03BF5D28B85FFFD077C7AF4888C54420.taxon	discussion	Comments. Argolepida is a small genus of diminutive flies with a body length rarely more than 7.5 mm. This is a very distinctive genus with a number of distinguishing features including the eyes of both sexes being widely separated, extensive pile of adpressed silver-white and black scale-like setae over the entire body, legs with elongate pale macrosetae and claws, and pulvilli small. There is limited sexual dimorphism in this genus with the frons only slightly narrower and vestiture only slightly more extensive in the male; the main sexually dimorphic feature is the presence and shape of the frontal glabrous patch (Fig. 32), which is larger and frequently characteristically shaped in the female. Males and females are also similarly sized. All species of Argolepida are restricted to the Chacoan, Monte and Patagonian provinces. Argolepida is placed in the Cerocatus genus group and is closely related to Dasythereva and Elcaribe Webb, 2006. Dasythereva and Argolepida share features such as the wide frons in both sexes and preponderance of scale-like setae over the body. The presence of setae on the metakatepisternum is rare in stiletto flies and is known only in Argolepida (some species) and Elcaribe.	en	Irwin, Michael E., Winterton, Shaun L.

03BF5D28B84DFFC577C7AC948F594763.taxon	discussion	Comments. The frontal patch is distinctive for this species and its shape is reminiscent of a ‘ tulip’ or ‘ crown’, and unlike other Argolepida species, the frontal patch is similarly large in both sexes, although slightly smaller and more parallel sided in the male. As noted by Webb et al. (2013), the lectotype designation by Metz et al. (2003) was unjustified as Kröber (1928) clearly distinguished a type and co-type in his original description. Argolepida rivulosa has a relatively broad distribution, being recorded in Argentina, Bolivia and Uruguay.	en	Irwin, Michael E., Winterton, Shaun L.
