We collected a queenright colony of the very rare Myopias conicara Xu in Vietnam (1 dealate queen, 41 workers and 38 larvae). Both the queen and workers fed on xystodesmid millipedes. After paralyzing a millipede, its head was first removed by the workers, and then the larvae were put on the opening of the collum (anteriormost ring of the trunk). After the inner tissue of the collum was consumed, the exoskeleton of the collum was discarded. The feeding sequence was then repeated on the following rings of the trunk, until the entire prey was consumed. The ring‐shaped exoskeletons of the prey were deposited next to the nest entrance. The exocrine system of the workers (excluding the legs) contains 15 glands of which the structural features are similar to these of other ponerine ants. The presence of an oblong plate gland is interesting, as this gland had only been found previously in Myopias hollandi (Forel). However, none of the novel thoracic glands that were recently described in M. hollandi occur in M. conicara, which illustrates the variation within the genus Myopias. A unique characteristic of the class‐3 glands of Myopias ants is the gradual widening of the ducts, which has never been found in other insects, although the functional significance remains unknown.

小马蚁 Myopias conicara Xu, 1998 (Hymenoptera: Formicidae) 中的群体组成、蜂后行为、对千足虫的专门捕食和外分泌腺

我们在越南收集了非常稀有的 Myopias conicara Xu 的蚁后群落（1 只蚁后、41 只工蚁和 38 只幼虫）。女王和工蚁都以 xystodesmid 千足虫为食。麻痹千足虫后，工人们首先将其头部取下，然后将幼虫放在颈口（躯干最前环）处。颈椎的内部组织被消耗掉后，颈椎的外骨骼被丢弃。然后在树干的以下环上重复喂食顺序，直到吃掉整个猎物。猎物的环状外骨骼沉积在巢穴入口附近。工蚁的外分泌系统（不包括腿）包含 15 个腺体，其结构特征与其他小马蚁相似。长方形板腺的存在很有趣，因为这个腺体以前只在 Myopias hollandi (Forel) 中发现过。然而，最近在 M. hollandi 中描述的新胸腺都没有出现在 M. conicara 中，这说明了近视属内的变异。近视蚂蚁 3 类腺体的一个独特特征是导管逐渐变宽，这在其他昆虫中从未发现过，尽管其功能意义仍然未知。
