Abstract

Four species of the families Gnaphosidae and Clubionidae are reported. Cladothela unmunensis n. sp. is described from Gyeongsangbuk-do, Korea. Drassodes longispinus Marusik and Logunov, 1995, Gnaphosa inconspecta Simon, 1878 and Clubiona tongdaoensis Zhang, Yin, Bao and Kim, 1997 are newly recorded to the Korean spider fauna.

    INTRODUCTION

    The genus Clubiona is the largest group in the spider family Clubionidae, including 494 species worldwide (World Spider Catalog 2017). Of these 28 species are known from Korea (Yoo et al. 2015). The spider family Gnaphosidae includes 2197 species in 125 genera, distributed worldwide. Among them, genera Cladothela, Drassodes and Gnaphosa comprise 10, 168 and 145 species respectively, and in Korea, 4, 3 and 8 species respectively (World Spider Catalog 2017; Yoo et al. 2015).

    While studying specimens collected during the Korean indigenous species survey, four species were identified as a new species and three species new to Korea; Cladothela unmunensis n. sp., Drassodes longispinusMarusik and Logunov, 1995, Gnaphosa inconspectaSimon, 1878 and Clubiona tongdaoensisZhang, Yin, Bao and Kim, 1997.

    MATERIALS AND METHODS

    The sequence of leg segments in measurement data is as follows: total (femur, patella, tibia, metatarsus, tarsus). The abbreviations used in the text: c, carapace length; d, p, r and v in leg spination are dorsal, prolateral, retrolateral and ventral side of leg, respectively; Leg I, length of leg I; AER, anterior eye row; ALE, anterior lateral eye; ALE-PLE, distance between ALE and PLE; AME, anterior median eye; AME-ALE, distance between AME and ALE; AME-AME, distance between AMEs; AME-PME, distance between AME and PME; PER, posterior eye row; PLE, posterior lateral eye; PME, posterior median eye; PME-PLE, distance between PME and PLE; PME-PME, distance between PMEs. All measurements in the text are given in millimeters. The type specimens are deposited in the National Institute of Biological Resources (NIBR), Ministry of Environment, Korea.
