Mictyridae Dana, 1851

Mictyris longicarpus Latreille, 1806 ( Fig. 27 ) and Mictyris platycheles H. Milne Edwards, 1852

Ossicles I and II are inclined about 45° in the antero ventral direction. The pterocardiac ossicle (II) is nearly completely connected with the antero lateral margin of the mesocardiac ossicle (I); laterally it extends in the form of two tips to the prepectinal ossicle (IX) as well as to the zygocardiac ossicle (V). The exopyloric ossicle (IV) is comparatively large. The unpaired propyloric ossicle (VI) is inclined about 45° in the posterior direction. The pectinal ossicle (VIII) is ring-shaped with 19 accessory teeth. The median and postero ventral parts of the prepectinal ossicle (IX) are enlarged. The inferior lateral cardiac ossicle (XIII) has a long oval shape and two ventrally directed crossed tips; postero dorsally it has a posteriorly directed connection-piece. The lateral ossicle of the cardio-pyloric valve (XVIII) is greatly enlarged and covers the lateral side of the cardio-pyloric valve. Ossicle XVII is not recognisable.
