Niphargus sp.

Published records: L.15—Namur (Leruth 1934a); L.112—Saine Anne cave (Leruth 1934a); L.119—Lyell cave (Leruth 1934a).

New records: L.83—Collemboles cave (12.7.2004, AB); L.125—Bruta, spring (9.2.2005, MD); L.142— Chartreuse, mine gallery (17.12.2002, MD & JMH); L.148—Rhieux, underground brook (18.3.2002, MD & JMH).

Leruth (1934a) mentions a finding of Niphargus sp. in Namur, and an unknown subspecies of N. kochianus subsp. from the other two localities. As this subspecies could not be attributed to species level, we rather consider such records as Niphargus sp. Specimens in new material were either to small for identification, or did not exhibit enough specific characters for unambiguous species determination (for distribution see Fig. 6).
