Six species of Paratylenchus Micoletzky, 1922, two of them new, are reported from the Amazon Basin of Brazil. P. colbrani is reported for the first time in Brazil. Extended ranges, along with additional measurements and descriptions, are given for P. leptus, P. salubris, and P. perlatus. P. mimulus Raski, 1975 is synonymized with P. salubris Raski, 1975. P. flectospiculus n. sp. is distinguished by four lines in the lateral field, short stylet (21-24 mum), and spicules with distinct distal bend ventrad. P. rostrocaudatus n. sp. is distinguished by three lines in the lateral field, short stylet (15-16 mum), and beaked tail terminus.
报道了采自巴西亚马逊河流域的6种小环线虫属(Paratylenchus Micoletzky,1922)线虫,其中2个为新种。巴西首次报道了科氏小环线虫(P. colbrani)。给出了细弱小环线虫(P. leptus)、有益小环线虫(P. salubris)和具翼小环线虫(P. perlatus)的扩展分布范围,以及补充测量数据和描述。1975年的拟态小环线虫(P. mimulus Raski)被认定为1975年的有益小环线虫(P. salubris Raski)的同物异名。弯刺小环线虫新种(P. flectospiculus n. sp.)的特征为侧区有4条线纹、口针短(21 - 24μm)、交合刺远端向腹面明显弯曲。喙尾小环线虫新种(P. rostrocaudatus n. sp.)的特征为侧区有3条线纹、口针短(15 - 16μm)、尾端具喙。
