众所周知，蚂蚁在采集食物和移动巢穴时会利用踪迹信息素来招募巢友[2]。在Ponerinae亚科的几个物种中，毒腺已被确定为拖尾信息素的来源[3，4]。(3R，4S)-4-甲基-3-庚醇是首次报道的Ponerinae亚科拖尾信息素，它以单一物质的方式引发拖尾活动，而这种方式与细小细毛虫毒腺提取物几乎无法区分的方式[5]。最近我们发现，同样的化合物存在于该属另一物种的毒腺中。这一物种，我们称之为L.种5，在形态上与L.assamens相似(凭证标本可在哈佛大学比较动物学博物馆和伦敦自然历史博物馆获得)。事实上，L.物种5的工作人员跟踪了合成的4-甲基-3-庚醇(未公布的数据)。因此，不足为奇的是，细长斑潜蝇和5号斑潜蝇的工作人员能够追踪由这两个物种的毒腺提取物制成的人工足迹。然而，这一属的另一种，L.peuqueti，它对自己的毒腺提取物表现出跟踪反应，但没有追随L.minuta或L.种5的反应。
Ants are known to utilize trail pheromones to recruit nestmates during food gathering and nest movement [2]. In several species of the subfamily Ponerinae the poison gland has been identified as the source of the trail pheromone [3, 4].(3R, 4S)-4-Methyl-3-heptanol, the first reported ponerine trail pheromone, elicits as single substance trail-following activity in a manner virtually indistinguishable from that evoked by a poison gland extract of Leptogenys diminuta [5]. Recently we discovered that the same compound is present in the poison gland of another species of this genus. This species, which we call L. species 5, is morphologically similar to L. assamensis (voucher specimens are available at the Museum of Comparative Zoology, Harvard University, and Natural History Museum, London). In fact, workers of L. species 5 followed trails made of synthetic 4-methyl-3-heptanol (unpublished data). Therefore it is not surprising that L. diminuta and L. species 5 workers are able to follow artificial trails made of poison gland extracts of either species. However, another species of this genus, L. peuqueti, which showed trail-following responses to its own poison gland extracts failed to follow those of L. diminuta or L. species 5.
