Genus JORDANTHRIBUS Zimmerman, 1938

KEY TO THE SPECIES

HMales 2 Females.................................................................................................................................... 3

2(1). Side margins of the rostrum continuously concave between the middle and apical expansion and not at all expanded at the apical third of the distance between the top of the head and mandibles and with the margin not elevated; antennae with the third segment simple and without an apical prolongation........................................................................ }. planifacietus Zimmerman.

Side margins of the rostrum very conspicuously elevated into a flange at one third of the distance between the top of the head and base of mandibles, the flange making a lateral expansion that is almost as broad as the apical part; third antenna! segment with a conspicuous terminal hooklike ventral prolongation about one third as long as the third segment...................................... TODO TODO TODO

3(1). Front of head and rostrum obviously slightly convex from side to side; sides of rostrum not sharply separated from dorsum; pygidium one third broader than!ong.............................................................. J. planifacietus Zimmerman.

Front of head and rostrum broadly and conspicuously flattened, not at all transversely convex; sides of rostrum shallowly concave and sharply separated from the dorsum by a rather vague dorso-lateral carina; pygidium but slightly broader than long................................ J. conspersus Zimmerman.

Only these two species of the genus are known; J. planifacietus is the genotype.
