Aedes pseudonigeria (Theobald, 1910), original combination: Stegomyia pseudonigeria.
Subfamily Culicinae, genus Aedes, subgenus Stegomyia. The Pseudonigeria Group includes five species.
Species of the Pseudonigeria Group are distinguished from other species and groups of subgenus Stegomyia by the following combination of characters (adapted mainly from Huang, 1988, 2004). ADULTS ‒ Maxillary palpus with pale scaling; scutal fossa with a patch of broadened pale falcate scales, dorsocentral setae present; scutellum with broad pale scales on all lobes; paratergite with broad pale scales; subspiracular area with broad pale scales; postspiracular scales absent; all femora with pale knee spot; all tibia with pale band; hindtarsomeres 1 and 2 with basal pale band, hindtarsomere 3 with or without pale band, hindtarsomere 4 entirely pale-scaled in Afrotropical species (Ae. mickevichae, Ae. pseudonigeria, Ae. saimedres), with basal pale band in eastern Asian species (Ae. chemulpoensis, Ae. wadai), hindtarsomere 5 entirely pale or entirely dark . MALE GENITALIA ‒ Group characters not established; males of Ae. mickevichae and Ae. saimedres unknown.. LARVAE ‒ Unknown except for Ae. chemulpoensis, Ae. pseudonigeria (as synonym Danielsia wellmanii Theobald) and Ae. wadai, only fully described and illustrated for the first and third species by Tanaka et al., 1979). PUPAE ‒ Unknown for Afrotropical species; pupae of Ae. wadai and Ae. chemulpoensis described by Tanaka, 2000, 2001, respectively. See subgenus Stegomyia.
The affinities of the Pseudonigeria Group are unknown and will remain so until the species and species groups of subgenus Stegomyia are better known and studied using objective methods of phylogenetic analysis. Huang (1988), however, surmised that species of the group show affinities with species of the Aegypti Group.
Larvae of Ae. chemulpoensis, Ae. pseudonigeria and Ae. wadai are known to develop in tree holes (Robinson, 1948, Ae. chemulpoensis as Ae. wellmanii; Tanaka et al., 1979). Females of Ae. mickevichae, Ae. pseudonigeria and Ae. saimedres are known to bite humans (Huang, 2004).
The species of the Pseudonigeria Group are not known to be of medical importance to humans.
Three species of the Pseudonigeria Group occur in the Afrotropical Region; two occur in the far eastern Palaearctic Region. Aedes mickevichae is recorded from Kenya; Ae. Pseudonigeria from Angola, Botswana, Namibia and South Africa; and Ae. saimedres from Botswana, Namibia. Aedes chemulpoensis is known to occur in China and South Korea; Ae. wadai is known only from Japan.
