Supplementary description
The description below concentrates in particular on amplifying Johnson’s description with more details of the meso- and metaventral characters in order to conform with the present paper.
SIZE. Habitus ( Fig. 20 A View Fig ), length 0.78 mm.
COLOUR. Dusky yellow.
HEAD. With a shallow linear depression and short medial longitudinal depression between the eyes, width across eyes 0.21 mm; antennomeres III–XI length 0.39 mm, III–IX 0.23 mm, X–XI length 0.16 mm globular; mentum and prementum as Fig.4 A. View Fig
PRONOTUM. Length 0.20mm, width 0.30 mm, widest along the posterior margin, pubescent, with a row of eight foveae along the base, the outer two on each side smaller than the inner four; lateral margins evenly rounded anteriorly and slightly concave posteriorly before the acute hind angles, bordered, the border
continuing for a short distance along the posterior margin which has a sinuous emargination before the scutellum ( Fig. 20 B View Fig ).
ELYTRA. Length 0.53 mm, width 0.43 mm, pubescent, foveolate.
MESOVENTRITE. Medial extension of collar widening posteriorly; mid-keel short with concave sides, posterior corners with narrow carinae to mesocoxal anterior margins, raised sharply to keel base; keel with ± two setae, narrow, tapering to termination between the mesocoxae; mesoventral lateral margins serrate in posterior half; humeri strongly toothed ( Fig. 20 C View Fig ).
METAVENTRITE. Length 0.19 mm, width across spines 0.14 mm; posterior margins of mesocoxal cavities not serrate.
WINGS. Micropterous.
GENITALIA. Male aedeagus as Fig. 6 View Fig Fa–b. Female spermatheca globular.
Remarks
Described by Johnson on the basis of a single female from New Zealand, North Island, Northland, Parahaki, Whangerei, mixed leaf litter, 8. xi.1956, leg. R.A. Crowson (NZAC). Distinguished from C. foveolatum Johnson, 1982 , the only other Cissidium reported from New Zealand, by the smaller foveae on the basal margin of the pronotum.
