We followed standard procedures for preparation and
study of female and male genitalia (MORAES & DUARTE 2009).
The abdomen was carefully removed from each specimen and
soaked in 10% KOH for approximately 18 hours, being cleaned
with a soft brush and opened by one side to remove the genitalia.
Drawings were made with aid of camera lucida, and digitally
edited with Adobe Illustrator© CS3.
