Aedes hortator Dyar & Knab, 1907.
Subfamily Culicinae, tribe Aedini, genus Aedes. Subgenus Sallumia includes only two species. Subgenus abbreviation – Sal.
Subgenus Sallumia is characterised and distinguished from other generic-level taxa of Aedini by the following combinations of characters. Characters that diagnose Sallumia (as genus) in the preferred cladogram of Reinert et al. (2009), based on Ae. hortator, are indicated by an asterisk (*).

Reinert et al. (2008) found the clade comprised of subgenera Sallumia + (Geoskusea + (Levua + Rhinoskusea)) deeply nested within Ochlerotatus. In the more comprehensive study of Reinert et al. (2009), the same clade was placed in a sister relationship to a large terminal clade comprised generic-level taxa other than Ochlerotatus. In the phylogeny of Wilkerson et al. (2015), Sallumia formed a polytomy along with subgenera Geoskusea, Levua and Rhinoskusea, and this group was sister to subgenus Cancraedes.
The immature stages of species of subgenus Sallumia are found in temporary pools (Ae. hortator) and crab holes (Ae. perventor). The females of Ae. hortator are known to attack humans in wooded areas.
Species of subgenus Sallumia are not known to be of medical importance to humans.
Sallumia is a Neotropical taxon, with species occurring in countries from Bolivia northward to Trinidad. Aedes hortator is recorded from localities in Bolivia, Brazil, Colombia, French Guiana, Peru, Surinam, and Trinidad and Tobago. Aedes perventor is known from localities in Brazil and French Guiana.
