Pedetontoides atlanticus Mendes, 1981

The distinctive males of this monospecific genus are easily recognized and separated from other southeastern United States machilid males due to the presence of parameres on both the eighth and ninth abdominal segments. Among the Nearctic Microcoryphia , this character is otherwise present only in the genus Meximachilis Wygodzinsky , represented in the United States by M. cokendolpheri Kaplin from New Mexico. In both males and females of P. atlanticus , the posterior angle of the fourth urosternite is acutely pointed, although it can approach a right angle, which is characteristic of Pedetontus species. Previously, this species was known only from the type series of 12 adults and 5 juveniles from Durham, North Carolina ( Mendes 1981a). These records add Alabama, Arkansas, Georgia, and Mississippi as new state records to the known distribution of this species.
