DescriptionLimnobaris dolorosa has characteristic ventrolateral vestiture of dense, squamiform setae, which occurs also in Limnobaris t-album and Limnobaris japonica. All three species can be distinguished from each other based on details of the male genitalia and vestiture. In addition, Limnobaris japonica is allopatric (see under this species for further details). The safest way to separate Limnobaris dolorosa from Limnobaris t-album is the short and wide penis (Figs 6, 7). Moreover, Limnobaris dolorosa has evenly dense vestiture on the entire flank, whereas Limnobaris t-album usually has less dense vestiture on the first ventrites and the metasternum.
