  • 풀거미속( Agelena ) 의거미는 1805년에 Walckenaer 에 의하여 창설된이후 오늘에 이르기까지 약 70종이 기재되었으며 동양에서는 13종이 보고되었는데 그 대부분이 일본 (6종)과 중국(4종)산다. 한국산 풀거미속은 Kamble, T.(1932), Kishida, K(1933) 및 저자(1962)등에 의하여 Agelena labrinthica ,A.kimbata, A.opuleta 의 3 종이 보고되었다. 금 반 저자 소장의 표본을 정리 분류한 결과 1미기록종과 3 신종을 얻었기에 이에 기재하였다. 즉, 미기록종 Agelena difficuilis Fox, 1936. 신종 Agelena choi, a.koreana, A.jirisanensis ※ Agelena choi 의 종명은 조복성박사에게 봉헌한 것이다.

  • 깔때기거미屬(Coras)은 1898年에 E. Simon이 創設한 이래, 北美洲에서 約 15種, 極東地域에서 다음 3種이 記載되었다. 卽 C. insidiosus(L. Koch, 1877) 日本 C. luctuosus(L. Koch, 1877) 日本 $\\cdot$ 中國(\ulcorner) C.plancyi(Simon, 1880) 日本 $\\cdot$ 中國 本屬은 Coelotes 屬과 매우 닮아서, 그 사이에 뚜렷한 區分을 지우기란 困難하며, 따라서 種의 所屬에도 적지않은 混亂을 招來하고 있다. 本屬은 종래에는 Ageleidae의 Ageleninae에 所屬시켜 왔으나 最近에 Lehtinen(1967)은 이것을 F.O. Pickard-Cambridge(1893)가 設定한 Coelotinae로 옮겼는데 이것은 매우 타당한 處事라 하겠다. 韓國産 Coras 屬에 對해서는 白(1942, 1962, 1967), 白 $\\cdot$ 金(1956) 및 南宮(1964) 等이 日本과 共通種인 Coras insidiosus를 報告한바 있다. 그러나 이번 調査에서 이것은 Coelotes songminjae Paik et Yaginuma, 1969의 synonym으로 밝혀졌으므로 우리 나라의 spider fauna에서 除外하기로 했다. 한편 筆者 所藏의 標本을 整理한 結果 새로히 1韓國未記錄種 과 1新種을 얻었기에 이에 記載하는 바이다. 韓國未記錄種 Coras luctuosus (L.

  • Four new species of the genus Alloclubionoides collected from mountain litter and hillock litter around the agricultural ecosystem of Korea are described in the present work with appropriate body measurements and morphological illustrations; A. hwaseongensis sp. nov., A. imi sp. nov., A. namhansanensis sp. nov. and A. nasuta sp. nov. Females of A. hwaseongensis sp. nov., A. namhansanensis sp. nov. and A. nasuta sp. nov. can be distinguished based on the epigyne shape and structure of internal genitalia from previously described species. Males of A. imi sp. nov. can also be distinguished based on the shapes of retrolateral tibial apophysis, embolus tip and conductor from previously described species. Also, a key to the Korean Alloclubionoides spiders is provided. Alloclubionoides gajiensis Seo, 2014 is newly synonymized with Alloclubionoides cochlea (Kim et al. 2007).

  • Among the four kinds of silk glands in the funnel-web spider Agelena limbata, the ampullate gland for dragline silk production is the most predominate one in both sexes, and is composed of three functional parts-excretory duct, storage ampulla and convoluted tail regions. Two pairs of major ampullate glands send secretory ductules to the anterior spinnerets, and another two pairs of minor ampullate glands supply the middle spinnerets. There are no apparent differences between the major and minor ampullate glands not only the external spigots but also their internal silk glands. However, the microstructure is very unique in this spider, because each gland has spherical shaped storage sac with twig-like branched tails. Nevertheless, the wall of the secretory region is similarly composed of a single layer of epithelial cells. The mature secretory silks in glandular epithelium are closely packed and accumulated as electron-opaque vesicles. Most of the secretory products which originated from the rough endoplasmic reticula(rER) are grown up by fusion with the surrounding small vesicles however, the Golgi complex does not seem to play an important role in this process of secretion.
