    National Institute of Biological Resources

    The spider genus Haplodrassus of Gnaphosidae in Korea comprises 5 species to date (Namkung et al., 2009); Haplodrassus kulczynskii Lohmander, 1942, Haplodrassus montanus Paik and Sohn, 1984, Haplodrassus pargongsanensis Paik, 1992, Haplodrassus signifer (C. L. Koch, 1839), and Haplodrassus taepaikensis Paik, 1992. One male of H. mayumiae was collected during the intensive survey of spider fauna of agricultural landscape by using pitfall trap. This species is formerly only known to be found in Japan. The spider genus Mangora of Araneidae in Korea comprises only one species, Mangora herbeoides (Bösenberg and Strand, 1906). This species is formerly only known to be found in China. One female of M. crescopicta was collected in mountainous region by using sweep net. In the present paper, H. mayumiae and M. crescopicta were described with illustrations of taxonomic characters.

    Materials and Methods

    The external morphology of H. mayumiae and M. crescopicta were examined and the taxonomic characters of each species were illustrated using a stereoscopic dissecting microscope (Olympus SZ60). Measurements were made with an ocular micrometer and are recorded in millimeters. Leg measurements are given as “leg number, total length (femur, patella+tibia, metatarsus, and tarsus).” Pedipalp measurements are listed as “total length (femur, patella + tibia, and tarsus).” The following abbreviations are used in the description: AME, anterior median eye; ALE, anterior lateral eye; PME, posterior median eye; PLE, posterior lateral eye; AER, anterior eye row; PER, posterior eye row; d, dorsal surface, p, prolateral surface, r, retrolateral surface and v, ventral surface in leg spiniformation. Specimens examined in this study are lodged in the collection of National Institute of Biological Resources (NIBR), Korea.
