Diagnosis

Lacronia ricardoi can be differentiated from the other species of the genus by the following combination of characters: 1) mesotergum areas I–II with pale-colored stripes contrasting the background, forming a divided triangular spot ( Figs 4C , 15A ); 2) mesotergum areas I–IV without conspicuous tubercles ( Figs 4C , 15A ); 3) cheliceral bulla proximal border unarmed ( Fig. 15A ); 4) Tr IV with a prolateral proximal hook-shaped apophysis ( Fig. 15A–B ); 5) Mt IV dorsal face with a row of subconical tubercles on the proximal half and subconical spines on the distal half ( Kury 2003b: fig. 10); 6) stem of the stylus covered by tiny spines on the ventral face ( Kury 2003b: fig. 14); 7) subapical portion of the stylus swollen ( Kury 2003b: fig. 14); 8) ventral process of the glans with lateral rows of spines ( Kury 2003b: figs 13–14).
