For details, see Table 1.
b
Re-investigated; average values from detailed Table in Foissner (1989).
c
From the description and figures provided (Fig. 2a, b).
d
Assuming that his L. macrostoma is the macrostome of his L. costatus (see chapter on “Comparison with macrostome congeners”). However, we would not exclude the possibility that it is a distinct species (see chapter on “Comparison with L. costatus”).
e
Numbers based on averages from five macrostome specimens each.
MA, macrostomes; MI, microstomes.
