New Trizetoidea (Acari, Oribatida) from the Philippines

Abstract

Two new species of oribatid mites of the superfamily Trizetoidea (Acari, Oribatida) are described from the Philippines. Eurhynchoribates (Eurhynchoribates) nuevavizcayaensis sp. nov. (Rhynchoribatidae) is similar to E. (E.) pocsi (Mahunka, 1986) in having the interlamellar setae the longest of the setae on the prodorsum, setiform, thickened; mostly long notogastral setae; setiform, thickened aggenital and adanal setae; and localization of ad3 in paraanal and adanal lyrifissures in inverse apoanal positions. It differs by the pointed rostrum, h1 longest of the setae on the notogaster, and the absence of lateral teeth on the rostrum. Suctobelbila trifasciata sp. nov. (Suctobelbidae) is similar to S. baderi Mahunka, 1988 in having two lateral longitudinally oriented ridges on the notogaster, but differs by its larger body size, in having two or three pairs of rostral teeth, three longitudinal notogastral ridges, six pairs of genital setae and the absence of humeral tubercles.
