ジャーナル フリーIn this short paper, details about the observation of a juvenile mermithid roundworm parasitizing the crab spider Heriaeus spinipalpus are presented. The morphology of both organisms is briefly discussed. This is the first record of nematode parasitism in spiders of the genus Heriaeus.抄録全体を表示PDF形式でダウンロード (334K)

ジャーナル フリーHeptathela spiders of Okinawajima Is. were taxonomically revised using DNA sequence data. An analysis of mt-COI gene sequences revealed two clades (HY and HH), one of which (HY) was identified as Heptathela yanbaruensis because HY included specimens from Yona, the type locality of this species. To evaluate gene flow between HY and HH, the sequences of the nuclear 28S-rRNA and histone H3 genes were analyzed for specimens collected from two sympatric localities. In the two nuclear genes of HY and HH, all specimens had 5 homozygous positions with bases that differed between HY and HH. This indicates that there has been no gene flow between HY and HH, which is solid evidence for their reproductive isolation. Thus, it was concluded that HY and HH should be recognized as independent species, and HH is described as a new species under the name Heptathela helios n. sp. There were no good morphological diagnostic features other than the body size of the adult males of the two species (yanbaruensis ＜ helios); thus, females of these two species can be distinguished only by DNA sequence data.抄録全体を表示PDF形式でダウンロード (1204K) -

ジャーナル フリーA new species of the spider genus Actinopus Perty 1833 from Northwestern Argentina is described ― Actinopus goloboffi sp. nov. This is the second species described from the genus in the country. Detailed morphological descriptions of both sexes, illustrations and geographic distribution of the new species are presented.抄録全体を表示PDF形式でダウンロード (1044K) -

ジャーナル フリーJapanese salticid species of the genus Tasa and a part of the genus Pseudicius are taxonomically revised by morphological investigation and molecular analysis using partial sequencing data of mt-DNA COI gene. As a result, the female of Pseudicius koreanus Wesolowska 1981 and the male of Tasa nipponica Bohdanowicz & Prószynski 1987 are identified as the same species. Therefore, T. nipponica is newly synonymized with P. koreanus, and P. koreanus is transferred to the genus Tasa, due to its male genital morphology. The male of P. koreanus sensu Bohdanowicz & Prószynski (1987) is identified as the male of Pseudicius tokaraensis (Bohdanowicz & Prószynski 1987). Incidentally, P. okinawaensis Prószynski 1992 is newly synonymized with P. tokaraensis. Additionally, Pseudicius kimjoopili (Kim 1995) comb. nov. is newly recorded from Japan. The male of this species is described for the first time. This species is transferred from the genus Helicius. After these taxonomic revisions, Japanese Pseudicius species are following three for the present: P. kimjoopili, P. tokaraensis and P. vulpes. These three can be easily distinguished from each other by their general appearances or genital morphologies.抄録全体を表示PDF形式でダウンロード (1822K) -
