摘要
本文记述了危害林木的短肛棒(虫脩)属三个新种。模式标本存放于北京林业大学。自1985年以来,陕西省平利县,甘肃省崇信县先后发生几种竹节虫危害。它们不但为害多种林木,并能转移到多种农作物上为害,发生中心,每株树上多达数百头害虫。发生面积均在万亩以上,因此给农林业生产带来了巨大损失。这几种竹节虫经鉴定属于短肛棒(虫脩)属Baculum Saussure,隶属于(虫脩)科Phasmatidae,短肛棒(虫脩)族Baculini。该属为一较大的属(近百种),在我国种类也较多。
In this paper, three new species of Baculum infesting forest from China are described. All the type specimens are kept in Beijing Forestry University. All measurements in descriptions are in mm.
1. Baculum chogxinense sp.nov. (figs. 1,2)
This species is allied to B. chinense (Brunner), but differs from it in the body rather small, spines between eyes black and small, middle femo- ra with few denticles,median segment width a little longer than length and 6th median elevation not distinct.
Body 77.1; pronotum 2.4; mesonotum 14.3; metanotum(+ median segment) 12.4; median segment 2.4; abdomen 44.2; first tergite 4.2; ninth tergite 2.8; front, middle and hind femora respectively 19.6, 15.2, 14.0.
Male: unknown
Holotype ♀, paratype 1♀, Chongxin, Gansu, Ⅶ-22-1988, Collected by Xue Lianshe.
2. Baculutn intersulcatum sp.nov. (figs. 3,4)
This species is related to B. irregulariter-dentatum (Brunner), but differs from it in with lamellae on the apical portions of middle and hind femora, middle femora shorter than mesonotum.
Body 88.3-98.5; pronotum 3.2-3.4; mesonotum18.0-20.2, metanotum (+median segment) 14.2-16.0; median segment 2.8-3.0; abdomen 48.9-54.9; first tergite 5.4-5.8; ninth tergite 3.0-3.2; operculum 8.4-9.6; front, middle and hind femora respectively 29.5-31.5, 17.4-19.5, 21.0-24.5.
Male: unknown.
Holotype ♀, Shaanxi, 1986, collected by Northern Forestry College, paratypes 4♀♀, Pingli, Shaanxi, Ⅶ-1985, collected by Zou Enhong.
3. Baculum pingliense sp.nov. (figs. 5,6)
This species comes near to B. intersulcatum, but can be separated by without head spines, thorax and abdomen with longitudinal suture instead of carina, the apex of 9th tergite not truncate, operculum exceeds beyond supraanal plate.
Body 94.4-99; pronotum 3.0-3.2; mesonotum19.2-21.2; metanotum (+median segment) 16-17; median segment 3.0-3.1; abdomen 51.6-52.4; first tergite 6-6.2; ninth tergite 2.8; front femora 31; middle femora 20; hind femora 23.5-24.5.
Male: unknown.
Holotype ♀, paratypes 4♀♀, Pingli, Shaanxi, Ⅶ-1985, collected by Zou En-hong.
