本文报道了鲍氏斑节蜱ParandaniaBoecki（斯泰宾，1888）的消化道。对肠道内容物的检查表明，该物种以刺胞藻为食。食道、胃和中肠适于摄取和储存大量的软质食物。食道的开口由唇盖和胃入口处的“双闸门”状双翅关闭。前肠极度扩大，漏斗区域缩小。中肠很可能与前肠不相连，食物的再吸收只发生在中肠盲囊。中肠在中肠盲囊上方形成一个浅的新月形腔。
The alimentary canal ofParandania boecki(Stebbing, 1888) has been investigated. Examination of gut contents shows that this species feeds on Cnidaria. The oesophagus, stomach and midgut are adapted to ingest and store large masses of soft food. The opening of the oesophagus is closed by a labral operculum and ‘double gate’ — like narrowings at the stomach entrance. The foregut is extremely enlarged and the funnel region is reduced. The midgut very probably is not connected to the foregut, and the resorption of food takes place only in the midgut caeca. The midgut forms a shallow, crescentic cavity over the midgut caeca.
