Abstract: 139 Euura clitellata group We recognize six species in the group, but nuclear data strongly suggest that E. clitellata contains at least four species and E. fallax probably three. Additional research (particularly to sequence nuclear genes of more specimens to assess morphological variability) is necessary to better associate type specimens with putative species suggested by nuclear genes. Euura vaga, although morphologically a member of the group, is excluded because based on genetics it seems to be about as distant to the clitellata group as to other species groups. Claws with small subapical tooth and characters of lancet (no setae, sutures strongly bending apically, basal serrulae not strongly projecting posteriorly) and valvula 3 (in dorsal view distinctly broadened at base) distinguish the females from those of the other Euura groups and from E. vaga (basal serrulae strongly projecting posteriorly). Males have distinct penis valves enabling reliable identification of species (except within E. clitellata if these are split into additional species). The width of the mesocutellum seems to correlate positively with the extent of expansion of the head. The E. clitellata subgroup and E. fallax usually have very pale heads, whereas E. moerens, E. lichtwardti and E. clibrichella have much darker heads.
