摘要

The ultrastructure of the spermatozoa of seven species of Proceratophrys and one of Odontophrynus was analyzed in the present study. The sperm of Odontophrynus juquinha is similar to that of Odontophrynus cultripes, previously described, and to those of Proceratophrys branti, Proceratophrys bigibbosa, Proceratophrys affin is concavitympanum, Proceratophrys huntingtoni, Proceratophrys conform is moratoi, P. moratoi, and Proceratophrys palustris, in relation to the acrosomal vesicle and the subacrosomal cone that covers the anterior region of the nucleus in the sperm head. We observed transverse striations in the midpiece of the Odontophrynus juquinha sperm, a feature not observed in any Proceratophrys species. The sperm tail of all the studied species had a simple flagella and single axoneme associated with auxiliary structures (juxta-axonemal + undulating membrane + axial fiber). However, the juxta-axonemal fiber is thicker and the undulating membrane is shorter in Proceratophrys in comparison with Odontophrynus. In addition to differentiating these two genera, these features represent a possible autapomorphy in Proceratophrys.

Morato，和Proceratophrys Palustris，与覆盖精子头中核的​​前部区域的仿体膜囊泡和亚脉囊剂。我们观察到Odontophrynus juquinha精子中的中间膜中的横向纹条件，在任何ProCeratophrys种类中未观察到的特征。所有研究的物种的精子尾部有一个简单的鞭毛和与辅助结构相关的单一轴突（Juxta-Axonemal +起伏膜+轴向纤维）。然而，与Odontophrynus相比，Juxta-Axonemal纤维更厚，并且起伏的膜较短。除了区分这两种属之外，这些特征还代表了ProcerAtophrys中可能的自身形式。
