摘要
自1977年以来,在我国陕西、四川、广西、广东等省陆续发现竹节虫严重为害林木和农作物。1986年四川省巫山县因竹节虫为害林木受灾面积达200余亩,山上的油桐、柏树、化香、乌桕、青冈及河边的麻柳等树叶被吃光,同时还为害玉米、马铃薯等。1989年在四川省忠县发现20余亩柏林被害仅剩光杆,一片黑褐色,状似火烧一样。
Some two hundred mu of the trees in Sichuan Province were damaged by stick insects in 1986. The damaged plants were: Vernicta forcdii. Cupressus funebris, Platycarya strobilacea, P orientalis, Sapium sebiferum, Cyclobalanopsis sp Salix cheilophila, also Zea mays, Solatium tuberosum. In 1989, more than twenty mu of Cupressus funebris were eaten by the same species pests. We examined and found out a new species of phasmides. In this paper, the new species Phobaettcus sichu anensis is described The types are preserved in the Department of Biology Nankat University. The measurements are ail in millimeters.Phobaeticus sichuanensis Cai & Liu sp. nov. (figs. 1-4)Female: fusco-testaceous; smooth. Head lateral margin pale: a pair of small spi nes between the eyes. Intermediate and posterior femura with spines on ventral ca-rina (fig. 1), two strong apical spines on ventral carina. Operculum very long,much beyond the apex of abdomen.Male: testaceous. Vertex .with a 'V' shaped furrow Four posterior temura each with a strong spine on ventral carina near the apex.length of body (except operculum) 176.0 138.6length of pronotum 7.9 5.0length of mesonotum 33.4 29.5length of metanotum (with median segment) 32.3 28.1length of median segment 4.3 3.6length of supra anal plate 0.92length of operculum 38.8length of front femora 46.0 46.8length of median femora 31.7 29.5length of hind femora 34.8 34.0Egg: griseous with irregular black maculations (tigs. 3,4). length 3.68, width-2.32, height 2.64. Holotype: female, Zhongxian, Sichuan Province, 1989 X. 9. Collectores ZengLin, Hu Liangcheng. Alotype: male, the same with holorype. Paratypes: 2, 2. Female of the new species is similar to Phobaeticu; incertus Brunner 1907, butcan be distinguished by its body bigger and the operculum a little longer than 2times of 8th, 9th and 10th tergites together (in P. incertui operculum nearly 3.times long).
