Abstract
The spermathecae of eleven genera of the family Dinidoridae (Dinidorinae and Megymeninae) were studied. Four types of spermatheca morphology were observed. Possible use of the morphology of spermathecae in the taxonomy of Dinidoridae is discussed.
Highlights
The spermatheca is an accessory female reproductive organ which, occurs in all orders of insects except for Protura and Collembola (Matsuda, 1976)
This study examines the morphology of the sper matheca in Dinidoridae and establishes their taxo nomic importance
The results of our study show that there is no uniform type of spermatheca in the Dinidoridae
Summary
The spermatheca is an accessory female reproductive organ which, occurs in all orders of insects except for Protura and Collembola (Matsuda, 1976). It is a complex organ and varies greatly in shape and histology between groups (Pendergrast, 1957). The sper matheca is present in all Pentatomoidea and usually con sists of a spermathecal duct, leading from the vagina to a dilated spermathecal bulb, and is characterised by a well marked pumping region with proximal and distal flanges (McDonald, 1966). The spermathecal bulb is covered by secretory cells located outside the epithelium of the sper matheca. The spermatheca plays a significant role in many functions e.g.: sperm storage, copulation, fertiliza tion, oviposition (Gaffour-Bensebban, 1991, 1994)
