摘要

种类繁多的蜜蜂属Psaenythia Gerstaecker(蜜蜂科:Protandrenini)，迄今为止在南美洲中部和南部已知，首次在南美洲北部记录。描述了两个新种:产自哥伦比亚东北部的Psaenythia diceratops, sp. n.和产自委内瑞拉中部的P. guaricoensis, sp. n.。雄性独角龙具有突出的顶端外侧直棱角，细长的镰刀状下颌骨，并具有强烈的二态性的大头畸形。

The bee genus Psaenythia in northern South America (Hymenoptera: Andrenidae)

The diverse bee genus Psaenythia Gerstaecker (Panurginae: Protandrenini), hitherto known from central and southern South America, is recorded from northern South America for the first time. Two new species are described: Psaenythia diceratops, sp. n., from northeastern Colombia, and P. guaricoensis, sp. n., from central Venezuela. The males of P. diceratops are noteworthy for possessing prominent apicolateral clypeal horns, elongate scythe-like mandibles, and displaying macrocephaly with strong dimorphism.
