Wild bees represent a global group of highly diversified insect pollinators, nowadays concerningly well known for their widespread observed patterns of decline. Amongst them is the genus Dasypoda, a widespread Palearctic clade of solitary bees generally poorly represented in entomological collections. Among the 39 accepted species of the genus, 35 are known by both sexes, and a large number of taxa are still known by a low number of specimens. The recently described taxon Dasypoda (Heterodasypoda) michezi Radchenko, 2017 endemic to southern Portugal is just such a case. The species was described from two male specimens, but no female material has been known to date. Here, we provide the first description of the female of D. michezi, collected close to the locus typicus in southern Portugal along with a series of conspecific males. Sex pairing is proposed based on the sympatry of the male and female specimens and on the similar morphology of non-sexual dimorphic traits and on the barcode of a fragment of Cytochrome Oxidase I. We provide high quality imaging of both sexes of D. michezi to help future identification of the species and present a key for all known species of the subgenus Heterodasypoda. We finally propose an IUCN status for D. michezi and discuss the conservation of such geographically restricted species in the current context of global change.

多样性热点（膜翅目、,科，Dasypoda）中特有蜜蜂的评估和保护状况

野蜂代表着高度多样化的昆虫授粉媒介的全球群体，如今以其普遍观察到的下降模式而广为人知。其中之一是达西波达（Dasypoda）属，这是一种广泛的孤蜂进化支，通常在昆虫学收藏品中代表性较弱。在39个公认的属中，有35个是男女已知的，仍然有少量的标本知道大量的分类单元。最近描述的2017年葡萄牙南部特有的分类单元达西坡达（Heterodasypoda）米切兹·拉琴科（Machezi Radchenko）就是这种情况。该物种是从两个雄性标本中描述的，但是迄今为止还没有雌性材料。在这里，我们提供了D. michezi雌性的第一个描述，该雌性与一系列同种雄性一起被收集在葡萄牙南部的Typicus附近。基于男性和女性标本的象征，非性二态性状的相似形态以及细胞色素氧化酶I片段的条形码，提出了性别配对。我们提供了D. michezi的两性的高质量成像帮助将来鉴定该物种，并为异源亚目亚目的所有已知物种提供密钥。我们最终提出了D. michezi的IUCN地位，并讨论了在当前全球变化的背景下保护此类受地理限制的物种的方法。michezi可以帮助将来识别该物种，并为杂种亚目（Heterodasypoda）的所有已知物种提供密钥。我们最终提出了D. michezi的IUCN地位，并讨论了在当前全球变化的背景下保护此类受地理限制的物种的方法。michezi可以帮助将来识别该物种，并为杂种亚目（Heterodasypoda）的所有已知物种提供密钥。我们最终提出了D. michezi的IUCN地位，并讨论了在当前全球变化的背景下保护此类受地理限制的物种的方法。
