Hawaiian Drosophilidae: Bristle-foot Subgroup I

Hawaiian Drosophilidae diversity is 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 "bristle-foot" or "bristle-tarsus group". This group is characterized by one to two rows of thickened setae, or bristles, on the basitarsus. These modifications are thought to be the result of sexual selection and are used for courtship purposes. Please contribute and help transcribe UHIM's bristle-foot specimens in order to better our understanding of their distribution here in Hawai'i.This expedition of 535 tasks is fully transcribed and validated. This data resource is harvested periodically into the main occurrence index.

夏威夷果蝇科（Drosophilidae）的多样性可通过雄性前足的形态变异得以直观体现。该形态特征在其他双翅目（Diptera）类群中尚未见报道。特化跗节果蝇的四个亚群之一，便是‘鬃足类（bristle-foot）’或‘鬃跗类（bristle-tarsus）’群。该类群的典型鉴别特征为基跗节（basitarsus）上分布有1至2列加粗的刚毛（setae）或鬃毛。这类形态特化被认为是性选择的演化产物，其功能为求偶行为。诚邀各位协助转录UHIM所藏的鬃足类标本，以深化我们对该类群在夏威夷群岛分布状况的认知。本次涵盖535项任务的考察工作已全部完成转录与验证流程。该数据集资源将定期同步至核心物种出现索引库。
