本文记述采自湖北和安徽省的胸胸棘鲷属Pielomastax Pielomastax Chang 1937两新种。模式标本保存于陕西师范大学动物研究所。1.古柳江瘤胸脂鲤，新种（图1 ~4）该新种与三齿锥胸天牛Pielomastax tridentata Wanget Zheng相似，但不同之处在于：触角的第三和第四节等长;眼距宽约为眼宽的2.5倍;产卵器的腹瓣有两个大齿和一个小齿;雌虫的下生殖板后缘中部有长方形切迹。安徽古柳江，1984年，王林采集。2.钝齿盾胸水蚤Pielomastax obtusidentata，sp. nov.（图5，6）该新种与柱尾锥胸蛾Pielomastax cylindrocerca Pielomastax Hsia et Liu关系密切，但与后者的区别在于：（1）上下瓣尖尖;（2）产卵器腹瓣有3个大钝齿;（3）雌体下生殖板后缘裂裂，裂瓣尖圆。正模标本，副模标本1，湖北：神农架（松柏），1995年2月2日，李凯采集。
This paper gives a description of two new species of the genus Pielomastax Chang 1937,collected from Hubei and Anhui Province. Type specimens are deposited in the Institute of Zoology,Shaanxi Normal University. 1. Pielomastax guliujiangensis, sp. nov.(Figs.1～4) This new species is simillar to Pielomastax tridentata Wang et Zheng,but differs in:1) third and fourth segments of antenna equal in length; 2) width of ocular distance wider than the width of an eye about 2.5 times; 3) ventral valvulae of the ovipositor with two large teeth and a small tooth; 4) subgenital plate in female with longsquare notch in the middle of hind margin. Holotype♀, paratype 1♀, Anhui:Guliujiang, Ⅷ 1984,collected by Wang Lin. 2. Pielomastax obtusidentata, sp. nov.(Figs.5,6) This new species is closely related to Pielomastax cylindrocerca Hsia et Liu, but differs from the latter in the following characters: 1) the upper and lower valvulae with the apex sharp; 2) ventral valvulae of the ovipositor with three large blunt teeth; 3) the split on posterior margin of female subgenital plate crack shape, apex of crack lobe rounded.
