About Witica crassicauda (Keyserling, 1865)
Witica crassicauda (Keyserling, 1865) shows notable size difference between sexes, with females being considerably larger than males. Females have a total body length of 6.5 to 12.0 mm; males range between 1.4 and 1.7 mm in total length. For the carapace, females measure 3.2 mm long by 2.7 mm wide, while males have a carapace that is 0.9 mm long and 0.7 mm wide. This species can be identified by several distinct diagnostic traits. In females, the median septum of the epigyne is at least as wide as the depressions located on either side of it. In males, a distinctive curved tube sits at the base of the embolus tip. For female individuals, the dorsal coloration, pattern, and shape of the abdomen are variable characteristics within the species. Witica crassicauda has been recorded in forests across Central and South America. Its range extends from Mexico, through Central America, to Venezuela and Peru, and also includes the Greater Antilles. Confirmed specific localities include multiple sites across Mexico, Guatemala, Honduras, Nicaragua, Costa Rica, Panama, Cuba, the Dominican Republic, Puerto Rico, Trinidad, Venezuela, Colombia, and Peru. Across its entire range, the species lives in forest habitats.
