陆生等足目第二触角鳞片的超微结构

Ultrastructural Studies on the Scales of the Second Antennae of Terrestrial Isopods

通过对５种陆生等足目（隶属４科４属）第二触角扫描电镜的观察，尤其对触鞭的观察，发现第二触角覆被鳞片、其鳞片按其外形可分为长条形、三角形、椭圆形、近方形、扇形、铲形、长矛形等７种；按其鳞片表面是否光滑可分为光滑型和具肋型，后者又可分为整体具肋型和边缘具肋型．

The second antennae of terrestrial isopods are highly modified in adaptation to terrestrial life, so they are the important factors to classification of terrestrial Isopoda. By means of SEM, the scale ultrastructure of the scecond antennae of Oniscoicea (5 specieses) are studied. The scales of the antennule can be classifiedv o 7 types, which are narrowrectangle, triangle, ellipseinearly-sure,sector, shovel - like and pike - like shape, according to their contours.According to their surface the scales can be Classfied to smooth type and ribbed type which can further be divided fo wholt-ribbed surface type and edgyribbed one.
