<i>Galumna (Cosmogalumna) tenensis</i>, a new species of oribatid mite from northwestern Vietnam (Acari: Oribatida: Galumnidae)

Abstract

ABSTRACT The oribatid mite subgenus Galumna (Cosmogalumna) comprises five species. We describe here a species Galumna (Cosmogalumna) tenensis n. sp. collected from northwestern Vietnam. The new species is similar in polygonal networks of notogaster and pteromorphae to Galumna (Cosmogalumna) yonaguniensis Aoki, Citation2009 and Galumna (Cosmogalumna) hiroyoshii (Nakamura and Fujikawa, Citation2004), but differs from the first species by body size, length of rostral setae, morphology of prodorsal integument, and morphology of sensilli; and differs from the second species by body size, shape of rostrum, location of lamellar and rostral setae, and development of interlamellar setae. A diagnostic key to all known species of Galumna (Cosmogalumna) is presented.
