Key to the Neotropical species of Sympagus Bates

1 Pronotum with a broad, dark, even­sided longitudinal median vitta, extending from head to elytral base; elytral pattern bold, clear, ornate, yellow and brown or whitish and brown; apical area of elytra with dark maculae on pale background ..................... 2

­ Pronotal coloration variable, dark areas on disk, if present, irregular in outline; elytral pattern ornate or diffuse, but always consisting of several different colors, apical onefourth variably marked, may be marked with white, gray or yellow, but without contrasting dark maculae .................................................................................................... 3

2(1)Dorsal pattern formed by bright yellow, dark brown and black appressed pubescence; outer angle of elytral apex strongly dentate. Southern Guatemala, Nicaragua, Costa Rica, Panama.................................................................................... S. laetabilis (Bates)

­ Dorsal pattern formed by ashy­white and dark brown appressed pubescence; outer angle of elytral apex obtusely angulate. Southern Mexico, northern Guatemala.......... ................................................................................................... S. cedrelis , new species

3(1)Dorsal elytral pattern boldly marked, consisting of pale pubescent vittae and bands on a darker background, or having distinct black maculae, margined posteriorly with yellow, on a red­brown background................................................................................... 4

­ Dorsal elytral pattern diffuse, consisting of vaguely defined or mottled pale areas on a dark brown, gray and black background, or the disk mostly dark gray­brown with basal area light brown, and with a pale band before apex............................................. 5

4(3)Pronotum thinly yellow pubescent across middle; elytra with well­defined black maculae on a red­brown background: a V­shaped sutural mark behind scutellum, and a broad, angulated, subtriangular lateral mark on middle one­half of elytra, dark markings narrowly margined with yellow pubescence. Bolivia............... S. buckleyi (Bates)

­ Pronotum pale with a longitudinal dark median area; elytra with pale “M”­shaped marking on basal one­half, broadly dark pubescent over post­median one­third, pale apically. Eastern Ecuador, Peru, Bolivia, French Guiana, Brazil (Amazonas, Pará, Rondônia, Mato Grosso) .......................................................... S. favorabilis Tippmann

5(3)Pronotum and basal portion of elytra brown, elytral disk dark gray­brown with large black macula on the epipleura, a pair of velvety black maculae behind middle, a small yellow macula at the upper margin of the epipleuar, and an irregular preapical pale yellowish band; posterior femora wholly piceous or dark reddish­brown. Panama...... .................................................................................................... S. monnei , new species

­ Pronotum and elytra mottled gray and brown, epipleura with a semi­circular black macula at basal one­third and an irregular pale fascia at middle, extending partially onto disk, apical two­thirds of disk with a vague transverse darker fascia, apical onefifth mottled with light gray; posterior femora piceous with base red­brown. Bolivia, NW Brazil (Amazonas), Ecuador, French Guiana................ S. bimaculatus (Gilmour)
