( Fig. 15D ) Pentapedilum mellense Goetghebuer, 1942: 7 . Material examined. BELGIUM : East Flanders , Melle , holotype male, 6.v.1942 , M. Goetghebuer ( IRSN ) . Diagnostic characters. Among species with numerous setae on the wing membrane, uniformly colored abdomen, foretibial scale without spur, base of superior volsella without microtrichia, and base of superior volsella with 5 inner setae, the species can be distinguished by having inferior volsella with 2 apical setae and projection of the superior volsella with 2 lateral seta placed in apical half. P . ( Pe .) pseudosordens and to some extent P . ( Pe .) kasumiense have a superior volsella with two lateral setae, but these species differ in most other details.

Projection of superior volsella ( Fig. 15E ) strongly curved with 2 lateral setae, base with 5 inner setae as opposed to the 3 inner setae indicated by Goetghebuer (1942) . Inferior volsella parallel-sided, with 2 long apical setae. Anal point tapering to parallel-sided. Distribution. Known only from Melle, Belgium .
