Diagnosis: <\/strong>Caplothorax sayi<\/em> specimens are distinguished from other eastern North American species by having the following combination of features: length measured from mandibles to abdominal apex 4.3-5.1 mm, antennomere coloration abruptly or gradually darker towards the club, and the pronotum posterior angles broadly rounded with no distinct ‘corner’ created. Males also have a pair of elongate oval depressions lateral and anterior to the supplementary segment on the 5th ventrite (Fig. 5). Females also have a weak median longitudinal ridge on the pygidium (Fig. 7 & 8) and grooves along the lateral margins of the pygidium (Fig. 7).<\/p>\n

Distribution: <\/strong>Caplothorax sayi <\/em>is found in eastern North America from Nova Scotia to Georgia and west from Saskatchewan to Texas and New Mexico.<\/p>\n

Biology: <\/strong>C. sayi<\/em> is primarily associated with wounds on hardwood trees (Connell, 1956). It is one of the primary nitidulid vectors of the oak wilt pathogen Ceratocystis fagacearum<\/em> in Minnesota, transporting spores from oak wilt mats to fresh wounds on uninfected trees (Juzwick, Skalbeck, and Neuman, 2004). C. sayi<\/em> has also been collected in traps baited with banana, fermenting brown sugar and bread dough, and cantaloupe (Price and Young, 2006).<\/p>\n
