description: Key to genera of Cyllodini occurring in Australia
1. Mesoventrite with anterior edge strongly oblique, almost vertical, so that most of its surface, including a median carina, is higher (in ventral view, projecting towards the observer) than mesocoxae or metaventrite; metanepisternum less than 3× as long as wide and more or less parallel-sided; mandibular apex unidentate and simple (without serrations or spines); pronotum at least slightly wider than combined elytra (Figs 1, 3); elytra shorter than their combined widths; elytral punctures not forming distinct rows; length at least 4.5 mm; gonocoxites narrowly elongate, parallel-sided and subcontiguous, with distinct, elongate, parallel-sided, apical gonostyli (Fig. 59); northern NSW & southern QLD; associated with Opuntia cacti..................................................................................................... Camptodes Erichson
- Mesoventrite with anterior edge flat or weakly carinate and any change in elevation occurring only at posterior end; metanepisternum more than 3.5× as long as wide and distinctly narrowed posteriorly (Fig. 14); pronotum not wider than combined elytra (Figs 2, 4); mandibular apex, IF unidentate, THEN armed with serrations or spines; IF length greater than 4 mm, elytra distinctly longer than wide; ovipositor never with elongate, parallel-sided, apical gonostyli; associated with various fungi..... 2
2 (1). Labrum wider than clypeus, consisting of a pair of diverging, rounded lobes flanking a deep notch widest at its opening, narrowing posteriorly and almost reaching the labral base; outer apical angle of protibia with distinct tooth; length always greater than 3.5 mm; associated with the fruiting bodies of Phallales ................................. Gymnocychramus Lea
- Labrum never as above, widest at base and not wider than clypeus, its apex usually with small median cleft with parallel sides; outer apical angle of protibia without distinct tooth; length never greater than 3.5 mm; associated with the non-woody fruiting bodies of Basidiomycetes (mushrooms).................................................................... 3
3 (2). Mesoventrite with anterior edge on a distinctly different plane than metaventrite, its posterior end more or less vertical and emarginate forming a pair of mesothoracic lobes flanking the truncate anterior edge of metaventrite and visible in ventral view (Figs 50–51); posterior edges of mesocoxal cavities not joined by curved line extending across anterior process of metaventrite.................................................................................................... 4
- Mesoventrite with anterior edge on the same plane as or a slightly different plane than metaventrite, its posterior end emarginate but horizontal or only slightly oblique (Figs 52–53); posterior edges of mesocoxal cavities joined by curved line extending across anterior process of metaventrite (Figs. 52–53).......................................................... 5
4(3). Upper portion of body strongly convex (Fig. 10); lateral margins of elytra not visible from above (Fig. 2); frontoclypeal suture absent; vertexal line present at sides; mandible unidentate with dorsal and ventral serrations; all basal tarsomeres lobed; abdominal ventrite 1 without postcoxal lines.................................................. Cyllodes Erichson
- Upper portion of body only slightly convex (Fig. 9); lateral margins of elytra visible for their entire lengths from above (Fig. 5); frontoclypeal suture present (sometimes weakly indicated externally); vertexal line absent; mandible bidentate with dorsal lobe serrate; no basal tarsomeres lobed; abdominal ventrite 1 with postcoxal lines................ Cyllopallodes, gen. nov.
5(3). Prosternum in front of coxa very short, less than 0.3× as long as mid length of a coxal cavity; mesal portion of prosternum with median carina extending beyond middle of prosternal process; anterior portion of mesoventrite (Fig. 52) with a pair of procoxal rests divided by a pair of posteriorly diverging carinae; metaventrite with short discrimen; axillary spaces absent; outer edge of mesotibia (Fig. 56) evenly curved and usuallly widest just beyond middle; ovipositor (Fig. 43) with broadly truncate apex.............................................................................. Coxollodes Kirejtshuk
- Prosternum about 0.5× as long as mid length of coxal cavity, without or with weak median carina and sometimes with acute anterior projection; anterior portion of mesoventrite (Fig. 53) with short longitudinal carina and no procoxal rests; metaventrite without discrimen; axillary spaces (Fig. 54) usually well developed; outer edge of mesotibia in Australian species (Figs 57–58) subapically angulate; ovipositor with acute apex (Figs 48–49).................................... Pallodes Erichson
