description: Key to adults of described Neotropical (including Chile) genera of Eurypinae
1 Head with distinct, shallowly impressed ocular grooves, narrowly separated from eyes, traceable from frontal canthus to poste- rior extent of eye...................................................................................... 2
- Head without such an ocular groove....................................................................... 3
2 Procoxal cavities closed; dorsal surface without conspicuous setae; elytral shape generally conical, widest posteriorly (Fig. 21)..................................................................... Stilpnonotus Gray (7 described species)
- Procoxal cavities narrowly open; dorsal surface with conspicuous setae (although short in some species); elytral shape gener- ally parallel-sided (Fig. 22)........................................ Conomorphus Champion (10 described species)
3 Eye with conspicuous intrafacetal setae (e.g., Fig. 32)......................................................... 4
- Eye either without intrafacetal setae, or setae so short they are not noticeable using standard light microscopy, definitely not conspicuous.......................................................................................... 8
4. Head with distinct, deep frontal furrows (e.g., Figs 32–33)..................................................... 5
- Head without deep frontal furrows........................................................................ 7
5 Mandibles bluntly unidentate apically; eyes small, widely separated (ocular index> 60); antennomeres elongate, filiform to subserrate; dorsal body surface with light and dark setae, producing a mottled appearance (Fig. 23)........................................................................................... Loboglossa Solier (6 described species)1
- Mandibles bidentate apically; eyes larger, more narrowly separated (ocular index <60); antennomeres variable; dorsal body surface either uniform in color, or with longitudinally oriented color pattern, not mottled............................ 6
6 Penultimate tarsomere very wide, wider than length of distal tarsomere (Fig. 32); frontal furrows relatively straight, subparallel; ommatidia coarse.............................................. Eurypus Kirby (6 described species) (Fig. 24)
- Penultimate tarsomere wide, but width less than length of distal tarsomere; frontal furrows somewhat arcuate, distinctly convergent anteriorly (Fig. 33); ommatidia fine...................... Cladobradus Pic (1 species: C. atritarsis Pic) (Fig. 25)
7 Male sex patch consisting of setae on both ventrites 2 and 3; wing rudimentary, not extended to elytral apex................................................................ Conomorphinus Champion (1 species: C. bolivianus Champion)
- Male sex patch restricted to V2; wing fully developed, extended to elytral apex.................................... 8
8 Male sex patch consisting of distinctly raised, rounded “platform” with either no setae, or setae short and dense; known only from Chile............................................. Batobius Fairmaire & Germain (4 described spp.) (Fig. 27)
- Male sex patch consisting of relatively long setae, borne on raised medial section of ventrite 2; Known only from Brazil............................. Brasilaccoderus Pollock (2 species: B. scaber (Champion) and B. plaumanni Pollock) (Fig. 26)
9 Head distinctly rounded; eyes large, width across eyes equal to or greater than width of pronotum; pronotum with lateral carina present, at least in basal half; male sex patch on V3. ......................................................... 10
- Head not distinctly rounded; eyes usually smaller, width across eyes less than or equal to width of pronotum; pronotum with lateral carina absent, or at most vaguely suggested only, in basal half; male sex patch on V2. ........................ 11
10 TL of most specimens> 3.5 mm; apical maxillary palpomere cultriform; apical labial palpomere ovate with truncate apex........................................... Cleodaeus Champion (1 described species: C. rugiceps Champion) (Fig. 30)
- TL of most specimens <3.5 mm; apical maxillary palpomere securiform; apical labial palpomere narrowed distally, pyriform........................................................... Physcius Champion (22 described species) (Fig. 31)
11 Eyes flat and not protuberant, facets coarse, width of single eye about half length; frontal furrows absent; male sex patch absent........................................................ Thisias Champion (5 described species) (Fig. 28)
- Eyes more protuberant, facets fine, width of single eye distinctly greater than half length; frontal furrows at least suggested, often rather deep; male sex patch present, on ventrite 2....................................................... 12
12 Head with frons slightly to distinctly sunken about level of antennal insertions; pronotal disc with pair of distinct, rounded depressions................................................... Physiomorphus Pic (8 described species) (Fig. 29)
- Head with frons flat, not sunken; pronotal disc uniformly convex, without pair of distinct, rounded depressions (in some specimens – notably T. brasiliensis – with slight indentations, but not distinct, rounded depressions).................................................................................................... Thisiomorphus Pic (Figs 1–12)
