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).
