The only exception is the position of the stigma, which is located almost in the middle between the valve center and valve margin. This makes it similar to L. madagascarensis, however, the latter species has external proximal raphe endings with long and distinct grooves on a side opposite the stigma; these grooves are indistinct in L. halongiana. Also, Luticola mutica (Kützing) D.G.Mann shows some similarities to L. halongiana sp. nov. but it can be easily distinguished based on the narrower central area. Also L. mutica has areolae containing cribrum which is not present in described species.</p> <p>Morphological characteristic of recently established Luticola taxa observed during this study.</p> </div>	http://treatment.plazi.org/id/9F289AD4A8855E3EA510E17A4D0BF91D	Public Domain	No known copyright restrictions apply.
