COMMON NAME: long brown scale
FIELD DESCRIPTION: Adult female (Fig. 35)
elongate-oval, moderately convex and smooth.
Color yellowish to grayish-brown (Merrill 1953).
Eyes usually visible.
DESCRIPTION: (Fig. 36) Adult female
elongate, 2.0-6.0 mm long, 1.0-3.0 mm wide
(Gill et al. 1977). DoasuM-Derm membranous
or slightly sclerotized with many clear areas.
Eyespots surrounded by oval pale areas. Sub-
marginal tubercles (Fig. 36, L) number 9-19.
Dorsal setae (Fig. 36, K) short, curved, pointed,
scattered over surface. Microducts few, usually
associated with small clear area.' Anal plates
(Fig. 36, G1) with cephalolateral margins usually
concave, shorter than caudolateral margins,


each plate with 3 subapical, 3 apical, 1 subdiscal
setae. VENTER-Derm membranous. Antennae
8-segmented. Legs well developed with tibiotar-
sal scleroses. Tubular ducts absent. Microducts
(Fig. 36, B) sparse, slight concentration
alongside mouthparts. Multilocular pores (Fig.
36, F) in vulvar area only, mostly with 6-7 loculi.
MARGIN-Marginal setae (Fig. 36, 0) slender,
curved, set far apart, mostly acute, few bifur-
cate, 3-4 fimbriate near anal cleft (Gill et al.
1977). Spiracular setae (Fig. 36, M) 3, with me-
dian seta 2-3X longer than laterals.
DISTRIBUTION: Map XI. AL, CA, DC, DE,
GA, HI, IL, LA, MA, MD, MO, NY, OH, PA,
TX. Foreign: China, Colombia, Ecuador, Hon-
duras, Lebanon, Mexico, Oceania, Philippines,
Puerto Rico, Samoa, Taiwan, and Virgin Is-
lands. Widespread in the tropics and semi-
tropical areas of the world (Gill et al. 1977).

BIOLOGY: According to Gill et al. (1977), little
is known about the life history of this species. It is
found on the branches, leaves, and stems of host
plants.
ECONOMIC IMPORTANCE: Not considered
an economic pest in Florida (Merrill, 1953). Only
light infestations have been observed during the
last few years in Florida.
REMARKS: According to Gill et al. (1977), C.
longulus may resemble Eucalymnatus tesselatus
(Signoret) before E. tesselatus becomes sclero-
tized. Coccus longulus is less convex and more
elongate than brown soft scale (C. hesperidum).
