Dacrysoma fabrum sp. n

(Figs. 11, 48, 59, 69, 86, 95)

Habitus Fig. 11. Length. 0.80–0.81 mm. Colour: yellowy brown, antennae and legs paler yellow. Antennae very short, antennomeres 3–11 Fig. 48. Pronotum: 0.21 mm long, 0.28 mm wide, puncturation very faint, Figs 59, 69. Elytra: 0.54 mm long, 0.45 mm wide, puncturation stronger than on pronotum.

Male: aedeagus Fig. 95.

Female: spermatheca Fig. 86.

Etymology. This epithet is taken from the Latin adjective faber, meaning ingenious, and refers to the joined nature of the dumb-bell shaped antennomere 11.

Remarks. The absence of clear pronotal puncturation is similar to D. fusum, but D. fabrum may be separated from that and all other Dacrysoma species examined to date except D. denticulatum by the absence of a clearly defined dumb-bell shape to antennomere 11 which shows only a slight median narrowing. See D. longulum for the possibility that females of that species may be confused with females of D. fabrum
