first proposed as a subgenus of Lecanium.
Steinweden (1929) concluded that Neolecanium,
Pseudophilippia, and Toumeyella constituted a
single genus. The generic characters given here
refer only to Neolecanium cornuparvum (Thro)
because it is the only species of the genus which
occurs in the United States. The genus
Neolecanium must be revised before its true rela-
tionship to the genus Toumeyella can be
understood. For a description of the immature
stages and adult male of N. cornuparvum see Ray
and Williams (1982).

SYNONYMS:

 Neolecanium cornuparvum
 (Thro), Fernald 1903:176,
 Ray and Williams 1983:161
COMMON NAME: magnolia scale
FIELD DESCRIPTION: Williams & Kosztarab
(1972) indicated that females are very large,
reaching a length of 12.5 mm. The shape is ellip-
tical and flat to convex. Younger, developing
females are pink-orange and darker around the
margin. Old females are usually covered with a
white bloom or mealy wax (Fig. 51); very old
females are brown.


(Williams & Kosztarab 1972). DORSM -Older
females have slightly sclerotized derm, heavier
sclerotization around anal plates. Numerous
small 8-shaped pores (Fig. 52, E. F), each in a
clear area on dorsal surface. Body setae (Fig. 52,
C) short, stout, pointed, randomly scattered.
Many small disc pores scattered over dorsum.
Large discoidal pores (Fig. 52, H) scattered over
derm anterior to anal plates and extending to just
above mouthparts. Anal plates (Fig. 52, Ii)
triangular with all angles rounded.
VENTER-Submarginal setae short, slender,
pointed, 9 between spiracular furrows. Antennae
short, stout, 6-segmented, segmentation often
obscure. Legs short, stout, segmentation fre-
quently obscure. Spiracles longer than legs.
Spiracular furrows with band of quinquelocular
pores (Fig. 52, N), 15-20 pores wide near
margin, becoming narrower near spiracles.
Tubular ducts (Fig. 52, P) numerous in vulvar
area. Quinquelocular pores (Fig. 52, N)
numerous in vulvar area. MARGIN Marginal
setae (Fig. 52, B) slender, pointed, straight or
curved at apex, about 16 between anterior and
posterior spiracular furrows. Spiracular setae
(Fig. 52, D) 3 at apex of each spiracular furrow,
each short, stout, conical, sometimes notched at
apex; median seta slightly larger than laterals.
