- Tergite 6 lacking row of such long posterior setae ( Figs. 17–21, 23 ).............................................. 2

2 Tergites plain brown, with small setae dorsally on tergite 6 ( Figs. 19, 21 ); North America............................. 3

- Tergites yellowish, with darker markings and usually larger setae on segment 6 ( Figs. 17, 18, 20, 23 ); Central and South Amer- ica................................................................................................. 4

3 Ventral sclerite of oviscape small, nearly round ( Fig. 13 ); sternite 6 laterally without setulae................................................................................................. Apocephalus missouriensis new species
