― Pandiculation within spiders has only recently been discovered - the first record of this habit among Protostomia – and it has only been demonstrat-ed in one species ( Cyclosa argenteoalba ). We report here four further araneoid species i.e. Argiope bruennichi , Cyrtophora ikomosanensis , Trichonephila clavata (all Araneidae), and Nihonhimea japonica (Theridiidae) exhibiting pandiculation in or on their own webs. These records suggest that pandiculation is widely distributed at least among the superfamily Araneoidea, members of which generally construct aerial webs and wait in ambush for a long period.

raccoons feral raccoons Hap lochernes sp. other feral raccoons. Therefore, the use of feral raccoons as hosts by Haplochernes sp. for phoresy may not be obligated. However, this case demonstrates that arboreal pseudoscorpions are able to ride feral raccoons. By collecting more information on rac-coon-phoresing pseudoscorpions, the relationship of phoresy Abstract ― A pseudoscorpion was found in the un derfur of a feral raccoon ( Procyon lotor ) captured in western Tokyo in December 2019. Based on the morphological features, we identified the specimen as Haplochernes sp. This arboreal pseudoscorpion rides other arthropods and small mammals for dispersion, but little is known that the species rides medium-sized mammals such as raccoons. To our knowledge, this is the first case report of Haplochernes sp. riding a feral raccoon. Given that raccoons are an invasive species in Japan, further records of pseudoscorpions riding feral raccoons may elucidate the relationship between feral raccoons and pseudoscorpions.

― Low-molecular-weight carbohydrates accumulated in the overwintering adults of Parasteato da tepidariorum were identified. At least three compounds, sorbitol, scyllo -inositol, and myo -inositol, were detected in the extract. The spectrum and the amounts of accumulated polyols were almost the same as those accumulated in the overwintering nymphs. Thus, within the same species, winter polyol metabolism did not differ between the developmental stages.

This species is similar to O. stella Kamura 2005, but is distinguished from the latter by the male palpal bulb lacking an apophysis on the prolateral side and the longer spermathecae in the female genitalia.

― Robertus nipponicus Yoshida 1995 (Araneae: Theridiidae) was described using a male specimen collected from Kumamoto Prefecture, Japan, and additional specimens, including females, have never been obtained since the original description. In this paper, we described the female of R. nipponicus for the first time, using specimens collected from Kochi Prefecture, Japan. Females of this species can be distinguished from those of the congeners, R. sibricus Eskov 1987, R. ussuricus Eskov 1987, and R. mediterraneus Eskov 1987, by the narrow, transversely longer, and inverted v shaped copulatory openings. We also provided additional morphological information of the male.
