Australian beach sand is a productive habitat for lower brachyceran fly larvae but often overlooked by collectors. We collected two species of tabanid larvae from coastal beach sand in southern New South Wales in August 2013. Both species belong to the Dasybasis macrophthalma species-group of Mackerras (1959), one a new species, and the other D. exulans (Erichson, 1842). We describe both new immature stages and the new species adult as Dasybasis rieki sp. nov. (Diptera: Tabanidae: Diachlorini). Trojan (1994b) elevated the D. macrophthalma species group to the genus Sznablius. We review the evidence for the generic status of Sznablius, and synonymize it with Dasybasis.
澳大利亚海滩沙地是低等短角亚目蝇类幼虫的多产栖息地，但常被采集者忽视。2013年8月，我们从新南威尔士州南部的沿海海滩沙地采集到两种虻科幼虫。这两个物种都属于麦克拉斯（1959年）的大眼达斯巴西斯物种组，一种是新物种，另一种是流亡达斯巴西斯（埃里克森，1842年）。我们描述了这两个新的未成熟阶段，并将新物种的成虫描述为里氏达斯巴西斯新种（双翅目：虻科：双氯虻属）。特罗扬（1994b）将大眼达斯巴西斯物种组提升为斯纳布柳斯属。我们审查了斯纳布柳斯属地位的证据，并将其与达斯巴西斯属同义。
