Diagnosis

Lacronia camboriu can be differentiated from the other species of the genus by the following combination of characters: 1) mesotergum areas I–IV without conspicuous tubercles, except for the paramedian pair on area I ( Figs 4B , 10A ); 2) mesotergum areas I–IV with yellow-colored stripes contrasting the background, with central longitudinal narrow stripes on areas I and III, an ellipse on central area II and a pair of large patches covering all the area IV ( Figs 4B , 10A ); 3) cheliceral bulla unarmed on its proximal border ( Kury 2003b: fig. 15); 4) Ti III retro-ventral face with a row of three spines (III) on the distal third ( Kury 2003b: fig. 25); 5) Tr IV prolateral proximal portion with a hook-shaped apophysis ( Kury 2003b: fig. 15); 6) Mt IV with a dorsal row of outstanding conical spines (larger than the Mt IV diameter) ( Kury 2003b: fig. 24); 7) subapical portion of the stylus covered by tiny spines on the dorsal face ( Kury 2003b: fig. 28); 8) subapical portion of the stylus swollen ( Kury 2003b: fig. 28); 9) flabellum of the ventral process scallop-shaped, not bent ventrad ( Kury 2003b: fig. 28)
