Type locality. "…une mare à Brouillard, près de Port-au-Prince", Haiti.

Type material. Lost—absent in the Richard's collection ( Kotov & Ferrari 2010).

Studied material. 4 parthenogenetic females from Pond near road in Los Hoyos town. El Llano, Aguascalientes, 21.09.1991, AYS; 16 parthenogenetic females from Pond near road to La Colorada town. El Llano, Aguascalientes. 12.09.1992, AYS; 1 parthenogenetic female from Pool in El Huarache farm, Calvillo, Aguascalientes, 26.06.1987, AYS.

Comments. Morphology of the studied specimens ( Fig. 11 E–H) completely agrees with the recent redescription of the species ( Sinev et al. 2005). Closely related species, L. chihuahuensis Elías-Gutiérrez & Valdez- Moreno, 2008, was recently described from Chihuahua desert of Mexico, it appears to be a local endemic of the latter. For differences between these species, see Elias-Gutiérrez & Valdez-Moreno (2008).

Distribution. L. davidi is widely distributed in the Neotropics, but is never recorded in the mountainous areas. In Aguascalientes, L. davidi is found mainly in the dry, low altitude region, with xerophytic vegetation (mainly Cactacea and Leguminosae), where the summer temperatures are high.
