We describe a pair of labial gland lobes on either side of the retrocerebral complex in the head of the Australian black field cricket, Teleogryllus commodus Walker. As the retrocerebral complex includes the corpora cardiaca and corpora allata, hormones secreted by these glands can be absorbed by these lobes. These lobes of the labial gland are connected to the thoracic lobes via a relatively long duct that enters the main duct draining the thoracic lobes. Measurement of the flow rate of dye from head to thorax in the ducts is rapid, suggesting that these glands may serve as a transport system into the thoracic region. Both serotonin and adipokinetic hormone are shown to be present in the lobes near the retrocerebral complex and the ducts of the thoracic lobes, but whether this connection between the head and thorax acts as a hormone transporter is still unclear.

黑场Cri（直翅目：Gryllidae）中的新型头胶囊唇唇腺叶。

我们在澳大利亚黑野Teleegryllus commodus头部的后脑复合体的两侧描述了一对唇腺叶沃克。由于脑后复合体包括cardiac体和异体，这些腺体分泌的激素可被这些叶吸收。唇腺的这些裂片通过相对较长的导管连接到胸廓，该导管进入排干胸廓的主导管。快速测量染料从头到导管在导管中的流速，这表明这些腺体可以作为进入胸腔区域的转运系统。血清素和脂肪代谢激素均显示在脑后复合体附近的叶和胸叶的导管中，但是尚不清楚头部和胸部之间的这种连接是否是激素转运体。
