Prefemoral part ( prf) ca 2 × as long as broad. Prefemoral process ( prp) closely appressed to and distally curving over solenomere. Solenomere ( slm) long, slender, taeniate, pointed. Parasolenomere ( ps) much shorter than solenomere, thin, straight, pointed, with small needlelike side branch ( nb) basally.
