Subgenus Pseudalbuginosus Huang & Rueda, 2015

Type species: 

Subfamily Culicinae, tribe Aedini, genus Aedes. Subgenus Pseudalbuginosus is monobasic. Subgenus abbreviation – Pal.


Subgenus Pseudalbuginosus is diagnosed and distinguished from all other generic-level taxa of Aedini based on features of the adults (immature stages unknown).  ADULTS –  Vertex of head with numerous erect scales (not restricted to occiput) and patch of broad decumbent pale scales on either side above margin of compound eyes; maxillary palpus of males about as long as proboscis, with 5 palpomeres, palpomeres 4 and 5 short, combined length shorter than length of palpomere 3, slightly downturned and setose, palpomere 5 with broad pale band at base; proboscis of male with a complete pale band at mid-length; antennal pedicel with patch of broad pale scales on mesal surface; scutum with large silvery patch of broad scales on anterior scutal fossal area; acrostichal setae present; scutellum with broad pale scales on all lobes; paratergite with broad pale scales; subspiracular area without scales; postspiracular setae present; lower prealar scale-patch absent; lower mesepimeral setae absent; postprocoxal membrane without scales; hindfemur and -tibia with apical pale spot, hindtarsomeres 1‒4 with apical pale bands, hindtarsomere 5 entirely pale. MALE GENITALIA ‒ Tergum IX short, constricted medially, with 4 or 5 setae posteriorly on either side of shallow median emargination, lobes unapparent; gonostylus attached at apex of gonocoxite, long, basal 0.6 narrow, broader distally with prominent dorsal process bent toward apex; gonostylar claw broad, leaf-like, inserted slightly before apex; claspette elongate, somewhat carrot-shaped with 2 short setae at apex; aedeagus strongly toothed; paraproct rather long, rounded apically, 3 cercal setae present. See Aedes.

Phylogenetic relationships: 

The affinities of subgenus Pseudalbuginosus are unknown. Huang & Rueda (2015) stated that the subgenus “possesses some rather important basic characters in common” with subgenera Aedimorphus, Albuginosus, Diceromyia and Stegomyia, thus clearly indicating that Pseudalbuginosus, like most generic-level taxa of Aedini, is a polythetic taxon that is diagnosed by a unique combination of characters.

Bionomics and disease relations: 

The immature stages of the sole species of subgenus Pseudalbuginosus are unknown and nothing is known about the bionomics of the adults.

Aedes grjebinei is unlikely to be of medical importance to humans.


The only known species of subgenus Pseudalbuginosus is recorded from localities in Cameroun and Gabon.
