Abstract

Crawfordia hadrovena n. sp. is described from specimens hosted by bee species Protandrena aethiops and P. rugosa from Central Texas. While these host species overlap in their geographical distribution in this region, their flight times and adult presence in the environment are isolated temporally. The description of males of C. hadrovena represents only the second males known in the genus of now nine species. Females have been described for all species but the description of species only using females has not used consistent characters. Thus, taxonomic characters are discussed with the shape of the cephalothorax, nature of the cephalothoracic basal band, nature of the brood canal, and shape of mandibles being important characters for species identification. The lateral portions of the brood canal that were previously thought to be sutures between head and thorax of the cephalothorax or cord-like extensions of the brood canal are now shown to be the lateral sides of the brood canal. A checklist of all species of Crawfordia and their hosts is provided.

文章题目得克萨斯州克劳福德蝇属一新种(链翅目:茎蚜科)及其寄主名录
来自德克萨斯州中部的蜂种proandrena aethiops和P. rugosa宿主的标本描述了克劳馥dia hadrovena n.sp。虽然这些寄主物种在该地区的地理分布重叠,但它们的飞行时间和成虫在环境中的存在是暂时隔离的。C. hadrovena的雄性描述仅代表了目前9种属中已知的第二个雄性。所有物种都描述过雌性,但只使用雌性的物种描述没有使用一致的特征。因此,对其分类特征进行了讨论,其中头胸形状、头胸基底带性质、育雏管性质和下颌骨形状是物种鉴定的重要特征。育雏管的外侧部分以前被认为是头胸之间的缝合线或育雏管的索状延伸,现在被证明是育雏管的外侧。提供了所有种类的克劳福德虫及其宿主的清单。
