Key to species in the Cycloneda germainii species complex

1. Form somewhat depressed, elongate elliptical; elytral epipleuron flat, ascending externally, visible in lateral view ( Fig. 3C View FIGURE 3 ); elytron narrow, parallel­sided for much of length ( Figs. 5A–D View FIGURE 5 ); punctation on pronotum and elytron dense (separated by 1.0–2.5X a diameter), sharply defined; antenna short, composed of 10 antennomeres, strongly, abruptly clubbed ( Fig. 9D View FIGURE 9 ). Recorded from Magellanes, Chile and Tierra del Fuego, Argentina ( Fig. 10 View FIGURE 10 , triangles)......................................................... ................................................................... C. patagonica González and Vandenberg

1’. Form moderately to strongly convex, ovoid to oblong; elytral epipleuron flat to concave, approximately horizontal, not visible in lateral view or only very narrowly so in anterior half ( Figs. 3A, B, D–G View FIGURE 3 ); elytron broader, with external (lateral) bor­ der more arcuate ( Figs. 4A–P View FIGURE 4 , 5E–K View FIGURE 5 ); punctation less dense, variable, sometimes indistinct; antenna longer ( Figs. 9A–C, E–H View FIGURE 9 ), of 9–11 antennomeres, club variable. Bolivia, Chile, Argentina; not known from southeast of the straits of Magellan..... 2

2 (1’). Pronotum with white to cream­colored anterior and lateral borders uneven ( Figs. 3H, J–K View FIGURE 3 ): lateral border distinctly wider than anterior border; anterior border sometimes broken or obsolete, in some specimens with spurlike markings projecting posteriorly onto disk ( Fig.3L View FIGURE 3 ). ................................................................................. 3

2’. Pronotum with white to cream­colored border of uniform width ( Fig. 3I View FIGURE 3 ), or at most only slightly narrower anteriorly than laterally, without spurlike markings ............ 5

3 (2). Elytra with dark maculae framing a common pale teardrop­shaped mark or pair of such marks near suture at midlength ( Figs. 1A, B View FIGURE 1 ); body form shortened, oblong, strongly convex ( Figs 3A, B View FIGURE 3 ); antenna with 9, 10, or 11 antennomeres .................. 4

3’. Elytra with pair of discrete pale circular marks near suture at midlength ( Fig.2B View FIGURE 2 ); body form slightly elongate oval, moderately convex ( Figs. 2B View FIGURE 2 , 3F View FIGURE 3 ); antenna with 11 antennomeres ( Fig.9G View FIGURE 9 ). Bolivia, Argentina ( Fig 11 View FIGURE 11 , stars) ... C. sicardi (Brèthes)

4 (3). Elytra bicolored, or at least with orange to paler cream areas strongly suffused: common teardrop­shaped mark not divided at suture; dark maculae as shown ( Figs. 1A View FIGURE 1 , 4M–N View FIGURE 4 ). Northern Chile, northern Argentina, Bolivia ( Fig10 View FIGURE 10 , squares) .............. ..................................................................... C. lacrimosa González and Vandenberg

4’. Elytra distinctly tricolored: pale central elytral figure divided by ferrugineous suture to form pair of cream­colored teardrop­shaped marks, one on each elytron; dark maculae as shown ( Figs. 1B View FIGURE 1 , 4O–P View FIGURE 4 ). Known from disjunct localities in Chile, Argentina ( Fig. 10 View FIGURE 10 , circles with cross) ... C. disconsolata Vandenberg and González

5 (2’). Posterior third of each elytron with pale spot positioned near apex ( Figs. 4I–L View FIGURE 4 ) and often obliquely flattened against posterolateral margin (pale spot poorly distinguished from orangy ground color in most C. eryngii , Figs. 4A–H View FIGURE 4 ). Dorsal surfaces shiny; punctation sharply defined; surface between punctures with less apparent reticulation. Widespread in Chile and Argentina..................................... 6

5’. Posterior third of each elytron with circular to irregular pale spot centered some distance from apex ( Figs. 5I–K View FIGURE 5 ), but with outer edge approaching apex if spot is large ( Fig. 5I View FIGURE 5 ). Dorsal surfaces matt; punctation shallow and indistinct; surface between punctures with pronounced reticulation (alutaceous). Known from Bolivia and northern Argentina ( Fig. 11 View FIGURE 11 , circles with dot) ................. C. boliviana (Mulsant)

6 (5). Antenna with 11 antennomeres ( Fig 9F View FIGURE 9 ). Most specimens with dark elytral marks well separated at midline, less commonly with marks touching or longitudinally connected midway between sutural and median area of each elytron ( Figs. 4A–H View FIGURE 4 ); elytron in lateral view evenly convex and tapering toward apex, broader at anterior 1/4 than at posterior 1/4 ( Fig. 3E View FIGURE 3 ); in dorsal view, outer margin of elytron distinctly arcuate ( Figs. 2A View FIGURE 2 , 4A–H View FIGURE 4 ). Male genitalia with basal lobe slender, broadest at base ................................................................................................... C. eryngii (Mulsant)

6’. Antenna with 10 antennomeres ( Fig 9E View FIGURE 9 ). Most specimens with dark elytral marks connected by median longitudinal stripe ( Figs. 4J–K View FIGURE 4 ), some also with narrow parasutural and/or paralateral longitudinal connections, less commonly with median connection obsolete ( Fig. 4I, L View FIGURE 4 ) or indicated only in ground color; elytron in lateral view less convex in anterior half, less strongly tapered, equally broad at anterior and posterior 1/4 ( Fig. 3D View FIGURE 3 ); in dorsal view, outer margin of elytron linear to weakly arcuate for much of length ( Figs. 1D View FIGURE 1 , 4I–L View FIGURE 4 ). Male genitalia with basal lobe more robust than in preceding species, broadest at swollen region in apical ½.................. ...............................................................................................
