Hawaiian Drosophilidae: Bristle-foot Subgroup II

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 609 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展现。该特征在其他双翅目（Diptera）类群中尚未见报道。特化跗节蝇类的四个亚群之一为‘鬃足类（bristle-foot）’或‘鬃跗类（bristle-tarsus group）’。该类群的典型特征为基跗节（basitarsus）上着生1至2列加粗的刚毛（setae）。此类形态特化被认为是性选择的产物，且被用于求偶行为。为增进对夏威夷地区该类群分布状况的认知，恳请协助转录UHIM收藏的鬃足类标本。本次涵盖609项任务的科考数据已完成全部转录与验证工作。本数据集资源将定期同步至核心物种出现记录索引库。
