Type host: Calidris canutus ( Linnaeus, 1758)

Other hosts: Calidris canutus rufus ( Wilson, 1813) , Calidris canutus rogersi ( Mathews, 1913) , Aphriza virgata (J.F. Gmelin, 1789) .

Diagnosis: Marginal carina narrow ( Fig. 8a), but bulges out at DSMS. Dorsal preantennal suture may be interrupted medially, and in females bends anteriorly to reach or envelop the ADS. Ventral anterior plate small, and triangular (occasionally rounded posteriorly). Lateral nodi moderately developed, and dark preantennal bands weak but broad. AVS3 slightly anterior to AVS2.

Abdominal tergites II–III in both sexes with wedge-shaped median indentation of the anterior margin, reaching more than a third of the tergite width ( Fig. 8b). Indentations present in segments IV–V as well, but these are generally less pronounced. Paratergal plates broad. Tergal heads small and dark, appearing only as dark bars.

Female genital lobes with 5–6 posterior marginal setae, 4–6 sub-marginal setae, and 5–6 median marginal setae ( Fig. 8c). Parameres gently curved, and very slender distally ( Fig. 8d). Mesomere roughly triangular, with straight lateral sides. Lower endomere connected to apodemal bridge by a small triangle.

Discussion: Similar to L. mintoni sp. nov., but differs in the median indentations of the tergites, and in the shape of the parameres. Also, these two species are well separated genetically ( Gustafsson and Olsson, 2012). The marginal carina is as thin as in L. nereis , but is not of even thickness as in this species.

No significant differences have been found between material from C. canutus canutus , C. canutus rogersi , and C. canutus rufus . The material from Aphriza virgata differs slightly from that from C. canutus in that the females are overall longer and broader, they lack the wedge-shaped indentation of tergite III, and have only 5 median marginal setae. The males are more similar in morphology and measurements, but the shape of the mesomere is slightly different, and the parameres are longer in A. virgata material than in C. canutus ssp. material . However, not enough specimens of Lunaceps from A. virgata are available to draw any definite conclusion about their taxonomic status.

Etymology: Named in honour of Rudolf Drost (1892–1971), Director of the Vogelwarte Helgoland, Institut für Vogelforschung, in Wilhelmshaven, who among other things studied factors that influenced bird migration and aging and sexing criteria for captured birds ( Thomson, 1973).
