Diagnosis. The combination of metafemoral armature ( Fig. 5 a) and convoluted, foliate cercus ( Figs. 20 b, 21b) will distinguish males from all others except for L. guanacaste . The proximal large metafemoral spur of L. candelaria ( Fig. 5 a) is not as long as that of L. guanacaste ( Fig. 5 b) and the shape of the cerci differ between the two species. The ventro-basal process in L. candelaria is projected ventro-posteriorly and is visible in medio-dorsal view when the cerci are spread ( Fig. 20 b); this structure is ventrally curved and hidden from view when the cercus is viewed medio-dorsally in L. guanacaste ( Fig. 20 c). Females of L. candelaria and L. guanacaste are unique in having the dorsal margin of ovipositor concave in lateral view ( Figs. 19 a, b); this structure is linear in all other species ( Figs. 19 c–f). The female of L. candelaria differs by the unique morphology of its prothoracic hind lobe; its middle lobe is expanded with lateral margins angulate and overlying a smaller inferior margin ( Fig. 2 b). In L. guanacaste , the hind lobe is upright, of even width, and its lateral arms are deflexed ventrally diverging from the carinate propleural extension ( Fig. 2 c). Mature individuals of L. candelaria have broad mid-dorsal and humeral dark stripes and the pale postocular spots are round ( Fig. 1 a); in mature L. guanacaste , the dark antehumeral stripe is lacking and the postocular spots are represented by narrow pale triangles ( Fig. 1 b).

Dimensions. Males (n = 2): Hw 15.0–15.6; abdomen 28; total length 33–34. Females (n 2): Hw 17.2– 18.1; abdomen 26–28; total length 32–33.

Distribution. Cuba, Mexico, and Belize ( Fig. 27 ).
