Key to species of Cadoderus

1 Rostrum broader; lateral carinae broadly convex; pterygia extended beyond lateral contour of rostrum; epistome separated from frons by carina, glabrous; antennal scape squamose; tarsi setose and with scattered scales; elytra without transverse band on posterior declivity, spotted pattern absent; green scales form distinct longitudinal stripes on elytra and pronotum; ventral side of head and pronotum green; pronotum widest at middle; elytral disc strongly convex (observable in lateral view) (figs 1–2, 5–10); apex of median lobe without dorsal tooth-shaped process (observable in lateral view, Figs 70, 97), otherwise angulate flange developed ( Fig. 59); coxites curved dorso-ventrally, with heavily sclerotized dorsal baculi; cornus of spermatheca extended beyond corpus............................................................................... 2

- Rostrum narrower; lateral carinae vestigial; pterygia extended beyond lateral contour of rostrum; epistome fused with frons in fronto-epistome, not delimited by carina, coarsely punctate; antennal scapes without scales; elytral disc weakly convex; tarsi setose, without scales; elytra with pale transverse band on posterior declivity and scattered deep-brown unclear spots on intervals 1, 2, 4, 6; green scales scattered; ventral side of head and pronotum grey; pronotum widest in posterior half; elytral disc slightly convex (figs 3–4); apex of median lobe with dorsal tooth-shaped process directed posteriad ( Fig. 122); coxites not curved dorso-ventrally, without heavily sclerotized dorsal baculi; cornus of spermatheca not extended beyond corpus............................................................................................

3 Anterior declivity with setae up to a third as long as interval width; background brownish-olivaceous; striped pattern formed by green and cupreous scales; pronotum with 3 longitudinal cupreous stripes (1 discal, 2 dorso-lateral); dorso-lateral stripes broad, fused with lateral stripes; anterior portion of intervals 3 and 5 gray; rostrum with scarcely convex lateral carinae; epifrons at the level of antennal articulation 2.8–3.0 x narrower than vertex; eyes smaller [FW/ELD: average 1.43]; tubercles along striae 1 larger ( Fig. 82); setal comb of protibiae consisting of 8–9 setae; female tergite 8 with sparse setal fringe.............................................................................................. C. burundi sp. n. - Anterior declivity with setae half as long as interval width; background deep-brown or olivaceous; striped pattern formed by green and cupreous scales; pronotum with 5 longitudinal distinct stripes (1 discal, 2 dorso-lateral, 2 lateral); dorso-lateral stripes narrow; anterior portion of intervals 3 and 5 green or olivaceous-brown; rostrum with strongly convex lateral carinae; epifrons at level of antennal articulation 2 x narrower than vertex; eyes larger [FW/ELD: average 1.21–1.30]; tubercles along the striae 1 smaller; setal comb of protibiae consisting of 10–14 setae; female tergite 8 with dense setal fringe............ 4

4 Subocular row consisting of 4 setae; anterior and posterior elytral declivity with equally strongly erect setae; 2nd–3rd funicular segments with scattered scales; metatibiae with vestigial grooming brush; background scaling olivaceous; antennal funicle slender (1st funicular segment 1.42 x as long as 2nd; elytra rather broad and convex EL/EW average: 1.31, EL/BH average: 1.5; median lobe 0.75 x as long as apodemes, tubular, in apical 1/3 sharply narrowed anteriad, apex attenuate, narrowly rounded...............................................................................
