Darby, Michael, 2015, Studies of Bolivian Ptiliidae (Coleoptera) 1: The genus Cissidium Motschulsky with six new species, Zootaxa 3937 (1), pp. 179-190 : 183-184

Cissidium globosum sp. n.

Figures 3 , 9 , 18 , 20 , 32 , 40

Habitus Fig. 3 . Length 0.61 mm. Colour brownish yellow, legs and antennae paler. Antennomeres 3 –11 0.26 mm long, Fig. 20 . Distance across the eyes 0.19 mm. Pronotum 0.25 mm wide, 0.17 mm long, Fig. 18 . Elytra 0.41mm long, 0.35 mm wide, punctulations deeper than those on pronotum. Mesoventrum Fig. 9 . Lateral spines on posterior border of metaventrum long, Fig. 32 . Spermatheca Fig. 40 . Males unknown.

Etymology. Named after the globular appearance of antennomeres 10–11.

Diagnosis. The smallest of the Cissidium species described to date. The distinctive globular antennomeres 10–11 coupled with the short and wide form of the mesoventral keel before it meets the collar and the long points on the posterior border of the metaventrum between the metacoxae will also help to distinguish it.
