Wang, Zhao & Ren (2009b) erected the species Juraphilopotamus
lubricus based on a single specimen from
the Daohugou locality, and placed it to the family Philopotamidae,
based on wing venation characters. The
argument proposed by Wang et al. (2009b; Fig. 3) for
this assignment, based on family diagnosis in Carpenter
(1992, p. 363), was ‘discoidal cell and medial cell
closed’. It is worth mentioning that traditionally the
wing venation characters are widely used for the taxonomy
of fossil Trichoptera. However these characters
can prove insufficient for family diagnoses, and should
ideally be complemented by body characters (Ivanov &
Melnitsky 2006; also, the polarity of wing characters
was never tested).
