Description (based on Norwegian specimens, diagnostic characters in italics):
Eye bridge consisting of 4 rows of facets.
Flagellomere 14 with an unusually elongate apiculus for a
Pericoma (see note below).
Gonocoxites very stout
without mesal apodemes. Gonostylus with a long narrow part and a thickened base.
Inner lamellae distally terminating behind outer lamellae. Subgenital plate deeply bilobate,
aedeagal armature with transverse rows of ridges anterior to edge of subgenital plate.
5-7 spatulate retinacula.

Pericoma bavarica Wagner, 1981)

Natural History:
Unknown.
Discussion:
Wagner (1981) described
Pericoma bavarica from Germany. The synonymy with
Pericoma rivularis is not obvious from the illustrations, but is clear from the actual specimens.
Omelková & Ježek (2012) placed
Pericoma rivularis in
Pneumia Enderlein, 1935 based on the elongate apiculus on the terminal flagellomere. Kvifte & Andersen (2012) pointed out that
Pneumia typically have retinacula with feathery tips and eyebridges of six or seven facets and argued that the elongate apiculus is a plesiomorphy of little value in classification. The placement of
Pericoma rivularis is still unclear.
