Cissidium lisae sp. n.

Figures 7 , 13 , 16 , 23 , 33 , 39

Habitus Fig. 7 . Length 0.80 mm. Colour: yellow brown, antennae and legs dusky yellow. Antennomeres 3–11 length 0.45 mm long, segments 9–11 together longer than 3–8, with long projecting setae, Fig. 23 . Width across eyes 0.22 mm. Mentum slightly tapering inwards towards base and with slightly swelling sides in basal third.

Pronotum: length 0.19 mm, width 0.28 mm, lateral margins angled, Fig. 16 . Elytra 0.55 mm long, 0.41 mm wide, pubescence a little shorter and more decumbent than on the pronotum. Mesoventrum Fig 13 . Metaventrum posterior margin between metacoxae with two very small lateral points, Fig. 33 . Spermatheca globular, Fig. 39 . Males unknown.

Etymology. Named after Dr Elisabeth Darby, my wife, who has graciously put up with the beetles for more than thirty years.

Diagnosis. Differs from all other Cissidium except elongatum on the long and narrow elytra but distinguishable from that species by the longer terminal antennomeres with longer setae.
