摘要

摘要：在巴西东南部发现了第一个已知的新热带无尾木犀属物种——白叶木犀（Alavesia leukoprospa，sp.nov.）。正模标本（也是迄今为止唯一的标本）是用Malaise陷阱在一个半干旱季节性森林（干燥森林）和开放的完全次生植被受到强烈影响的地区采集的。它是在仲春收集的，但到目前为止还没有被再次收集。白蜡木属与该属仅有的另外两个现存物种（已知于纳米比亚的Brandberg Massif）有一些衍生特征，这表明所有三个现存物种可能共同组成一个小分支，与白蜡木白垩纪的大部分多样性分离。

First Known Extant Species of Alavesia (Diptera: Atelestidae) in the Neotropical Region: Alavesia leukoprosopa, sp. nov., from the Southern Atlantic Forest, Brazil

ABSTRACT A first known extant Neotropical species of the atelestid genus Alavesia—Alavesia leukoprosopa, sp. nov.—is described from southeastern Brazil. The holotype (and only specimen so far) was collected with a Malaise trap in an area with strongly impacted semideciduous seasonal forest (dry forest) and open, entirely secondary vegetation. It was collected in mid spring, but has not been collected again so far. Alavesia leukoprosopa shares some derived features with the only two other extant species of the genus, known from the Brandberg Massif in Namibia, suggesting that all three extant species may compose together a small clade separate from the bulk of the Cretaceous diversity of Alavesia.
