Aedes seoulensis Yamada, 1921.
Subfamily Culicinae, tribe Aedini, genus Aedes, subgenus Hopkinsius. The Yamada Group includes two species.
The following combination of characters distinguishes species of the Yamada Group from those of the Hopkinsius Group. Characters that diagnose the group (as subgenus Yamada) in the phylogeny of Aedini recovered by Reinert et al. (2009) are indicated by an asterisk (*). ADULTS – Ocular scales of head narrow; *scutum with pale scales covering anterior 0.7 of combined anterior acrostichal and anterior dorsocentral areas, *stripe of pale scales absent from posterior dorsocentral area; *anterior dorsocentral setae absent; *postpronotal scales all narrow; hindfemur without distal pale scales, *hindtibia with areas of pale scales; terga II–VI with narrow basal pale bands (incomplete in Ae. albocinctus) and basolateral pale patches; *abdominal terga of males with numerous moderately long setae. FEMALE GENITALIA – Cercus wider proximally than distally. MALE GENITALIA – *Tergum IX setae all slender; sternum IX relatively short; gonocoxite with poorly defined basomesal lobe bearing few slender setae and *1 long stouter seta; claspette with narrow moderately long columnar stem. LARVAE – Seta 14-C with few branches; seta 19-C absent; seta 4-P shorter than seta 3-P; *seta 2-II single; seta 8-II single; comb comprised of *numerous scales in patch; seta 2-X with 3 or 4 branches. PUPAE – Seta 5-CT longer than seta 4-CT; *seta 7-CT more than 6 times length of seta 6-CT; seta 5-IV–VI branched, longer than 1.5 length of following tergum; seta 1-Pa with 2–4 branches. See subgenus Hopkinsius.
The Yamada and Hopkinsius Groups (as subgenera Yamada and Hopkinsius) were recovered as monophyletic sister taxa in the morphology-based phylogeny of Reinert et al. (2009), but their affinities with other groups of Aedini are not clearly identified.
The immature stages have been collected from tree holes. Females of Ae. seoulensis are known to bite humans during the daytime. Nothing else is known about the bionomics of species of the Yamada Group.
Species of the Yamada Group are not of medical importance to humans.
Species of the Yamada Group have are recorded from India, Japan, China, South Korea and Taiwan.
