Joadis Mews & Sperber gen. nov. et sp. nov.

Type species: Joadis mesai Mews & Sperber sp. nov.

Metanotal gland present. Tibia III with four internal dorsal spurs and four external, similar in size. Three large internal apical spurs: the first two time smaller than third, and three small external apical spurs: first and third smaller than second. Male terminalia with phallic glands; pseudepiphallic arms parallel, straight, not jagged ( Fig. 8 A); pseudepiphallic paramere 2 not jagged ( Fig. 8 A, B); pseudepiphallic paramere 1 draped in ventral view ( Fig. 8 B); ectophallic fold localized in the base of paramere ( Fig. 8 A); rami short ( Fig. 8 A, C); female copulatory papilla sclerotized, long and narrow ( Fig. 9 A, B), dorso-ventrally flattened ( Fig. 9 C), anterior portion rugged and posterior portion smooth ( Fig. 9 A-C).
