Description. FEMALE (holotype). Gnathosoma. Infracapitulum apunctate. Each medial branch of peritremes with 3 chambers, and lateral branch with 4 chambers. Stylophore densely punctate. Idiosoma. Propodonotal shield densely punctate in anterior half; 4 apunctate patches present. Setae vi, ve and si beaded. Setae c1 situated slightly anterior to level of setae se. Hysteronotal shields absent. Pygidial shield apunctate, pear-like in shape. Agenital and genital plates absent. Setae ag2 situated slightly posteromedial to setae ag3. Pseudanal setae ps1 short but not as microsetae.

Length ratios of setae: vi: ve: si 1:2.8:4, f1: f2 1:2, h1: f1 1:1, ag1: ag2: ag3 1.4:1:1.9, tc’III–IV: tc”III–IV 1:1.4, 3b: 3c 1:2.8.

MALE. Unknown.

Type material. 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.
