title: [Observation on a new sensillum of cerci of Periplaneta americana by scanning electron microscopy].
abstract: This paper deals with the morphology of the cerci of Periplaneta americana under the scanning electron microscope. In this initial study a new sensillum on the ventral surface of cercus segments is found and described in detail. This sensillum has an upside-down disc-shaped base with a central slender spear-shaped receptor hair, hence the authors named it "speared sensillum".
