Dacrysoma imitatum  sp. n.

(Figs.16, 49, 70, 88, 97)

Habitus Fig. 16. Length. 0.80–0.81 mm. Colour: dusky yellow, pronotum slightly darker than elytra, antennae and legs paler yellow. Antennomeres 3–11 Fig. 49View FIGURES 41 – 55. Pronotum 0.22 mm long, 0.28 mm wide, Fig. 70View FIGURES 62 – 76, +/- 8 punctures between anterior and posterior margins. Elytra: 0.49 mm long, 0.48 mm wide, more finely punctured than pronotum.

Male: aedeagus Fig. 97.

Female: spermatheca Fig. 88View FIGURES 77 – 89.

Etymology. This epithet is based on the Latin participle imitatus, meaning imitated, and refers to its morphological similarity with sibling species.

Remarks. Difficult to distinquish on external features so that a dissection of the genitalia is required. The spermatheca could be confused with D. fabrum  but is rounder and lacks the distinctive pear shape of that species.
