Genus Hentzia
Explanation of Names
Named in honor of Nicholas Marcellus Hentz.
Numbers
5 species in our region, the four described below by Jay Barnes and H. pima, known only from a single female specimen from southern Arizona (see Richman revision below).
Identification
"There are currently four Hentzia species recorded in eastern North America, north of Mexico. Outside of Florida and southern Georgia there are just two, H. palmarum and H. mitrata. The southern edge of Georgia adds H. grenada, which is found as far south as the Keys, and southern Florida picks up H. chekika, which can also be found in the Bahamas and Cuba.

Distinguishing the adult males of all four species doesn't appear to be too difficult. H. mitrata is a giveaway with its white front legs and overall light coloring. H.palmarum adds pigmented first legs, darker coloring and sometimes a thin dorsal marking on the rear half of the carapace. H. grenada is similar to palmarum, but the marking is somewhat broader and extends to cover the whole length of the carapace. H. chekika is similar to grenada, but the abdomen marking appears to be more sharply defined." - Jay Barnes
