description: Key to the genera of the tribe Priocnemini  Females   1. Anterior margin of propodeum arched and steeply elevated over deeper metapostnotum. Mesosoma (dorsal view) distinctly narrowed near posterior margin of mesoscutum. Wings reduced, narrowed and diminished to vestigial with reduced venation........................................................................................................................... Claveliocnemis Wolf   
– Anterior margin of propodeum straight or weakly arched and hardly elevated over shallow metapostnotum. Mesosoma not narrowed near posterior margin of mesoscutum. Wings always normal-sized........................................................................................................ 2  
 2. Clypeus enlarged, much wider than LID. Crossvein cu-a of hind wing originating at or distally to fork of vein M+Cu.......................................................................................... 3   
 – Clypeus normal-sized, narrower than LID. Crossvein cu-a of hind wing originating basally to fork of vein M+Cu...................................................................................................... 5   
 3. Apical margin of clypeus weakly produced medially.......................... Malloscelis Haupt   
– Apical margin of clypeus distinctly produced medially and laterally............................. 4  
 4. Metatarsal claw with one additional tooth. Clypeus with depressed rim lateroapically. Mandible with one additional tooth.................................................... Priocnessus Banks   
 – Metatarsal claw with two or three additional teeth. Clypeus without depressed rim lateroapically. Mandible usually with two additional teeth............... Platydialepis Haupt   
 5. Pronotum distinctly shortened, with well differentiated anterior vertical smooth face. Crossvein cu-a of fore wing originating at or weakly distally to fork M+Cu. Protibia dorso-apically with single very stout curved spine............................... Caliadurgus Pate   
 – Pronotum normal-sized, without well differentiated vertical and smooth anterior face. Crossvein cu-a of fore wing originating distinctly distally to fork M+Cu. Protibia dorsoapically without single stout curved spine....................................................................... 6
