Mahunka Oribatid mites (Acari: Oribatida) from Madagascar - III: Some microzetid species —A study on microzetid oribatid mites collected in Madagascar. Five species are emended, three of them new to science. Some taxonomical notes on the relationships of the genus Comorozetes Mahunka, 1994 and Hymenozetes Balogh, 1962. Megazetes nosybe Mahunka, 1993 = Magoebazetes nosybe (Mahunka, 1993). With 11 figures. INTRODUCTION For quite some time I have been making research into the oribatids of Madagascar (Malagasy Republic), e.g. Mahunka 1996. During his recent expedition, my friend, Prof. Dr. Tamás Pócs, collected and extracted on the spot new material to enable further study. The results of my research are published in parts. In the present publication I give the description three microzetid species, all are new to science. I also give new locality data referring to the two known species. In the descriptions and the terminology I follow those of my previous papers (e.g. Mahunka 1997). Comorozetes concurvatus sp. n. (Figs 1-4) Description — Measurements: Length: 378-422 pm, width: 318-335 pm. Prodorsum: Rostrum wide, narrowing anteriorly, with an excavated median apex. Rostral setae arising on the two lateral apices. Its surface with some transversal wrinkles. Lamellae very wide, with a complicated structure (Fig. 1), their lateral apex with small teeth, median apices auriculate, but not touching medially. Between the lamellar apices there is a deep incision bearing lamellar seta. Interlamellar setae arising on the lamellar surface. Sensillus short, setiform, sligthly dilated medially, unilaterally ciliated, directed * This work was also sponsored by the Hungarian Scientific Research Fund (OTKA 16729).
