Redescription of Alcedinectes alcyon (Acari:Hypoderatidae) from the belted kingfisher (Aves:Coraciiformes; Alcedinidae).
Alcedinectes alcyon (Boyd) is redescribed based on specimens collected from its belted kingfisher, Megaceryle alcyon (L.), type host in Florida. This species differs from A. cerylei Fain by the chaetotaxy of tarsus III. A. alcyon has a long stout apical seta that tapers to a curved tip resembling that seen on tarsus III of the genus Tytodectes (Ispidectes) Fain. The equivalent seta in A. cerylei is a stout spine. There are other minor differences between these species in the pattern of idiosomal sclerotization and leg chaetotaxy. The chaetotaxy and solenidiotaxy of legs I and II in Alcedinectes closely resemble that of Amazonectes psittaci Fain & Vercammen-Grandjean from parrots (Psittaciformes), whereas the morphology and chaetotaxy of the idiosoma resemble that of Tytonectes (Ispidectes) spp. which also occurs in kingfishers (Coraciiformes). The long stout seta that tapers to a curved tip on tarsus III in A. alcyon also links the genus Alcedinectes with Tytodectes (Ispidectes).
