Abstract

We redescribe Macrothrix rosea (females and males) based on material collected in Belgium. We also compare seven populations of Macrothrix ‘triserialis’ from different parts of the world, including a topotypical population of M. triserialis s. str. from Sri Lanka, and males from South India (here first described), relying heavily on the structure of the trunk limbs, beside classical features of morphology. M. rosea and M. triserialis are extremely closely related: males are easily separated, but the identification of females requires micro-characters such as the relative length of the apical segment of the setae natatoriae and the adornment of the first antenna and of the longest swimming seta of the antenna. M. rosea and triserialis together constitute a sub-group of the rosea-group.
