| This paper examines the status and geographic distribution of the genera Hypenetes Loew and Tillobroma Hull; the status of the latter was shifted to generic level by Artigas & Papavero 1991. The genus Clavator Philippi, which is preoccupied, becomes synonymous to Tillobroma Hull, this has been proposed by Artigas & Papavero (1991), and is confirmed here. Hypenetes and Tillobroma have a possible common Gondwanan origin of approximately 180 millions years ago. Even though the external characters barely allow separation between the two genera, the obvious differences in spermathecae structures permit the inference of other internal differences and reinforce the independent status of the genera. This conclusion is also supported by 180 million... |
