Supplementary description

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

SIZE. Habitus ( Fig. 47A View Fig ), length 0.78 mm.

COLOUR. Dusky yellow, legs and antennae a little paler.

HEAD. Antennomeres III–XI length 0.38 mm, III–IX length 0.19 mm, X–XI length 0.19 mm; width across eyes 0.21 mm; mentum and submentum ( Fig. 4C View Fig ).

PRONOTUM. Length 0.31 mm, width, 0.20 mm, shining, pubescent; lateral margins slightly angled medially, concave to rectangular hind angles, bordered, the border continuing along the posterior margin, medial emargination before scutellum sinuous. ( Fig. 47B View Fig ).

ELYTRA. 0.47 mm long, 0.38 mm wide.

MESOVENTRITE. Medial extension of collar, broad, parallel-sided; mid-keel widest posteriorly, hind angles not reaching mesocoxal borders; keel long, with 4 setae, tapering narrowly to point at the base of the mesocoxae; mesoventral lateral margins evenly rounded without serrations; humeri toothed, posterior margin sloping strongly posteriad ( Fig. 47C View Fig ).

METAVENTRITE. Pubescent, length 1.10 mm, width across spines 0.85 mm, disc simple.

GENITALIA. Female spermatheca globular ( Fig. 6B View Fig ). Male aedeagus pointed, not so beak-shaped as many species and with 15 short, thick, blunt setae on ventrite VIII ( Fig. 7G View Fig ).

Remarks

The form of antennomere XI with a short median interruption and the sinuate posterior margin of the pronotum before the hind angles distinguish this species from the other Bolivian Cissidium .
