Supplementary description

The following description amplifies the type description of Darby (2015), by adding more details of the meso- and metaventral characters in order to conform with the entries in the present paper.

SIZE. Habitus (Fig. 102A), length 0.84 mm.

COLOUR. Yellowish brown, legs and antennae lighter.

HEAD. Antennomeres III–XI 0.37 mm long, III–IX 23 mm long, X–XI 0.14 mm long.

PRONOTUM. 0.34 mm wide, 0.22 mm long, with scattered pubescence and shallow foveolae; lateral margins angulate thence almost straight to obtuse anterior angles and concave to rectangular hind angles (Fig. 102B).

ELYTRA. 0.55 mm long, 0.4 mm wide, more strongly and densely foveolate than the pronotum.

MESOVENTRITE. Medial process of collar short, widening with concave sides onto the mid-keel; mid-keel parallel-sided after widening anteriorly immediately before the collar, posterior corners not extending to the mesocoxal anterior borders, medial extension to keel with ± six setae; keel with a single seta, narrow, barely tapering to point below mid-point of the mesocoxae (Fig. 5E); mesoventral lateral margins without serrations; humeri strongly toothed (Fig. 102C).

METAVENTRITE. Length 0.13 mm, sparsely pubescent, disc simple, points long tapering to setal width, distance across points 0.11 mm; posterior margins of mesocoxae without serrations.

GENITALIA. Female spermatheca elongate (Fig. 6C).

Remarks

The largest of the six Bolivian Cissidium, except for C. lisae, from which it may be separated by the shape of the mesoventral keel.
