A new species of freshwater anomuran, Aegla nebeccana n. sp. (Decapoda: Aeglidae), is described from the Ivaí River sub-basin, a tributary of the Paraná River Basin, in Paraná state, southern Brazil. The species is illustrated in detail with drawings and photographs. It can be distinguished from its congeners based on both morphological and molecular evidence. Morphologically, the new species resembles Aegla meloi Bond-Buckup Santos, 2015 by the general shape of the carapace and chelipeds, but differs by having a developed protograstic lobe and by the cheliped ischium ornamentation. Aegla nebeccana n. sp. has pronounced protogastric lobes, similar to Aegla castro Schmitt, 1942 and Aegla schimitti Bond-Buckup Buckup, 1994 but differs clearly from these in relation to the morphology of the cheliped palmar crest. Based on molecular analysis, A. nebeccana is sister species of Aegla parva Bond-Buckup Buckup 1994.
一种新的淡水异尾类物种，内贝卡纳艾氏蟹（Aegla nebeccana n. sp.）（十足目：艾氏蟹科），是在巴西南部巴拉那州巴拉那河流域的一条支流伊瓦伊河次流域发现并被描述的。该物种通过绘图和照片进行了详细展示。基于形态学和分子证据，它可以与其同属物种区分开来。在形态上，新物种在头胸甲和螯足的总体形状上与2015年发现的梅洛艾氏蟹（Aegla meloi Bond-Buckup Santos）相似，但具有发育良好的前胃叶以及螯足坐骨的纹饰与之不同。内贝卡纳艾氏蟹有明显的前胃叶，类似于1942年发现的卡斯特罗艾氏蟹（Aegla castro Schmitt）和1994年发现的施密蒂艾氏蟹（Aegla schimitti Bond-Buckup Buckup），但在螯足掌嵴的形态上与之有明显差异。基于分子分析，内贝卡纳艾氏蟹是1994年发现的小艾氏蟹（Aegla parva Bond-Buckup Buckup）的姐妹物种。
