| Summary: | Genus Pergalumna Grandjean, 1936 Type species: Oribates nervosus Berlese, 1914, p. 127) Without sexual dimorphism in prodorsum and notogaster, notogaster rounded posteriorly in both genders. Body surface usually without strongly developed sculpture or ornamentation, rarely foveolate, striate or granulate/ rugose, pteromorphs partially reticulate. Rostrum rounded, pointed or with trapezoid ledge. Lamellar and sublamellar lines present, long, thin, parallel, curving backwards at ventral end. Rostral setae medial to lamellar lines and distanced from them. Lamellar setae medial to lamellar lines. Bothridial setae strongly diverse morphologically. Dorsosejugal suture and postanal porose area absent or present. Notogastral setae represented by 10 pairs of alveoli (exceptionally microsetae), one pair on pteromorphs. Octotaxic system represented by porose areas, saccules absent, one pair of Aa (rarely two). Median pore absent or present in females and males, undivided or rarely subdivided (several parts), sometimes females with median pore, males without it. Pteromorphs clearly bilobed. Without thorn-like structures behind pteromorphs, dark band anterior to genital aperture and anal and adanal neotrichy. Adanal lyrifissures located close and lateral to anal aperture. Leg tarsi with three or two claws. Leg setae not modified. Statement of monophyly: Non-monophyletic; the largest subgenus ( Pergalumna ( Pergalumna )) forms multiple independent lineages on tree (Fig. 1), another subgenus, Pergalumna ( Bigalumna ), is monotypic Distribution: Cosmopolitan (except Antarctic region) Number of known taxa: two subgenera, 156 species Published as part of Ermilov, Sergey G. & Klimov, Pavel B., 2017, Generic revision of the large-winged mite superfamilY Galumnoidea (Acari, Oribatida) of the world, pp. 1-72 in Zootaxa 4357 (1) on page 33, DOI:10.11646/zootaxa.4357.1.1, http://zenodo.org/record/1066658 |
