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. 94A), length 0.80 mm.

COLOUR. Yellow brown, antennae and legs dusky yellow.

HEAD. Width across eyes 0.22 mm; antennomeres 3–11 length 0.45 mm long (Fig. 2F); mentum as Fig. 4B.

PRONOTUM. Length 0.19 mm, width 0.28 mm, sparsely pubescent and foveolate; lateral margins sharply angled, strongly concave posteriad to rectangular hind angles, less markedly concave anteriorly to distinct obtusely rounded front angles (Fig. 94B).

ELYTRA. 0.55 mm long, 0.41 mm wide, pubescence a little shorter and more decumbent than on the pronotum.

MESOVENTRITE. Median process of the very narrow collar pointed; mid-keel strongly widened anteriorly, hind angles with carinae to mesocoxal anterior borders, bluntly raised medially before junction with keel; keel with ± five setae, parallel-sided to rounded termination at base of mesocoxae (Fig. 5F); humeri toothed with flat, sharply pointed carinae reaching posteriorly to mid-point of mesoventrite, mesoventral lateral margins entirely effaced, present as apodemes (Fig. 94C).

METAVENTRITE. Spines very small.

GENITALIA. Female spermatheca globular. Males not known.

Remarks

Differs from the other Bolivian Cissidium, except C. sawadai Darby, 2015, by the long and narrow elytra and distinguishable from that species by the strongly tapering mid-keel.
