Cynipid galls of the eastern United States

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.
