THE CLASSIFICATON OF SPRINGTAILS OF FAMILY NEELIDAE AND THE NEW RECORDS FROM CHINA(COLLEMBOLA,SYMPHYPLEONA)

本文论述了短角园跳科分类的基本概况,报道了我国首次发现的短角园跳虫四个中国新纪录,即:1.Neelus(Neelus)mirinus Folsomi,短角红园跳(中文名称自拟)2.Neelus(Megalothorax) minimus Willem,短角巨胸红园跳(中文名称自拟)3.Neelus(Megalotgorax)incertus(Boner),短角巨胸白园跳(中文名称自拟)4.Neelus(Neelides)minutus(Folsom),拟短角小园跳(中文名称自拟)

The present paper deals with the classification of springtails of the family Neelidae.and 4 new records from china are reported。 According to Christiansen and Bellinger's system,this family hat a single genus Neelus,consisting 21 species involved in three subgenus:subgenus (Neelus)subgenus(Megalothorax)and subgenus(Neelides)。 The species of this family are extremly small(maximUm lengthO.6—0.7mm) and characterized by having the antennae much shorter than head,no eyes, and dentes subdivided into 2 parts.The thorax is relatively large,the posterior trunk segments form a single mass,only the prothorax and sometimes the mesothorax set off with distinct suture.The head and the body have more or less clearly demarcated sensory fields bearing speeialized setae.An apical ventral process on the manubrium and a basal dental process form a supplem- entary articulation between these segments。 4 species collected from China are new records.They are: 1,Neelus(Neelus)mirinus Folsom 2,Neelus(Megalothorax)minimus willem 3,Neelus(Megalothorax)incertus(Boner) 4,Neelus(Neelides)minutus(Folson)
