A new deep-sea genus of the asellotan family Munnopsidae Lilljeborg, 1864, Pirinectes Malyutina & Brix gen. nov., including two new species, is described from the abyssal manganese nodule area of the Clarion Clipperton Fracture Zone in the north-eastern tropical Pacific. The new genus of the subfamily Eurycopinae Hansen, 1916, which is distinguished genetically, differs morphologically from the other six genera of this subfamily by the unique combination of the following characters: a rostrum approximately one third of the cephalon width and as long as antenna I article 1, with rounded margins, and the fingerprint pattern surface; pereonites 5 and 6 are fused dorsomedially, pereonite 7 is free; antenna I article 1 is without distomedial lobe and with small a distolateral projection; epipod of the maxilliped is less than two thirds of basis length and ovoid. Unique for the subfamily is the long pereopod II ischium, which is longer than the basis. Such characteristics can only be found in some munnopsid genera of the subfamily Munnopsinae Lilljeborg, 1864. Confirmed as distinct species by genetic analysis, the two new species can be morphologically distinguished from each other via a difference in width of the cephalon rostrum, the length of the palp and epipod of the maxilliped, length and width of distomedial lobes of pleopod 1, the width of carpi of the pereopods I, V and VI, and the different ratio of the uropod rami length. An illustrated identification key to the species of the Pirinectes gen. nov. is presented.

Munnopsidae Lilljeborg的一个新属，1864年（甲壳纲，伊索波达），描述了来自东北热带太平洋克拉里昂克利珀顿断裂带的两个深渊新物种

Asellotan家族Munnopsidae Lilljeborg的一个新的深海属，1864年，PirinectesMalyutina＆Brix gen。东北热带太平洋克拉里昂克利珀顿断裂带的深海锰结核区域描述了包括两个新物种在内的11月。遗传上有区别的Eurycopinae Hansen亚科的新属，在1916年在形态上不同于该亚科的其他六个属，其特征在于以下特征的独特组合：讲台约头颈宽度的三分之一，且与触角I一样长第1条，具有圆形的边缘和指纹图案的表面；钙钛矿5和6背靠地熔合，钙钛矿7是游离​​的。我的第1条天线没有节肢状的瓣，小到外侧突。足突的足足不到基长和卵球形的三分之二。亚科独有的是长脚骨II坐骨，比基础要长。仅在1864年的Munnopsinae Lilljeborg子家族的某些munnopsid属中才能发现这种特征。通过遗传分析确认这两个新物种为形态独特的物种，可以通过头枕的宽度，足节1的最大足的掌和脚掌，节足的长度和宽度，袋足I，V和VI的腕腕的宽度，以及足足拉米长度的不同比例。图示说明物种的关键 这两种新物种在形态上可以通过头枕的宽度，最大足的脚掌和脚掌的长度，胸足的解剖足的长度和宽度，足骨的腕骨的宽度I的差异来区分。 ，V和VI，以及尾足拉米长度的不同比例。图示说明物种的关键 这两种新物种在形态上可以通过头枕的宽度，最大足的脚掌和脚掌的长度，胸足的解剖足的长度和宽度，足骨的腕骨的宽度I的差异来区分。 ，V和VI，以及尾足拉米长度的不同比例。图示说明物种的关键Pirinectes gen。十一月 被呈现。
