JOURNAL FREE ACCESSThree new species of the subfamily Coelotinae are described from Kyushu, Japan, under the names, Coelotes gotoensis n. sp., Coelotes iharai n. sp. and Iwogumoa nagasakiensis n. sp. Coelotes gotoensis is a large and dark-colored coelotine spider, which has two retromarginal teeth on chelicera, and is characterized by having large and digitiform patellar apophysis on male palp. This new species has only been found in Narushima Is., Goto Islands, Nagasaki Pref. Coelotes iharai is characterized by having palpal conductor roundish in male and epigynal teeth sharp by pointed in female. This new species lives in Mts. Kirishima and the surrounding areas between Miyazaki and Kagoshima Pref. and the entire region of Kumamoto Pref. Iwogumoa nagasakiensis has a characteristic spatula-shaped conductor in male palp.

JOURNAL FREE ACCESSThe breeding season and the factors affecting fertility of Japanese foliage spider, Cheiracanthium lascivum, were investigated in Kanazawa City of central Japan. In grasslands of three study sites, Asano, Tawara, and Katano, the nests made of leaves of perennial grasses were collected from late May to July. A total of 167 nests were collected, and 83 of them (49.7%) included a single adult female with an egg sac or spiderlings. The females attended their offsprings within the nests, but matriphagy, which is known in a congeneric species, C. japonicum, was not found. Average number of offsprings (eggs or spiderlings) per nest was 143.6±5.5 (SE). It was significantly different among the study sites, and the largest number was produced in Katano. The multiple regression analysis showed that the offspring number was positively correlated with the cephalothorax width of female spider in Asano and with the nest size in Katano. These results suggest that the offspring number in this spider is affected by the female size or the nest size, probably depending on environmental factors.View full abstractDownload PDF (770K)
