Neuroterus weldi Melika and Abrahamson, NEW SPECIES
Comments.-Weld (1959) wrote of a stem swelling found on Q. chapmanii, but he never reared the adults and consequently did not describe the species. The galls induced by N. weldi are probably those Weld described.
Distribution.-Central and coastal sand ridges of south central Florida (Archbold Biological Station, Lake Placid, Highlands Co.; Avon Park Air Force Range, Highlands Co.; Jonathan Dickinson State Park, Martin Co.).
Biology.-Only the unisexual generation is known. The gall is cylindrical, mostly a terminal stem swelling, covered with normal bark, on second year or older twigs and branches only of Quercus chapmanii. It is 25.0-40.0 mm long, 6.0-9.0 mm in diameter, and polythalamous. Galls are not woody, rather they are easily cut like cheese. The leaf petioles are never involved in gall formation. Galls persist on stems for several years. Fully developed adults over- winter in galls and emerge from the second half of February into March of the following spring. The first galls observed are formed by the end of May.
