Abstract

Chironomidae of symbiotic habits have been recorded in different parts of the world, among commensals and parasites. There are different genera reported at the moment, however questions such as the origin of commensal or parasitic life, which occurred first or what are their benefits remain debatable. In order to contribute with information to elucidate the above mentioned issues, the present study reports the finding of immature stages of Symbiocladius (Acletus) wygodzinskyi Roback, 1965 in the Churup stream located in the Andes Cordillera (Peru), living on nymphs of Leptophlebiidae (Ephemeroptera). We present a morphological description of immature stages of this species and for the first time the sequence of COX1 gene S. (A.) wygodzinskyi. The genetic result also supports differences between the morphospecies of Symbiocladius (Symbiocladius) rhithrogenae Zavřel, 1924 and S. (A.) wygodzinskyi in 23%.

摘要

共生习性的摇蚊科已在世界不同地区被记录下来，包括共生和寄生。目前有不同的属被报道，但共生或寄生生活的起源、哪种情况先发生以及它们的好处等问题仍存在争议。为了为阐明上述问题提供信息，本研究报告了在位于安第斯山脉（秘鲁）的 Churup 溪流中发现的共生的 Symbiocladius (Acletus) wygodzinskyi Roback, 1965 的未成熟阶段，它们生活在 Leptophlebiidae （蜉蝣目）若虫上。我们对该物种的未成熟阶段进行了形态描述，这也是首次对 COX1 基因 S. (A.) wygodzinskyi 进行了测序。遗传结果也支持 Symbiocladius (Symbiocladius) rhithrogenae Zavřel, 1924 和 S. (A.) wygodzinskyi 之间在 23%的形态种水平上存在差异。
