工蚁有微小的胸膜附属物，称为“双胞体”，它们代表了蚁科中独特的腺体结构。在australe中，每个gemma含有大约。500个腺体细胞通过细胞质外表面细小的孔连接在一起。一种特殊的末端装置形成两种细胞类型之间的连接处。分泌细胞的超微结构检查显示有光滑的和颗粒状的内质网，有电子透明的和电子致密的包涵体。因此，分泌物可能具有相当复杂的成分。它的功能可能与在这只无蚁后的蚂蚁身上发现的特殊的生殖调节机制有关。
SUMMARY Workers of Diacamma have minute mesothoracic appendages termed « gemmae», and these represent a unique glandular structure among the Formicidae. In D. australe, each gemma contains approx. 500 glandular cells which are individually connected by duct cells opening through minute pores on the outer surface of the gemma. A specialized end apparatus forms the junction between the two cell types. Ultrastructural examination of the secretory cells shows the presence of both smooth and granular endoplasmic reticulum, and the occurrence of both electron-lucid and electron-dense inclusions. The secretion may there fore have a rather complex composition. lts function is presumably related to the pecuLiar mechanism of reproductive regulation found in this queenless ant.
