Remarks

• Systematics: Slide-mounted adult female with: enlarged setae of 2 kinds, shorter cylindical setae with sides slightly concave, apices truncate, aggregated in clusters around margin similiar to cerarii, other kind of seta elongate, cylindrical, apices rounded, of 2 sizes, larger in medial areas of anterior abdomen, thorax, and head, smaller size scattered over rest of abdomen; anal lobes each with 2 to 8 enlarged setae; antennae 3-segmented; frontal lobes present; microtubular ducts without sclerotized areas, orifice of those on venter 8-shaped (Reyne, 1961; Williams & Watson, 1990). There is probably much variation in some characters in this species: the size of the three anterior=most groups of truncate-conical setae, the total number of marginal groups of setae vary from 11 to 13, and the distribution of the translucent pores on the hind legs. The holotype possesses 12 truncate-conical setae on each posteriormost group whereas others may have only six or seven. (Kozár, et al. 2009)
• Structure: Adult female broadly oval (Williams & Watson, 1990), and has white wax on the dorsum, and has thin wax filaments along the margin of the body. Abundant sooty mold accompanied the insect. Adult males are red (Reyne, 1961). Antennae 3 segmented, all segments with a few short setae; segment II with sensory pore; apical segment with several apical setae, plus 4 falcate sensory setae. Frontal lobes present, large. Eyes present near ventral margin. Venter: Labium unsegmented, with minute setae present on tip. Legs short and not well developed. All coxae with spinulae; hindcoxae and femora each with several large, irregularly-shaped translcent pores on both surfaces; each trochante with 2 pores on each side; claws each cuved, with stout basal half, each with denticle. All legs with a few hai-like setae and with 1 sensory pore proximally on each tarsus. Spiracles with a few associated disc pores. Locular disc pores with 5-7 loculi in segmental bands medially across abdominal segments VI-VIII, and scatteed along etire submargin. setae few, short, hair-like. Instead of cruciform pores, modified microtubular ducts present, fairly abundant. Macrotubular ducts present submarginally on some abdominal segments, each with a wide sclerotized rim surrounding orifice and with inner ductule shorter than outer ductule, ending with a circular gland. Anal lobes each apparently without subapical seta, short suranal seta present. Dorsum: Marginal setae truncate-conical present in 11 compact groups, more or less equispaced, each on a sclerotised area of derm. Dorsal setae of two main sizes: larger spine-like setae robust, each bluntly pointed with a striated surface, present in 2 longitudinal rows of about 11-12 spines on midline, and also sparsely in a norrow band of about 16 spines just mesad to marginal groups of truncate setae; smaller setae, each robust but more slender, evenly distributed throughout and faily numerous. Macrotubular ducts absent. Microtubular ducts present among dorsal setae and with several near bases of some truncate-conical seta although not so closely associated as in S. morrisoni or S. reynei. Locular disc pores with 5-7 toculi present on almost all segments of abdomen. Anal ring with a sparse row of pores plus 6 flagellate anal ring setae. Anal lobes forming a naow band, almost encircling anal ring, each with 2 truncate spine-like setae on inner margin and 2 apical setae. Cauda present but not distinct. (Kozár et al., 2009)
