Key to species of Pseudolechriops

1. Posterior tibiae flattened and weakly arcuate on posterior margin; from above rhom-

boidal in shape with elytra conspicuously wider than base of pronotum .................... 2 1’. Posterior tibiae slender, subcylindrical, not conspicuously flattened; from above usually slender, subcylindrical, with elytra not conspicuously wider than base of pronotum................................................................................................................................. 7

2. Sides of pronotum with broad oblique band of dense white setae from sides of rostral canal to dorsal posterior angles (upper portion lacking in males); elytra partly or entirely dark reddish-brown with conspicuous medial sutural spot of yellowish setae; rostra of males and females similar in shape; Costa Rica, Panamá................................ ...............................................................................................6. P. klopferi , new species

2’. Sides of pronotum more or less sparsely covered with setae, in some cases forming indistinct narrow white lateral stripe; elytra entirely black with various patterns of white setae; rostra of males and females strongly sexually dimorphic in shape .......... 3

3. Disc of pronotum appearing black, with sparse, inconspicuous white or pale yellowish setae notforming a distinct pattern; elytra with distinct pattern of white setae, but not with medial sutural chevron .......................................................................................... 4

3.’ Disc of pronotum with conspicuous pattern of dark yellowish setae; elytra with small transverse chevron of white setae across suture beyond the middle............................. 5

4. Elytra with transverse basal fascia of white setae and oblique fascia from the suture at middle to the lateral margins; femora black; Guatemala to South America................... .......................................................................................... 1. P. megacephala Champion

4.’ Elytra with transverse basal fascia of white setae connecting along suture to elongate spot of white setae at middle; femora reddish brown; posterior tibiae black; Costa Rica.............................................................................................. 2. P. longinoi , new species

5. Elytra with conspicuous basal transverse fascia of white setae; rostrum of both sexes red, that of male extravagantly modified ( Fig. 3 ), densely covered with white setae; México, Guatemala............................................................ 3. P. dimorpha , new species

5’. Elytra with inconspicuous basal transverse fascia of white and pale yellow setae; rostrum of both sexes all or mostly black, that of male less extravagantly modified, glabrous and polished; Nicaragua or Costa Rica to Panamá.............................................. 6

6. Anterior and middle femora almost entirely red; rostrum entirely black; Nicaragua to Panamá......................................................................... 4. P. howdenorum , new species

6’. Anterior and middle femora black on basal 1/3–1/2; rostrum black on basal 2/3–3/4, tip red; Costa Rica, Panamá........................................... 5. P. davidsonae , new species

7. Elytra completely black with more or less conspicuous and well-defined transverse white fascia at base........................................................................................................ 8

7’ Elytra reddish brown or reddish brown and black, with or without transverse white fascia at base, if with basal fascia, then also with medial sutural spot .............................. 9

8. Elytra with poorly-defined basal fascia connected along suture to medial sutural spot; setae on sides of pronotum sparse, irregularly distributed over most of surface ............ ................................................................................................. 8. P. a l l e n i, new species

8’. Elytra with sharply-defined basal fascia only and no sutural spot; setae on sides of pronotum denser, forming a relatively well-defined oblique white stripe from base of eyes to anterior to elytral humeri........................................ 9. P. wrightae , new species

9. Elytra with transverse white fascia at base; male with eyes more widely separated, densely white setose at base of rostrum above antennal insertions................................. ................................................................................................ 7. P. janeae , new species

9’. Elytra without basal fascia; male with eyes narrowly separated, glabrous above antennal insertions ....................................................................... 10. P. c o l e y a e, new species
