根据分子和形态数据,我们描述了来自南乔治亚峡湾沿岸带(21-250m)的三个新属和四个新种的单菌。阿尔巴根。11月。sp.11月。(分支A)有一个细长的,亚圆柱试验,359-688µm长,一些碎屑附着在有机墙上。希拉·阿尔根塔吉创。11月。sp.11月。(分支Y)有一个圆柱形,精细凝集测试,535-755µm长。假征服者双凸透镜。11月。sp.11月。分枝分开。它有一个纺锤形,精细凝集测试,280-574µm长。橄榄吸潮症。11月。(进化枝C)具有卵形有机壁测试,369-433µm长。我们介绍了最初来自南乔治亚的两种单酰胺物种的第一个遗传数据,白海马(C枝)和水蛭(D枝),以及最初从McMurdoSound描述的C.delacai(CladeJ)的单个序列,南极洲。此外,我们报告了9个未描述的物种在6个不同的单层聚酰胺分支中分枝(A,B,BM,C,J,Y),其中八人在南乔治亚附近取样,一人从斯坦利附近的福克兰群岛收集。
Based on molecular and morphological data, we describe three new genera and four new species of monothalamids from the sublittoral zone (21-250 m) in South Georgia fjords that belong to different monothalamid clades. Limaxia alba gen. nov. sp. nov. (Clade A) has an elongate, subcylindrical test, 359-688 µm long, with some detritus attached to the organic wall. Hilla argentea gen. nov. sp. nov. (Clade Y) has a cylindrical, finely agglutinated test, 535-755 µm long. Pseudoconqueria lenticularis gen. nov. sp. nov. branches separately. It has a spindle-shaped, finely agglutinated test, 280-574 µm long. Bathyallogromia olivacea sp. nov. (Clade C) has an ovate organic-walled test, 369-433 µm long. We present the first genetic data on two monothalamid species originally described from South Georgia, Hippocrepinella alba (Clade C) and Hippocrepinella hirudinea (Clade D), as well as a single sequence for C. delacai (Clade J) originally described from McMurdo Sound, Antarctica. In addition, we report nine undescribed species branching in six different monothalamid clades (A, B, BM, C, J, Y), eight of them sampled around South Georgia and one collected from the Falkland Islands near Stanley.
