bilocular (Fig. 92, E) and disc pores (Fig. 92, F)
scattered over derm. Body setae (Fig. 92, C) scat-
tered, slender, straight, pointed, base smaller
than those of marginal setae. Large discoidal
pores (Fig. 92, G) anterior and laterad to anal
area. Anal plates triangular; cephalolateral
margin longer than caudolateral margin.
VENTER -Antennae greatly reduced. Legs
greatly reduced. Spiracles larger than legs. Quin-
quelocular and multilocular pores (Fig. 92, L,
M) nearly same size in spiracular furrows, most
pores with 10-loculi in vulvar region. Tubular
ducts (Fig. 92, O, P, Q) of 2 sizes on abdomen.
MARGIN -Marginal setae (Fig. 92, B) few, about
16 between anterior spiracular setae, each seta
slender, pointed, with large base. Spiracular
setae (Fig. 92, D) normally in groups of 3, occa-
sionally 4 present, setae nearly same size.

Map XXXVIII. Distribution of Toumeyella cerifera.


ECONOMIC IMPORTANCE: Probably not
economically important in Florida.
REMARKS: The first record of this scale in the
U. S. was from Virginia (Williams & Kosztarab
1972). Ferris (1921) stated that the original
material from Mexico had a distinct ovisac, but
was nevertheless a Toumeyella. The Virginia
material of Williams and Kosztarab (1972) gave
birth to live young and produced no ovisac.


 Toumeyella cerifera can be separated from
the other species of Toumeyella in Florida
because of 10-loculi multi ocular pores in the
spiracular furrows and vulvar area.

COMMON NAME: tuliptree scale
FIELD DESCRIPTION: Female extremely con-
vex, oval, irregular in outline when crowded on
stem. Color extremely variable from grayish-
green to a pink-orange to brown or black (Fig.
93, A, B). According to Merrill (1953), they look
much like a cattle tick.
DESCRIPTION: (Fig. 94) Adult female subcir-
cular, 2.5-6.0 mm in diameter. DoRsM -Derm
heavily sclerotized only around anal plates.
Numerous bilocular pores (Fig. 94, D) and small
discoidal pores (Fig. 94, E). Body setae spinelike,
apically pointed, similar to marginal setae (Fig.
94, B), slightly shorter. Large discoidal pores
(Fig. 94, F) scattered in median area from
anterior to anal plates, to above rostrum and
laterally into submedial areas. Anal plates
triangular with cephalolateral margins concave,
with 4 apical setae, 5-7 subapical setae; anal fold
with 2 pair fringe setae. VENTER-Spiracles
larger than legs. Quinquelocular pores (Fig. 94,
K) very numerous in spiracular furrows, vulvar
area, and in broad submedial band on preceding
abdominal segments to posterior spiracle.
Tubular ducts (Fig. 94, M) with slender fila-
ment, numerous in vulvar area.
