New records of the mygalomorph spiders from Nara Prefecture

Mikio Sekine

Several localities of the Mygalomorphs or trapdoor spiders and their kin, i.e. Latouchia

typica (Ctenizidae), Conothele fragaria (Ctenizidae) and Calommata signata (Calommatidae), are newly recorded from Nara Prefecture (Figs. 1–3). Each species is listed as the near threatened species. I am grateful to Mr. Koshi Shimohara (Nara Kinoko-no-kai) for giving information regarding the spider pathogenic fungi Nomuraea atypicola.

Does the orb web spider Argiope boesenbergi live in mountainous regions by choice?

Mikio Sekine

It has been pointed out that the orb web spider Argiope boesenbergi lives in mountainous

regions by choice, in comparison with Argiope amoena. In order to find out whether or not it is true, the distribution of A. boesenbergi and A. amoena was surveyed in Nara Prefecture in 2013–2014, respectively. I also checked out the observations on the spiders in other several prefectures. Figure 1 is a diagram showing the vertical distribution of A. boesenbergi and A. amoena. No significant differences existed between A. boesenbergi and A. amoena in distribution (Welch’s t test; P = 0.065). It suggests that the hypothesis is not quite right.
