 Diagnosis. This species can be recognized by the following unique combination of characters: the integument is black; the body is patterned with silvery and darker pubescence (Fig. 7A); the propodeum bears distinct conical processes posterolaterally; and the Cu vein is distinctly deflected downward at base forming a posterior pocket in the second medial cell.

[ince], Punta Cana, 13–14.IX.2008, Sand Hill, M [alaise]T[rap]; 1 ♂, Punta Cana, 11.IX.2008, West Biodiv. [ersity] Center, Sweep (EMUS).   
 Distribution. Throughout USA to southern Costa Rica (Wasbauer & Kimsey 1985), Cuba (Genaro 1996, Portuondo &Fernández 2003, Ferrer & Triana 2004), and Dominican Republic.   
 Host. Wasbauer and Kimsey (1985) recorded six species of spiders used as a host by A. medianus: Oxyopes salticus Hentz (Oxyopidae), Maevia vittata (Hentz) (Salticidae), Phidippus whitmani Peckham & Peckham (Salticidae), Phidippus sp. (Salticidae), Salticus sp. (Salticidae), Tibellus duttoni (Hentz) (Salticidae), and Xysticus sp. near gulosus (Thomisidae).   
 Remarks. This is a very common species that is easily separated from any other Dominican Republic Pompilidae by the presence of conical processes on the propodeum (Fig. 8F). This species is often observed in open, sandy areas (Wasbauer & Kimsey 1985) and are easily collected in pan traps. Adults of both sexes have been observed feeding from honeydew secretions and extrafloral nectaries of various plant species. This is the first record of the species for the Dominican Republic.
