Four new species of the Diplectanidae from the gills of freshwater sciaenid species (Pachyurinae) in Brazil are described and two new genera, Anoplectanum n. g. and Spinomatrix n. g., are proposed. These are: Diplectanum copiosum n. sp. from Pachyurus junki and Petilipinnis grunniens; Anoplectanum haptorodynatum n. g., n. sp. from Pachyurus junki and Petilipinnis grunniens, and A. microsoma n. g., n. sp. from Petilipinnis grunniens, all in the Tocantins Basin; and Spinomatrix penteormos n. g., n. sp. from Pachyurus adspersus in the Rio Doce Basin. Anoplectanum is proposed to accommodate diplectanids lacking squamodiscs and having a superficial root of the ventral anchor as long or longer than the deep root. Spinomatrix is proposed for species having a haptoral and peduncular armature composed of spines, hooks, anchors, squamodiscs and armed muscular pads.
本文描述了来自巴西淡水石首鱼科物种（厚尾石首鱼亚科）鳃上的双鳞盘虫科的四个新物种，并提出了两个新属，即新属无鳞盘双鳞盘虫属（Anoplectanum n. g.）和棘盘双鳞盘虫属（Spinomatrix n. g.）。这些新物种分别是：采自容氏厚尾石首鱼和咕噜小鳍石首鱼的丰富双鳞盘虫（Diplectanum copiosum n. sp.）；采自容氏厚尾石首鱼和咕噜小鳍石首鱼的具强钩无鳞盘双鳞盘虫（Anoplectanum haptorodynatum n. g., n. sp.），以及采自咕噜小鳍石首鱼的微体无鳞盘双鳞盘虫（A. microsoma n. g., n. sp.），均来自托坎廷斯河流域；还有采自多斯河盆地的散点厚尾石首鱼的五棘棘盘双鳞盘虫（Spinomatrix penteormos n. g., n. sp.）。无鳞盘双鳞盘虫属被提出用于容纳那些没有鳞盘且腹锚浅根与深根等长或更长的双鳞盘虫。棘盘双鳞盘虫属则是为具有由刺、钩、锚、鳞盘和武装肌肉垫组成的交接器和柄部结构的物种而设立。
