The oribatid mite subgenus Galumna (Galumna) (Acari, Oribatida, Galumnidae) in the Philippines

Abstract

Five species of the subgenus Galumna (Galumna) (Acari, Oribatida, Galumnidae) are registered in the Philippine oribatid mite fauna. A new species, G. (G.) makilingensis sp. n., is described; it is most similar morphologically to G. (G.) tokyoensis Aoki, 1966, but differs from the latter by the morphology of porose areas Aa and Ap, rostral setae, and length of interlamellar setae. Three species, G. (G.) crenata Deb & Raychaudhuri, 1975, G. (G.) cf. exigua Sellnick, 1925 and G. (G.) khoii Mahunka, 1989, are recorded in the Philippines for the first time. The species G. (G.) crenata is redescribed. An identification key to the Philippine species of cGalumna (Galumna) is given.
