Examined material. Holotype, ♀. HONDURAS: Cortés, Parque Nacional Cusuco, 5 Km N Buenos Aires, 15°29’N 88°13’W, Malaise trap in oak/pine cloud forest, R. Cave leg., 30.VII.1995 ( MZLU). Allotype, ♂. HONDURAS: Francisco Morazan, Parque Nacional La Tigra, 14°15’N 87°05’W, Malaise trap in oak/pine cloud forest, R. Cave leg., 4♂ 27.x.1995 ( MZLU).

Distribution. Honduras.

Etymology. This species was named in honor of Marius Wasbauer who has greatly contributed to the knowledge of Nearctic and Neotropical biodiversity for Pompilidae .

Variation. Last antennal segment of female can be more or less dark, looking yellow in some specimens and brown in others.

Host. Unknown.

Remarks. This species belongs to the subgenus Umbripennis. Priocnemis wasbaueri has the hind outer angle of the third submarginal cell acute and the female has distinct well-developed chevron teeth on the hind tibia. The male hind tibia, however, only has weakly developed teeth. Umbripennis only has three other described species in the New World: P. m i no r a t a Banks, P. nigripes (Cresson) and P. oregona Banks , all of which are found in the USA. None of these species have been reported from Mexico or further south. Priocnemis wasbaueri will key to P. minorata in Townes (1957). It, however, is easily separated from this species. Priocnemis wasbaueri has yellow flagellomeres with the apical flagellomere being slightly infuscated in the female, and the apical three to four flagellomeres being black in the male, while the antenna of P. minorata is completely black in both sexes. The apical margin of the clypeus of both sexes is truncated in P. wasbaueri , while the margin is broadly, but weakly emarginated, in the female, and broadly and deeply emarginate in the male of P. minorata .
