Two new species of the family Suctobelbidae (Acari, Oribatida) from Chile

Resumo

Two new species of the oribatid mite family Suctobelbidae (Acari, Oribatida) are described from southern Chile. Niosuctobelba sphagnicola Ermilov, sp. n. differs from N. ruga Chinone, 2003 in the rostrum with a median incision and one pair of lateral teeth, the heads of bothridial setae rounded distally, the tectopedial fields not fused anteriorly, the notogastral setae barbed, and the body without striate ornamentation. Zeasuctobelba tierradelfuegoensis Ermilov, sp. n. differs from Z. trinodosa Hammer 1966 in a shorter body, the heads of the bothridial setae with thin apices, the tectopedial fields not fused anteriorly, and the notogastral humeral tubercles with longer cristae. An identification key to the known species of Zeasuctobelba is given. The genus Niosuctobelba is recorded for the Neotropical Region for the first time, while Zeasuctobelba is new to the fauna of Chile.
