Dacrysoma dolorosum  sp. n.

( Figs. 46View FIGURES 41 – 55, 67View FIGURES 62 – 76, 96)

This species exists as a single dissection making a habitus photograph impossible. Length. 0.80–0.81 mm. Colour: dusky yellow, antennae paler yellow. Antennae: the stalk of the dumb-bell shaped antennomere 11 very long Fig. 46View FIGURES 41 – 55. Head pubescence very long (as Fig. 61View FIGURES 56 – 61). Pronotum Fig. 67View FIGURES 62 – 76, 0.21 mm long, 0.29 mm wide, lateral margins strongly angled, pubescence very long, foveae moderate/coarse, +/- 7 between anterior and posterior margins. Elytra: 0.49 mm long, 0.46 mm wide, foveae moderate, pubescence shorter than on head and pronotum.

Male: aedeagus Fig. 96.

Female: not known.

Etymology. This epithet is taken from an adjectival form of the Latin noun dolor, meaning sad, and reflects the mournful impression given by the appearance of the downwardly pointing tip of the aedeagus and the fragmentary nature of the specimen.

Remarks. Immediately distinguishable by the very long bar to the dumb-bell shaped antennomere 11, a character which is shared by only one other species, D. longulum  , from which it may be separated by the form of the pronotum with more strongly angled lateral margins, and the more hooked shape of the aedeagus with a narrowed tip.
