Etymology: The specific epithet is an adjective composed of the Latin noun fibula (clip) and the Latin suffix (-ferum: carrying). It alludes to the shape of the internal structure of the aedeagus.

Description: Body length 0.9-1.1 mm; habitus (Fig. 9) slender. Body yellowishred to pale reddish.

Eyes composed of 3-4 ommatidia without, or with very weak pigmentation. Punctation of pronotum dense and fine, but more distinct than that of elytra. Elytra slender, but broader than pronotum, anteriorly with small tomentose impressions; humeral carinae distinct, approximately as long as combined length of the basal four antennomeres. Hind wings completely reduced.

♂: protibia unmodified; metaventrite depressed, but not distinctly impressed; aedeagus (Figs 34-36) 0.25-0.27 mm long; ventral process apically weakly bisinuate; internal sac with clip-shaped apico-median structure; paramere thin, apically slightly extending beyond apex of median lobe and with short apical seta.

Comparative notes: This species is characterized particularly by the shapes of the aedeagus and its internal structures.

Distribution and natural history: The type specimens were found in several localities in Fthiotis and in the northern and central Pelopónnisos. Those from Fthiotis were sifted in a fir forest and in a subalpine pasture at altitudes of 1200 and 1450 m.
