First records of the arboreal wolf spider species Hogna trunca Yin, Bao & Zhang 1996 (Araneae: Lycosidae) from Japan

[摘要] The arboreal lycosid species, Hogna trunca Yin, Bao & Zhang 1996, is newly recorded fromJapan. Hogna trunca was originally described from Zhejiang Province (China) and has been known only fromChina. The author confirmed its presence in Nara Prefecture and in the northern part of the Okinawa Island inJapan, reporting it as a new record for the country. The genus Hogna is also new to Japan. In both areas, thespecies was found in forests along streams and was observed waiting on tree bark or hiding in tree hollowsmainly at night. Presumably, the species has not been discovered until recently because of its unique arborealecology for a spider of the family Lycosidae, which mainly includes ground-dwelling species.
