Erigomicronus new genus is erected for Oreonetides longembolus Wunderlich Li, 1995 (the type species) and Maro lautus Saito, 1984. The genitalia of both species are studied in detail and illustrated. Based to the male palp conformation, the new genus seems to belong to the subfamily Erigoninae, but the epigynum resembles that of some "micronetine" genera, e.g. Maro O. Pickard-Cambridge, 1906, Oreonetides Strand, 1901, etc., based on the presence of a scape-like projection in the epigynum. All records of M. lautus from Russia are erroneous and actually refer to O. longembolus.
新属Erigomicronus是为1995年的长栓奥氏蛛（模式种）和1984年的宽大马氏蛛而建立。对这两个物种的生殖器进行了详细研究并绘图。基于雄蛛触肢形态，新属似乎属于艾蛛亚科，但基于外雌器中存在一个柄状突起，外雌器类似于一些“微蛛亚科”属，如1906年的马氏蛛、1901年的奥氏蛛等。来自俄罗斯的所有宽大马氏蛛记录都是错误的，实际上指的是长栓奥氏蛛。
