Female holotype from Pluvialis apricaria (Linnaeus) ( Charadriiformes : Charadriidae ), FRANCE : St. Malo, 1970, no other data. Type deposition. Holotype in AMU . Differential diagnosis. Female of Charadriineopicobia apricaria sp. nov. differs from two other described species of this genus by the absence of the hysteronotal shields; presence of short pseudanal setae but not as miocrosetae, and by the position of agenital setae ag2 which are situated posteromedial to setae ag3 . In females of Ch. calidris and Ch. leucophaeus , the hysteronotal shield is present; pseudanal setae are as microsetae and setae ag2 are situated anteromedial to setae ag3 . Etymology. The name of this species refers to specific name of the host— Pluvialis apricaria .
