Feather mites of finfoots (Heliornithidae), a small gruiform family, are poorly and partly erroneously recognized. Grallolichus heliornisi sp. n. (Astigmata: Pterolichidae) is here described from the sungrebe Heliornis fulica as the first representative of the genus commonly found on close relatives of finfoots, Rallidae and Sarothuridae. This species belongs to the species group having ornamented dorsal shields and is morphologically most close to G. proctogamus inhabiting Eurasian coot (Fulica atra). Males of the new species differ from G. proctogamus mainly by the shape of opisthosomal lobes (triangular vs. rounded) and the aedeagus form (parallel sided vs. tapering distally). Females differ mainly by the shape of supranal concavity (open anteriorly vs. closed) and location of setae h1 in relation to supranal concavity (lateral vs. anterior). A key to known species of the genus Grallolichus is provided. The morphological analysis and descriptive characterization of this species, like much of the approximately 2500 feather mite species described to date, were based on mummified mite material preserved in 19th-century old museum bird specimens. These often-forgotten collections are the only source for the analysis of the acarofauna of many rare, unavailable wild or even extinct bird taxa. |
