A new synonymy of <I>Coelotes oshimaensis</I> Shimojana 2000 (Araneae: Agelenidae: Coelotinae) in Japan

Abstract

A new synonymy of coelotine spider is proposed through a comparison of the morphological characteristics and the results of our molecular analysis. Coelotes hachijoensis Ono 2008,described on the basis of specimens from Hachijo Island, is a junior synonym of Coelotes oshimaensis Shimojana 2000. The original distribution of C. oshimaensis is considered to be on Amami-oshima Island and the Tokara Islands in southwestern Japan, far from Hachijo Island. Various circumstantial evidences suggested that C. oshimaensis on Hachijo Island may have been artificially introduced from Amami-oshima Island.

Discovery of presumably introduced spiders, Oedignatha scrobiculata Thorell, 1881 (Araneae, Liocranidae) and Boagrius qiong Lin &amp; Li, 2022 (Araneae, Palpimanidae) on Chichi-jima Island, the Ogasawara Islands, Japan

“…A similar situation was observed on Hachijo-jima Island in the Izu Islands, Tokyo, Japan. On this Island, a funnel web spider, Coelotes oshimensis ( Araneae , Agelenidae ), originally from Amami-oshima Island in the Nansei Islands, co-existed sympatrically with a large number of invasive arthropods, such as Opisthoplatia orientalis ( Blattaria , Blattodae) and Chamberlinius hualienensis ( Diplopoda , Polydesmida , Paradoxosomatidae ) ( Okumura and Cheng 2023 ).…”
