Systematics: In Florida (USA), N. cornuparvum may be difficult to distinguish from the tuliptree scale, Toumeyella liriodendri. However, in T. liriodendri the quinquelocular pores are found in the perivulvar region and last 1 or 2 abdominal segments and also in a line of pores that extend up to the posterior spiracles and around the meso- and metathoracic legs. (Kondo & Buss, 2022)
Structure: Adult female oval to elongate oval (shape often irregular due to crowding); young specimens flat, becoming highly convex with maturity, 0.4–1.25 cm long; colour ranging from cream, through light yellow to pink-orange, old specimens becoming completely dark. Teneral adult females with a smooth, bare surface but soon becoming dusted with copious white powdery wax; when removed from feeding site, leaving 4 white waxy lines corresponding with positions of spiracular furrows. Males are found intermixed with the females, their puparia are elongate oval, slenderer, composed of glassy waxy plates; the adult males have a pair of well-developed wings. (Kondo & Buss, 2022)
Biology: Usually found on twigs and branches of Magnolia species. (Kondo & Buss, 2022)
General Remarks: Good description and illustration of the adult female given by Williams & Kosztarab (1972), Hamon & Williams (1984) and by Kosztarab (1996).
