Remarks

• Systematics: Generic characteristics that distinguish this genus from all other eriococcids are: aggregated in clusters around margin similar to cerarii; enlarged setae; antennae 3-segmented (Reyne, 1961; Williams & Watson, 1990). Pedroniopsis Green, described from Sri Lanka, also possesses 3-segmented antennae and has truncate-conical setae. However, these setae are not in marginal groups as in Sangicoccus. (Kozár, et al., 2009)
• Structure: Body of adult female on microscope slide broadly oval, membranous. Venter: Antennae short, 3 segmented, gently tapering. Frontal lobes present, well developed. Labium apparently unsegmented, with minute setae on eip. Loculate disc pores, each with 5-10 loculi, scattered over most of surface, or in marginal groups; absent medially on head, thorax and anterior abdominal segments. Legs not well developed, short; trochanter and femur usually fused; hind coxa and femur with large irregularly shaped translucent pores on posterior surfaces. Macrotubular ducts long and narrow, each with wide sclerotized area surrounding orifice; present sparsely on abdomen, each inner ductule shorter than length of outer ductule, terminating in a circular gland. Instead of cruciform pores, moditied microtubular ducts present in a submedial band. Setae few, short and pointed. Dorsum: Marginal setae spine-like, conical, usually truncate, sometimes bluntly pointed; present in large groups around margin, each on an area of sclerotized derm. Dorsal setae numerous, of 2 types, one type wide spine-like, and other narrow spine-like. Anal lobe segment and anal lobes displaced only dorsum and surrounding anal ring. Anal lobes barely discernible, each with 2 long flagellate setae and 2 spine-like setae. Anal ring sclerotized, with a small number of pores in a single row, plus 6 anal ring setae, each longer than the diameter of the ring. Cauda apparently represented by an undetached lobe anterior to the anal ring. Disc pores each with 5-7 loculi, few and scattered on posterior abdominal segments and forming a sparse marginal submarginal band. Macrotubular ducts absent. Small and short microtubular ducts present scattered. (Kozár, et al. 2009)
• General Remarks: Detailed description in Kozár, et al., 2009.
