II: Descriptions of six new species — Six oribatid mite species of the genera Microtegeus, Hymenozetes, Austrocarabodes, Leptoppia, Oripoda, Pseudopirnodus are described from Madagascar, all new to science. INTRODUCTION In a continuing elaboration of the oribatid fauna of Madagascar, in the following I describe six new species of different genera. The aim and the circumstances of this work were published in my earlier papers (e.g., Mahunka 1993, 1994). DISCUSSION AND DESCRIPTIONS OF SPECIES Microtegeus cervus sp. n. Measurements — Length of body: 243-255 urn, width of body: 142-148 urn. Integument: Nearly the whole body surface covered by partly granulated cerotegument layer. The surface of the legs free. Prodorsum: Rostrum conical. Lamellae strongly narrowing anteriorly, with well developed, arched, spiniform lamellar cusp. It is separated by a deep incisure from the rostral apex (Fig. 5). Lamellar surface ornamented by irregular wrinkles and pustules, similar ones also present in the dorsosejugal region. Interlamellar region mostly smooth. Rostral setae small, unobservable from dorsal aspect. Lamellar setae spiniform, slightly, arched inwards, interlamellar setae thin, arising on the lamellar surface. Sensillus elongated, its dorsal surface with blunt spines. Notogaster: Three pairs of large, but not high projections (clearly visible under lower magnification) on the notogaster (Fig. 1). Its surface covered also by pustules and granules like the prodorsal ones. Ten pairs of slightly spiniform, short notogastral setae present; position typical for the family. Lateral part of prodorsum: Pedotecta I large, on their surface with a polygonal pattern (Fig. 4). Pedotecta 11

—111 very large. Exobothridial setae with distinct branches. Ventral regions (Fig. 2): Coxisternal region strongly sclerotised, all epimeral borders and the apodemes, excepting the third, well observable. Epimeral borders with a characThis work was sponsored by the Hungarian National Scientific Research Fund (OTKA: T 16729).
