The genus Scapheremaeus (Acari,Oribatida, Cymbaeremaeidae) in the oribatid mite fauna of New Zealand,with description of two new species

Two new species of oribatid mites of the genus Scapheremaeus (Oribatida, Cymbaeremaeidae), Scapheremaeusgibbussp. n. and Scapheremaeusluxtonisp. n., are described from New Zealand. Scapheremaeusgibbussp. n. is morphologically most similar to Scapheremaeushumeratus Balogh & Mahunka, 1967, but differs from the latter by the number of notogastral, genital and adanal setae, morphology of bothridial setae, position of adanal lyrifissures and absence of humeral processes. Scapheremaeusluxtonisp. n. is morphologically most similar to Scapheremaeusyamashitai Aoki, 1970, but differs from the latter by the morphology of notogastral and rostral setae, morphology of leg solenidia φ₂ and development of humeral processes. The species Scapheremaeuszephyrus Colloff, 2010 is recorded for the first time in New Zealand. An identification key to the known New Zealand species of Scapheremaeus is provided.
