increasing in size to wards the median region. Sensillus (Fig. 18) long, with lanceolate head. Rostral setae long, setiform and smooth, overlapping medially. Interlamellar setae bacilliform, erect, their distal half spinose, lamellar setae minute, very thin, hardly observable. Exobothridial setae represented only by their alveoli. Bothridial squama waved. Notogaster: 15 pairs of bacilliform, notogastral setae similar to interlamellar ones present, reduced setae fj and f 2 visible. Four pairs of elongate lyrifissures also observable. Surface densely foveolate, foveolae partly connected with each other (Fig. 16). Anogenital region (Fig. 20): Genital setae gradually shortened anteriorly. Surface of genital plates similar to that of notogastral one, but on ano-adanal plates foveolae gradually passing into slits and furrows (Fig. 21). Both pairs of anal setae and setal adj arising in a longitudinal line, near to the inner margins of plates: setae ad 2 far from these. Setae adj and ad2 nearly equal in length. Material examined: Holotype (1174-HO-86): No. 74; five paratypes: from the same sample. Holotype and three paratypes (1174-PO-86) deposited in the HNHM, one paratype in MHNG and one paratype in NHMN. Remarks: The new species is well characterized by the shape of the prodorsal setae and the sculpture of the ano-adanal plates. This combination of features and any similar sculpture have so far been unknown in the related Hoplophthiracarus species. Hoplophoph th iracarus hamidi sp. n. Measurements. - Length of aspis: 246-369 /im, length of notogaster: 475-762 jum, height of notogaster: 287-469 jum. Aspis: Low in lateral view, its lateral margin gradually disappearing anteriorly. A clearly visible, but thin and not straight lateral carina also present, it begins at the dorsal margin of the bothridium (Fig. 2 3). Surface with some weak alveoli anteriorly and with weak rugae basally. Rostral setae thick, barbed, interlamellar setae slightly longer but thinner, Figs 24-26.
