Fig 2. Anoetostoma nerminka sp. n. - A: leg I, B: leg II, C: leg III, D: leg IV, E: terminal seta of leg V Remarks. - The new species stands very near to Anoetostoma domrowi Fain, 1967, but may be distinguished from it by the presence of dorsosejugal region, the number of suckers on suctorial plate, the shape and the ornamentations of its apodemes and the robust claws on legs III and IV. Histiostoma pickaxei sp. n. (Figs 3-4) This species belongs in the alliance of Histiostoma adarculae Mahunka, 1979; this group of species is well characterizable by the peculiar sculpture of the prodorsum, the high arched epimere 3, the conspicuous length of solenidion e on leg I, and the widely phylliform terminal hairs of leg III. The group comprises H. adarculae Mahunka, 1970, H. arcuatum Mahunka, 1963, H. Impressum Mahunka, 1963, H. ceylanense Mahunka, 1973 and H. decorum Mahunka, 1967; the new species stands nearest to H. adarculae, but differs from it by the shape of apodemes 3 and sejugal apodemes and the pickaxeshaped of setae I2" on legs I and II. Measurements. - Length: 178-184 [im, breadth: 121-131 um. Dorsal side (Fig. 3: A). - Rostrum slightly differentiated from prodorsum, but still rounded, prodorsal surface with characteristic pattern of arcuate lines. Dorsosejugal re-
