Aedes macfarlanei (Edwards, 1914), original combination: Ochlerotatus macfarlanei.
Subfamily Culicinae, tribe Aedini, genus Aedes, subgenus Collessius. The Collessius Group includes seven species.
As described for the subgenus; differing from species of the Alloeomyia Group as follows [characters that provide a polythetic diagnosis of the Group in the phylogeny of Reinert et al. (2009) are indicated with an asterisk (*)]. ADULTS – Proboscis dark-scaled with ventral and lateral patches of pale scales (Ae. hatorii without pale patches); subspiracular area with pale scales. FEMALE GENITALIA – Sternum VIII with median posterior emargination separating broadly rounded lobes, numerous short lanceolate scales and occasionally 1–3 broad scales (Ae. hatorii with posterior margin nearly straight, without lanceolate scales but with several to numerous broad scales); tergum IX elongate; postgenital lobe relatively narrow (somewhat shorter and wider in Ae. hatorii), apex normally flat or with very shallow median emargination; cercus moderately long and broad throughout length, apex broadly rounded, scales absent. MALE GENITALIA – Gonostylus with 1 or more stout subapical setae (these similar to gonostylar claw but somewhat shorter and thinner, especially in Ae. hatorii); aedeagus broader distally than at mid-length. LARVAE – Seta 6-Mx branched; thorax and abdomen covered with minute spicules; seta 1-M,T stout, single or 2-branched, inserted on tubercle. PUPAE – Seta 3-I,II branched; seta 2-VI inserted mesad of seta 1,3-VI; seta 1-VII stout, aciculate, normally single; seta 9-VIII inserted slightly anterior to corner of segment. See subgenus Collessius.
The Collessius and Alloeomyia Groups (as subgenera Collessius and Alloeomyia) were recovered as sister taxa in the morphology-based phylogeny of Reinert et al. (2009), but not in the molecular phylogenetic study of Soghnidian et al. (2017), nor in the phylogenetic analysis of mtDNA COI sequences conducted by Somboon et al. (2023), which included species 12 other genera of Aedes (see subgenus Collessius).
Immature stages are normally found in rock pools but also occur in artificial containers (e.g. concrete water tanks). Females of some species bite humans indoors and outdoors. Nothing else is known about the biology of members of the Collessius Group.
Species of the Collessius Group are of no known medical or economic importance.
Species of the Collessius Group occur principally in the Oriental Region, but some are also found in the Manchurian Subregion of the Palaearctic. Species are recorded from China, India, Indonesia, Japan, Malaysia, Pakistan, Sri Lanka, South Korea, Taiwan, Thailand and Vietnam.
