Hawaiian Drosophilidae: Ciliated Tarsus Subgroup II

Hawaiian Drosophilidae diversity can be illustrated in the morphological variation of the male foreleg. This feature is unknown in other Diptera families. One of the four subgroups of the modified tarsus flies is the "ciliated-tarsus group". This group is characterized by strong, thickened setae, or bristles, on the basitarsus. This group is also defined by what it lacks - which are additional modifications that are found among the other subgroups of modified tarsus flies. The modified thickened setae are thought to be the result of sexual selection and are used for courtship purposes. Please contribute and help transcribe UHIM's ciliated-tarsus fly specimens in order to better our understanding of their distribution here in Hawai'i.This expedition of 662 tasks is fully transcribed and validated.

夏威夷果蝇科（Drosophilidae）的物种多样性可通过雄性前足的形态变异得以直观展现，该特征在其他双翅目（Diptera）类群中尚无记录。特化跗节果蝇（modified tarsus flies）共分为四个亚群，其中之一为“纤毛跗节类群（ciliated-tarsus group）”。该类群以基跗节（basitarsus）上粗壮增厚的刚毛（setae，又称鬃bristles）为典型鉴别特征；同时，其界定还依托于缺失的特征——即特化跗节果蝇其余亚群所具备的额外特化结构。研究认为，这类特化增厚的刚毛系性选择的产物，用于求偶行为。诚邀各界协助转录UHIM（夏威夷大学昆虫博物馆，University of Hawaii Insect Museum）所藏纤毛跗节果蝇标本，以增进我们对该类群在夏威夷群岛分布状况的认知。本次涵盖662项任务的科考项目已完成全部转录与验证工作。
