The fine structure of the hemocytes in Wolf spider, Pardosa astrigera, is discribed and compared with that of similar cells in other spider species and insects. Five hemocyte types are identified in the hemolymph: prohemocyte, plasmatocyte, granulocyte, spherulocyte and adipohemocyte. Prohemocytes are small with a relatively undifferentiated cytoplasm. The nucleus is comparatively large and has a perinuclear space. Plasmatocytes and granulocytes are pinocytotic function in the hemolymph of the body. The plasmatocytes have some coated pits on the plasma membrane and well developed Golgi complex, The granulocytes appear sequence of events in the formation of coated vesicle from a coated pit on its plasma membrane. Golgi complex become well expressed and give rise to small secretory vesicles which fuse to large bodies. The spherulocytes are larger in cell size than other hemocytes. Their cytoplasm is filled with spherules. The spherules contain the floccurent materials and the helical structured materials, which are 220nm in length and 80nm in width. The adipohemocytes are oval shaped and have a number of lipid droplets.

Though the wandering spiders do not produce webs for prey-catching, they have silk producing apparatus. Among the four kinds of silk glands in the wolf spider, Pardosa astrigera, the ampullate one is the most predominant gland in both sexes, and is composed of three functional parts; excretory duct, storage ampulla and convoluted tail regions. The duct is basically composed of three superposed types of layers which are inner cuticles, monolayered epithelial cells and peripheral connective cells. The electron lucent subcuticles which have the functions of water removal and orientation of silk fibers during polymerization are well developed at the anterior region near the spinneret. Whereas the endocuticles which contain two types of banding patterns at the cross section are developed at the rest of the duct region. The secretory silks are synthesized within the glandular epithelial cells of the tail as secretory granules, and then released to the inner cavity of the storage ampulla by the mechanism of apocrine secretion. Most of these secretory vesicles are originated from the rough endoplasmic reticula of the glandular epithelial cells, whereas no Golgi complexes are found in any of the cells which have been examined.

The book lung in the wolf spider, Pardosa astrigera was consisted of a series of flattened triangular-shaped air sacs, stacked with about 70 sheets, and was located in the ventrolateral region of opisthosoma. Each hemolymph spaces (average $8{\mu}m$ in thickness) surrounded by the air sacs (average $6{\mu}m$ in thickness). The air sacs was supported by cylindrical cuticular spikes of microfibril bundles. Epithelial cell processes surrounded the hemolymph spaces. The nuclei of the epithelial cells were concentrated near the atrium. In the middle portion of air sac, the epithelial cells formed pillars across the hemolymph spaces and spot desmosome and zonula adherens were seen between the plasma membranes. In the hemolymph space of this spider, granular hemocytes (average diameter $8{\mu}m$) were the most dominant type of hemocytes. In the medial sinus, the hemolymph flow between the air sacs of a paired book lungs and then flow out of the lung vein. The air comes in the atrium through the ventral lung slit and makes a tidal wave in and out of the air sacs.

Three wolf spiders of the family Lycosidae Sundevall, 1833 are newly described from Korea: Arctosa labiata Tso & Chen, 2004, Pardosa altitudis Tikader & Malhotra, 1980, and Pardosa laevitarsis Tanaka & Suwa, 1986. These spiders were collected during a seasonal survey of the spider fauna of National Parks located in Gangwon-do and Gyeongsanbuk-do in 2018-2019; two males of A. labiata from Mt. Songnisan National Park, one female of P. altitudis from Mt. Chiaksan National Park, and two males of P. laevitarsis from Mt. Odaesan and Sobaeksan National Parks. The three newly recorded spiders have previously been known to be distributed in Taiwan, India, China, and Japan. These spiders were collected by hand in mixed forest leaf litter in mountainous terrains. The present paper taxonomically describes these three wolf spiders with measurements and morphological illustrations.

The morphological and histologic differentiation of the central nervous system (CNS) in the wolf spider Arctosa kwangreungensis with respect to postembryonic development are studied using light and scanning electron microscopes. The organization of CNS which consisted of supraesophageal ganglion (SpG) and subesophageal ganglion (SbG) are established prior to the postembryo stage. The brain of first instar spiderling after a molt of the postembryo is also made up of supraesophageal ganglion and subesophageal ganglion. Although development of the optic nerve and optic lobe in SpG are not completed during the postembryoic stage, completion of whole neural system resemble to that of adult are established during the second instar stage. In particular, optic gangalion is developed from the undifferentiated cell clusters of the SpG, moreover four pairs of appendage ganglia and another pairs of abdominal ganglia are produced from the SbG. Nerve cells of the most developing stages are composed of typical monopolar neur1ons, and total three types of neurons can be identified through the histological and morphological basis of present study. These cell clusters are differentiated into neurons and grow dendritic fibers according to further development of the CNS.
