Fig. 7 Diagnosis. Differs from males of Miturgopelma kinchega sp. nov. in the short, not trianguloid vRTA and the ridge like median apophysis making it appear truncate in ventral view ( Fig. 7a ). Female unknown. FIGURE 7 . Miturgopelma archeri sp. nov. , male holotype, QM S77092, palpal bulb, cymbium and tibia: a , ventral view; b , c , median apophysis, two slightly different retrolateral views; d , RTA, dorsal view; e , habitus, dorsal view. Etymology. The species epithet is a patronym in honour of Professor Michael Archer, who, while at the Queensland Museum, recognised the significance of the Riversleigh fossil site, the type locality. Type material. Queensland : male holotype , Riversleigh , site D, lagoon, 18°52’12.108”S 139°05’17.88”E , 123 m , 10 Jul–24 Sep 2006 , R . Raven, B . Baehr, A . Amey, Pitfall Trap , QM S77092 .
