雄性蚂蚁的生殖器是在广义的水翅目的背景下解释的。首次建立了Amblyoponinae、Cerapachyinae、Dolichoderinae、Ecitoninae、Ectatomminae、Formicinae、Leptanilloidinae、Myrmicinae和Ponerinae 9个亚科26种蚂蚁的肌肉同源性。在雄性蚂蚁的外生殖器中总共发现了15块肌肉，并且所有这些肌肉都与基部Hyplitera的肌肉系统同源（Schulmeister 2001）。肌肉的继发性融合、减少或丧失发生在不同的谱系中。从广义到派生，描述和比较了三个分类群，Formica obscuripes Forel 1886，Messor andrei Mayr（1886）和Labidus coecus Latreille（1802）的功能形态和质量机制。特别提到了Ecitoninae，Birket-Smith（1981）的工作被重新解释，并阐明了volsellar同源性。真正的上唇指被发现是一个小片在远端volsellar元件的基础上，这是重新确定为尖。
The genitalia of male ants are interpreted in the context of the broader Hymenoptera. For the first time muscle homologies are established for twenty six species of ants in nine subfamilies: Amblyoponinae, Cerapachyinae, Dolichoderinae, Ecitoninae, Ectatomminae, Formicinae, Leptanilloidinae, Myrmicinae and Ponerinae. Fifteen muscles in total are found in the external genitalia of male ants and all are homologous with the musculature of basal Hymenoptera (Schulmeister 2001). Secondary fusion, reduction or losses of muscles have occurred in different lineages. From generalized to derived, the functional morphology and qualitative mechanics of three taxa, Formica obscuripes Forel 1886, Messor andrei Mayr (1886) and Labidus coecus Latreille (1802) are described and compared. Special reference is made to the Ecitoninae, where the work of Birket-Smith (1981) is reinterpreted and volsellar homology is clarified. The true digitus of Labidus is revealed to be a small sclerite at the base of the distal volsellar element which is re-identified as the cuspis.
