( Figs. 8 , 53 , 74 , 99)

Habitus Fig. 8 . Length. 0.85 mm. Colour brown, antennae and legs yellow. Antennomeres 3–11 Fig.53 . Head pubescence very long (as fig. 61). Pronotum 0.23 mm long, 0.32 mm wide, Fig. 74 , pubescence very long, puncturation very shallow and hardly visible in some lights, +/- 6 punctures between the anterior and posterior margins. Elytra 0.56 mm long, 0.46 mm wide, more finely and densely punctured than pronotum, pubescence as pronotum.

Etymology. This epithet is taken from the Latin adjective fusus, meaning flowing, and refers to the long pubescence.

Remarks. Distinquished by the broad pronotum, long pubescence, comparatively long elytra, and by the form of the aedeagus.
