Key to the Chilean species of Baeocera 1 Elytra with sutural striae shortened, starting posterior level of scutellar tip ........................2 - Elytra with sutural striae not shortened, starting at elytral bases.........................................8 2 Pronotum with dark transverse fascia, elytra each with dark spot covering middle part of disc. Tip of median lobe obtuse ........................................................... S. stewarti nov.sp. - Colour pattern different. Tip of median lobe acute (aedeagus unknown in B. valdiviana ) .........................................................................................................................3 3 Antennae conspicuously short, antennomeres VIII about 1.3 times longer than wide, XI about 1.7 times longer than wide.

B. villaricensis nov.sp. - Antennae not conspicuously short, antennomeres VIII at least 1.5 times as long as wide, XI usually about two times as long as wide. Elytra ochraceous to blackish, often lighter apically, not reddish .................................................................................................4 4 Elytra strongly narrowed apically, with sutural striae starting posterior basal third of sutural length. Metanepisterna completely fused with metaventrite ..................................... ............................................................................................................ B.burckhardi nov.sp. - Elytra almost parallel or weakly narrowed posterior widest point, sutural striae starting in basal third of sutural length. Metanepisterna separated from metaventrite by deep suture...................................................................................................................................5 5 Metaventrite darker than elytra and pronotum, with apicomedian patches of distinct setiferous punctures; exposed metanepisterna narrow, about 0.02-0.03 mm wide. Internal sac of aedeagus with very long and narrow flagellum ............. B. nonguensis LÖBL - Metaventrite not darker than dorsum of body; exposed metanepisterna usually at least 0.04 mm wide......................................................................................................................6 6 Antennomeres VIII less than two times as long as wide. Ventrite 1 microsculptured. Metaventrite without patch of distinct setiferous punctures. Apical section of parameres slightly widened, short ......................................................................... B. chilensis REITTER Antennomeres VIII at least two times as long as wide. Ventrite 1 not microsculptured ....7 7 Pronotum and elytra, apical part of latter excepted, uniformly reddish to blackish. Antennomeres VIII almost as long as antennomeres VII ........................ B. cekalovici LÖBL - Pronotum and elytra along bases and elytra along sutural striae lighter than pronotal or elytra disc. Antennomeres VIII much shorter than antennomeres VII ........... B. valdiviana LÖBL 8 Sutural striae of elytra starting at base, near margin of pronotal lobe, not curved along basal margins, not forming basal striae ...............................................................................9 - Sutural striae of elytra curved along pronotal lobe and extended laterally to form basal striae..................................................................................................................................10 9 Body length 1.3-1.6 mm . Metaventrite without impressions and lacking patch of distinct setiferous punctures ......................................................................... B. germaini PIC - Body length 1.8 mm . Metaventrite with apicomedian impressions and patches of distinct punctures ............................................................................................. Baeocera sp. 10 Basal striae of elytra entire, joined to lateral striae................................... B. darwini nov.sp. - Basal striae of elytra incomplete, extended laterad about to mid-width of elytral base, not joined to lateral striae ..................................................................................................11 11 Elytra light, with dark spot in middle. Submesocoxal areas small, shorter than third of shortest interval between them and metacoxae. Internal sac with long, very narrow flagellum ......................................................................................... B. variicolorata nov.sp. - Elytra not spotted. Submesocoxal areas as long as or longer than shortest interval between them and metacoxae............................................................................................12 12 Pronotum and elytra uniformly light or pronotum slightly darker than elytra. Antennomeres VIII and XI each well three times as long as wide. Aedeagus with long, looped flagellum..................................................................................... B. jarmilae nov.sp. - Pronotum much darker than elytra. Antennomeres VIII and XI each somewhat more than two times as long as wide. Aedeagus lacking long flagellum............... B. atricollis PIC
