Sperm storage in cloacal spermathecae was determined in female Neurergus kaiseri salamander during the breeding season. Individuals stored sperm within spermathecal ultrastuctures. The spermathecae exhibited characteristics of secretory epithelium with irregular nuclei surrounded by thin cytoplasm and without organelles involved in synthetic activities. Within spermathecal tubules filled with secretory material, relatively small groups of sperm are aligned along their entire lengths in parallel arrays. Some spermatozoa are embedded in the secretory matrix or invaded deeper into the spermathecal epithelium. Considering the onset of courtship behavior in early December, and oviposition of first eggs in late February, we propose that sperm storage in N. kaiseri lasts 1.5-2 months.
