Neuroterus chapmanii Melika and Abrahamson, NEW SPECIES
Distribution.-Florida (Archbold Biological Station, Lake Placid, Highlands Co.; Jonathan Dickinson State Park, Martin Co.).
Biology.-Only the bisexual generation is known. Galls are on catkins of Quercus chapmanii, are ovoid, thin walled, up to 1.5 mm long, and with a groove running from one side to the other across the upper surface thus resembling a closed purse. The gall is covered with white pubescence, especially on the top, and is monothalamous. Galls are randomly scattered along the staminate axis and perpendicular to it. Sometimes two galls develop together. The galls are surrounded by anthers. As the gall and catkins mature, the color changes from green to pale brown. They remain on the catkins until emergence of the adult or longer, dropping along with the catkins. In Florida, on the Lake Wales Ridge, Chapman oak begins to flower the end of February to early March. We found the gall for the first time on 3 March 1995 when some of the galls had emergence holes, likely made by the gall-inducing wasps; also, pupae and adult wasps were cut from the galls on this date.
