翘蛛属和金希蛛属的修订(蜘蛛目:跳蛛科)

A REVISION OF THE GENERA IURA AND KINHIA (ARANEAE:SALTICIDAE)

对跳蛛科翘蛛属(Iura)和金希蛛属(Kinhia)进行了修订,认为后者为前者的同物异名。

The present paper deals with the revision of the genera Iura and K inhia.The au-thours think the genus Kinhia is a synonym of the genus Iura.Up to now,only 4 species are reported in this genus,all 4 species are females. Its diagnostic characteristics are as follows :Body flat and broad. On the surface of abdomen there are big orange apodemes.The copulatory canals of vulva twist in 'S'-shaped.The genus Kinhia was built by Zabka in 1985 based on a male specimen. Its palpal organ with an oval bulbus and quite long embolus. A long outgrowth on the posterior-lateral surface of cymbium towards patella. Tibial apophysis rather small and usually indistinct. 5 new species were reported by Peng Xianjin and Yin Changmin in 1991. Recently, the authours studied those 5 species further and found that:1. Males and females of type specimens of the following 4 species were collected by the same collecter at the same time and in the same places. They are:Kinhia hamalapophysis,K. longioche-licera,K. yueluensis and K. yunnanensis. Male even accord with its female in the form of cephalothorax,rate of eye size and arrangement of eyes. So we think that the 4 males paired with their females by Peng Xianjin and Yin Changmin in no doubt.2. As far as males of the 5 species ,their body forms and the structures of chelicera and male palpal organ accord with the charateristics of genus Kinhia.3. In the respect of females ,their flattened and broadened bodies,big orange apodemes on the surface of abdomen and 'S'-shaped copulatory canals of vulva (expect for, K. longiochelicera) accord with the charateristics of the genus Iura. The diagnoses of the genus Iura Peckham et Peckham, 1901 are redescribed as follows:Body flat and broad. Anterior part of cephalothorax flat, posterior part narrowed and inclined ,trapezium. Eye field trapzoid,its length longer than half length of cephalothorax, 3rd eye row obviorsly wider than 1st one, 2nd eye row nearing the base of ALE. On the surface of abdomen,there are big orange apodemes or in some males indistinct. Chelicera of male without incision. Leg Ⅰ longest and robustest ,length of coxa Ⅰ longer than the total length of coxa Ⅱ and trochanter Ⅱ. Male palpal organ with a long outgrowth on the posterior-lateral surface of cymbi-um towards the patella, embolus quite long,bulbus oval,tibial apophysis rather small,usually indistinct.Female epigyne translucent, its copulatory canals twist in 'S'-shaped. Spermatheca with two or one chambers. Copulatory opening located at the behind , middle or lateral of sper-matheca. This genus relates to genus Rhene Thorell, 1869. But the latter differs from the former by the followings:1. There is a distinct incision on the paramedial edge of male chelicera;2. Male palpal organ without long outgrowth on the posterior-lateral surface of cymbium. Tibial apophysis distinct. Embolus shorter and robuster. Conductor distinct and developed ;3. Copulatory opening located at the front of spermatheca.Up to now, 10 species were reported in this genus. They are:Iura bicolor Zabka, 1985,I. hamalapophy sis (Peng et Yin , 1991) ,I. longiochelicera (Peng et Yin , 1991),I. mandarina Simon, 1903,I. prima (Zabka, 1985) ,I. pulchra Peckham Peckham , 1900,I. pygea Thorell, 1891 ,I. trigo-napophy sis (Peng et Yin, 1991) ,I. yueluensis (Peng et Yin, 1991) ,/. yunnanensis(Peng et Yin, 1991).
