First record of the genus Sacculogalumna (Acari: Oribatida: Galumnidae) from the Philippines, with description of a new species

Abstract

The oribatid mite genus Sacculogalumna (Oribatida: Galumnidae) is recorded in the Philippines for the first time. A new species, S. samarensis n. sp., is described from secondary forest litter in the Western and Eastern Samar Provinces in Samar Island. It differs from S. saccularis and S. suiyangensis in having pointed rostrum, setiform bothridial setae, reticulate pteromorphs, long and thickened adanal setae ad1 and ad2 and one seta on anterior edges of genital plates, by the location of lamellar setae between lamellar lines, and the absence of postanal porose area, and by the medially interrupted dorsosejugal furrow. The inclusion of the new species in Sacculogalumna is proved, and an identification key to known species of the genus is given. http://zoobank.org/urn:lsid:zoobank.org:pub:4D40D41A-EF5C-423D-AAB3-857C16B10BE8
