the burrow and burrowing ecology of G. vultuosa are discussed in comparison to those seen in other species of wolf spiders. Four burrows of Geolycosa vultuosa inhabited by subadult and adult females were observed in soil vegetated with low grass and a few other low plants at the end of September 2014. These burrows were cast with cement and excavated. The burrows consisted of vertical to subvertical, slightly curved, or nearly straight shafts. Compared to other burrows of wolf spiders, three burrows of G. vultuosa did not show any basal chamber, but a gradual widening from the middle to the base. One burrow showed a basal chamber with a basal protrusion thinner than the shaft. Burrow surfaces and entrances were unornamented.
Geolycosa vultuosa (C. L. Koch, 1838)是一种大型深穴居蜘蛛,分布于欧洲东南部至中亚地区。这个物种是在地拉那地区Dajti山的一个山地牧场上发现的。讨论了秃鹫狼蛛的穴居结构和穴居生态,并与其他种类的狼蛛进行了比较。2014年9月底,在低矮草丛和少量低矮植物覆盖的土壤中,观察到秃头土蓼亚成虫和成虫各4个穴居。这些洞穴是用水泥浇筑的,然后挖掘出来的。这些洞穴由垂直到次垂直、略微弯曲或近乎笔直的竖井组成。与其他狼蛛的洞穴相比,兀狼蛛的三个洞穴没有基底室,而是从中间到底部逐渐变宽。其中一个洞穴显示出一个基底腔,其基底突起比轴还细。洞穴的表面和入口都没有装饰。

A suite of behavioural and morphological traits camouflage Allocyclosa bifurca (McCook, 1887) (Araneae: Araneidae) Allocyclosa bifurca (McCook, 1887) (Araneae: Araneidae) 的一系列行为和形态特征的伪装
Q3 Agricultural and Biological Sciences Pub Date : 2023-07-10 DOI: 10.13156/arac.2023.19.5.809
Abstract Several traits of adult female Allocyclosa bifurca, including the forms and the colours of the dorsal and the ventral sides of the abdomen that match bumpy and smooth surfaces and associated colours of the two sides of the egg sac, the colours and positions of the spider's legs and the spiders' prey wrapping behaviour and their orientation of prey packages while they feed all increase the match with the overall shapes and colours of the egg sacs, visually camouflaging the spider at the hub of its orb. This camouflage is partially broken in two contexts: apparent attempts to avoid overheating in direct sunlight, and feeding. Neither a predatory bird nor a parasitoid wasp showed signs of being fooled by the camouflage.
摘要 Allocyclosa bifurca 成年雌蛛的几个特征,包括腹部背侧和腹侧的形状和颜色与卵囊两侧凹凸不平和光滑的表面及相关颜色相匹配、蜘蛛腿的颜色和位置、蜘蛛的猎物包裹行为以及它们进食时猎物包裹的方向,都增加了与卵囊整体形状和颜色的匹配度,从而在视觉上伪装了蜘蛛的球体中心。这种伪装在两种情况下被部分打破:一是为了避免在阳光直射下过热,二是为了进食。捕食性鸟类和寄生蜂都没有被伪装迷惑的迹象。

Abstract Neriene clivosa sp. n. is described, based on a single male from northern Vietnam. The new species is characterized by a unique shape of the male carapace furnished with six conical projections at its edges. Based on the palp structure, N. clivosa sp. n. seems to be especially similar to N. longipedella (Bösenberg & Strand, 1906) and N. marginella (Oi, 1960), both southeastern Palaearctic, as well as to the Oriental N. strandia (Blauvelt, 1936). The new species can easily be distinguished from all known congeners by the shape of the carapace, in addition from the most similar species by some details of palpal structure.
摘要:本文描述了越南北部一种单雄海绵虫。这个新物种的特点是雄性甲壳的独特形状,边缘有六个锥形突起。根据触掌结构,N. clivosa sp. N.似乎与N. longipedella (Bösenberg & Strand, 1906)和N. marginella (Oi, 1960)特别相似,它们都是古北大陆东南部的N. strandia,以及东方的N. strandia (Blauvelt, 1936)。这个新物种可以很容易地从甲壳的形状上与所有已知的同类区分开来,此外还可以从触肢结构的一些细节上与最相似的物种区分开来。

Abstract The lycosid fauna of Saint Helena, consisting of entirely endemic species, is revised. Lycosa ringens Tongiorgi, 1977 and Lycosa elysae Tongiorgi, 1977 are redescribed and transferred to Antembolus gen. nov., creating the new combinations Antembolus elysae comb. nov. and Antembolus ringens comb. nov. Dolocosa dolosa O. Pickard-Cambridge, 1873, Hogna cinica Tongiorgi, 1977, H. inexorabilis (O. Pickard-Cambridge, 1870), H. ligata (O. Pickard-Cambridge, 1870), and H. nefasta Tongiorgi, 1977 are re-diagnosed and illustrated. Hogna sanctaehelenae (Strand, 1909) is confirmed to be a junior synonym of H. ligata, based on examination of photographs of the immature holotype. A remarkable new monotypic lycosine genus, Molearachne gen. nov., with a new species M. sanctaehelenae sp. nov., is described based on both sexes from Prosperous Bay Plain, where it makes unique mounds which have earnt it the local common name Mole Spider. Two further new endemic species are described: Dolocosa joshuai sp. nov., based on the female, and Hogna veseyensis sp. nov., based on both sexes. Thus, the fauna consists of four genera, including three endemic, and nine species, which are all endemic.

Pickard-Cambridge, 1870)和H. nefasta Tongiorgi, 1977重新诊断和说明。根据对未成熟的全模照片的检查,证实Hogna sanctaehelenae (Strand, 1909)是H. ligata的初级同义词。在繁盛湾平原描述了一个引人注目的单型lycos属Molearachne gen. nov.和一个新种M. sanctaehelenae sp. nov.,这是基于两性的,在那里它形成了独特的土丘,为它赢得了当地的俗称鼹鼠蜘蛛。另外还描述了两个新的特有种:基于雌性的Dolocosa joshuai sp. nov和基于两性的Hogna veseyensis sp. nov。因此,动物群由4属组成,其中3属为特有种,9种均为特有种。

Abstract Two new species of the genus Chapoda Peckham & Peckham, 1896 are described and illustrated from southern Ecuador. Both new species C. guancavilca n. sp. (♂♀) and C. santay n. sp. (♀) are described and illustrated from Puná and Santay Islands, Guayas province. In addition, two new genera records are reported from Ecuador: Bellota Peckham & Peckham, 1892 (with B. formicina (Taczanowski, 1878)) and Martella Peckham & Peckham, 1892 (with M. gandu Galiano, 1996), along with a new species record of Lyssomanes elegans (F. O. Pickard-Cambridge, 1900). Finally, new faunistic records are given for Corythalia scutellaris (Bayer, 2020), Frigga crocuta (Taczanowski, 1878), F. opulenta (Galiano, 1979), and L. unicolor (Taczanowski, 1871). A distribution map with these and previously published records on the genera here analysed is provided.

Abstract Cymbiapophysa Gabriel & Sherwood, 2020 is a theraphosine genus endemic to South America, diagnosable on genital organ morphology in both sexes, and the presence of a distal-retrolateral apophysis on the male cymbium. Examination of historical material in the Natural History Museum, London, recently revealed a new species from Carondelet, Ecuador, with distinct palpal bulb and tibial apophysis morphology, described herein as Cymbiapophysa seldeni sp. nov.

Abstract A new species of the ant-resembling jumping spider tribe Simonellini, Flurica amazonica sp. nov., is described from the Southwest Amazon forest in Beni Department, Bolivia. The species can be separated from its only congener Flurica sikimira Perger & Rubio, 2022 by the male palp lacking a dorsal tibial apophysis, the ventral tibial apophysis shorter, the embolus arising at the proximo-retrolateral side of the tegulum, and the chelicerae with three promarginal teeth. Adults of both Flurica species are likely mimics of the turtle ant Cephalotes pusillus (Klug, 1824).
摘要描述了玻利维亚贝尼省亚马孙西南部亚马孙森林中一种似蚁跳蛛族Simonellini, Flurica amazonica sp. nov.的新种。该物种可以与其唯一的同系物Flurica sikimira Perger & Rubio, 2022区分开来,因为雄性触须缺乏胫骨背突,胫骨腹侧突较短,栓子产生于胫瓣的近后外侧,并且有三颗前边缘牙齿。这两个Flurica物种的成虫很可能是龟蚁Cephalotes pusillus的模仿者(Klug, 1824)。

Abstract The female of Hersilia moheliensis Foord & Dippenaar- Schoemann, 2006 is described for the first time. The species is newly recorded from Madagascar, having previously been known from only a single specimen from the Comoros. Additionally, we provide new records of Hersilia insulana Strand, 1907 in Madagascar.
