Title:

This 2006 scanning electron micrograph (SEM), under a low magnification of only 76x, revealed the distal tip of the abdominal region of a fe

Description:

This 2006 scanning electron micrograph (SEM), under a low magnification of only 76x, revealed the distal tip of the abdominal region of a female body louse, Pediculus humanus var. corporis from a dorsal perspective. Some of the morphologic characteristics seen in this image include the two 'gonopodia', which are located dorsal to the larger two setae-bearing 'claspers'. It is into this notch that the male would insert the 'aedeagus', or penis during the process of copulation. This notch, identifying the louse as a female is observable to the naked eye, whereas, in the male louse, the distal abdomen is rounded, and not concave.
