Oligopogon Loew, 1847: 497 (as subgenus of Dasypogon ). Type species (by monotypy): Dasypogon hybotinus Loew, 1847 .

Diagnosis:A genus, currently assigned to the Stenopogoninae , possessing the following combination of characters, many used to separate it from other members of the subfamily (Londt 2013) as well as character states discussed by Dikow (2009) (his character numbers provided in brackets for convenience). Head: Antennal style with long loosely arranged setae; setae of stylus present on all surfaces (59). Thorax: Prosternum large, abutting proepisternum and prothoracic coxae; dorsal (anterior) margin of prosternum with distinct flange-like projection (75); mesonotum strongly humped; postmetacoxal area membranous; anatergites asetose; pulvilli well developed; alula highly reduced (130); anal lobe and alula reduced and without bordering vein (ie. costa terminates at or before point where anal vein joins wing margin). Abdomen: T2 wider than long (153), but less than twice as long as wide; setae on T8 erect (ie. perpendicular to surface) (168); T10 divided into two heavily sclerotized acanthophorite plates (172); acanthophorite plates with spurs (ie. macrosetae) (174); T9 and T10 partly fused (173); T2–T7 with marginal macrosetae (186–191); lateral ejaculatory process present as a small triangular sclerite (213).
