Abstract
The tropharia of the dipsocoromorphan bugs, Cryptostemma alienum and C ryptostemma carpaticum (Heteroptera : Dipsocoridae) are composed of 30 -50 mononucleate nurse cells that are connected with centrally located trophic cores by means of broad cytoplasmic strands. The anteriormost nurse cells are markedly smaller and often reveal signs of degenerati on. The trophic core is surrounded and penetrated by elaborate F-actin meshwork. Arrested oocytes and prefollicular cells are localized at t he base of the tropharium. Anagenesis of heteropteran ovarioles is dis cussed in relation to the findings presented.
