First record of Ereymatermes rotundiceps (Termitidae: Nasutitermitinae) as inquiline of Embiratermes neotenicus (Termitidae: Syntermitinae) in the Colombian Amazon

ABSTRACT We report, for the first time, the presence of the termite Ereymatermes rotundiceps Constantino, 1991 as an inquiline of the termite Embiratermes neotenicus (Holmgren, 1906) in the Colombian Amazon, and provide new morphometric information on the species. Soldiers of E. rotundiceps were collected in epigeal nests built by E. neotenicus in pastures during the transition from the dry to the rainy season. The association between host and inquiline termites does not seem to be antagonistic, but the relationship between these two species still needs to be clarified.

摘要 本研究首次报道了圆头埃里白蚁（Ereymatermes rotundiceps Constantino, 1991）作为客居白蚁寄生于哥伦比亚亚马逊地区的幼态嵌长鼻白蚁（Embiratermes neotenicus (Holmgren, 1906)）的巢内，并为该物种提供了全新的形态测量学数据。研究人员于旱季向雨季过渡的阶段，在牧场内幼态嵌长鼻白蚁所构筑的地上巢中，采集到了圆头埃里白蚁的兵蚁。宿主与客居白蚁之间的相互作用似乎并非拮抗关系，但二者的具体物种关系仍有待进一步阐明。
